The Anglo-Saxons were a cultural group who inhabited England in the Early Middle Ages. They traced their origins to the 5th century settlement of incomers to Britain, who migrated to the island from the North Sea coastlands of mainland Europe. Some sources say that the Saxon warriors were invited to come, to the area now know as England, to help keep out invaders from Scotland and Ireland. Another reason for coming may have been because their land often flooded and it was difficult to grow crops, so they were looking for new places to settle down and farm.
