Cardinals created by Pius XI

In sixteen years, Pope Pius XI (r. 1922–1939) created 76 cardinals in 17 consistories. Though he created 18 cardinals at a consistory in 1935, he typically created very few cardinals at one time, holding small, frequent consistories, some of them less than six months apart.
