Concordat of Worms
The First Lateran Council was convoked to confirm the Concordat of Worms. The council was most representative with nearly three hundred bishops and six hundred abbots from every part of Catholic Europe being present. It convened on March 18, 1123. Decrees were also passed directed against simony, concubinage among the clergy, church robbers, and forgers of Church documents; the council also reaffirmed indulgences for Crusaders.
