What role of martin Luther play in reformation?

Martin Luther was a pivotal figure in the Protestant Reformation, primarily known for his 95 Theses, which he famously posted on the door of the Wittenberg Castle Church in 1517. His critiques of the Catholic Church, particularly regarding the sale of indulgences and the authority of the Pope, challenged the established religious norms and sparked widespread debate. Luther's translation of The Bible into German made scripture more accessible to the laity, promoting individual interpretation of faith. His actions ultimately led to the establishment of various Protestant denominations and a significant shift in the religious landscape of Europe.
