At the first appearance, Mary asked the children to return to that spot on the thirteenth of each month for the next six months. She also asked them to learn to read and write and to pray the rosary to obtain peace for the world and the end of the war. They were to pray for sinners and for the conversion of Russia, which had recently overthrown Czar Nicholas II and was soon to fall under communism. Up to 90,000 people gathered for Marys final apparition on October 13, 1917.
Less than two years later, Francisco died of influenza in his family home. He was buried in the parish cemetery and then re-buried in the Fatima basilica in 1952. Jacinta died of influenza in Lisbon, offering her suffering for the conversion of sinners, peace in the world and the Holy Father. She was re-buried in the Fatima basilica in 1951. Their cousin, Lucia dos Santos, became a Carmelite nun and was still living when Jacinta and Francisco were beatified in 2000. Sister Lucia died in February 2005 at the age of 97. The shrine of Our Lady of Fatima is visited by up to 20 million people a year.
