The September 1590 papal conclave, attended by 54 cardinals, elected Cardinal Giovanni Battista Castagna as Pope Urban VII.[1][2]
The conclave lasted a week, and was heavily swayed by the influence of the twenty-two Spanish cardinals.[3][4][2] Castagna, who had been favored by Sixtus V as a successor and was on the list of candidates whom Philip II of Spain had approved, was a favorite from the beginning,[1][2][5] although a significant opposing faction supported Marco Antonio Colonna.[1][6] Castagna's poor health, which would ultimately kill him after a papacy of only thirteen days, made him a more palatable candidate to cardinals who were outraged at Philip's attempts to sway the election.[2]
Contemporary newspapers reported that a disagreement between Cardinals Ascanio Colonna and Francesco Sforza di Santa Fiora during the conclave nearly became violent.[7]
