The present state system in South Asia, in particular the state system of the sub-continent, is a result largely of the partitions in the eastern and western parts of the erstwhile united India, giving birth to three states – India, Pakistan, and Bangladesh. The borders dividing these countries are markers of past bitter history, current separate, distinct, and independent existence, and the sign of the territorial integrity of these states. The bitterness of the past has been exacerbated by the lack of mutual confidence at present. This makes migration across these borders extremely contentious. There is another added dimension to the borders and that is the existence of thousand and one linkages across these borders that make the South Asian borders and migration across it as a unique phenomenon. South Asian borders then are lines of hatred, disunity, informal connections and voluminous informal trade, securitised and militarized lines, heavy para-military presence, communal discord, humanitarian crisis, human rights abuses, and enormous suspicion resulting in making migration a violent affair. Yet migration across these borders never stops.
