What was the effect of Luther's 95 posts?

Luther's 95 Theses sparked the Protestant Reformation by challenging the Catholic Church's practices, particularly the sale of indulgences. His ideas spread rapidly due to the printing press, leading to widespread debate and reform. This movement resulted in the fragmentation of Christianity in Western Europe, the establishment of Protestant denominations, and significant theological and political changes. Ultimately, Luther's actions encouraged greater scrutiny of church authority and promoted individual interpretation of scripture.
