In 1682, William Penn founded the city 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 and the Constitution in 1787. Philadelphia was one of the nation's capitals in the Revolutionary War, and served as temporary U.S. capital while Washington, D.C., was under construction. In the 19th century, Philadelphia became a major industrial center and railroad hub that grew from an influx of European immigrants. It became a prime destination for African-Americans in the Great Migration and surpassed two million occupants by 1950.

The Armenians collective has, at times, constituted a Christian "island" in a mostly Muslim region. There is, however, a minority of ethnic Armenian Muslims, known as Hamshenis but many Armenians view them as a separate race, while the history of the Jews in Armenia dates back 2,000 years. The Armenian Kingdom of Cilicia had close ties to European Crusader States. Later on, the deteriorating situation in the region led the bishops of Armenia to elect a Catholicos in Etchmiadzin, the original seat of the Catholicosate. In 1441, a new Catholicos was elected in Etchmiadzin in the person of Kirakos Virapetsi, while Krikor Moussapegiants preserved his title as Catholicos of Cilicia. Therefore, since 1441, there have been two Catholicosates in the Armenian Church with equal rights and privileges, and with their respective jurisdictions. The primacy of honor of the Catholicosate of Etchmiadzin has always been recognized by the Catholicosate of Cilicia.

Until the death of Sigismund II Augustus, the last king of the Jagiellonian dynasty, monarchs could be elected from within only the royal family. However, starting from 1573, practically any Polish noble or foreigner of royal blood could become a Polish–Lithuanian monarch. Every newly elected king was supposed to sign two documents—the Pacta conventa ("agreed pacts")—a confirmation of the king's pre-election promises, and Henrican articles (artykuły henrykowskie, named after the first freely elected king, Henry of Valois). The latter document served as a virtual Polish constitution and contained the basic laws of the Commonwealth:
