Martin Luther's protest of indulgences and other church activities deemed as immoral began with him posting the 95 theses against the established Catholic church(remember that the Great Schism was the divide between Catholic church based in Rome and the Eastern Orthodox church based in Constantinople). The Reformation of the early 1500's further split the Catholic church into people that believed the church should be led from Rome and, ultimately, that god should be accessible to all, not just through the Pope. Lutheranism was formed, named after Martin Luther, and soon after PROTESTantism was coined to encompass a number of those who PROTESTed against the Catholic Church. Soon after you see the rise of Anglicanism in England and Calvinism is the lowlands. This divide in the Christian world would shape many developments both between and within nations of Europe.
