Separatist movements of Pakistan
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 Pakistani 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.
