Feldmarschall Johann Karl, Graf von Kolowrat-Krakowsky (21 December 1748 – 5 June 1816) joined the Austrian army, fought against the Kingdom of Prussia and Ottoman Turkey before being promoted to general officer rank.

He was the last governor of the Kingdom of Serbia in 1791, having succeeded Count George Olivier of Wallis and acceded to those territories in accordance to the Treaty of Sistova.

Born in Prague on 21 December 1748, Kollowrat's military career began in 1766 when he joined the Austrian army.

[1] He succeeded in 1791 count George Olivier Wallis as supreme military commander of the Habsburg forces in Serbia.

He distinguished himself while directing the batteries at the Siege of Kehl in 1796–97 and received the Commander's Cross Military Order of Maria Theresa for his efforts.

[2] At the Battle of Hohenlinden, the army commander Archduke John of Austria rode with Kollowrat's 22,000-strong Austro-Bavarian column.

After severe fighting, Marshal Nicolas Soult's corps broke Kollowrat's Austrians and drove them off the field.

[5] In 1809, Kollowrat led the II Corps during the Battle of Eckmühl where it was unengaged because it operated north of the Danube.

[6] On the second day of the Battle of Wagram, Archduke Charles launched the corps of Kollowrat and Johann von Klenau in a dangerous assault against the French left flank.
