Question: What happens when an American Mayor dies?

Mayor


In many countries, a mayor  (from the Latin maior [majˈjɔr], meaning "bigger") is the highest-ranking official in a municipal government such as that of a city or a town.
Worldwide, there is a wide variance in local laws and customs regarding the powers and responsibilities of a mayor as well as the means by which a mayor is elected or otherwise mandated. Depending on the system chosen, a mayor may be the chief executive officer of the municipal government, may simply chair a multi-member governing body with little or no independent power, or may play a solely ceremonial role. Options for selection of a mayor include direct election by the public, or selection by an elected governing council or board.
History
British Isles

In modern England and Wales, the position of mayor descends from the feudal lord's bailiff or reeve (see borough). The chief magistrate of London bore the title of portreeve for considerably more than a century after the Norman Conquest. This official was elected by popular choice, a privilege secured from King John. By the beginning of the 12th century, the title of portreeve gave way to that of mayor as the designation of the chief officer of London, followed around 1190 by that of Winchester. Other boroughs adopted the title later. In the 19th century, in the United Kingdom, the Municipal Corporations Act 1882, Section 15, regulated the election of mayors. The mayor was to be a fit person elected annually on 9 November by the council of the borough from among the aldermen or councillors or persons qualified to be such. His term of office was one year, but he was eligible for re-election. He might appoint a deputy to act during illness or absence, and such deputy must be either an alderman or councillor. A mayor who was absent from the borough for more than two months became disqualified and had to vacate his office. A mayor was ex officio a justice of the peace for the borough during his year of office and the following year. He received such remuneration as the council thought reasonable. These provisions have now been repealed.
In medieval Wales, the Laws of Hywel Dda codified the mayor (Latin: maior; Welsh: maer) as a position at the royal courts charged with administering the serfs of the king's lands. To maintain its dependence on and loyalty to the Crown, the position was forbidden to the leaders of the clan groups.[1] A separate mayor, known as the "cow dung mayor" (maer biswail), was charged with overseeing the royal cattle.[1] There were similar offices at the Scottish and Irish courts.
The office of mayor in most modern English and Welsh boroughs and towns did not in the 20th century entail any important administrative duties, and was generally regarded as an honour conferred for local distinction, long service on the Council, or for past services. The mayor was expected to devote much of his (or her) time to civic, ceremonial, and representational functions, and to preside over meetings for the advancement of the public welfare. His or her administrative duties were to act as returning officer at parliamentary elections, and as chairman of the meetings of the council. However, since reforms introduced in 2000, 14 English local authorities have directly elected mayors who combine the 'civic' mayor role with that of Leader of the Council and have significantly greater powers than either. The mayor of a town council is officially known as "town mayor" (although in popular parlance, the word "town" is often dropped). Women mayors are also known as "mayor"; the wife of a mayor is sometimes known as the "mayoress". Mayors are not appointed to District Councils which do not have borough status. Their place is taken by the Chairman of Council, who undertakes exactly the same functions and is, like a mayor, the civic head of the district concerned.
In Scotland the post holders are known as Convenors, Provosts, or Lord Provosts depending on the local authority.
Continental Europe

The original Frankish mayors or majordomos were – like the Welsh meiri – lords commanding the king's lands around the Merovingian courts in Austrasia, Burgundy, and Neustria. The mayorship of Paris eventually became hereditary in the Pippinids, who later established the Carolingian dynasty.
In modern France, since the Revolution, a mayor (maire) and a number of mayoral adjuncts (adjoints au maire) are selected by the municipal council from among their number. Most of the administrative work is left in their hands, with the full council meeting comparatively infrequently. The model was copied throughout Europe in Britain's mayors, Italy's sindacos, most of the German states' burgomasters, and Portugal's presidents of the municipal chambers.
In Medieval Italy, the city-states who did not consider themselves independent principalities or dukedoms – particularly those of the Imperial Ghibelline faction – were led by podestàs.
The Greek equivalent of a mayor is the demarch (Greek: δήμαρχος, lit. "archon of the deme").
Scandinavia
In Denmark all municipalities are led by a political official called borgmester, "mayor". The mayor of Copenhagen is however called overborgmester "superior mayor". In that city other mayors, borgmestre (plural), are subordinate to him with different undertakings, like ministers to a prime minister. In other municipalities in Denmark there is only a single mayor.
