Allegheny County, Pennsylvania

Allegheny County, Pennsylvania
Allegheny County is a county in Pennsylvania, United States. It is located in Southwestern Pennsylvania. As of the 2020 census, the population was 1,250,578, making it the state's second-most populous county, after Philadelphia County. Its county seat and most populous city is Pittsburgh, Pennsylvania's second most populous city.
Allegheny County is part of the Pittsburgh, PA metropolitan statistical area and the Pittsburgh media market.
Allegheny was the first county in Pennsylvania to be given a Native American name. It was named after the Lenape word for the Allegheny River. The meaning of "Allegheny" is uncertain. It is usually said to mean "fine river". Stewart says that the name may come from a Lenape account of an ancient mythical tribe called "Allegewi", who lived along the river before being taken over by the Lenape.
History
Prior to European contact, this area was settled for thousands of years by succeeding cultures of indigenous peoples. During the colonial era, historic native groups known by the colonists to settle in the area included members of western nations of the Iroquois, such as the Seneca; the Lenape, who had been pushed from the East by European-American settlers; the Shawnee, who also had territory in Ohio; and the Mingo, a group made up of a variety of peoples from more eastern tribes.
European fur traders such as Peter Chartier established trading posts in the region in the early eighteenth century.
In 1749, Captain Pierre Joseph Céloron de Blainville claimed the Ohio Valley and all of western Pennsylvania for King Louis XV of France. The captain traveled along the Ohio and Allegheny rivers. He installed lead plates in the ground to mark the land for France.
Most of the towns during that era were developed along waterways, which were the primary transportation routes, as well as providing water for domestic uses. Through the eighteenth century, both the French and the British competed for control over the local rivers in this frontier territory of North America. Native American bands and tribes allied with the colonists to differing degrees, often based on their trading relationships. The British sent Major George Washington to expel the French from their posts, with no success. He also nearly drowned in the ice-filled Allegheny River while returning to camp.
The English tried again in 1754 to establish a post in the area. They sent 41 Virginians to build Fort Prince George. The French learned of the plan and sent an army to capture the fort. They resumed building it and added increased defensive fortification, renaming it as Fort Duquesne.
Given its strategic location at the Ohio, Fort Duquesne became an important focal point of the French and Indian War. The first British attempt to retake the fort, the Braddock Expedition, failed miserably. In 1758 British forces under General John Forbes recaptured the fort; he had it destroyed to prevent any use by the French. The British built a new, larger fort on the site, including a moat, and named it Fort Pitt. The historic site has been preserved as Pittsburgh's Point State Park.
Under their colonial charters, both Pennsylvania and Virginia claimed the region that is now Allegheny County. Pennsylvania administered most of the region as part of its Westmoreland County. Virginia considered everything south of the Ohio River and east of the Allegheny River to be part of its Yohogania County, and governed it from Fort Dunmore. In addition, parts of the county were located in the proposed British colony of Vandalia and the proposed U.S. state of Westsylvania. The overlapping boundaries, multiple governments, and confused deed claims soon proved unworkable. Near the end of the American Revolutionary War, in 1780 Pennsylvania and Virginia agreed to extend the Mason–Dixon line westward. This region was assigned to Pennsylvania. From 1781 until 1788, much of what Virginia had claimed as part of Yohogania County was administered as a part of the newly created Washington County, Pennsylvania.
Allegheny County was officially created on September 24, 1788, from parts of Washington and Westmoreland counties. It was formed to respond to pressure from the increase in settlers living in the area around Pittsburgh; this was designated as the county seat in 1791. The county originally extended north to the shores of Lake Erie; it was reduced to its current borders by 1800. As population increased in the territory, other counties were organized.
In the 1790s, the United States federal government imposed a whiskey excise tax. Farmers who had depended on whiskey income refused to pay and started the so-called Whiskey Rebellion after driving off tax collector John Neville. After a series of demonstrations by farmers, President George Washington sent troops to suppress the frontier rebellion.
The area developed rapidly through the 1800s with industrialization. It became the nation's prime steel producer by the late 19th century and Pittsburgh was nicknamed "Steel Capital of the World".
In 1913, the county's 125th anniversary was celebrated with a week-long series of events. The final day, September 27, was marked by a steamboat parade of 30 paddle wheelers. They traveled from Monongahela Wharf down the Ohio to the Davis Island Dam. The boats in line were the Steel City (formerly the Pittsburgh and Cincinnati packet Virginia), the flag ship; City of Parkersburg, Charles Brown, Alice Brown, Exporter, Sam Brown, Boaz, Raymond Horner, Swan, Sunshine, I. C. Woodward, Cruiser, Volunteer, A. R. Budd, J. C. Risher, Clyde, Rival, Voyager, Jim Brown, Rover, Charlie Clarke, Robt. J. Jenkins, Slipper, Bertha, Midland Sam Barnum, Cadet, Twilight, and Troubadour.
On October 27, 2018, during a Sabbath course and a Torah study a domestic terrorist attack occurred at the Tree of Life – Or L'Simcha Congregation killing 11 people and harming six others, marking it one of the deadliest terrorist attacks in Pennsylvania history.
Geography
According to the U.S. Census Bureau, the county has a total area of , of which is land and (1.9%) is water.
Three major rivers traverse Allegheny County: the Allegheny River and the Monongahela River converge at Downtown Pittsburgh to form the Ohio River. The Youghiogheny River flows into the Monongahela River at McKeesport, to the southeast. There are several islands in these courses. The rivers drain via the Mississippi River into the Gulf of Mexico. Although the county's industrial growth resulted in clearcutting of the area's forests at one time, there has been regrowth and a significant woodland remains.

