Duke William V of Bavaria signs a concordat with Pope Gregory XIII,
which gives him the right to tax church property, oversee its
administration, and make some ecclesiastical appointments. In this
way the papacy attempts to ensure the loyalty of secular powers who
might otherwise be tempted by the greater ecclesiastical
sovereignty to be gained from a Protestant church system.