In Norway and Sweden the mayoral title borgermester/borgmästare has now been abolished. Norway abolished it in 1937 as a title of the non-political top manager of (city) municipalities and replaced it with the title rådmann ("alderman" or "magistrate"), which is still in use when referring to the top managers of the municipalities of Norway. The top elected official of the municipalities of Norway, on the other hand, has the title ordfører, which actually means "word-bearer", i.e. "chairman" or "president", an equivalent to the Swedish word ordförande.
In Sweden borgmästare was a title of the senior judge of the courts of the cities, courts which were called rådhusrätt, literally "town hall court", somewhat of an equivalent to an English magistrates' court. These courts were abolished in 1971. Until 1965 these mayor judges on historical grounds also performed administrative functions in the "board of magistrates", in Swedish known collegially as magistrat. Until 1965 there were also municipal mayors (kommunalborgmästare), who had these non-political administrative roles in smaller cities without a magistrates' court or magistrat. This office was an invention of the 20th century as the smaller cities in Sweden during the first half of the 20th century subsequently lost their own courts and magistrates.
In the 16th century in Sweden, king Gustav Vasa considerably centralised government and appointed the mayors directly. In 1693 king Charles XI accepted a compromise after repeated petitions from the Estate of the Burgesses over decades against the royal mayor appointments. The compromise was that the burgesses in a city could normally nominate a mayor under the supervision of the local governor. The nominee was then to be presented to and appointed by the king, but the king could appoint mayors directly in exceptional cases. This was codified in the Instrument of Government of 1720 and on 8 July the same year Riksrådet ("the Council of the Realm") decided, after a petition from the said Estate, that only the city could present nominees, not the king or anyone else. Thus the supervision of the local governor and directly appointed mayors by the king ceased after 1720 (the so-called Age of Liberty). On 16 October 1723, it was decided after a petition that the city should present three nominees, of whom the king (or the Council of the Realm) appointed one.[2] This was kept as a rule from then on in all later regulations[2] and was also kept as a tradition in the 1809 Instrument of Government () until 1965.
In Finland, there are two mayors, in Tampere and Pirkkala. Usually in Finland the highest executive official is not democratically elected, but is appointed to a public office by the city council, and is called simply kaupunginjohtaja "city manager" or kunnanjohtaja "municipal manager", depending on whether the municipality defines itself as a city. The term pormestari "mayor", from Swedish borgmästare confusingly on historical grounds has referred to the highest official in the registry office and in the city courts (abolished in 1993) as in Sweden, not the city manager. In addition, pormestari is also an honorary title, which may be given for distinguished service in the post of the city manager. The city manager of Helsinki is called ylipormestari, which translates to "Chief Mayor", for historical reasons. Furthermore, the term "city manager" may be seen translated as "mayor".
Mayors by country
Australia
On Australian councils, the mayor is generally the member of the council who acts as ceremonial figurehead at official functions, as well as carrying the authority of council between meetings. Mayoral decisions made between meetings are subject to Council and may be confirmed or repealed if necessary. Mayors in Australia may be elected either directly through a ballot for the position of mayor at a local-government election, or alternatively may be elected from within the council at a meeting.
The civic regalia and insignia of local government have basically remained unaltered for centuries.
The robes, the mayoral chain and the mace are not intended to glorify the individual, but rather they are a uniform of office and are used to respect and honour the people whom the users serve.
The mayoral robe may be crimson with lapels and sleeves trimmed in ermine. The mayor may also wear a lace fall (neck piece) and cuffs.
The deputy-mayoral robe may be crimson with lapels and sleeves trimmed with black velvet and bordered with lapin.
Mayors have the title of 'His/Her Worship' whilst holding the position.
In councils where Councillors are elected representing political parties, the mayor is normally the leader of the party receiving the most seats on council. In Queensland the Lord Mayor and Mayors are elected by popular vote at the general council election.
Brazil
Every municipality in Brazil elects a mayor (Portuguese: prefeito/prefeita), for a four-year term, acting as an executive officer with the city council (Portuguese: Câmara Municipal) functioning with legislative powers. The mayor can be re-elected and manage the city for two consecutive terms.
