Robert II, Duke of Burgundy

Robert II was Duke of Burgundy between 1272 and 1306 as well as titular king of Thessalonica.
Robert was the third son of Hugh IV, Duke of Burgundy, and Yolande of Dreux.
He married Agnes, youngest daughter of Louis IX of France, in 1279. They had the following children:

In 1284, Robert was invested with the duchy of Dauphiné by Rudolf of Habsburg. This was followed by two years of warfare which was ended when King PhilipIV of France paid Robert 20,000 livres tournois to renounce his claim to the Dauphiné. He was among the French negotiators for the 1303 Treaty of Paris that ended the 1294–1303 Gascon War.
Robert ended the practice of giving away parts of the Burgundian estate to younger sons and as dowries to the daughters. From then on, the entire duchy passed via primogeniture unfragmented to the duke's eldest son.
