Here is a timeline of the Khalistan movement:
* 1970s: The Khalistan movement is founded.
* 1984: Indian Prime Minister Indira Gandhi is assassinated by two Sikh bodyguards.
* 1984-1995: The Indian government launches a military operation against Sikh militants in Punjab, resulting in the deaths of thousands of people.
* 1995: The Indian government and Sikh separatists sign an agreement that ends the military operation and promises greater autonomy for Punjab.
* 2012: The Indian Supreme Court rules that the creation of Khalistan is not legally possible.
The Khalistan movement is still active today, and its supporters continue to call for the creation of an independent Sikh state.