The Brazilian system works similarly to the mayor-council government in the United States.
Canada
The chief executives of boroughs (arrondissements) in Quebec are termed mayors (maires/mairesses in French). A borough mayor simultaneously serves as head of the borough council and as a regular councillor on the main city council.
As is the practice in most Commonwealth countries, in Canada a mayor is addressed as His/Her Worship while holding office.
In some small townships in Ontario, the title reeve was historically used instead of mayor. In some other municipalities, "mayor" and "reeve" were two separate offices, with the mayor retaining leadership powers while the reeve was equivalent to what other municipalities called an "at-large councillor". While most municipalities in the province now designate their elected municipal government heads as mayors, in certain areas of the province, the elected head of the municipality continues to be refereed to as reeve, and the second-in-command is referred to as the deputy reeve. For example, this continues to be the case in the municipalities of Algonquin Highlands, Dysart et al, Highlands East, and Minden Hills, all located within the Haliburton County.
Many municipalities in Alberta continue to use the title reeve to denote the office of mayor or chief elected official in accordance with the Municipal Government Act.
In rural municipalities (RM) in the provinces of Manitoba and Saskatchewan, the elected head of the RM is still referred to as a "reeve", as are the heads of most counties and district municipalities (DMs) in Alberta.
The scheduling of municipal elections in Canada varies by jurisdiction, as each province and territory has its own laws regarding municipal governance. See also municipal elections in Canada.
Dominican Republic
The mayor of a municipality in the Dominican Republic is called indistinctly alcalde or síndico. The latter name is preferred as to avoid confusing the title with the similarly sounding alcaide (lit. prison warden). Such person is the governor of the municipality whose township elected him (or her) by direct vote for a term of four years. The mayor's office daily duties are restricted to the local governance, and as such, it is responsible for the coordination of waste collection, upkeep of public spaces (parks, undeveloped urban parcels, streets, city ornate, traffic light control, sewage and most public utilities). In practice most of it duties are centered in light street repairing (new or big road projects, like overpasses, bridges, pedestrian crossings, etc. are handled by the Public Works Ministry (Ministerio de Obras Públicas in Spanish) office), under the direct control of the Central Government. Subcontracting garbage collection and management, overseeing the use of public spaces and arbitring neighborhood land use disputes which is managed by the National Property office (Oficina de Bienes Nacionales in Spanish) is also controlled by the mayor's office. Water, electrical supply and public transportation coordination are handled by several Central Government's offices, and as such, are not under control of the mayor.
France

Mayors (maires) in France are elected every six years in local elections.
Germany
In Germany local government is regulated by state statutes. Nowadays only the mayors of the three city-states (Berlin, Hamburg and Bremen) are still elected by the respective city-state parliaments. In all the other states the mayors are now elected directly by the EU citizens living in that area. The post of mayor may be said to be a professional one, the mayor being the head of the local government, and requiring, in order to be eligible, a training in administration. In big cities (details are regulated by state statutes) the official title is Oberbürgermeister (Lord Mayor). In these cities a "simple" mayor is just a deputy responsible for a distinct task (e.g., welfare or construction works). Big cities are usually kreisfrei ("free of district"). That means that the city council also has the powers and duties of a rural district council. The leader of a rural district council is called Landrat ("land counsellor"). In that case the chief mayor has also the duties and powers of a Landrat. The term Oberbürgermeister is not used in the three city-states, where the mayors are simultaneously head of state governments, but Regierender Bürgermeister (Governing Mayor of Berlin), Erster Bürgermeister (First Mayor of the city-state of Hamburg) and Präsident des Senats und Bürgermeister (President of the Senate and Mayor of Bremen) are used.
Greece
Mayors in Greece were elected every four years in local elections and are the head of various municipal governments in which the state is divided. Starting from 2014, mayors are elected for a 5-year term. Local administration elections for the new, consolidated municipalities and peripheries will henceforth be held together with the elections for the European Parliament.
