Jewish traders were operating in southeastern Pennsylvania long before William Penn. Furthermore, Jews in Philadelphia took a prominent part in the War of Independence. Although the majority of the early Jewish residents were of Portuguese or Spanish descent, some among them had emigrated from Germany and Poland. About the beginning of the 19th century, a number of Jews from the latter countries, finding the services of the Congregation Mickvé Israel unfamiliar to them, resolved to form a new congregation which would use the ritual to which they had been accustomed.
With immigration from the Middle East, the Horn of Africa, Pakistan, Bangladesh and India, Islam has seen a huge growth in Philadelphia.
