Clermont was the starting point of the First Crusade, in which Christendom sought to free Jerusalem from Muslim domination. Pope Urban II preached the crusade in 1095, at the Second Council of Clermont. In 1120, following repeated crises between the counts of Auvergne and the bishops of Clermont and in order to counteract the clergy's power, the counts founded the rival city of Montferrand on a mound next to the fortifications of Clermont, on the model of the new cities of the Midi that appeared in the 12th and 13th centuries. Until the early modern period, the two remained separate cities: Clermont, an episcopal city; Montferrand, a comital one.
