Marie de la Paix Giuliani was an Italian nun and missionary of the Franciscan Missionaries of Mary who lived from 1875 to 1900. Born Marianna Giuliani in L'Aquila, she experienced a difficult childhood before joining her religious order. She traveled to China in 1899 to assist in establishing an orphanage in Taiyuan. During the Boxer Rebellion, she was killed alongside her fellow sisters in the Taiyuan massacre, having refused to renounce her religious convictions.
