The date on which Zafar Khán openly threw off his allegiance to Dehli is doubtful. Farishtah says he had the Friday prayer or khutbah repeated in his name after his successful campaign against Jháláváda and Delváda in A.D. 1396. According to the Mirat-i-Sikandari he maintained a nominal allegiance till A.D. 1403 when he formally invested his son Tátár Khán with the sovereignty of Gujarát, under the title of Násir-ud-dín Muhammad Sháh. [Muhammad I. 1403-1404.] On ascending the throne in A.D. 1403, Muhammad Sháh made Asáwal his capital, and, after humbling the chief of Nándod or Nádot in Rájpipla, marched against Dehli by way of Pátan. On his way to Pátan the king sickened and died. His body was brought back to Pátan, and the expedition against Dehli came to nothing. It seems probable that this is a courtly version of the tale; the fact being that in A.D. 1403 Tátár Khán imprisoned his father at Asáwal, and assumed the title of Muhammad Sháh, and that Tátár Khán's death was caused by poison administered in the interest, if not at the suggestion, of his father Zafar Khán. [738] [Zafar Khán reigns as Muzaffar, 1407-1419.] After the death of Muhammad Sháh, Zafar Khán asked his own younger brother Shams Khán Dandáni to carry on the government, but he refused. Zafar Khán accordingly sent Shams Khán Dandáni to Nágor in place of Jalál Khán Khokhar, and in A.D. 1407-8, at Bírpur, at the request of the nobles and chief men of the country, himself formally mounted the throne and assumed the title of Muzaffar Sháh. At this time Álp Khán, son of Diláwar Khán of Málwa, was rumoured to have poisoned his father and ascended the throne with the title of Sultán Hushang Ghori. On hearing this Muzaffar Sháh marched against Hushang and besieged him in Dhár. [739] On reducing Dhár Muzaffar handed Hushang to the charge of his brother Shams Khán, on whom he conferred the title of Nasrat Khán. Hushang remained a year in confinement, and Músa Khán one of his relations usurped his authority. On hearing this, Hushang begged to be released, and Muzaffar Sháh not only agreed to his prayer, but sent his grandson Áhmed Khán with an army to reinstate him. This expedition was successful; the fortress of Mándu was taken and the usurper Músa Khán was put to flight. Áhmed Khán returned to Gujarát in A.D. 1409-10. Meanwhile Muzaffar advancing towards Dehli to aid Sultán Mahmúd (A.D. 1393-1413), prevented an intended attack on that city by Sultán Ibráhím of Jaunpur. On his return to Gujarát Muzaffar led, or more probably despatched, an unsuccessful expedition against Kambhkot. [740] In the following year (A.D. 1410-11), to quell a rising among the Kolis near Asával, Muzaffar placed his grandson Áhmed Khán in command of an army. Áhmed Khán camped outside of Pátan. He convened an assembly of learned men and asked them whether a son was not bound to exact retribution from his father's murderer. The assembly stated in writing that a son was bound to exact retribution. Armed
