Question

What did the concordat of worms do

Answer 1

The Concordat of Worms, sometimes called the Pactum Calixtinum by papal historians, was an agreement between Pope Calixtus II and Holy Roman Emperor Henry V on September 23, 1122 near the city of Worms. It brought to an end the first phase of the power struggle between the Papacy and the Holy Roman Emperors. The King was recognized as having the right to invest bishops with secular authority ("by the lance") in the territories they governed, but not with sacred authority ("by ring and staff").
