More information

Kosciuszko was born in the village of Mereczowszczyzna, now abandoned, near the present-day town of Kosava, Belarus. The area lay within the Grand Duchy of Lithuania, a part of the Polish-Lithuanian Commonwealth.

Kosciuszko was the son of a Polish local noble, Ludwik Tadeusz Kosciuszko, and Tekla, née Ratomska. Some Belarusian claim that Kosciuszko belonged to the old Belarusian family. He was the youngest child in a family whose lineage traced partly to Lithuanian and Ruthenian nobility and to a 15th–16th–century courtier of Polish King Sigismund I the Old, Konstanty Fiodorowicz Kostiuszko. At the time of Tadeusz Kosciuszko's birth, the family possessed modest holdings in the Grand Duchy. He was christened in both Eastern Orthodox and Roman Catholic religions. As a result of the dual baptisms, he bore the names Andrzej and Tadeusz.


In 1765 Poland's King Stanislaw August Poniatowski created a Corps of Cadets (Polish: Korpus Kadetów), on the grounds of present-day Warsaw University, to educate military officers and government officials. Kosciuszko enrolled on 18 December 1765, becoming a member of the Corps of Cadets. Since the school emphasized both military subjects and the liberal arts, his courses included world history, the history of Poland, philosophy, Latin, the Polish, German and French languages, and law, economics, geography, arithmetic, geometry and engineering. Upon graduation, he was promoted to captain.
