In which region where many people became Roman Catholics?

Answer 1

Many people became Roman Catholics in regions such as Latin America, particularly in countries like Mexico, Brazil, and Argentina, as a result of Spanish and Portuguese colonization in the 15th and 16th centuries. Additionally, parts of Southern Europe, including Italy and Spain, have historically been strongholds of Catholicism. The spread of Catholicism also occurred in various parts of Africa and Asia, influenced by missionary activities.
