'''Pope Pius IX''' (May 13, 1792-February 7, 1878) - born '''Giovanni Maria Mastai-Ferretti''' -  was the [[Pope]] and leader of the [[Catholic church]] from June 16, 1846 to February 7, 1878 the longest reign in Church history. He convened the [[First Vatican Council]], which declared the Pope was infallible under certain conditions.  He encouraged the rapid growth of religiosity among lay people, which strengthened the Church; he especially promoted devotion to the Sacred Heart of Jesus as symbol of love.  He fought every form of modern ideas inside the Church, especially through the [[Syllabus of Errors]] of 1864. Outside the Church he fought against [[secularism]] and helped the German Catholics defeat the [[Kulturkampf]].
