Origins
Kalat, a town on the high plateau of central Balochistan, became the seat of a Brahui-speaking ruling family, the Ahmadzai, in the later seventeenth century; Mir Ahmad, from whom the dynasty takes its name, is usually dated from 1666. The khans headed a confederacy of Baloch and Brahui tribes, whose chiefs, the sardars, held their own lands and armed followers. The khanate stood between the Safavid and Mughal empires and later between Iran and the Afghan state.
Nasir Khan
Mir Nasir Khan I, who ruled for about half a century from around 1749, made Kalat a significant power. He organised the tribes into two wings for military service, extended his rule to the coast of Makran and to the plains of Kachhi, and acknowledged the overlordship of Ahmad Shah Durrani, whom he accompanied on campaigns in India, including, by most accounts, at Panipat in 1761. After a dispute with Ahmad Shah he obtained a treaty recognising Kalat's near independence. He is remembered in Baloch tradition as Nasir Khan the Great.
The British protectorate
In 1839, during the First Anglo-Afghan War, a British army passing through Balochistan stormed Kalat, and the khan, Mehrab Khan, was killed. Later treaties, in 1841 and 1854, bound Kalat to British India. In 1876 the political officer Robert Sandeman negotiated the treaty of Mastung, which settled a dispute between the khan and his sardars with British mediation and made Kalat a protectorate. The British leased Quetta from the khan in 1883 and built it into a military base, and Balochistan was administered as an agency under a British agent to the governor-general.
Accession
As British rule ended, the khan, Mir Ahmad Yar Khan, claimed that Kalat had a treaty relationship with Britain separate from the princely states of India and declared independence on 15 August 1947, a claim that Muhammad Ali Jinnah, who had earlier acted as the khan's legal adviser, at first appeared to accept. Pakistan pressed for accession, and the neighbouring states of Kharan, Las Bela and Makran acceded separately. On 27 March 1948 the khan signed the instrument of accession to Pakistan. His brother, Prince Abdul Karim, led an armed revolt against the accession, the first of several Baloch insurgencies.
Kalat was merged with the other Baloch states into the Baluchistan States Union in 1952, and in 1955 into West Pakistan. The accession remains a grievance in Baloch nationalist politics.
