The 500th Anniversary of the Protestant Reformation was celebrated in 2017, marking 500 years since Martin Luther famously posted his Ninety-Five Theses in 1517. This act challenged the practices of the Catholic Church, particularly the sale of indulgences, and sparked a movement that led to the establishment of various Protestant denominations. The Reformation significantly changed the religious landscape in Europe and influenced social, political, and cultural developments. It emphasized individual faith and the authority of the Bible, leading to a greater focus on personal interpretation of scripture and the rise of religious pluralism.
