The subjugation of such districts could only be by a system of effective military occupation and would be a work of time; but Alexander made a beginning by punitive expeditions, as occasion offered, calculated to reduce the free tribes to temporary quiet; we hear of such expeditions in the case of the Pisidians, the tribes of the Lebanon, the Uxii (in Khuzistan), the Tapyri (in the Elburz), the hill-peoples of Bajaor and Swat, the Cossaei (in Kurdistan); an expedition against the Arabs was in preparation when Alexander died.

This prince maintained himself in power till the year 900, when he was beaten and taken prisoner by Isma`il b.
Nasir was very ambitious; he had added Khuzistan to his dominions, and desired to become also master of Media (Jabal, or Persian Irak, as it was called in the time of the Seljuks).
