In 1122 what did the treaty of concordance of worms give the church?

The Treaty of Concordat of Worms, signed in 1122, resolved the Investiture Controversy between the papacy and the Holy Roman Empire. It granted the Church the exclusive right to appoint bishops and abbots, thereby reaffirming its spiritual authority. However, the emperor retained the power to invest these appointed leaders with secular authority, creating a balance between ecclesiastical and imperial powers. This agreement marked a significant step in the struggle for autonomy between church and state.
