During the Age of Discovery, the Roman Catholic Church established a number of Missions in the Americas and other colonies in order to spread Christianity in the New World and to convert the indigenous peoples. At the same time, missionaries such as Francis Xavier as well as other Jesuits, Augustinians, Franciscans and Dominicans were moving into Asia and the Far East. The Portuguese sent missions into Africa. The most significant failure of Roman Catholic missionary work was in Ethiopia. Although its ruler, Emperor Susenyos, had publicly declared his conversion to Catholicism in 1622, the declaration of Roman Catholicism as the official religion in 1626 led to increasing civil war. Following Susenyos' abdication, his son and successor Fasilides expelled archbishop Afonso Mendes and his Jesuit brethren in 1633, then in 1665 ordered the remaining religious writings of the Catholics burnt. On the other hand, other missions  were relatively peaceful and focused on integration rather than cultural imperialism. The first Catholic Church was built in Beijing in 1650. The emperor granted freedom of religion to Catholics. Ricci had modified the Catholic faith to Chinese thinking, permitting among other things the veneration of the dead. The Vatican disagreed and forbade any adaptation in the so-called Chinese Rites controversy in 1692 and 1742.. What populations were the missionaries made from?