Local administration in Greece recently underwent extensive reform in two phases: the first phase, implemented in 1997 and commonly called the "Kapodistrias Project", consolidated the country's numerous municipalities and communities down to approximately 1000. The second phase, initially called "Kapodistrias II" but eventually called the "Callicrates Project", was implemented in 2010, further consolidated municipalities down to 370, and merged the country's 54 prefectures into 13 peripheries. The Callicratean municipalities were designed according to several guidelines; for example each island (except Crete) was incorporated into a single municipality, while the majority of small towns were consolidated so as to have an average municipal population of 25,000.
India
In India, the mayor is leader of the council and has a number of roles, both legislative and functional. The legislative requirements are outlined in Section 73 and 73AA of Local Government Act 1989. In most Indian states mayors are elected indirectly among the council members themselves except in eight states Bihar, Chhattisgarh, Haryana, Jharkhand, Madhya Pradesh, Odisha, Uttar Pradesh and Uttarakhand; where mayors are elected directly by the public.
Indonesia
In Indonesia, mayor (Indonesian: wali kota, formerly called walikotamadya and walikota) is a regional head of a city or town. A mayor has the same level as a regent (Indonesian: bupati), head of a regency (Indonesian: kabupaten). Basically, a mayor has duties and authority to lead the implementation of the policies established by the region along with the city council (Indonesian: Dewan Perwakilan Rakyat Daerah Kota, DPRD Kota; formerly called Tier 2-DPRD (DPRD tingkat II)). A mayor is elected in a pair with a vice mayor through direct elections and is a political office, except in Jakarta. There, mayoralty is a civil-service career position with limited authority and is designated by the Governor of Jakarta. Their region are called administration cities (Indonesian: kota administrasi).
Before 1999, there were administrative cities (Indonesian: kota administratif, id) which were headed by administrative mayors.
Iran
In Iran, the mayor is the executive manager of city and elected by the Islamic City Council. The mayor is elected for a four-year term.
Ireland
In the Republic of Ireland, the head of a borough corporation was called "mayor" from the Municipal Corporations (Ireland) Act 1840 until boroughs were abolished by the Local Government Reform Act 2014. The Local Government Act 2001 allowed county councils to style their chairperson as "mayor" and most do so. City council chairs are "mayor" (or "lord mayor" in the cases of Dublin and of Cork). Since 2000 there have been proposals for a directly elected mayor of the Dublin Metropolitan Area.
Italy
In Italy the mayor is called sindaco, or informally primo cittadino ("first citizen"). Every municipality (Italian: Comune) has its mayor who represents the local government. The mayor is elected every five years by the inhabitants of the municipality, but he cannot be re-elected after two terms (except in small towns).[3]
Japan
Japan's Local-Autonomy Law of 1947 defines the structure of Japanese local governments, which were strengthened after World War II. It gives strong executive power to the mayor in the local politics like strong mayors in large cities in the United States of America.
The titles that are translated as "mayor" by the governments are those of the heads of cities shichō(市長), towns chōchō(町長), villages sonchō(村長), and Tokyo's special wards kuchō(区長).
(The head of the Tokyo prefecture is the Governor(知事,Chiji).)
A mayor is elected every four years by direct popular votes held separately from the assembly. A mayor can be recalled by a popular initiative but the prefectural and the national governments cannot remove a mayor from office. Towards the assembly the mayor prepares budgets, proposes local acts and has vetoes on local acts just approved by the assembly which can be overridden by two-thirds assembly support. A mayor can resolve the assembly if the assembly passes a motion of no confidence or if the mayor thinks the assembly has no confidence in fact.
Kazakhstan
In Kazakhstan, the mayor is called Akim who is the head of an akimat, a municipal, district, or provincial government (mayorat), and serves as the Presidential representative. Akims of provinces and cities are appointed to the post by the President on the advice of the Prime Minister. Meanwhile, the akims of other administrative and territorial units are appointed or selected to the post in an order defined by the President. He may also dismiss akims from their posts. Powers of akims ends with the introduction into the post of new-elected president of the republic. Thus, the akim continues to fulfill the duties before appointment of corresponding akim by the President of Kazakhstan.
Malaysia

The mayor functions as the head of the local government of the cities in Malaysia. To date, there are 14 officially-recognised cities in the country.
