Óscar Romero was a Roman Catholic archbishop in El Salvador known for his outspoken advocacy for human rights and social justice during the late 20th century. He became a prominent voice against the violence and oppression faced by the poor in his country, particularly during the Salvadoran Civil War. Romero was assassinated on March 24, 1980, while celebrating Mass, a tragic event that drew international attention to the struggles in El Salvador. He is remembered as a martyr and a symbol of the fight for justice, and he was canonized as a saint by the Catholic Church in 2018.
