In the 10th/16th century Isma'il, who was of the household of Shaykh Safi al-Din Ardibili (d. 735/1334), a Sufi master and also a Shi'ite, began a revolt in Ardibil, with three hundred Sufis who were disciples of his forefathers, with the aim of establishing an independent and powerful Shi'ite country. In this way he began the conquest of Persia and overcame the local feudal princes. After a series of bloody wars with local rulers and also the Ottomans who held the title of caliph, he succeeded in forming Persia piece by piece into a country and in making Shi'ism the official religion in his kingdom.