In cities which lie within the jurisdiction of any one of the 13 Malaysian states, the mayor is appointed by the state government.[4] Kuala Lumpur, the country's capital, is a notable exception, as it forms part of the Federal Territories which come under the purview of the Malaysian federal government, via the Ministry of Federal Territories. Thus, the mayor of Kuala Lumpur is selected by, and subordinate to, the Minister of Federal Territories.[5]
Following the 2018 general election, which saw the country undergoing its first ever regime change, there have been calls to revive local government elections, which had been the practice in certain cities such as Kuala Lumpur, George Town, Ipoh and Melaka until their abolishment in 1965.[4][6][7] The reinstatement of local government elections would lead to the mayoral position being elected, instead of being appointed as per the current system.
Malta
In Malta, the mayor (In Maltese: Sindku) is the leader of the majority party in the Local Council. The members of the Local Councils are directly elected and collectively serve as a basic form of local government.
Moldova
The Mayor of the municipality in Moldova is elected for four years. In Chişinău, the last mayor elections had to be repeated three times, because of the low rate of participation.
Netherlands

In the Netherlands, the mayor (in Dutch: burgemeester) is the leader of the municipal executives ('College van Burgemeester en Wethouders'). In the Netherlands, burgermeesters are de facto appointed by the national cabinet, de jure by the monarch. They preside both the municipal executive and the legislative ('gemeenteraad'). The title is sometimes translated as burgomaster, to emphasize the appointed, rather than elected, nature of the office. The appointment procedure was brought for discussion in the early 2000s (decade), as some of the political parties represented in parliament regarded the procedure as undemocratic. Generally, mayors in the Netherlands are selected from the established political parties. Alternatives proposed were direct election of the mayor by the people or appointment by the city council (gemeenteraad). A constitutional change to allow for this failed to pass the Senate in March 2005.
Nepal
Mayors in Nepal are elected every Five years in the Local elections.

New Zealand

Mayors in New Zealand are elected every three years in the local body elections.
Pakistan
In Pakistan, a city is headed by the District Nazim (the word means "supervisor" in Urdu, but is sometimes translated as Mayor) and assisted by Naib Nazim who is also speaker of District Council. District Nazim is elected by the nazims of union councils, union councillors and by tehsil nazims, who themselves are elected directly by the votes of the local public. Council elections are held every four years.
Philippines
In the Philippines, mayors (Tagalog: Punong Bayan / Punong Lungsod) are the head of a municipality or a city, with the vice mayor as the second highest position in the city. They are elected every three years during the midterm and national elections, and they can serve until three terms of office. As of - September 2012, there are 1,635 mayors in the Philippines.
Poland
Mayors in Poland are directly elected by inhabitants of their respective municipality. The mayor is the sole chief of the executive branch of the municipality and he cannot serve on the municipal council (city council) or in the parliament. The mayor may appoint a deputy mayor if needed. In Poland, a mayor is called a burmistrz or, in towns with more than 100,000 inhabitants or other municipalities that traditionally use the title, prezydent ("president", for example "President of Warsaw", instead of "Mayor of Warsaw"). The equivalent title in a rural community ("gmina") is "wójt".
The mayor is elected for a four-year term concurrently with the four-year term of the municipal council, and his/her service is terminated at the end of the municipal council's term. Mayors cannot be dismissed by the municipal council, but they can be removed from the office by the citizens of their municipality in a referendum. A mayor can also be dismissed by the Prime Minister in case of persistent transgression of the law. Citizens having a criminal record cannot run for mayor, but only if sentenced for intentional offense ex officio.
The mayor manages the municipal estate, issues minor regulations, and incurs liabilities within limits set by the municipal council. The mayor presents a budget to the municipal council, that may then be amended by the council. After the municipal council passes the budget in a form of resolution, the mayor is responsible for its realization. The mayor is the head of the town hall and the register office (he/she may appoint deputies for these specific tasks). Mayors legally act as employers for all of the officials of the town hall. Mayors in Poland have wide administrative authority: the only official that he/she cannot appoint or dismiss is a city treasurer, who is appointed by a city council. Although mayors in Poland do not have veto power over city council resolutions, their position is relatively strong and should be classified as a mayor-council government.
Portugal
In Portugal and many other Portuguese-speaking countries the mayor of a municipality is called the Presidente da Câmara Municipal (President of the Municipal Chamber).
