The Philadelphia area had been the location of the Lenape (Delaware) village Shackamaxon prior to the arrival of Europeans.

Fifty families on a ship captained by George Lamberton settle in 1642 at the mouth of Schuylkill River around to establish a trading post at what is today Philadelphia.

The Dutch and Swedes who are already in the area burn their buildings.

A court in New Sweden is to convict Lamberton of "trespassing, conspiring with the Indians."

The New Haven Colony gets no support from its New England patrons: Puritan Governor John Winthrop is to testify that the "Delaware Colony" "dissolved" owing to “summer sickness and mortality”.

While New Haven is to retreat from the venture, the Lenape agreement, which places no westward limit on the land west of the Delaware, is to be the legal basis for a Connecticut "sea to sea" claim of owning all the land on both sides of the Delaware from the Atlantic Ocean to the Pacific Ocean.
