What refers to Germanic tribes who migrated Britain and developed a unique culture language there?

The Germanic tribes who migrated to Britain and developed a unique culture and language there are collectively referred to as Anglo-Saxons.

Here's a breakdown:

* Angles: A Germanic tribe who came from the area of modern-day Denmark.

* Saxons: Another Germanic tribe who came from the area of modern-day northern Germany and the Netherlands.

* Jutes: A smaller tribe from the area of modern-day Jutland (Denmark).

These tribes invaded and conquered parts of Britain during the 5th and 6th centuries, following the decline of Roman rule. They established kingdoms, introduced their languages, and contributed to the development of Anglo-Saxon culture, which included art, literature, and law. This period is often referred to as the Anglo-Saxon period in British history.

The language spoken by the Anglo-Saxons, Old English, is the direct ancestor of modern English. It evolved and changed over time, eventually becoming Middle English and then Modern English.
