Mary of Burgundy, nicknamed the Rich, was a member of the House of Valois-Burgundy who ruled a collection of states that included the duchies of Limburg, Brabant, Luxembourg, the counties of Namur, Holland, Hainaut and other territories, from 1477 until her death in 1482.

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.
