John Hunyadi
Corvin Castle was laid out in 1446, when construction began on the orders of Voivode of Transylvania John Hunyadi (, ) who wanted to transform the former keep built by Charles I of Hungary. The castle was originally given to John Hunyadi's father, Voyk (Vajk), by Sigismund of Luxembourg, king of Hungary and Croatia, as severance in 1409. It was also in 1446 that John Hunyadi was elected as the regent-governor by the Diet.
