# Louis I, Duke of Bourbon

Louis I, called the Lame (1279 – 1341) was a French prince du sang, Count of Clermont-en-Beauvaisis and La Marche and the first Duke of Bourbon, as well as briefly the titular King of Thessalonica from 1320 to 1321.

## Life

Louis was born in Clermont-en-Beauvaisis, the son of Robert, Count of Clermont, and a grandson of King Louis IX of France. Louis' mother was Beatrix of Burgundy, heiress of Bourbon and a granddaughter of Hugh IV, Duke of Burgundy.
He fought on the losing side at the Battle of the Golden Spurs (1302) and at the Battle of Mons-en-Pévèle (1304), but managed to escape unharmed. In 1310, he was made Grand Chambrier of France. Louis was crucesignatus in 1316 founding a confraternity called the Holy Selpulchre. On 13 September 1318, Philip V of France designated Louis, who had drawn up a preliminary crusading plan, as captain-general of his crusading army, however the loss of the Franco-Papal fleet in 1319 to the Ghibbelines at Genoa sidelined their efforts.
On 14 April 1320, Louis offered 40,000 livres to Odo IV, Duke of Burgundy for the rights to the title King of Thessalonica, however Philip of Taranto stepped in and offered the same amount which Odo accepted. The terms of the agreement also included the marriage of Philip's oldest son and Louis' daughter, Beatrice.
In 1327, Charles IV of France persuaded Louis to exchange the County of Clermont for that of La Marche, and elevated Bourbon to a duchy-peerage. By 1331, Clermont was restored to him since he was part of Philip VI's small circle of trusted advisors. Louis continued to be an integral part of French crusading plans until 1336, when Pope Benedict XII cancelled Philip VI's crusade.
Duke Louis is reported to have been somewhat mentally unstable, in particular having nervous breakdowns. The trait is believed to have been hereditary, with his granddaughter Joanna of Bourbon, her son, King Charles VI of France, and Charles' grandson, King Henry VI of England, all displaying similar symptoms.
He was buried in the now-demolished church of the Couvent des Jacobins in Paris.
