Old English literature developed between 500-1100 AD. The Germanic tribes who invaded Britain in the 5th-6th centuries brought their language and traditions. The conversion to Christianity began in the late 6th century led by St. Augustine of Canterbury. Bede's Ecclesiastical History of the English People, completed in 731, was influential. Old English works were written in Latin until Alfred the Great revived English learning in the 9th century. Significant Old English works that survive include heroic poems like Beowulf and The Battle of Maldon, as well as biblical poems and The Dream of the Rood.
