Since antiquity, areas around the modern border state of Punjab have seen some of the bloodiest wars and violence (such as Battle of the Hydaspes between Alexander’s Macedonian Army and King Porus), as its plains were the gateway to the fabled 'Hindoostan' for all foreign invaders. It continued so, with the Partition in 1947 when some 18 million people were displaced and moved hastily across the newly drawn borders and an estimated 1-2 million perished (predominantly in ‘Punjab’ of both sides).
It also witnessed some of the fiercest fightings in the Indo-Pak Wars of 1965 and 1971 and remained especially tense in the 1980s at the peak of the Punjab Insurgency.
