Ṣadaqa Beg (Turkish: Sadaka Bey) was the fourth ruler of the Turkoman Dulkadirid principality, ruling from 1398 to 1399. He rose to the throne after his father Sūlī Beg was assassinated and the Mamluks issued him the manshūr, the diploma to rule.^[1] However, Ṣadaqa was quickly deposed and forced out of Elbistan by the Ottoman Sultan Bayezid I, who allowed Ṣadaqa's cousin and rival Mehmed to be the new ruler.^[2][1]
