Protestant Christianity in the 20th century was characterized by accelerating fragmentation. The century saw the rise of both liberal and conservative splinter groups, as well as a general secularization of Western society. The Roman Catholic Church instituted many reforms in order to modernize. Missionaries also made inroads in the Far East, establishing further followings in China, Taiwan, Korea, and Japan. At the same time, state-promoted atheism in Communist Eastern Europe and the Soviet Union brought many Eastern Orthodox Christians to Western Europe and the United States, leading to greatly increased contact between Western and Eastern Christianity. Nevertheless, church attendance declined more in Western Europe than it did in the East. Christian ecumenism grew in importance, beginning at the Edinburgh Missionary Conference in 1910, and accelerated after the Second Vatican Council (1962–1965) of the Catholic Church, The Liturgical Movement became significant in both Catholic and Protestant Christianity, especially in Anglicanism.
