Gildas

Gildas was a 6th-century British monk and historian, known for his writings that provide insight into early medieval Britain. His primary work, "On the Ruin and Conquest of Britain," offers a unique perspective on the social and political circumstances of post-Roman Britain, particularly the decline of Roman influence and the rise of local kingdoms. Gildas is notable for his moral critiques of contemporary leaders and the effects of conflict and invasion on society. His accounts are among the few surviving records of that era, making him a crucial source for understanding Britain's early history.
