Treaty of Warsaw
The Holy League (Latin: Sacra Ligua) of 1684 was an alliance of European nations formed during the Great Turkish War. Born out of the Treaty of Warsaw, it was founded as a means to prevent further Ottoman expansion into Europe. This consolidation of a large portion of Europe's military might led to unprecedented military successes, with large areas of previously ceded land recovered in Morea, Dalmatia and Danubia in what has been called a "14th crusade".
