Pyotr Bagration was a Russian general and prince of Georgian origin, prominent during the Napoleonic Wars.
Bagration, a member of the Bagrationi dynasty, was born in Kizlyar or in Tbilisi. His father served as an officer in the Imperial Russian Army, in which Bagration also enlisted in 1782. Pyotr Ivanovich Bagration began his military career serving in the Russo-Circassian War of 1763–1864 for a couple of years. Afterwards he participated in a war against the Ottomans and the capture of Ochakov in 1788. Later he helped suppress the Kościuszko Uprising of 1794 in Poland and capture Warsaw. During Russia's Italian and Swiss campaigns of 1799 against the French, he served with distinction under Field Marshal Alexander Suvorov.
In 1805 Russia joined the coalition against Napoleon. After the collapse of the Austrians at Ulm in October 1805, Bagration won praise for his successful defense in the Battle of Schöngrabern that allowed Russian forces to withdraw and unite with the main Russian army of Mikhail Kutuzov.
