In the Western Rite Vicariate of the Antiochian Orthodox Church, the feast is optionally celebrated on 7 October, under the title The Holy Rosary of the Blessed Virgin Mary.

[2] According to Dominican tradition, in 1206, Dominic de Guzmán was at the Monastery of Our Lady of Prouille, in France, attempting to convert the Albigensians back to the Catholic faith.

[5] In thanksgiving for victory at the Battle of Bouvines in July 1214, Philip Augustus of France founded the Abbey of Notre Dame de la Victoire, between Senlis and Mont l'Evêque.

On 7 October 1571, the Holy League, a coalition of southern European Catholic maritime states, sailed from Messina, Sicily, and met a powerful Ottoman fleet in the Battle of Lepanto.

[11] Combined with the Great Siege of Malta (1565) and the unfolding events in Morocco where the Sa'adids successfully spurned the Ottoman advances, it confined Turkish naval power to the eastern Mediterranean.

Although the Ottoman Empire was able to build more ships, it never fully recovered from the loss of trained sailors and marines, and was never again the Mediterranean naval power it had become the century before when Constantinople fell.

[14] Leo XIII raised the feast to the rank of a double of the second class and added to the Litany of Loreto the invocation "Queen of the Most Holy Rosary".
