Did you know?

Beginning around 1540, an order of Catholic priests known as the Jesuits began to send its members to many parts of the world to convert peoples who believed in other gods to Christianity. Wherever they went, the Catholic missionaries built central buildings for their religious work, and the buildings themselves became known as missions; many 17th-century missions in the American West and Southwest are now preserved as museums. Their foes, the Protestants, soon began sending out their own missionaries, and today Protestant missionaries are probably far more numerous.
