Archdiocese of Esztergom

The archbishopric of Esztergom (or archbishopric of Gran) was the most prominent historical archdiocese in (Austro-)Hungary.

It was created in 1000 under Stephen I of Hungary largely on the territory of Upper Hungary. After the Treaty of Trianon in 1920, its territory was reduced to its present-day extent; it became the Archdiocese of Esztergom-Budapest on 31 May 1993. The rest became part of the Catholic structures of Czechoslovakia (now Slovakia).
