Ishak Bey

İshak Bey was the last bey of the İnançid principality of Lâdik around Denizli, succeeding his father Murad Arslan Bey, who died before 1362. A patron of learning like his father, he built a madrasa in Denizli that still bore his name in the sixteenth century.

Around 1368 his small beylik, hard pressed by the Germiyan dynasty, accepted Germiyan overlordship. He was still alive in 1391, when he sold part of his estates to the Ottoman sultan Bayezid I during the latter's campaign at Denizli.
