Elections were held in Punjab in February 1992 with the Akali Dal boycotting and turnout below a quarter. Beant Singh became Chief Minister.
The counter-insurgency was brought to a conclusion during his term, under a police leadership given extensive latitude. The violence ended. What was done to end it has been documented by human rights bodies as including large numbers of disappearances and unacknowledged killings, and has never been examined in any comprehensive public process.
On 31 August 1995 Beant Singh was killed by a suicide bomber outside the Punjab Civil Secretariat at Chandigarh, along with sixteen others.
Elections in 1997 returned the Akali Dal and the Bharatiya Janata Party with a large majority and the state returned to normal politics.
Punjab has been at peace since. The accounting for how that was achieved has not happened, and the families of the disappeared are still filing cases.
This page states the sequence and the documented findings and does not resolve the argument, because no process has.
He was chief minister from 1992, elected in a poll that most parties boycotted and in which turnout was very low, and he was killed by a bomb outside the secretariat in Chandigarh in August 1995.
The period of his government is when the militancy was ended, by police methods that produced the disappearances case and the human rights proceedings that followed.
Both facts belong to the same decade and both are stated here. What that decade cost, and who it was taken from, is the argument Punjab has not finished having.
