Which group invaded England in 1066 AD?

The Normans were the group that invaded England in 1066 AD, a pivotal year in English history due to the Battle of Hastings. This event marked the beginning of Norman rule in England, following the successful invasion led by William the Conqueror. The Normans, originally from Scandinavia, had settled in what is now France and became known as the Normans or "Northmen." Their conquest brought significant changes to England's social structure, language, governance, and culture, shaping the future of the nation.

The other groups mentioned had varying roles in English history prior to 1066. The Anglo-Saxons had settled in England before this time and were the dominant culture until the Norman invasion. The Romans also played a crucial role earlier, having invaded and established control over Britain from AD 43 until around AD 410. The Danes, or Vikings, had performed raids and established settlements in England, particularly in the late 8th and early 9th centuries, but they did not execute a successful full-scale invasion like the Normans did in 1066. Thus, the Normans' invasion stands out as a defining moment that changed the course of English history.
