[Fírúz Tughlak Emperor, 1351-1388.] In A.D. 1351, Fírúz Tughlak succeeded Muhammad Tughlak on the throne of Dehli. Shortly after his accession the emperor marched to Sindh and sent a force against Malik Túghán. About A.D. 1360 he again advanced to Sindh against Jám Bábunia. From Sindh he proceeded to Gujarát, where he stayed for some months. [Zafar Khan Governor, 1371.] Next year, on leaving for Sindh for the third time, he bestowed the government of Gujarát on Zafar Khán in place of Nizám-ul-Mulk. On Zafar Khán's death, in A.D. 1373 according to Farishtah and A.D. 1371 according to the Mirat-i-Áhmedi, he was succeeded by his son Daryá Khán who appears to have governed by a deputy named Shams-ud-dín Anwar Khán. In A.D. 1376, besides presents of elephants horses and other valuables, one Shams-ud-dín Dámghání offered a considerable advance on the usual collections from Gujarát. As Daryá Khán would not agree to pay this sum he was displaced and Shams-ud-dín Dámghání was appointed governor. Finding himself unable to pay the stipulated amount this officer rebelled and withheld the revenue. Fírúz Tughlak sent an army against him, and by the aid of the chieftains and people, whom he had greatly oppressed, Shams-ud-dín was slain. The government of the province was then entrusted to Farhat-ul-Mulk Rásti Khán. [Farhat-ul-Mulk Governor, 1376-1391.] In about A.D. 1388, a noble named Sikandar Khán was sent to supersede Farhat-ul-Mulk, but was defeated and slain by him. As the emperor Fírúz Tughlak died shortly after no notice was taken of Farhat-ul-Mulk's conduct and in the short reign of Fírúz's successor Ghiás-ud-dín Tughlak, no change was made in the government of Gujarát. During the brief rule of Abu Bakr, Farhat-ul-Mulk continued undisturbed. [Muhammad Tughlak II. Emperor, 1391-1393.] But in A.D. 1391, on the accession of Násir-ud-dín Muhammad Tughlak II., a noble of the name of Zafar Khán was appointed governor of Gujarát, and despatched with an army to recall or, if necessary, expel Farhat-ul-Mulk.
