Over 500,000 Years of History

The island of Great Britain has been inhabited by early humans for at least 500,000 years. It is believed that these humans crossed a land bridge from continental Europe at that time. Modern humans have been in Great Britain for about 30,000 years and until about 12,000 years ago, archeological evidence shows that they moved back and forth between the island and continental Europe via a land bridge. This land bridge closed and Great Britain became an island at the end of the last glaciation.

Throughout the decades following the Norman Conquest, Great Britain was ruled by several different kings and queens and it was also part of several different treaties between the countries on the island.
