The accord was signed on 24 July 1985 between Prime Minister Rajiv Gandhi and Sant Harchand Singh Longowal, president of the Akali Dal.
It provided for the transfer of Chandigarh to Punjab by January 1986; a commission to determine the Hindi-speaking areas to be transferred to Haryana in exchange; a tribunal on river waters; an inquiry into the November 1984 killings; and rehabilitation of those affected by the violence.
Longowal was shot dead in a gurdwara at Sherpur in Sangrur district on 20 August 1985, twenty-seven days later.
Chandigarh was not transferred. The territorial commissions reported and their recommendations were not implemented. The water tribunal's work has been overtaken by litigation. The inquiries into 1984 have run for forty years.
The accord is the most complete statement of what Punjab's political demands actually were, and almost none of it was carried out. Every subsequent negotiation has started from the same list.
It was signed on 24 July 1985 and covered Chandigarh, the river waters, the territorial claims, a commission on the Anandpur Sahib Resolution's demands, and rehabilitation.
The Akali Dal contested and won the election held weeks later on the strength of it, which is the only occasion on which a Punjab government has been formed on an agreement with the centre rather than against one.
Longowal was killed on 20 August 1985, twenty-seven days after signing. The accord's central provisions remain unimplemented forty years later.