Climate
Allegheny has a humid continental climate which is hot-summer, (Dfa) except in higher elevations, where it is warm-summer (Dfb).
Government and politics
Until January 1, 2000, Allegheny County's government was defined under Pennsylvania's Second Class County Code. The county government was charged with all local activities, including elections, prisons, airports, public health, and city planning. All public offices were headed by elected citizens. There were three elected county commissioners.
On January 1, 2000, the Home-Rule Charter went into effect. It replaced the three elected commissioners with an elected chief officer (the County Executive), a county council with 15 members (13 elected by district, two elected county-wide), and an appointed county manager. The changes were intended to maintain a separation of powers between the executive and legislative branches while providing greater citizen control.
The county has 130 self-governing municipalities, the most in the state. (Luzerne is second with 76). The county has one Second Class City (Pittsburgh) and three Third Class Cities (Clairton, Duquesne, and McKeesport).
A 2004 study found the county would be better served by consolidating the southeastern portion of the county (which includes many small communities with modest economies) into a large municipality ("Rivers City") with a combined population of approximately 250,000.
Government structure
Allegheny County has a Home Rule Charter form of government since 2000. The county has three branches: the executive, the legislative, and the judicial. The executive branch consists of the County Executive, who is elected for a four-year term and serves as the chief executive officer of the county; and the County Manager, who is appointed by the County Executive and oversees the daily operations of the county departments. The current County Executive is Rich Fitzgerald, a Democrat who took office in 2012 and was re-elected in 2016 and 2020. The current County Manager is William D. McKain, who was appointed by Fitzgerald in 2012 and reappointed in 2016 and 2020. The legislative branch consists of the County Council, which is composed of 15 members elected for four-year terms from single-member districts. The council functions as the primary legislative and policy-making body of the county. The current County Council President is Patrick Catena, a Democrat who represents District 4 and was elected by his fellow council members in 2018 and 2020. The judicial branch consists of the Court of Common Pleas, which is the general trial court of the county; and the Magisterial District Courts, which are lower courts that handle minor criminal and civil cases. The judges of these courts are elected for ten-year terms.The current President Judge of the Court of Common Pleas is Kimberly Berkeley Clark, who was elected by her fellow judges in 2018 for a five-year term.
Self-governing municipalities
Allegheny County has 130 self-governing municipalities, the most in the state. These include one city (Pittsburgh), 96 boroughs, 30 townships, two home rule municipalities (Bethel Park and McCandless), and one town (Bloomsburg).
Each municipality has its own elected officials, such as mayor, council, commissioners, supervisors, etc., and its own local services, such as police, fire, public works, etc.
Some municipalities also have their own municipal authorities that provide services such as water, sewer, transit, etc.
Changes to Administrative Divisions
There have been several proposals to consolidate or merge some of the municipalities in Allegheny County, either with each other or with the City of Pittsburgh, to reduce costs, improve efficiency, and enhance regional cooperation. However, none of these proposals have been implemented so far. One of the most recent proposals is from Wilkinsburg, a borough that borders Pittsburgh and faces financial challenges due to declining population and tax base. In 2020, Wilkinsburg residents voted to approve a referendum to explore a merger with Pittsburgh. In 2021, a joint task force was formed to study the feasibility and impact of such a merger. The task force is expected to issue a report by June 2022. If both Wilkinsburg and Pittsburgh councils approve the merger, it would then need approval from the state legislature and governor before taking effect. Another recent proposal is from Allegheny County Economic Development (ACED), which is seeking to enter into an agreement with a consultant to carry out historic preservation compliance activities for projects funded by various federal programs. The consultant would help ACED develop a Programmatic Memorandum of Agreement (PMOA) with the Pennsylvania State Historic Preservation Office (SHPO) and other stakeholders to streamline the review process for projects that may affect historic properties within the county. ACED issued a Request for Proposals (RFP) for this service in January 2022 and expects to select a consultant by March 2022.

