What tribes attacked Britain in the 5th century?

In the 5th century, Britain faced invasions primarily from several Germanic tribes, including the Angles, Saxons, and Jutes. These groups began to settle in Britain following the decline of Roman authority, leading to significant cultural and political changes. Their incursions contributed to the fragmentation of Roman Britain and the eventual establishment of various kingdoms in the region. The invasions marked the beginning of what is often referred to as the Anglo-Saxon period in British history.
