 Serafini, supported by Gaetano Cardinal de Lai, was the leading candidate for the conservative cardinals, who believed he would continue the teachings and policies of Pius X.His main opponent was the more progressive Archbishop of Bologna, Giacomo della Chiesa, who was eventually elected on the tenth ballot—according to Francis A. Burkle-Young, the final tally was della Chiesa 38, Serafini 18, and Agostino Richelmy 1—and took the name "Benedict XV".Serafini was made Prefect of the Sacred Congregation of Religious on 27 January 1916.
