There are or have been a number of separatist movements in Pakistan based on ethnic and regional nationalism, that have agitated for independence, and sometimes fighting the Pakistan state at various times during its history. As in many other countries, tension arises from the perception of minority/less powerful ethnic groups that other ethnicities dominate the politics and economics of the country to the detriment of those with less power and money. The government of Pakistan has attempted to subdue these separatist movements, which have included those in Bangladesh, the Baloch Liberation Front (BLF) in Balochistan; the "Sindhudesh" movement in Sindh province; "Balawaristan" in Gilgit-Baltistan; Jinnahpur and Muhajir Sooba movement for muhajir immigrants from India.
Influence and success of separatist groups has varied from total, in the case of Bangladesh, which separated from Pakistan in 1971, to marginal, as in the case of the Mohajir Qaumi Movement, which when accused by Pakistani intelligence of wanting an independent state, claimed to only want more autonomy.
Separatist sentiment by opinion poll
The separatist movement in Balochistan is engaged in a low-intensity insurgency against the Government of Pakistan.
In 2009, the Pew Research Center conducted a Global Attitudes survey across Pakistan, in which it questioned respondents whether they viewed their primary identity as Pakistani or that of their ethnicity. The sample covered an area representing 90% of the adult population, and included all major ethnic groups. According to the findings, 96% of Punjabis identified themselves first as Pakistanis, as did 92% each of Pashtuns and Muhajirs; 55% of Sindhis chose a Pakistani identification, while 28% chose Sindhi and 16% selected "both equally"; whereas 58% of Baloch respondents chose Pakistani and 32% selected their ethnicity and 10% chose both equally. Collectively, 89% of the sample opted their primary identity as Pakistani. Similarly in 2010, Chatham House conducted an opinion poll in the Pakistani and Indian-administered regions of Kashmir asking respondents if they favoured independence or an accession to either countries; in Azad Kashmir controlled by Pakistan, 50% of respondents voted to join Pakistan, 44% voted for independence, and only 1% voted for accession to India. In the northern region of Gilgit-Baltistan, longstanding local sentiments oppose any merger of the area with Kashmir, and instead demand a constitutional integration with Pakistan.
Bangladesh
Pakistan was established in 1947, from the partition, as a state for Muslims. Its formation was based on the basis of Islamic nationalism.
As part of the Partition of India in 1947, Bengal was partitioned between the Dominion of India and the Dominion of Pakistan. The Pakistani part of Bengal was known as East Bengal until 1955 and thereafter as East-Pakistan following the implementation of the One Unit program. However, rampant corruption within the ranks of the Pakistani government and bureaucracy, economic inequality between the country's two wings caused mainly by a lack of representative government and the government's indifference to the efforts of fierce ethno-nationalistic politicians, like Sheik Mujibur Rahman from East Pakistan, who fought for Bangladeshi independence, resulted in civil war in Pakistan and subsequent separation of East Pakistan as the People's Republic of Bangladesh. Bilateral relations between the two wings grew strained over the lack of official recognition for the Bengali language, democracy, regional autonomy, disparity between the two wings, ethnic discrimination, and the central government's weak and inefficient relief efforts after the 1970 Bhola cyclone, which had affected millions in East Pakistan. These grievances led to several political agitations in East Bengal and ultimately a fight for full independence, which was made possible in 1971 with the assistance of the Indian military.
