Old English literature refers to the language and writings of Anglo-Saxon England between the 5th and 12th centuries. It was first an oral tradition but later developed a written form using manuscripts. The literature reflected the strong religious faith and admiration for heroic warriors of Anglo-Saxon culture at the time. Popular genres included poetry which was the dominant form, using unique literary devices like caesura and alliteration. Old English was influenced by the Germanic languages of invading populations like the Angles, Saxons, and Jutes, as well as Latin and Old Norse from the Vikings, and provides insight into early English history.
