Speyer, Diet of 1529

Speyer, Diet of (1529)

 

an imperial assembly of the Holy Roman Empire held from March 15 to April 22 in the city of Speyer. The diet adopted measures to halt the spread of the Reformation in Germany. In repealing the decrees of the Diet of Speyer of 1526, the diet proclaimed that the princes and the imperial cities had the right to determine the dominant religion in their holdings, prohibited the further secularization of church property, and affirmed the Edict of Worms of 1521. Some members of the diet were supporters of the Reformation (five princes, including the elector of Saxony and the landgrave of Hesse, and 14 imperial cities); they constituted the so-called Protestation—a protest against the decisions of the majority (hence the Protestants).
