# Diet of Worms

> Martin Luther defied Emperor Charles V and papal authority, cementing the Protestant Reformation and fracturing Western Christian unity permanently.

In April 1521, Holy Roman Emperor Charles V summoned Martin Luther to the German city of Worms to defend his religious writings before the imperial court. Luther's refusal to recant his critiques of the Catholic Church became a defining moment for the Protestant Reformation, effectively splitting Western Christianity.

## Summary

The Diet of Worms of 1521 was an imperial diet of the Holy Roman Empire called by Emperor Charles V and conducted in the Imperial Free City of Worms. Martin Luther was summoned to the diet in order to renounce or reaffirm his views in response to a Papal bull of Pope Leo X. In answer to questioning, he defended the views that had been criticized and refused to recant them. At the end of the diet, the Emperor issued the Edict of Worms, a decree which condemned Luther as "a notorious heretic" and banned citizens of the Empire from propagating his ideas. Although the Reformation is usually considered to have begun in 1517, this edict is the first overt schism associated with it.
