So far, there were five waves of insurgencies. After the 1948 rebellion was put down, crisis erupted in 1958.
In 1962-63 and 1973-77, there were violent campaigns by the Baloch nationalists for independence from Pakistan.
The two decades after that was the calmest period in the history of Balochistan.
But tensions started building up after General Pervez Musharraf seized power in 1999. When the military started building new cantonments in Balochistan, it was seen by radical nationalist factions as a bid by the Army to tighten control over the region.
The fifth wave of insurgency that broke out in this context is still on. There are several separatist groups in the province.
The strongest among them is the Balochistan Liberation Army (BLA), designated as a terrorist group by Pakistan and the U.K.
