The Anglo-Saxon Chronicle is a collection of annals that chronicles the history of the Anglo-Saxons in England. Compiled in the late 9th century, it provides a year-by-year account of significant events, including battles, royal reigns, and cultural developments. The Chronicle was originally commissioned by King Alfred the Great to preserve the history and achievements of the Anglo-Saxon people. Written in Old English, the Chronicle exists in several versions, with the most notable being the Winchester and Peterborough manuscripts. It serves as a vital historical source, offering insights into the social, political, and religious life of early medieval England, and is crucial for understanding the period leading up to the Norman Conquest in 1066.
