Problem: In the early 1980s, a small but vocal segment of anthropologists and archaeologists attempted to demonstrate that contemporary groups usually identified as hunter-gatherers do not, in most cases, have a continuous history of hunting and gathering, and that in many cases their ancestors were agriculturalists and/or pastoralists[citation needed] who were pushed into marginal areas as a result of migrations, economic exploitation, and/or violent conflict (see, for example, the Kalahari Debate). The result of their effort has been the general acknowledgement that there has been complex interaction between hunter-gatherers and non-hunter-gatherers for millennia.[citation needed]
Besides economic troubles, what else could push a people into foraging?
The answer is the following: violent conflict

Input: Punjab, Pakistan
The Punjabis followed a diverse plethora of faiths, mainly comprising Hinduism[citation needed] , when the Muslim Umayyad army led by Muhammad bin Qasim conquered Sindh and Southern Punjab in 712, by defeating Raja Dahir. The Umayyad Caliphate was the second Islamic caliphate established after the death of Muhammad. It was ruled by the Umayyad dynasty, whose name derives from Umayya ibn Abd Shams, the great-grandfather of the first Umayyad caliph. Although the Umayyad family originally came from the city of Mecca, their capital was Damascus. Muhammad bin Qasim was the first to bring message of Islam to the population of Punjab.[citation needed] Punjab was part of different Muslim Empires consisting of Afghans and Turkic peoples in co-operation with local Punjabi tribes and others.[citation needed] In the 11th century, during the reign of Mahmud of Ghazni, the province became an important centre with Lahore as its second capital[citation needed] of the Ghaznavid Empire based out of Afghanistan. The Punjab region became predominantly Muslim due to missionary Sufi saints whose dargahs dot the landscape of Punjab region.
