Louis X, was Duke of Bavaria, together with his older brother William IV, Duke of Bavaria.
Background
His parents were Albert IV and Kunigunde of Austria, a daughter of Emperor Frederick III. Though his father had determined the everlasting succession of the firstborn prince in 1506 Louis refused a spiritual career with the argument that he was born before the edict became valid.
Career
Both dukes also suppressed the uprising of farmers in South Germany in their duchies in 1525. Since Louis claimed the Bohemian crown Bavaria was in opposition to the Habsburgs until 1534 when both dukes reached an agreement with Ferdinand I in Linz. After his visit in Italy Louis built the first Renaissance palace constructed north of the Alps, the Landshut Residence which was modelled 1537 - 1543 after the Palazzo del Te in Mantua.
This was finally the end of the divisions of the duchy of Bavaria.
