Pope Pius X

Pope Pius X was head of the Catholic Church from 4 August 1903 until his death in August 1914. He was known for opposing modernist interpretations of Catholic doctrine, and for promoting liturgical reforms and Thomist scholastic theology. He initiated the preparation of the 1917 Code of Canon Law, the first comprehensive and systemic work of its kind, which was ultimately promulgated by his successor. He is venerated as a saint in the Catholic Church.
