In 1585 the British began the colony of Roanoke, and later Jamestown. These colonies grew in size, and were known as the Virginia Colony. English fur traders traded and established outposts in Virginia, and scouts were sent to these outposts to map the land. The Dutch established New Amsterdam on OTL Delaware Bay. The Dutch settlements were seized by the British during the Third and Fourth Colonial Wars and the area was renamed New York. In 1640 the Third Colonial War ended and the Ohio River Valley was occupied by the British, and the colony of Ohio was established. In 1550 the Welsh settlement of Madocia was established, and was taken from the Welsh by the British during the Third Colonial War. The area was renamed Charlestown, and became Charlestown Colony.
