Flag of the Duchy of Brabant - Historical Symbol of the Low Countries #1767812 (License: Personal Use)

This flag represents the former Duchy of Brabant, a medieval state in the Low Countries, whose heraldic symbol-the red frog (or toad)-dates back to the 12th century. The design features a white diagonal band (bend) across a blue field, bearing three stylized red frogs in sequence, reflecting regional pride and historical continuity. Though the duchy no longer exists politically, its flag remains influential in modern Belgian and Dutch regional identities.
