How did Pope Innocent III strengthen the papal court system?

Pope Innocent III significantly strengthened the papal court system and the broader hierarchical structure of the church through several key reforms and actions:

• Curial Reform: Upon his election, Innocent prioritized the reform of the Roman Curia, which had been in need of reorganization.12
• Judicial Reorganization: He reorganized the papal judicial system and demonstrated great skill in legal affairs, often participating personally in cases brought to the papal court on appeal.2
• Centralization of Authority: Innocent mandated the subordination of bishops to the pope, asserting that only the papacy could approve episcopal resignations, translations, and depositions. In doing so, he effectively dismantled the older, decentralized institutions that had characterized the early Middle Ages.2
• Expansion of Jurisdiction: He actively extended papal authority into new areas, including the marital affairs of Christian princes and the legal pursuit of heresy, for which he applied the procedural norms of ancient Roman treason trials.2

These efforts transformed the theory of papal monarchy, establishing the pope as a central authority with wide-ranging legislative and judicial power.2
