The Christianization of Latin America began with its discovery by Christopher Columbus in 1492. It is the work of both countries of the Pyrenean Peninsula - Spain and Portugal. Pursuant to the bull of May 4, 1493, Pope Alexander VI established the demarcation border between the Spanish possessions in America and the Portuguese and obliged both royal courts to prepare missionaries and introduce the Christian faith. The Spanish expeditions and conquests of Central and South America, which began with Columbus' first expedition (1492), lasted until 1534, when Francesco Pizarro conquered the Inca country in today's Peru. In accordance with the papal recommendation, several religious priests took part in Columbus' second expedition in 1493.
