The Montenegrin-Ottoman War (1861-1862) was a war between the Principality of Montenegro and the Ottoman Empire that took place between 1861 and 1862. The war ended and Montenegro had to acknowledge Ottoman suzerainty.
In 1861 Montenegro encouraged a revolt in Herzegovina by their ethnic kinsmen. Ottoman forces under Omar Pasha are first defeated but eventually prevail. The Montenegrins are pressed by the Great Powers and withhold their forces from fighting in Herzegovina. The Ottoman army then invades Montenegro. After the unsuccesfull defense of Ostrag by Mirko Petrović, the Montenegrins are defeated.
The war ends with the Convention of Scutari of August 31, 1862. Montenegro is forced to acknowledge Ottoman suzerainty, however the terms are generous because the Ottomans want to win Montenegrin goodwill. The borders of 1859 are restored, the Montenegrins are allowed to import any goods, except arms, through Ottoman territory and to rent agricultural lands.
