Bihar was an administrative county (comitatus) of the Kingdom of Hungary and a county of the Eastern Hungarian Kingdom and Principality of Transylvania (since the 16th century, when it was under the rule of the Princes of Transylvania). Most of its territory is now part of Romania, while a smaller western part belongs to Hungary. The capital of the county was Nagyvárad (now Oradea in Romania). Albrecht Dürer's father was from this county.