Romania
In Romania the mayor of a commune, town or city is called primar. He is elected for a period of four years. In carrying out his responsibilities he is assisted by an elected local council (consiliu local). Bucharest has a general mayor (primar general) and six sector mayors (primar de sector), one for each sector. The responsibilities of the mayor and of the local council are defined by Law 215/2001 of the Romanian Parliament.[8]
Russia
In Russia, the Мэр, from fr Maire (en transcription = Mer - not to be confused to the NATO OF-3 rank Майор - en: Major), is one of possible titles of the head of the administration of a city or municipality.  This title is equivalent to that of the head of a Russian rural district. Exceptionally, the mer of Moscow, Saint-Petersburg and Sevastopol are equivalent to governors in Russia, since these three federal cities are equivalent to Russian federations.
Except for those just-named three large cities, the governance system of a Russian municipality (city, county, district or town) is subordinate to the representative council of the federation in which it is located. The mer, is either directly elected in municipal elections (citywide referendum) or is elected by the members of the municipality's representative council. Election by council members is now more widespread because it better integrates with the Russian federal three-level vertical governance structure:
National government: 
President (executive)
Federal Assembly
Federation governments: 
Heads of federation (commonly governors)
Regional representative councils
Local governments: 
Heads of administration (who have the official title of mer, whether or not local law defines it as such)
Local representative councils
The typical term of office of a mer in Russia is four years. The mer's office administers all municipal services, public property, police and fire protection, and most public agencies, and enforces all local and state laws within a city or town.
According to Medialogy,[9] the mer of Novosibirsk, Edward Lokot', is mentioned in the media more than any other Russian mayor.  The mer of Kazan, Il'sur Metshin, is the most popular in Russia, scoring 76 out of 100, according to the Russian People's Rating of Mers.[10]
Serbia
In Serbia, the mayor is the head of the city or a town. He acts on behalf of the city, and performs an executive function. The position of the mayor of Belgrade is important as the capital city is the most important hub of economics, culture and science in Serbia. Furthermore, the post of the mayor of Belgrade is the third most important position in the government after the Prime Minister and President.
Spain and Hispanic America
Alcalde is the most common Spanish term for the mayor of a town or city. It is derived from the Arabic: al-qaḍi (قاضي‎), i.e., "the (Sharia) judge," who often had administrative, as well as judicial, functions. Although the Castilian alcalde and the Andalusian qaḍi had slightly different attributes (the qaḍi oversaw an entire province, the alcalde only a municipality; the former was appointed by the ruler of the state but the latter was elected by the municipal council), the adoption of this term reflects how much Muslim society in the Iberian Peninsula influenced the Christian one in the early phases of the Reconquista. As Spanish Christians took over an increasing part of the Peninsula, they adapted the Muslim systems and terminology for their own use.
Today, it refers to the executive head of a municipal or local government, who usually does not have judicial functions. The word intendente is used in Argentina and Paraguay for the office that is analogous to a mayor.
In larger cities in Mexico, the chief executive is known as the presidente municipal or "municipal president".
Sweden
The Swedish title borgmästare (burgomaster) was abolished in the court reform of 1971 when also the towns of Sweden were officially abolished. Since the middle of the 20th century, the municipal commissioner – the highest-ranking politician in each municipality – is informally titled "mayor" in English.
Switzerland
The function and title for mayor vary from one canton to another. Generally, the mayor presides an executive council of several members governing a municipality.
The title is:
in Italian: Sindaco (Ticino), Podestà (Grigioni)
in French: Maire (Geneva, Jura, Bern), Syndic (Vaud, Fribourg),  Président du Conseil municipal (Valais), Président du Conseil communal (Neuchâtel)
in German: e.g. Stadtpräsident, Stadtammann, Gemeindepräsident, Gemeindeammann
Taiwan
In the Republic of China in Taiwan the mayor is the head of city's government and its city's council, which is in charge of legislative affairs. The mayor and city council are elected separately by the city's residents.
Turkey
Mayors (Turkish:Belediye Başkanı) in Turkey are elected by the municipal councill. As a rule, there are municipalities in all province centers and district centers as well as towns (Turkish: belde) which are actually villages with a population in excess of 2000. However beginning by 1983, a new level of municipality is introduced in Turkish administrative system. In big cities Metropolitan municipalities (Turkish: Büyükşehir belediyesi) are established. (See Metropolitan municipalities in Turkey) In a Metropolitan municipality there may be several  district municipalities (hence mayors).
