The Angles, Saxons, and Jutes invaded Britain after the Romans left, as the country had no defense. They initially raided and plundered Britain but eventually decided to conquer and settle the land. Their settlement was violent, as they destroyed cities and killed priests. The Angles, Saxons, and Jutes established kingdoms in Britain organized around a king, councilors, nobles, free peasants, and slaves. Their language became the basis for modern English.
