Protestantism is one of the major groupings within Christianity. It has been defined as "any of several church denominations denying the universal authority of the Pope and affirming the Reformation principles of justification by faith alone, the priesthood of all believers, and the primacy of the Bible as the only source of revealed truth" and, more broadly, to mean Christianity outside "of a Catholic or Eastern church". It is a movement that began in Germany in the early 16th century as a reaction against medieval Roman Catholic doctrines and practices, especially in regard to salvation, justification, and ecclesiology. The doctrines of the over 33,000 Protestant denominations vary, but most include justification by grace through faith alone, known as Sola Gratia and Sola Fide respectively, the priesthood of all believers, and the Bible as the supreme authority in matters of faith and morals, known as Sola Scriptura, Latinfor "by scripture alone".
In the 20th century, Protestantism, especially in the United States, 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. Notable developments in the 20th century of US Protestantism was the rise of Pentecostalism, Christian fundamentalism and Evangelicalism. While these movements have spilled over to Europe to a limited degree, the development of Protestantism in Europe was more dominated by secularization, leading to an increasingly "post-Christian Europe".
There are about 800 million Protestants worldwide, among approximately 2.1 billion Christians. These include 170 million in North America, 160 million in Africa, 120 million in Europe, 70 million in Latin America, 60 million in Asia, and 10 million in Oceania. Main denominational families:
