Brie is a historic region of northern France notable in modern times for Brie cheese. It was once divided into three sections ruled by different feudal lords: the western Brie française, corresponding roughly to the modern department of Seine-et-Marne in the Île-de-France region; the eastern Brie champenoise, forming a portion of the modern department of Marne in the historic region of Champagne (part of modern-day Champagne-Ardenne); and the northern Brie pouilleuse, forming part of the modern department of Aisne in Picardy.
