Consecration of Russia and Ukraine to the Immaculate Heart of Mary
In 1917 Our Lady appeared to three shepherd children during six apparitions at the Cova da Iria, in Fátima, Portugal. The children were Lúcia dos Santos and her cousins Francisco and Jacinta Marto.
Our Lady of Fatima is said to have revealed 3 secrets to these young peasant children, the second of which recommends devotion to the Immaculate Heart of Mary as a way to save souls and bring peace to the world.
During the relevation of the second secret, the children were told of the end of World War I, but were also forewarned of WW2 if people did not stop offending God. Our Lady also asked for the consecration of Russia to her Immaculate Heart, with the warning that if request was not met, Russia would spread “its errors throughout the world, promoting wars and persecution of the Church.”. However, the appearance of the Holy Mother on this occasion concluded with the promise that,
"the Immaculate Heart would triumph. The Holy Father would consecrate Russia to Mary, and a period of peace would be granted to the world."
