After the Romans left Britain in the 5th century, various kingdoms emerged across the island including Sussex, Wessex, and Essex. In the 9th century, England was overrun by Danish Vikings. Maps from the 14th century show Britain divided into four parts: England, Scotland, Wales, and Cornwall. Cornwall saw rebellions in the 16th century during the Anglo-Spanish War and the English Civil War in the 1640s as it sought more autonomy. Famous Cornish locations include St. Michael's Mount, the Minack Theatre, Trebah Garden, and St. Ives, while notable people from Cornwall include scientists Humphry Davy and John Couch Adams.
