Robert II, called the Pious (French: le Pieux) or the Wise (French: le Sage), was King of the Franks from 996 until his death. The second reigning member of the House of Capet, he was born in Orléans to Hugh Capet and Adelaide of Aquitaine.
Immediately after his own coronation, Robert's father Hugh began to push for the coronation of Robert. "The essential means by which the early Capetians were seen to have kept the throne in their family was through the association of the eldest surviving son in the royalty during the father's lifetime," Andrew W. Lewis has observed, in tracing the phenomenon in this line of kings who lacked dynastic legitimacy. Robert had begun to take on active royal duties with his father in the early 990s. In 991, he helped his father prevent the French bishops from trekking to Mousson in the Kingdom of Germany for a synod called by Pope John XV, with whom Hugh was then in disagreement.
The kingdom Robert inherited was not large, and in an effort to increase his power, he vigorously pursued his claim to any feudal lands that became vacant, usually resulting in war with a counter-claimant. In 1003, his invasion of the Duchy of Burgundy was thwarted, and it would not be until 1016 that he was finally able to get the support of the Church to be recognized as Duke of Burgundy.
The pious Robert made few friends and many enemies, including his own sons: Hugh, Henry, and Robert. They turned against their father in a civil war over power and property. Hugh died in revolt in 1025. In a conflict with Henry and the younger Robert, King Robert's army was defeated, and he retreated to Beaugency outside Paris, his capital. He died in the middle of the war with his sons on 20 July 1031 at Melun. He was interred with Constance in Saint Denis Basilica and succeeded by his son Henry, in both France and Burgundy.
