La Semana Trágica was a series of violent events that took place in Buenos Aires, Argentina, from January 7 to January 14, 1919. It began as a labor strike by workers in the metal industry demanding better wages and working conditions. The government responded with force, leading to clashes between police and workers, resulting in numerous deaths and injuries. The conflict escalated into widespread riots and violence, with various groups, including anarchists and socialists, becoming involved. The government declared a state of emergency, and military forces were deployed to restore order. Ultimately, La Semana Trágica highlighted the social tensions and labor struggles in early 20th-century Argentina.
