A general of the Polish Army and a royal Chamberlain[1], Mokronowski took part in both the Polish–Russian War of 1792 (War in the Defence of the Constitution) and Kościuszko's Uprising of 1794.
Stanisław Mokronowski was born in 1761 to Ludwik Mokronowski and Józefa née Czosnowska. Educated by Jesuits, he later studied at the Szkoła Rycerska (Knight's School, also known as the Cadet Corps) in Warsaw, and later in Paris. He entered the military service in Poland, but for a few years he served in the French military. He returned to Poland in 1788, and on the sejmik at Wyszogród land he was elected the deputy to the national Sejm (parliament), thus becoming a member of the famous Great Sejm[2]. He became allied to the Poniatowski family.
In 1792, during the War in the Defence of the Constitution he held the rank of vicebrigadier (wicebrygadier), and after distinguishing himself at the battle of Zieleńce was promoted to the rank of Lieutenant General. In 1793, he married Maria Marianna Sanguszko-Kowelska.
