Dagome Iudex

The Dagome Iudex is an important medieval document from 1138 in which Duke Mieszko III of Poland dedicated his domain to the Catholic Church, specifically to the Pope. This act effectively placed his territory under papal protection and established the church's influence over Polish lands. It also defined boundaries of the duchy and granted substantial rights to the church, shaping Poland's political and religious structure. The document is a key historical record showing the close relationship between Polish rulers and the church during that period.
