House of Valois-Burgundy
In 1411, Sigismund of Luxembourg lost the duchy to his niece Elisabeth because he defaulted on a loan. Elizabeth later sold the duchy to the Duke of Burgundy, Philip the Good of the House of Valois-Burgundy, who paid her off in 1444. The dukes of Burgundy had previously acquired a number of other possessions in the Low Countries, including Flanders, Artois, Hainaut, Brabant, Zeeland, Holland, and Namur; Luxembourg and these other Burgundian possessions in the Low Countries are collectively referred to during this period (1384–1482) as the Burgundian Netherlands. The male line of the dukes of Burgundy died out in 1477 when Philip's son Charles the Bold died at the Battle of Nancy, leaving Mary of Burgundy, his only child, as his heiress. After his death, Mary married Archduke Maximilian I of the House of Habsburg, who later became Holy Roman Emperor. The Burgundian Netherlands then came under the rule of the House of Habsburg, beginning the period of the Habsburg Netherlands (1482–1581).
