Rebaptism Made a Capital Crime

The same Diet of Speyer that gave Protestants their name revived an ancient Roman law against rebaptism and decreed death for Anabaptists, to be carried out by the secular courts. Catholic and Lutheran rulers alike agreed. Believers who baptized only on profession of faith were drowned, burned, and beheaded across the empire.

Background

An Empire Divided Over the Gospel

By 1529 the Holy Roman Empire had been arguing about Martin Luther for more than a decade. At Worms in 1521 the young Emperor Charles V had declared Luther an outlaw and banned his writings, but the edict proved impossible to enforce. Charles was often away, fighting France in Italy and facing the Ottoman Turks, who had crushed Hungary at Mohács in 1526 and were advancing toward Vienna. German princes and cities who favored the Reformation used his distraction.

At the first Diet of Speyer, in 1526, the estates agreed that until a general council met, each ruler should act in matters of religion as he could answer to God and the emperor. Evangelical princes took that as permission to reform the churches of their territories, and many did. In 1529 the emperor, acting through his brother Archduke Ferdinand, summoned a second diet to Speyer to undo the damage. The Catholic estates held a clear majority.

A diet, not a council

A diet was an assembly of the empire's princes, prince-bishops, and free cities meeting with the emperor or his representative, and it made law for the empire. At Speyer in 1529 Catholic and evangelical rulers sat together. What divided them made the diet famous; what united them is the subject of this article.
