Berlin (; German: [bɛʁˈliːn] (listen)) is the capital and biggest city of Germany by both area and population. Its 3,769,495 inhabitants as of 31 December 2019 make it the most populous city of the European Union, according to population within city limits. The city is also one of Germany's 16 federal states. It is surrounded by the state of Brandenburg, and contiguous with Potsdam, Brandenburg's capital. The two cities are at the middle of the Berlin-Brandenburg capital region, which is, with about six million inhabitants and an area of over 30,000 km2, Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main areas. Berlin straddles the banks of the River Spree, which flows to the River Havel (a tributary of the River Elbe) from the western borough of Spandau. Among the city's main topographical features are the numerous lakes in the western and southeastern boroughs formed by the Spree, Havel, and Dahme rivers (the biggest of which is Lake Müggelsee). Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. About one-third of the city's area is composed of woods, parks, gardens, rivers, canals and lakes. The city lies in the Central German dialect region, the Berlin dialect being a version of the Lusatian-New Marchian dialects. First documented in the 13th century and situated at the crossing of two important historic trade routes, Berlin became the capital of the Margraviate of Brandenburg (1417--1701), the Kingdom of Prussia (1701--1918), the German Empire (1871--1918), the Weimar Republic (1919--1933), and the Third Reich (1933--1945). Berlin in the 1920s was the third-largest municipality in the world. Following World War II and its subsequent occupation by the victorious nations, the city was divided; West Berlin became a de facto West German exclave, surrounded by the Berlin Wall (1961--1989) and East German territory. East Berlin was declared capital of East Germany, while Bonn became the West German capital. Following German reunification in 1990, Berlin once again became the capital of all of Germany. Berlin is a world city of culture, politics, media and science.

With the world's oldest large-scale film studio complex, Berlin is an increasingly popular location for international film productions.

Philadelphia, colloquially Philly, is the largest city in the U.S. state of Pennsylvania and the sixth-most populous U.S. city, with a 2019 estimated population of 1,584,064. Since 1854, the city has had the same geographic boundaries as Philadelphia County, the most-populous county in Pennsylvania and the urban core of the eighth-largest U.S. metropolitan statistical area, with over 6 million residents as of 2017. Philadelphia is also the economic and cultural center of the greater Delaware Valley along the lower Delaware and Schuylkill rivers within the Northeast megalopolis.

William Penn, an English Quaker, founded the city in 1682 to serve as capital of the Pennsylvania Colony. Philadelphia played an instrumental role in the American Revolution as a meeting place for the Founding Fathers of the United States, who signed the Declaration of Independence in 1776 at the Second Continental Congress, and the Constitution at the Philadelphia Convention of 1787. Several other key events occurred in Philadelphia during the Revolutionary War including the First Continental Congress, the preservation of the Liberty Bell, the Battle of Germantown, and the Siege of Fort Mifflin. Philadelphia remained the nation's largest city until being overtaken by New York City in 1790; the city was also one of the nation's capitals during the revolution, serving as temporary U.S. capital while Washington, D.C. was under construction. In the 19th and 20th centuries, Philadelphia became a major industrial center and a railroad hub. The city grew due to an influx of European immigrants, most of whom initially came from Ireland and Germany—the two largest reported ancestry groups in the city as of 2015.
