Passarowitz. A well-built town of European Turkey, in the province of Servia, 5 miles south of the Danube, and 15 miles east of Semendria. The town is chiefly noteworthy for the treaty which was signed here by Prince Eugène and the grand viziers, July 21, 1718. By this treaty, which put an end to the war undertaken by the Turks against Venice in 1714 for the conquest of the Morea, a truce of twenty-five years was established, and the Banat of Temesvars, the western portion of Wallachia and Servia, the town and territory of Belgrade, and a part of Bosnia, were secured to the house of Austria.

Passau. A picturesque, fortified, frontier town of Bavaria, at the confluence of the Inn and the Ilz with the Danube, 90 miles east-northeast from Munich.

The treaty whereby religious freedom was established, was ratified here between the emperor Charles V. and the Protestant princes of Germany, July 31, 1552.
