Why did Leo X make peace with Francis I after the Battle of Marignano?

Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

Following the Battle of Marignano in 1515, where Francis I decisively defeated the coalition forces, Leo X was compelled to make peace to navigate the shifting power dynamics in Italy.

The pope’s decision to reconcile with the French king was a pragmatic political maneuver. By securing peace, Leo X was able to negotiate the Concordat of Bologna in 1516. This agreement fundamentally reshaped church-state relations in France by granting the French monarchy significant authority to nominate bishops, abbots, and priors, while the papacy retained specific rights over other benefices. This strategic compromise allowed the pope to maintain a degree of influence and stability in the region following the military setback.1
