The Diet of Worms convened in 1521, presided over by Holy Roman Emperor Charles V, where Martin Luther famously refused to recant his 95 Theses. This pivotal moment in the Protestant Reformation resulted in Luther being declared an outlaw, solidifying the divide between Catholicism and emerging Protestant beliefs. The Diet underscored the growing tensions between religious authority and individual conscience, influencing the course of European history and the development of modern religious thought.

Martin Luther's defiance at the Diet of Worms not only marked a pivotal moment in religious history but also inspired poets like Heinrich Heine and John Milton to grapple with themes of individual conscience and rebellion. Their works echoed Luther's spirit, emphasizing the importance of personal belief and the courage to challenge authority.
