compiled tlie Tarikh-i-Yamini. was made Wazir. Kabus the son of Wasli- 
mgir was made, or rather recognized, as governor in Gnrgan, and others 
in outlying provinces, but in most cases such governors were practically 
independent. Tash the Hajib was despatched against ’Uzd-ud-daulah 
the Buwiah who ruled both the ’Iraks, but defeated. Not long after 
both Tash and Simjur themselves revolted, although after some strug¬ 
gles both returned to their allegiance, and Abu ’All the son of the latter 
was given the command of the Amir’s troops. Abu ’Ali turned out in 
every way even a baser man than his father, for he had no sooner entered 
the service than he commenced intriguing against Niih. 
On the eastern frontier of the kingdom a new power had for some 
time been growing, in the shape of the Khanate of Turkistan. Regard¬ 
ing the earlier of these Turkistan Khans but little is known, and that 
little to a great extent unreliable. Of Tlaks and Bughras and Arsalans 
there are at least two or three of each casually mentioned by Muhamma¬ 
dan historians, with a considerable amount of uncertainty as to their iden¬ 
tity, and possibly the same man is occasionally made to do duty for two 
separate chiefs. The first who became a convert to Islam is said to have 
been Satiik-Kujah, or Satuk Karachar, who endeavoured to extend the 
belief among his people, probably about 315 or 320 H. On his death, 
his son Miisa succeeded, and after Musa his grandson Abii Nasr-i- 
Ahmad, bin ’Ali, bin Musa, under the title of the IlaJc Khan, the title of 
riak by some being held to be the ruler of a tribe, or a leader, subor¬ 
dinate to a Khan. This flak bore the Musalman title of Shams-ud-daulah, 
and is presumably the one who entered Marwara-un-Nahr from Turkis¬ 
tan in 367. The fourth was the grandson, Abu Miisa-i-Harun 
Bughra Khan bin Suliman bin ITak, and though it is probably his suc¬ 
cessor, the more famous Ilak, who really completed the uniting and con¬ 
solidating the scattered Turkish States from the Eastern frontier of 
Khokand to the modern Chinese province of Kansu, Bu gh ra Khan had 
nevertheless already become celebrated both as a powerful ruler and for 
his successful religious wars in the cause of Islam, He had united all 
the Eastern Turkish tribes under his sceptre and was now pushing his 
conquests westwards, thinking to enrich himself with some fragments 
of the decaying Samani empire. Ignoring the puppet Amir, and ad¬ 
dressing himself to the rebellious Abu ’Ali he entered Mawara-un-Nahr 
from Kash gh ar his capital, for the first time in 372 H., and subsequently 
in communication with Fayik and Abii. ’Ali with the latter of whom 
he had a secret treaty to divide the country, invaded in force in 380 H. 
The Samani forces were beaten on one or two occasions, the ablest 
of their generals, Madawanj, being defeated near Samarkand. The rebel¬ 
lious Fayik would seem to have been then put at the head of the army,
