Samarkand, from the Caspian to the Ganges, his authority was acknowledged. The wealth brought back to Ghazni was enormous, and contemporary historians give glowing descriptions of the magnificence of the capital, as well as of the conqueror's munificent support of literature. Mahmud died in 1030, and some fourteen kings of his house came after him; but though there was some revival of importance under Ibrahim (1059-1099), the empire never reached anything like the same splendour and power. It was overshadowed by the Seljuks of Persia, and by the rising rivalry of Ghor (q.v.), the hostility of which it had repeatedly provoked. Bahram Shah (1118-1152) put to death Kutbuddin, one of the princes of Ghor, called king of the Jibal or Hill country, who had withdrawn to Ghazni. This prince's brother, Saifuddin Suri, came to take vengeance, and drove out Bahram. But the latter recapturing the place (1149) paraded Saifuddin and his vizier ignominiously about the city, and then hanged them on the bridge. Ala-uddin of Ghor, younger brother of the two slain princes, then gathered a great host, and came against Bahram, who met him on the Helmund. The Ghori prince, after repeated victories, stormed Ghazni, and gave it over to fire and sword. The dead kings of the house of Mahmud, except the conqueror himself and two others, were torn from their graves and burnt, whilst the bodies of the princes of Ghor were solemnly disinterred and carried to the distant tombs of their ancestors. It seems certain that Ghazni never recovered the splendour that perished then (1152). Ala-uddin, who from this deed became known in history as _Jah[=an]-soz_ (_Brûlemonde_), returned to Ghor, and Bahram reoccupied Ghazni; he died in 1157. In the time of his son Khusru Shah, Ghazni was taken by the Turkish tribes called Ghuzz (generally believed to have been what are now called Turkomans). The king fled to Lahore, and the dynasty ended with his son. In 1173 the Ghuzz were expelled by Ghiyasuddin sultan of Ghor (nephew of Ala-uddin Jahansoz), who made Ghazni over to his brother Muizuddin. This famous prince, whom the later historians call Mahommed Ghori, shortly afterwards (1174-1175) invaded India, taking Multan and Uchh. This was the first of many successive inroads on western and northern India, in one of which Lahore was wrested from Khusru Malik, the last of Mahmud's house, who died a captive in the hills of Ghor. In 1192 Prithvi Rai or Pithora (as the Moslem writers call him), the Chauhan king of Ajmere, being defeated and slain near Thanewar, the whole country from the Himalaya to Ajmere became subject to the Ghori king of Ghazni. On the death of his brother Ghiyasuddin, with whose power he had been constantly associated, and of whose conquests he had been the chief instrument, Muizuddin became sole sovereign over Ghor and Ghazni, and the latter place was then again for a brief period the seat of an empire nearly as extensive as that of Mahmud the son of Sabuktagin.
