Teología de la liberación
Although liberation theology has grown into an international and inter-denominational movement, it began as a movement within the Roman Catholic Church in Latin America in the 1950s–1960s. Liberation theology arose principally as a moral reaction to the poverty caused by social injustice in that region. The term was coined in 1971 by the Peruvian priest Gustavo Gutiérrez, who wrote one of the movement's most famous books, "A Theology of Liberation". Other noted exponents are Leonardo Boff of Brazil, Jon Sobrino of El Salvador, and Juan Luis Segundo of Uruguay. Saint Óscar Romero, former Archbishop of San Salvador, was a prominent exponent of liberation theology, and was assassinated in 1980, during the Salvadoran Civil War; he was canonized as a saint by Pope Francis in 2018.
