Namely, Pius IX. he was pope for as long as 31 years, 7 months and 23 days, which is considerably longer than any other pope for whom the exact length of the pontificate can be calculated. Note that in second place in the length of the pontificate is John Paul II, at 26 years, 5 months and 18 days. Thus, Pius IX. he was in the papal position for about five years longer than John Paul II.
Pope Blessed Pius IX he was born in 1792 under the name of Giovanni Maria Mastai-Ferretti in the town of Senigallia not far from Ancona. He was 54 years old at the time of his election as pope, and he experienced a fairly high 86 years of age.
