The Diet of Worms was a pivotal imperial assembly, not a biological experiment.

In short: When Martin Luther was summoned to the 1521 Diet of Worms, he faced the Holy Roman Empire’s highest authority. Despite the name, this was a formal political and religious meeting in Germany, not a study of invertebrates. It became the definitive moment that split Western Christendom into permanent factions.

The Diet of Worms was a formal deliberative assembly of the Holy Roman Empire, convened in 1521 in the Imperial Free City of Worms, Germany. It was presided over by Emperor Charles V to address the growing religious crisis ignited by Martin Luther. Luther, a German theologian who had been excommunicated by Pope Leo X earlier that year, was summoned to answer for his writings, which were condemned as heretical. The stakes were immense, as the assembly served as the stage for the first overt schism of the Protestant Reformation.

Luther’s appearance on April 17 and 18, 1521, remains one of history’s most famous confrontations. Represented by his lawyer Jerome Schurff, Luther was asked to renounce his works, which included his Ninety-five Theses and various treatises on the papacy. Rather than recanting, Luther famously asserted that his conscience was captive to the Word of God, arguing that neither popes nor councils were infallible. He refused to reject his teachings unless convinced by Scripture or clear reason, effectively challenging the absolute authority of the Church.

The assembly concluded with the Edict of Worms, which branded Luther a notorious heretic and outlaw, banning the propagation of his ideas throughout the Empire. While the term 'Diet of Worms' is synonymous with this 1521 event, the city hosted other imperial diets throughout history, including meetings in 829, 1076, and 1495. Today, the name is distinct from artistic explorations of actual worms, such as Kiki Smith’s 1992 collage or Francisco Toledo’s 2013 felt textile work, which use the creature as a metaphor for decay or artistic process.
