Gabriel Báthory, Prince of Transylvania (died 1613)

Gabriel Báthory was Prince of Transylvania from 1608 to 1613. The Ottomans nicknamed him "Deli Kiral". Born to the Roman Catholic branch of the Báthory family, he was closely related to four rulers of the Principality of Transylvania. His father, Stephen Báthory, held estates in the principality, but never ruled it. Being a minor when his father died in 1601, Gabriel became the ward of the childless Stephen Báthory, from the Protestant branch of the family, who converted him to Calvinism. After inheriting most of his guardian's estates in 1605, Gabriel became one of the wealthiest landowners in Transylvania and Royal Hungary.
