Why is "Punjab insurgency" trending?

Wikipedia Overview

The Insurgency in Punjab was an armed campaign by the separatists of the Khalistan movement from the mid-1980s to the mid-1990s. Economic and social pressures driven by the Green Revolution prompted calls for Sikh autonomy and separatism. This movement was initially peaceful, but foreign involvement and political pressures drove a heavy handed response from Indian authorities. The demand for a separate Sikh state gained momentum after the Indian Army's Operation Blue Star in 1984 aimed to flush out militants residing in the Golden Temple in Amritsar, a holy site for Sikhs. Terrorism, police brutality and corruption of the authorities greatly exacerbated a tense situation. By the mid-1980s, the movement had evolved into a militant secessionist crisis due to the perceived indifference of the Indian state in regards to mutual negotiations. Eventually, more effective police and military operations, combined with a policy of rapprochement by the Indian government and the election loss of separatist sympathizers in the 1992 Punjab Legislative Assembly election, largely quelled the rebellion by the mid-1990s.
