The colony was founded in 1607 by a group of 120 English settlers led by George Popham and Raleigh Gilbert. The settlers were granted a charter by King James I to establish a colony in the region known as "Norumbega". The colony was named after Popham, who was the president of the Virginia Company of Plymouth, the organization that sponsored the expedition.
The settlers arrived in Maine in May 1607 and established a settlement on the banks of the Kennebec River. They built a fort, a storehouse, and a number of other buildings. However, the colony soon faced a number of challenges, including harsh weather, disease, and attacks by Native Americans.
In the fall of 1607, the settlers decided to abandon the colony and return to England. The Popham Colony was a failure, but it paved the way for future English settlements in North America.
