Ivan Merz

Ivan Merz (16 December 1896 − 10 May 1928) was a Catholic layman from Bosnia and important supporter of the Catholic Church in Croatia. Merz promoted the Liturgical Movement in Croatia and together with Ivo Protulipac, he established a movement for the young people, Hrvatski orlovski savez ("The Croatian Union of the Eagles"), inspired by the Eucharistic Crusade, which he had encountered in France. He was beatified by Pope John Paul II in 2003.

Merz entered military service for Austro-Hungarian Army as a young adult, completed it after three months and began studying in Vienna in 1915. During the First World War he was drafted into the army and fought on the Italian front. After the World War, Merz devoted himself entirely to serving in the Roman Catholic Church and took a vow of chastity.
