The Concordat of Bologna (1516), marking a stage in the evolution of the Gallican Church, was an agreement between King Francis I of France and Pope Leo X that Francis negotiated in the wake of his victory at Marignano in September 1515. The groundwork was laid in a series of personal meetings of king and pope in Bologna, 11–15 December 1515. The concordat was signed in Rome on 18 August 1516.
