Robert II, Duke of Burgundy

Robert II, Duke of Burgundy, born in 1248, was a prominent monarch who ruled from 1272 until 1306. He was the third son of Hugh IV, Duke of Burgundy, and Yolande of Dreux. His reign was marked by significant political maneuvers, including his role as the titular king of Thessalonica.

In 1279, Robert married Agnes, the youngest daughter of Louis IX of France, strengthening ties between the Burgundian and French royal families. Together, they had several notable children, including Hugh V, Duke of Burgundy, and Margaret, who married King Louis X of France. Robert's lineage continued to influence European nobility through strategic marriages.

In 1284, Robert was invested with the duchy of Dauphiné by Rudolf of Habsburg. However, this claim led to two years of conflict, ultimately resolved when King Philip IV of France compensated Robert with twenty thousand livres tournois to relinquish his claim. His diplomatic skills were further demonstrated when he participated in the negotiations for the 1303 Treaty of Paris, which concluded the Gascon War.

Robert II is also remembered for his significant reforms regarding the inheritance of the Burgundian estate. He ended the practice of distributing parts of the duchy to younger sons and as dowries for daughters, ensuring that the entire duchy would pass unfragmented to the eldest son, thus preserving the integrity of the family estate.
