The
history of Pennsylvania as a political entity began in 1681 when
William Penn received a royal charter from
King Charles II of England, but human activity in the region precedes that date. Before
Pennsylvania was settled by Europeans, the area was home to the
Lenape,
Susquehannock,
Iroquois,
Erie,
Shawnee and other
Native American tribes. Most of these tribes were driven off or reduced to remnants as a result of new diseases such as smallpox that arrived long before any permanent colonists. Pennsylvania was first colonized by Swedish and Dutch settlers in the 17th century, before the English took control of the colony in 1667. In 1681,
William Penn established a colony based on religious tolerance; it and its chief city, Philadelphia (the first planned city), was settled by many
Quakers. In the mid-eighteenth century, the colony attracted many German and
Scots-Irish immigrants
