It is bordered to the northwest by Armenia, the "de facto" Nagorno-Karabakh Republic, and Azerbaijan; to the north by the Caspian Sea; to the northeast by Turkmenistan; to the east by Afghanistan and Pakistan; to the south by the Persian Gulf and the Gulf of Oman; and to the west by Turkey and Iraq. Comprising a land area of , it is the second-largest country in the Middle East and the 18th-largest in the world. With 82.8 million inhabitants, Iran is the world's 17th-most-populous country. It is the only country with both a Caspian Sea and an Indian Ocean coastline. The country's central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, make it of great geostrategic importance. Tehran is the country's capital and largest city, as well as its leading economic center., The Constitution of the Islamic Republic of Iran was adopted by referendum on 2 and 3 December 1979, and went into force replacing the Constitution of 1905. It was amended on 28 July 1989. The constitution has been called a "hybrid" of "theocratic and democratic elements". While articles One and Two vest sovereignty in God, article six "mandates popular elections for the presidency and the Majlis, or parliament." However all democratic procedures and rights are subordinate to the Guardian Council and the Supreme Leader, whose powers are spelled out in Chapter Eight (Articles 107-112)., Sayyed Ali Hosseini Khamenei (; 19 April 1939) is the second and current Supreme Leader of Iran and a Muslim cleric. Ali Khamenei succeeded Ruhollah Khomeini, the leader of the Iranian Revolution, after Khomeini's death, being elected as the new Supreme Leader by the Assembly of Experts on 4 June 1989, at age 49. Current Iranian president Hassan Rouhani arranged for Khamenei to get his first major post in the provisional revolutionary government as deputy defense minister. Khamenei also served as the President of Iran from 1981 to 1989. In 2012, 2013, and 2014 "Forbes" selected him 21st, 23rd, and 19th, respectively, in the list of "The World's Most Powerful People"., The Guardian Council of the Constitution ("Shora-ye Negahban-e Qanun-e Assassi") is an appointed and constitutionally-mandated 12-member council that wields considerable power and influence in the Islamic Republic of Iran., Ayatollah (or ; from "Sign of Allah") is a high-ranking title given to Usuli Twelver Shah clerics. Those who carry the title are experts in Islamic studies such as jurisprudence, quran reading, and philosophy and usually teach in Islamic seminaries. The next lower clerical rank is Hujjat al-Islam., The Expediency Discernment Council of the System ("Majma' Tašxis Malahat Nezâm") is an administrative assembly appointed by the Supreme Leader and was created upon the revision to the Constitution of the Islamic Republic of Iran on 6 February 1988. It was originally set up to resolve differences or conflicts between the Majlis and the Guardian Council, but "its true power lies more in its advisory role to the Supreme Leader." According to Hooman Majd, the Leader "delegated some of his own authority to the council  granting it supervisory powers over all branches of the government"  following President Mahmoud Ahmadinejad's election in 2005., Tehran ( "Tehrn") is the capital of Iran and Tehran Province. With a population of around 9 million in the city and 16 million in the wider metropolitan area, Tehran is the most populous city of Iran, the 2nd-most populous city in Western Asia and the 3rd-largest metropolitan area in the Middle East. It is ranked 29th in the world by the population of its metropolitan area., Grand Ayatollah Ahmad Azari-Qomi-Bigdeli (19251999) was an Iranian cleric., Ayatollah Reza Ostadi Moghadam ( Persian :    ) ( born 1937 in Tehran ) is a member of the Expediency Discernment Council and the Assembly of Experts of the Islamic Republic of Iran . Previously , during the presidency of Mohammad Khatami , he was also a member of the Guardian Council . While in the Guardian Council in 2000 , he confirmed the rejection of 600 candidates out of an original 758 candidates who were running for public office ., Twelver (Athn'ashariyyah or Ithn'ashariyyah ) Shia Islam or Imamiyyah is the largest branch of Shia Islam. Twelver belief is based on the Quran and the message of the Islamic Prophet Muhammad attested in hadith, and on hadith taught by their Imams. The term "Twelver" refers to its adherents' belief in twelve divinely ordained leaders, known as the Twelve Imams, and their belief that the last Imam, Muhammad al-Mahdi, lives in occultation and will reappear as the promised Mahdi. According to Shia tradition, the Mahdi's tenure will coincide with the Second Coming of Jesus Christ ("Isa"), who is to assist the "Mahdi" against the "Masih ad-Dajjal" (literally, the "false Messiah" or Antichrist)., The President of Iran ("") is the head of government of the Islamic Republic of Iran. The President is the highest popularly elected official in Iran, although the President answers to the Supreme Leader of Iran, who functions as the country's head of state. Chapter IX of the Constitution of the Islamic Republic of Iran sets forth the qualifications for presidential candidates and procedures for election, as well as the President's powers and responsibilities as "functions of the executive". These include signing treaties and other agreements with foreign countries and international organizations; administering national planning, budget, and state employment affairs; and appointing ministers subject to the approval of Parliament. However, in reality the president mainly gets the blame for failures than actually making the decisions. The current long-time Supreme Leader Ali Khamenei, who has been ruling for nearly three decades, has been issuing decrees and making the final decisions on economy, environment, foreign policy, national planning such as population growth, and everything else in Iran. Khamenei also makes the final decisions on the amount of transparency in elections in Iran, and has fired and reinstated Presidential cabinet appointments. , Seyyed Mohammad Khatami (; born 29 September 1943) is an Iranian scholar, Shia theologian, and reformist politician. He served as the fifth President of Iran from 3 August 1997 to 3 August 2005. He also served as Iran's Minister of Culture from 1982 to 1992.

Members of the assembly are elected from lists of candidates by direct public vote for eight-year terms. The number of members has ranged from 82 elected in 1982 to 88 elected in 2016. Current laws require the assembly to meet for at least two days every six months. The current chairman of the Fifth Assembly is Ahmad Jannati. All candidates to the Assembly of Experts, the President and the Majlis (Parliament), must be approved by the Guardian Council, while half of its members are selected by the Supreme Leader of Iran. Accordingly, the Assembly has never questioned the Supreme Leader. There have been instances when the current Supreme Leader Ali Khamenei publicly criticized members of the Assembly of Experts, resulting in their arrest and dismissal. For example, Supreme Leader Ali Khamenei publicly called then-member of the Assembly of Experts Ahmad Azari Qomi a traitor, resulting in Ahmad Azari Qomi's arrest and eventual dismissal from the Assembly of Experts., Ahmad Jannati is a hardline Iranian politician, Shi'i cleric and a founding member of Haghani school.
