An agreement between the papacy and a state

The Concordat Was A Failure

This is actually a phrase, not a question, but the concordat of 1801 was an agreement between Napoleon Bonaparte and Pope Pius VII. The govt recognized the influence of the Church, but did not give it power. the govt would also pay the clergy and pick the archbishops and bishops

The root word of concordat is "concord," which means agreement or harmony.

A concordat was agreed between Church and State on a matter of mutual interest
