Archbishopric of Mainz

The Archbishopric of Mainz was a significant ecclesiastical territory in the Holy Roman Empire, led by the Archbishop of Mainz. It served both as a religious authority and a political power, overseeing Christian church affairs and acting as a prince within the empire. The Archbishop of Mainz was one of the seven Prince-Electors responsible for choosing the Holy Roman Emperor. Historically, Mainz was an important cultural and spiritual center, known for its cathedral and influence in medieval Europe. The archbishopric played a key role in church governance, regional politics, and imperial elections until its dissolution in the early 19th century.
