Diet of Speyer of 1526

The Diet of Speyer or the Diet of Spires (sometimes referred to as Speyer I) was an Imperial Diet of the Holy Roman Empire in 1526 in the Imperial City of Speyer in present-day Germany. The diet's ambiguous edict resulted in a temporary suspension of the Edict of Worms and aided the expansion of Protestantism. These results were repudiated in the Diet of Speyer of 1529.
