Shortly afterwards Balochistan fell to Nasir-ud-din Sabuktagin, Sabuktagin's son Mahmud of Ghazni was able to conquer Sindh due to his possession of Khuzdar. After the Ghaznivids the area passed to the Ghurids and a little later became part of the dominion of Sultan Muhammad Khan of Khwazrizm (Khiva) in 1219.^[10] However around 1223 a Mongol expedition under Chagatai, the son of Genghis Khan, penetrated as far as Makran. A few years later, southern Baluchistan briefly came under the rule of Sultan Altamsh of Delhi but soon came back under Mongol rule. The raids organised by the Mongols have left a lasting mark on history of Baluchistan, from Makran to Gomal the Mongol (known to the people as Mughal) and the atrocities they caused are still well known.^[10]
Afterwards the history of Balochistan centres around Kandahar and is was in this area in 1398 that Pir Muhammad, the grandson of Timur, fought the Afghans in the Sulaiman mountains. According to local tradition Timur himself passed through Marri country during one of his Indian expeditions.^[10]
The succeeding century is one of great historical interest. The Baloch extended their power to Kalat, Kachhi, and the Punjab, and the wars took place between Mir Chakar the Rind and Gwahram Lashari which are so celebrated in Baloch verse. In these wars a prominent part was played by Mir Zunnun Beg, Arghun, who was governor of north-eastern Baluchistan under Sultan Husain Mirza of Herat about 1470. At the same time the Brahuis had been gradually gaining strength, and their little principality at this time extended through the Jhalawan country to Wadh.^[17]
The Arghuns shortly afterwards gave way before Babar. From 1556 to 1595 the country was under the Safavid dynasty. Then it fell into the hands of the Mughals of Delhi until 1638, when it was again transferred to Persia. We have an interesting account of Baluchistan in the Ain-i-Akbari. In 1590 the upper highlands were included in the sarkdr of Kandahar, while Kachhi was part of the Bhakkar sarkdr of the Multan Subah. Makrdn alone remained independent under the Maliks, Buledais, and Gichkis, until Nasir Khan I of Kalat brought it within his power during the 18th century.^[17]
From the middle of the 17th century Baluchistan remained under the Safavids till the rise of the Ghilzai power in I708. The latter in its turn gave way before Nadir Shah, who, during the first part of the 18th century, made several expeditions to or through Baluchistan. Ahmad Shah Durrani followed; and thenceforth the north-eastern part of the country, including almost all the areas now under direct administration, remained under the more or less nominal suzerainty of the Sadozais and Barakzais till I879, when Pishin, Duki, and Sibi passed into British hands by the Treaty of Gandamak. Meanwhile the whole of Western Baluchistan had been consolidated into an organized state under the Ahmadzai Khans of Kalat. All tradition asserts that the former rulers of Kalat were Hindus, Sewa by name.^[17]
As Muslim dynasties held Baluchistan from about the 7th century, we must look to an earlier period for the date of the Sewas; and it is not improbable that they were connected with the Rai dynasty of Sind, whose genealogical table includes two rulers named Sihras. The Mirwaris, from whom the Ahmadzais are descended, claim Arab origin. In their earlier legends we find them living at Surab near Kalat, and extending their power thence in wars with the Jats or Jadgals. They then fell under the power of the Mongols; but one of their chiefs, Mir Hasan, regained the capital from the Mongol governor, and he and his successors held Kalat for twelve generations till the rise of Mir Ahmad in 1666-7. It is from Mir Ahmad that the eponym Ahmadzai is derived.
