Burd-Shippen papers 1738-1847
John Smith made the first documented voyage by Europeans to what is now the states of Pennsylvania and Delaware in 1608, followed shortly thereafter by Henry Hudson (1609) and Samuel Argall (1610). Between 1637 and 1638, Swedish immigrants began the first permanent European settlements in the area, though the territory often oscillated between Dutch and English control. In 1681, King Charles II of Great Britain granted William Penn a charter to land in the area; Penn established a colony, now named Pennsylvania, with a high tolerance of religious freedom, a large Quaker presence, and a certain degree of autonomy from English governance. During this period, the colony's largest migratory populations originated from Germany and the British Isles, with significant numbers of Scotch-Irish. Pennsylvania outlawed slavery in 1780. Philadelphia was the site of the signing of the Declaration of Independence and the capital of the United States throughout the American Revolution. During the early stages of the Industrial Revolution, Pennsylvania's main industries centered on iron and steel, with a significant printing industry based around Philadelphia. Notably, the Erie Canal, finished in 1825, allowed transport from the Great Lakes to the Atlantic Ocean.
