Final answer:
The initial land of Delaware was under Dutch and then Swedish control. The first charter as part of an English colony, however, was granted by King Charles II to Quaker William Penn in 1681, making Pennsylvania and Delaware one entity under his leadership.
Step-by-step explanation:
The first charter for the colony of Delaware was not granted in 1637 specifically; the land that would become Delaware was under Dutch control initially and then Swedish. It was later, in 1681, that King Charles II of England ultimately granted the land to Quaker William Penn, which included what is now Pennsylvania and Delaware. Although initially the region was ruled technically by the governor of New York, in 1682, the Duke of York ceded the territory known as the "Territories" or "Lower Counties" (Delaware) to William Penn. This was done under a land patent that did not expressly grant Penn the right to govern the territory, but he incorporated Delaware with Pennsylvania anyway. The colonies shared a governor and had a degree of self-governance that included religious tolerance and a liberal government structure.
