The Holy Roman Empire and the Ottoman Empire were at war. Vienna had
been under siege for months. On 11 September a coalition of Christian
forces, a Holy League blessed by Bl. Pope Innocent XI, arrived with Jan
III Sobieski, King of Poland, to lift the siege.
When he saw that the Turks were about to breach the walls of the city, Sobieski attacked earlier than he had intended.
On 12 September at 4 am the battle was closed. Sobieski had called
on the protection of Our Lady of Czestochowa before the battle.
He sent his forces of 81,000 against the Turks’ 130,000. In the
afternoon Sobieski led a downhill charge which broke the Turkish line
and then seized the abandoned tent of the Ottoman general who had fled.
The Battle of Vienna halted the spread of the Ottoman Empire eastward into the rest of Europe.
Bl. Innocent XI commemorated the victory at Vienna by extending the
feast of the Holy Name of Mary, which had been observed in Spain and by
the Carmelites, to the whole Latin Church. One of the pair of churches
in Rome near the Forum of Trajan is dedicated to the Name of Mary.
Today is the Feast of the Holy Name of Mary, which in part
commemorates the defeat of the Islamist Ottoman Turks by Jan Sobieski at
the walls of Vienna.
Concede, quaesumus, omnipotens Deus:
ut fideles tui,
qui sub sanctissimae Virginis Mariae Nomine
et protectione laetantur;
eius pia intercessione
a cunctis malis liberentur in terris,
et a gaudia aeterna pervenire mereantur in coelis.
