The Anniversary of the Death of General José de San Martín is observed in Argentina every August 17. This public holiday commemorates the life and contributions of San Martín, a key figure in the South American struggle for independence from Spanish colonial rule. Born in Yapeyú, Argentina, he became a national hero for his leadership in liberating Argentina, Chile, and Peru. San Martín returned to Argentina in 1812 and organized military campaigns against Spanish forces, ultimately leading the Army of the Andes in 1818. He spent his final years in France, passing away on August 17, 1850, at the age of 72. The day is marked by various commemorative activities, and a related observance occurs on the third Monday in August.
