About “De excidio et conquestu Britanniæ ac flebili castigatione in reges, principes et sacerdotes”
De Excidio et Conquestu Britanniae is a Latin sermon written in the late fifth or sixth century by Gildas, a British religious polemicist. The work is divided into three parts and serves as a critique of the actions of Gildas' contemporaries, both secular and religious, whom he blames for the troubled state of sub-Roman Britain. Historians agree that the text is not a straightforward historical account and cannot be used to create a reliable narrative of fifth- and sixth-century Britain. However, it remains one of the most important sources for the period, as it is the only significant historical text written by someone who lived close to the events it describes.
