Why did Louis IV want to strengthen the House of Wittelsbach?

Louis IV’s efforts to strengthen the House of Wittelsbach were primarily driven by a desire to improve his family's status and consolidate his own position as Holy Roman emperor.1

Throughout his reign, Louis faced intense diplomatic and military challenges, including conflicts with the Habsburgs, the Luxembourg dynasty, and the papacy. To secure his family's influence, he pursued several strategic goals:231

• Territorial Expansion: Louis sought to increase the family's landholdings, notably investing his son with the Margravate of Brandenburg and acquiring Holland through marriage.3
• Internal Consolidation: He worked to resolve internal family rivalries, such as the division of territories with his brother’s descendants. The Compact of Pavia in 1329 was a key instrument in this, as it divided the Wittelsbach lands into Bavarian and Palatinate lines, thereby securing the latter's support for his imperial policies.2
• Political Independence: By defending the right of the empire to elect an emperor independently of the pope, he aimed to stabilize his rule against external interference, which was essential for the long-term security of his dynasty.1
