March–April 1605 conclave

The March–April 1605 papal conclave was convened on the death of Clement VIII and ended with the election of Cardinal Alessandro de' Medici as Pope Leo XI. It was the first of the two papal conclaves in 1605; Leo XI died on 27 April 1605, just twenty-six days after he was elected. The conclave was dominated by conflict over whether Cardinal Cesare Baronius should be elected pope, and Philip III of Spain excluded both Baronius and the eventually successful candidate, Medici.
