Martin Luther was a German friar and theologist who started the Protestant Reformation movement against the Roman Catholic Church. Luther was outraged by the Roman Catholic church's political involvement, materialism, corruption, and sale of indulgences. He wanted Catholicism to be more individual and more accessible, and as such wanted the bible translated into vernacular languages and priests to be educated and able to interpret the bible rather than just read it. He also opposed the seven sacraments as the basis of salvation, thinking that it should instead be based on morality. Luther's followers, the Lutherans, were especially prominent in the Holy Roman Empire, and various sects of radical reformers formed, including Lutherans, Anglicans, Anabaptists, and Calvinists.
