Answer :
The beginning of the Anglo-Saxon period roughly corresponds with the following historical events:
1. **The Fall of the Roman Empire**: The decline and eventual fall of the Western Roman Empire in the 5th century, particularly marked by the sack of Rome in 410 AD by the Visigoths and the deposition of the last Roman emperor, Romulus Augustulus, in 476 AD.
2. **The Arrival of the Anglo-Saxons in Britain**: The migration and settlement of Germanic tribes (mainly the Angles, Saxons, and Jutes) in Britain, which began in the mid-5th century. This period is often dated to around 449 AD, when, according to tradition, the first significant groups of Anglo-Saxons arrived in Britain, invited by the Britons to help defend against Pictish and Scottish invaders.
These events mark the transition from Roman Britain to the early medieval period, where the Anglo-Saxon culture began to emerge and dominate the landscape of what would eventually become England.
