History
Mehrgarh, at the foot of the Bolan Pass, is one of the earliest farming settlements in South Asia and a forerunner of the Indus Valley Civilisation. The region lay on the fringes of Persian empires, and in 325 BC Alexander the Great led part of his army back from India across the Gedrosian desert of the Makran, losing many men to thirst and heat. Arab armies passed through on their way to Sindh in the early 8th century.
The Baloch, speakers of an Iranian language, spread through the region in the medieval period alongside the Brahui, whose language is Dravidian. From the 17th century the Khanate of Kalat united many tribes, reaching its height under Nasir Khan I in the 18th century. The British, securing routes to Afghanistan, took Quetta and the Bolan Pass in the 19th century and made Quetta a garrison town; an earthquake destroyed it in 1935, killing tens of thousands.
Kalat's accession to Pakistan in 1948 was disputed from the start, and Baloch nationalists have rebelled several times since, most seriously in the 1970s and again since the early 2000s, especially after the army killed the tribal leader Nawab Akbar Bugti in 2006. Pakistan bought Gwadar from Oman in 1958 and tested its nuclear weapons in the Chagai hills in 1998. Chinese investment in Gwadar port under the China–Pakistan Economic Corridor has sharpened Baloch grievances over who benefits from the province's gas and minerals, and enforced disappearances of activists are a major issue.
