Louis' eldest son, Pierre, founded the Bourbon-Busset family.
Conflict over the bishopric
Philip secured for him in 1456 the Prince-Bishopric of Liège, by influencing Pope Callixtus III, and removing the 69-year-old John of Heinsberg. Given the strategic position of Liège almost enclosed by Burgundian possessions, Louis was a poor choice because his behavior quickly led to troubles, permitting French meddling. The citizens rejected the new bishop and the Burgundian influence, which led to the Liège Wars. Louis was exiled to Maastricht. Marc de Bade was put in place by the Liégeois, who fought under Raes van Heers, restored the bishop, but Liège lost its sovereignty. Another revolt in 1467 was crushed at the Battle of Brustem. In the summer of 1468, Louis was back in his prince-bishopric, after a papal legate had intervened, but was captured at Tongeren by a raiding party from Liège, at that time again asserting independence of Charles the Bold of Burgundy. An unlikely alliance of Charles with Louis XI, who in 1465 had helped the Liégeois against the bishop, saw Bishop Louis released. Liège was taken, and sacked on 30 October 1468. In gratitude Louis gave Charles the Horn of St Hubert, now in the Wallace Collection
Later life
Louis sold Condé and Leuze to Marie de Montmorency. In 1477, Charles the Bold was killed, and his daughter and heiress Mary of Burgundy was forced to sign the Peace of Saint-Jacques, consolidating the bishop's position but returning sovereignty to Liège. He was at this time amongst the advisers of Mary who wanted her to marry the futureCharles VIII of France, then Dauphin of France. Louis ruled until 30 August 1482, when he was assassinated by William de la Marck, an adventurer who from 1478 had been operating against the territory from the Castle of Logne.
In literature
The murder of Louis is depicted in the novelQuentin Durward by Sir Walter Scott, but its historical details are far from accurate. Scott's own introduction admits this: "In assigning the present date to the murder of the Bishop of Liege, Louis de Bourbon, history has been violated. It is true that the Bishop was made prisoner by the insurgents of that city. It is also true that the report of the insurrection came to Charles with a rumour that the Bishop was slain, which excited his indignation against Louis, who was then in his power. But these things happened in 1468, and the Bishop's murder did not take place till 1482."
