BEGINNINGS OF THE PROTEST AT SPIRES
In 1526, the Diet of Spires issued an edict granting each member state of the empire religious freedom, which meant that each state was free to adhere to the religion of their choice, including the new wave of reformative thinking inspired by Luther and his associates. In addition to this, the Edict of Spires put a hold on the Edict of Worms issued in 1521, demanding the apprehension of Luther. This edict threatened to break up the spiritual monopoly of Rome and give the reformation a strong and abiding presence within the Empire.
In 1529, Charles the V called for a second Diet to be convened at Spires with the singular purpose of repealing the Edict issued in 1526. The matter appeared to be simple, a single agenda item that could be dealt with quickly and decisively. But in reality, the stakes were extremely high; the religious freedom of the entire Empire and the absolute sovereignty of Rome rested on the decision made by the assembly. Charles himself did not preside over the Diet but sent his brother, Ferdinand of Spain, to do the honors. The diet was formally opened, the business at hand, delineated by Charles in a curt message, read aloud and the tug of war between Catholicism and the Reformation began in earnest. The Papal delegates pushed the case for repeal while the Princes who backed the Reformation rejected the notion, arguing that the principles outlined in the Edict of Spires now made up the constitution of the Empire, having been almost unanimously voted upon by the delegates of the previous Diet.
