Eugène de Mazenod was a French aristocrat and Catholic priest. When he was eight years old, Mazenod's family fled the French Revolution, leaving their considerable wealth behind. As refugees in Italy, they were poor, and moved from place to place. He returned to France at the age of twenty and later became a priest. Mazenod founded the congregation of the Missionary Oblates of Mary Immaculate. Initially focused on rebuilding the Church in France after the Revolution, their work soon spread, particularly to Canada. Mazenod was appointed Bishop of Marseille in 1837, and Archbishop in 1851.
