On Sunday 7 October 1571 the combined Christian fleets under Don John of Austria won a famous naval victory over the Turks in the Straits of Lepanto. Thousands of Christians were liberated and the Turkish fleet was destroyed. In gratitude Pope Pius ordered an annual commemoration to Our Lady of Victory. In 1573 Pope Gregory XIII transferred the feast to the first Sunday of October with the title Feast of the Most Holy Rosary. Pope Pius X changed the date to 7 October in 1913 and In 1969 Pope Paul VI changed the name of the feast to Our Lady of the Rosary.
