The Duchy of Brabant, a state of the Holy Roman Empire, was established in 1183. It developed from the Landgraviate of Brabant of 1085–1183, and formed the heart of the historic Low Countries. The Duchy comprised part of the Burgundian Netherlands from 1430 and of the Habsburg Netherlands from 1482, until it was partitioned after the Dutch revolt of 1566–1648.

The 1648 Peace of Westphalia ceded present-day North Brabant (Dutch: Noord-Brabant) to the Generality Lands of the Dutch Republic, while the reduced duchy remained part of the Habsburg Netherlands until French Revolutionary forces conquered it in 1794 — a change recognized by the Treaty of Campo Formio in 1797.

Today all the duchy's former territories, apart from exclaves, are in Belgium except for the Dutch province of North Brabant.
