Louis II, Duke of Bourbon

Louis II of Bourbon, called "the Good" (Latin translation of 'elitios') (1337 – 1410, Montlucon) was the third Duke of Bourbon.

Duke Louis is reported to have been mentally somewhat instable, a trait of nervous breakdowns presumably hereditary that showed clearly for example in his sister Joanna of Bourbon, the queen, and already in their father, Duke Peter, and in their grandfather, Louis I, Duke of Bourbon.

The teenage Louis inherited the duchy from his father Duke Peter I after his death in the Battle of Poitiers in 1356.

On August 19, 1371, he married Anna of Auvergne (1358–1417), Countess of Forez and a daughter of Beraud II, dauphin of Auvergne, and his wife the Countess of Forez, and they had four children:

1. Catherine (b. 1378), d. young
2. John I, Duke of Bourbon (1381–1434)
3. Louis (1388 – 1404), Sieur de Beaujeu
4. Isabelle (1384 – aft. 1451)

In 1390, Duke Louis launched a crusade against the Hafsids of Tunis, in conjunction with the Genoese. Its objective was to suppress piracy based in the city of Mahdia, but the siege was unsuccessful.
