Ever since Our Lady gave the Holy Rosary to Saint Dominic, Christians have prayed The Rosary to ask for defense and victory over enemies.
One miraclulous rosary campaign was in 1571, before the Battle of Lepanto, when Pope Pius V asked all of the faithful to say the rosary and implore our Blessed Mother's prayers, under the title Our Lady of Victory, that our Lord would grant victory to the Christians.
Although the Moslem fleet outnumbered that of the Christians in both vessels and sailors, the forces were ready to meet in battle. The Christian flagship flew a blue banner depicting Christ crucified. On October 7, 1571, the Moslems were defeated at the Battle of Lepanto.
The following year, Pope St. Pius V established the Feast of the Holy Rosary on October 7, where the faithful would not only remember this victory, but also give thanks to the Lord for all of His benefits and remember the powerful intercession of our Blessed Mother.
Today, we need a new Lepanto. All Christendom needs to come together to pray the Holy Rosary to defeat the new threat of ISIS.
“Give me an army saying the Rosary and I will conquer the world.”
– Blessed Pope Pius IX
