Louis IX (also known as Louis the Rich; 23 February 1417 – 18 January 1479), (German: Ludwig IX, Herzog von Bayern-Landshut) was Duke of Bavaria-Landshut from 1450. He was a son of Henry XVI the Rich and Margaret of Austria.


Louis succeeded his father in 1450. He was the second of the three famous rich dukes, who reigned Bavaria-Landshut in the 15th century. Their residence was Trausnitz Castle in Landshut, a fortification which attained enormous dimensions.

Since Louis invaded the imperial free cities of Dinkelsbühl and Donauwörth in 1458 he disputed with Frederick III, Holy Roman Emperor, until peace was made in Prague in 1463. In 1462 Louis defeated his enemy Albert III, Margrave of Brandenburg, who tried to extend his influence in Franconia in the battle of Giengen. Louis expelled all Jews who rejected baptism from his duchy.

In 1472 Louis founded the Ludwig-Maximilians-University in Ingolstadt, which was moved to Landshut in 1800 and finally to Munich. In 1475 he organized the Landshut Wedding of his son George with the princess Hedwig Jagiellon, a daughter of King Casimir IV of Poland, one of the most splendid festivals of the Middle Age.