Ukraine
In Ukraine the title Mer was introduced for the position of the head of the municipal state administration in the federal cities of Kiev and Sevastopol. In the rest of the urban and rural settlements the position is unofficial and simply refers to the head of a local council who at the moment of such assignment cannot be affiliated with any party of the council.
United States

The mayor is the leader in most United States municipalities (such as cities, townships, etc.). In the United States, there are several distinct types of mayors, depending on the system of local government. Under council-manager government, the mayor is a first among equals on the city council, which acts as a legislative body while executive functions are performed by the appointed manager. The mayor may chair the city council, but lacks any special legislative powers. The mayor and city council serve part-time, with day-to-day administration in the hands of a professional city manager. The system is most common among medium-sized cities from around 25,000 to several hundred thousand, usually rural and suburban municipalities.
In the second form, known as mayor-council government, the mayoralty and city council are separate offices. Under a strong mayor system, the mayor acts as an elected executive with the city council exercising legislative powers. They may select a chief administrative officer to oversee the different departments. This is the system used in most of the United States' large cities, primarily because mayors serve full-time and have a wide range of services that they oversee. In a weak mayor or ceremonial mayor system, the mayor has appointing power for department heads but is subject to checks by the city council, sharing both executive and legislative duties with the council. This is common for smaller cities, especially in New England. Charlotte, North Carolina and Minneapolis, Minnesota are two notable large cities with a ceremonial mayor.
Many American mayors are styled "His Honor" or "Her Honor" while in office.
Multi-tier local government
In several countries, where there is not local autonomy, mayors are often appointed by some branch of the federal or regional government. In some cities, subdivisions such as boroughs may have their own mayors; this is the case, for example, with the arrondissements of Paris, Montreal, and Mexico City. In Belgium, the capital, Brussels, is administratively one of the federation's three regions, and is the only city subdivided, without the other regions' provincial level, into 19 rather small municipalities, which each have an elected—formally appointed—Burgomaster (i.e., Mayor, responsible to his / her elected council); while Antwerp, the other major metropolitan area, has one large city (where the boroughs, former municipalities merged into it, elect a lower level, albeit with very limited competence) and several smaller surrounding municipalities, each under a normal Burgomaster as in Brussels.
In the People's Republic of China, the Mayor (市長) may be the administrative head of any municipality, provincial, prefecture-level, or county-level. The Mayor is usually the most recognized official in cities, although the position is the second-highest-ranking official in charge after the local Communist Party Secretary. In principle, the Mayor (who also serves as the Deputy Communist Party Secretary of the city) is responsible for managing the city administration while the Communist Party Secretary is responsible for general policy and managing the party bureaucracy, but in practice the roles blur, frequently causing conflict.
Acting mayor
Acting mayor is a temporary office created by the charter of some municipal governments.
In many cities and towns, the charter or some similar fundamental document provides that in the event of the death, illness, resignation, or removal from office of the incumbent mayor, another official will lead the municipality for a temporary period, which, depending on the jurisdiction, may be for a stated period of days or months until a special election can be held, or until the original end of the term to which the vacating mayor was elected.
Some cities may also provide for a deputy mayor to be temporarily designated as "acting mayor" in the event that the incumbent mayor is temporarily unavailable, such as for health reasons or out-of-town travel, but still continues to hold the position and is expected to return to the duties of the office. In this latter capacity, the acting mayor's role is to ensure that city government business can continue in the regular mayor's absence, and the acting mayor is not deemed to have actually held the office of mayor.
The position of acting mayor is usually of considerably more importance in a mayor-council form of municipal government, where the mayor performs functions of day-to-day leadership, than it is in a council-manager form of government, where the city manager provides day-to-day leadership and the position of mayor is either a largely or entirely ceremonial one.
In some jurisdictions, the mayor's successor is not considered to be an acting mayor but rather fully mayor in his or her own right, much in the manner that the Vice President of the United States is not styled or considered to be Acting President following the death or resignation of the President, but rather President in every sense.
