The Felician Charter, an important ecclesiastical document, is largely credited with the first official mention of the city of Zagreb around 1094. This charter was created during a period when the region was undergoing significant changes in governance and religious structure influenced by the Catholic Church. It was instrumental in the formation of the Zagreb Bishopric, an essential institution that would play a central role in the spiritual life of the community and the region at large.

During this period, the consolidation of church authority was pivotal. The establishment of the bishopric not only provided a spiritual leader for the populace but also influenced local governance. The Felician Charter served as a regulatory framework for the bishop's jurisdiction, outlining the responsibilities and powers vested in this ecclesiastical position. It is noteworthy that this charter helped to define Zagreb’s position within the broader context of medieval Christendom, linking it to the religious and political currents of the time.

Furthermore, the emergence of Zagreb as a bishopric facilitated interactions with other regions, promoting trade, culture, and the spread of knowledge within the area. Over time, this would contribute to Zagreb's development as a center of secular and religious power, shaping its identity that would last for centuries. In this way, the Felician Charter not only signifies the historical roots of Zagreb but also lays the groundwork for its future prominence in the region.
