In 1917, Our Lady appeared to three children near Fatima, Portugal and specifically asked them for Russia to be consecrated to her Immaculate Heart.
To prevent [another World War], I shall come to ask for the consecration of Russia to my Immaculate Heart and the Communion of reparation on the first Saturdays.

In St. Peter’s Basilica in 1984, Pope John Paul II consecrated the whole world in front of the statue of Our Lady of Fatima, inviting all other bishops to join him in prayer, to the Immaculate Heart of Mary.
According to the Vatican, Sr. Lucia confirmed that this consecration fulfilled the wishes of Our Lady of Fatima.
Sister Lucia personally confirmed that this solemn and universal act of consecration corresponded to what Our Lady wished («Sim, està feita, tal como Nossa Senhora a pediu, desde o dia 25 de Março de 1984»: «Yes it has been done just as Our Lady asked, on 25 March 1984»: Letter of 8 November 1989).
