1641: Swedes and Finns spreading north from Fort Christina (present-day Wlimington, Delaware) first settle in Finland (Chamassungh), now Trainer, Pennsylvania  and Upland (Meckopenacka), now Chester, Pennsylvania. The New Sweden Colony continues to expand northward with new settlements as far as Philadelphia in the following years.

1651-1655: The New Netherland Colony builds Fort Casimir  (now New Castle, Delaware), settle Sandhook,   and abandon Fort Beversrede (now Philadelphia) in 1651. In 1654 New Sweden captures Fort Casimir from the Dutch without a fight and renames it Fort Trinty (Trefaldighets). In 1655 New Netherland returns with a large army and all of New Sweden in presend-day Pennsylvania, Delaware, and New Jersey submits to Dutch rule.

1664: As part of the Second Anglo-Dutch War New Netherland including southeast Pennsylvania is surrendered to the English.

1673-1674: A new war breaks out and the Dutch send a large armada to retake New Netherland for a few months. But as the war ends the colony is ceeded to England for the last time.

1680s: William Penn founded the English colony of Pennsylvania after receiving a grant in 1681 from the king of England. His colony offered religious freedom, liberal government, and inexpensive land. Quakers established the city of Philadelphia.
