Beginning on May 13, 1917, in Fatima, Portugal, Mary appeared six times to three children; Lucia, Jacinta, and Francisco. While many believed the children when they shared what they saw, many were skeptical. At this time, the world was in the midst of World War I and in desperate need of peace. Our Lady came to spread the message of praying the rosary daily and doing penance in order to bring peace to the world and an end to the war. During her last apparition in Fatima on October 13, 1917, over 70,000 people witnessed the "miracle of the sun" and came to believe. Now, Our Lady of Fatima is one of the most well-known Marian apparitions in history and is widely believed to be true within the Church.
