Mercurius of Transylvania
12th-century Voivode of Transylvania
Mercurius (Hungarian: Merkúr)[1] was a Hungarian distinguished nobleman and perhaps the first known voivode of Transylvania, who held the office during the reign of Coloman, King of Hungary.[1] Two royal charters issued in 1111 and 1113 mention Mercurius as "princeps Ultrasilvanus", but he may have been only an important landowner in Transylvania without holding any specific office.[2] The title voivode was first documented[where?] specifically in 1199.[3]
A source from 1097[which?] also mentions a "Mercurio comes Bellegratae", which means "count (ispán) of Fehér", and this record may point to the same person.[2][4][5]
