The Reformation was a groundbreaking religious movement in the 16th century that forever changed Christianity in Europe. One of the most important figures in this movement was Martin Luther, a German monk and professor of theology. This paper explores Luther’s early life, the reasons behind his protest against the Catholic Church, the significance of his Ninety-Five Theses, and how his ideas influenced religious and political structures across Europe. Through his writings, teachings, and actions, Martin Luther not only challenged the authority of the Catholic Church but also laid the foundation for Protestant Christianity and modern democratic values.
