Radu Ilie Haidăul (? – 1558) was the son of Radu of Afumați and ruler of Wallachia from November 15, 1552 to May 1553. The nickname "Haidăul" means hajduk, because having the backing of the Habsburgs in taking over Wallachia, he led an army of mercenaries (known in the Balkan region and the Romanian principalities as "hajduks"), made up of Hungarians and Poles, as well as anti-Ottoman boyars that sought refuge in Transylvania (the latter were hunted down by prince Mircea the Shepherd). * v * t * e
