Holy League (1684)

The Holy League (Latin: Sacra Ligua) of 1684 was an alliance organized by Pope Innocent XI to oppose the Ottoman Empire in the Great Turkish War. The League's initial members were the Papal States, the Holy Roman Empire under Habsburg Emperor Leopold I, the Polish–Lithuanian Commonwealth of John III Sobieski, and the Venetian Republic; the Tsardom of Russia joined the League in 1686. The alliance lasted until the Treaty of Karlowitz brought an end to the war in 1699.

Pope Innocent was aided by Capuchin Friar Marco d'Aviano during the formation of the League.
