Historia Langobardorum (History of the Langobards), written by 8th-century monk Paul the Deacon, is a foundational six-volume account of the Germanic Lombard people. It chronicles their origins in Scandinavia, migration, 6th-century conquest of Italy, and history up to 743 AD, focusing on wars, kings, and cultural shifts from a pro-Lombard perspective. The book is an essential, albeit incomplete, source for understanding the migration period and the early medieval history of Italy.
