Tadeusz Kościuszko was a Polish-Lithuanian military engineer and leader known for his role in the American Revolutionary War. He contributed significantly to the American cause by designing fortifications and training troops, earning the respect of figures like George Washington. After the war, he returned to Poland, where he became a national hero for his efforts to fight for Polish independence. In 1794, Kościuszko led the Kościuszko Uprising, a rebellion against foreign domination in Poland. Despite initial successes, the uprising was ultimately suppressed, leading to the partitioning of Poland. Kościuszko's legacy endures as a symbol of freedom and resistance against oppression.
