In 1431, the Church and the adjacent Convent of the Dominicans was the site of a Papal conclave. The city of Rome was in an uproar upon the death of Pope Martin V (Colonna), whose family had dominated Roman political life for fifteen years, and enriched themselves on the wealth of the Church. There was fighting in the streets on a daily basis, and the Plaza in front of the Minerva, because of the configuration of streets, houses, church and monastery, could easily be fortified and defended. The Sacristy of the Church served as the meeting hall for the fourteen cardinals (out of nineteen) who attended the Conclave, which began on 1 March 1431. The dormitory of the monks in the Convent to the immediate north of the Church, served as the living quarters for the cardinals and their refectory and kitchen. On 3 March they elected Cardinal Gabriele Condulmaro, who took the name Eugenius IV. A second Conclave was held at the Minerva, on 4–6 March 1447, following the death of Pope Eugenius, once again in the midst of disturbances involving the Orsini supporters of Pope Eugenius and his enemies the Colonna. Eighteen cardinals (out of a total of twenty-six) were present and elected Cardinal Tommaso Parentucelli da Sarzana as Pope Nicholas V.
