Robert II of Burgundy

Robert II (1248 – 21 March 1306) was Duke of Burgundy from 1272 and titular King of Thessalonica, succeeding his father Hugh IV. In 1279 he married Agnes, daughter of Louis IX of France; their son Odo IV inherited the duchy.

In 1284 his brother-in-law Rudolf I of Germany invested him with the Dauphiné, but two years of war ended when Philip IV bought his claim. He helped negotiate the 1303 Treaty of Paris ending the Gascon War, and ended the partition of the duchy by imposing primogeniture.
