Originally, two English joint-stock companies had been created to settle North America, then known as the Colony of Virginia. In June 1606, the London Company was granted a charter for a section of the continent south of that given to the Plymouth Company. Both companies established settlements in 1607 - the London Company in Jamestown, and the Plymouth Company in Plymouth. Soon, the term Virginia came to refer only to that part of North America covered by the London Company's original charters. The third charter, of 1612, extended its territory far enough across the Atlantic to include the Somers Isles (Bermuda), which the Virginia Company had been in unofficial possession of since the 1609 wreck of the Sea Venture.