Political history
The Republican Party had been historically dominant in county-level politics in the 19th and early 20th centuries; prior to the Great Depression, Pittsburgh and Allegheny County had been majority Republican. Since the Great Depression on the state and national levels, the Democratic Party has been dominant in county-level politics. It is by far the most Democratic county in western Pennsylvania. For much of the time between the Great Depression and the turn of the millennium, it was the second-strongest Democratic bastion in Pennsylvania, behind only Philadelphia.
In 2000, Democrat Al Gore won 56% of the vote and Republican George W. Bush won 41%. In 2004, Democrat John Kerry received 57% of the vote and Republican Bush received 41%. In 2006, Democrats Governor Ed Rendell and Senator Bob Casey Jr. won 59% and 65% of the vote in Allegheny County, respectively. In 2008, Democrat Barack Obama received 57% of the vote, Republican John McCain received 41%, and each of the three state row office winners (Rob McCord for Treasurer, Jack Wagner for Auditor General, and Tom Corbett for Attorney General) also carried Allegheny. In 2016, despite Donald Trump being the first Republican to carry Pennsylvania since 1988, Hillary Clinton did slightly better than Barack Obama's 2012 vote total while Donald Trump was the worst performing Republican in 20 years. In the 2018 Midterms, Democrats received an even higher percentage of the vote with Tom Wolf and Casey receiving approximately two thirds of the county's vote. This is an improvement over the approximately 55% each person received in the county in their last election in 2014 and 2012 respectively. In 2020, Joe Biden improved upon Clinton's performance, receiving the highest vote percentage for a Democrat since Michael Dukakis in 1988 and the most votes for a Democrat since Lyndon B. Johnson in 1964.

Economy
In the late 18th century, farming played a critical role in the growth of the area. There was a surplus of grain due to transportation difficulties in linking with the eastern portion of the state. As a result, the farmers distilled the grain into whiskey, which significantly helped the farmers financially.
The area quickly became a key manufacturing area in the young nation. Coupled with deposits of iron and coal, and the easy access to waterways for barge traffic, the city quickly became one of the most important steel producing areas in the world. Based on 2007 data from the US Army Corps of Engineers, Pittsburgh is the second (after Laredo, Texas) busiest inland port in the nation.
US steel production declined late in the 20th century, and Allegheny County's economy began a shift to other industries. It is presently known for its hospitals, universities, and industrial centers. Despite the decline of heavy industry, Pittsburgh is home to a number of major companies and is ranked in the top ten among US cities hosting headquarters of Fortune 500 corporations, including U.S. Steel Corporation, PNC Financial Services Group, PPG Industries, and H. J. Heinz Company.
The county leads the state in number of defense contractors supplying the U.S. military.

Allentown Borough – now the neighborhood of Allentown in Pittsburgh.
Birmingham Borough – what is now Pittsburgh's South Side.
Brushton Borough
Carrick Borough – now the neighborhood of Carrick. Formed out of Baldwin Township in 1904, this borough existed until it was annexed by Pittsburgh in 1927. It was named for Carrick-on-Suir, Ireland. Some of the area's manhole covers still bear the Carrick Borough name.
Chartier Township – existed at the time of the 1860 U.S. Federal Census.
Collins Township – in what is now the northeast part of the City of Pittsburgh, east of Lawrenceville and north of Penn Avenue.
Knoxville Borough
