Mennonites originated as a branch of the 16th century Anabaptist movement that formed as a radical expression of the Protestant Reformation. They are a pacifist Christian group that began immigrating to Latin American countries like Mexico, Bolivia, and Paraguay in the early 20th century, with over 3,000 settling in Mexico's Chihuahua state in 1922 after being invited by the Mexican government. The main language used by Mennonites in daily communication is Plautdietsch, a dialect of the Danzig region, and they sing religious songs during ceremonies, though some communities restrict music and cultural freedoms more for youth.
