The Simla Agreement was signed on 3 July 1972 in Shimla, the capital of the Indian state of Himachal Pradesh, between India and Pakistan.  This led to the war of liberation of Bangladesh in 1971, which led to the independence of Bangladesh, formerly known as East Pakistan and part of the territory of Pakistan. India entered the war as an ally of Bangladesh, which turned the war into an Indo-Pakistan war in 1971.  This agreement, commonly known as the Simla Pact, was born in 1971 from the war between the two countries over developments in the eastern wing of Pakistan. The aim of the agreement was to define the principles that should govern their future relations. It also provided for measures to be taken to further normalize bilateral relations. Most importantly, it forced the two countries to “resolve their differences through bilateral negotiations by peaceful means.” The Simla Agreement is “much more than a peace treaty that attempts to reverse the consequences of the 1971 war (i.e. the withdrawal of troops and the exchange of PoWs).” It was a blue impression for good-neighbourly relations between India and Pakistan. This agreement is ratified by both countries in accordance with their respective constitutional procedures and enters into force from the date of exchange of ratification instruments.  For pre-waxes: Origin, effect and results of Simla, has it been a success? The agreement is the result of the two countries` determination to “end the conflict and confrontation that have so far weighed on their relations.” He designed the steps to be taken to further normalize mutual relations and also defined the principles that should govern their future relations.   The Simla Agreement, signed on 2 July 1972 by Prime Minister Indira Gandhi and Pakistani President Zulfikar Ali Bhutto, was much more than a peace treaty that attempted to reverse the consequences of the 1971 war (i.e. military deductions and a PoWs exchange).
It was a blue impression for good-neighbourly relations between India and Pakistan. As part of the Simla Agreement, the two countries pledged to end the conflicts and confrontations that have affected relations in the past and to work towards lasting peace, friendship and cooperation. The Simla Agreement contains a number of guiding principles on which India and Pakistan have agreed and which both sides would adhere to in the management of relations between them. They insist on respect for the territorial integrity and sovereignty of the other; non-interference in the internal affairs of the other; respect for unity, political independence; sovereign equality; and hostile propaganda. However, the following principles of the agreement are particularly noteworthy: the Delhi Agreement on the Repatriation of War and Civilian Internees is a tripartite agreement between these states, signed on 28 August 1973. The agreement was signed by Kamal Hossain, the Foreign Minister of the Government of Bangladesh, Sardar Swaran Singh, the Indian Minister of Foreign Affairs and Aziz Ahmed, Minister of State for Defence and Foreign Affairs of the Pakistani government.  , recalling its agreement of 23 September 1998 that an environment of peace and security is in the supreme national interest of both parties and that the resolution of all outstanding issues, including Jammu and Kashmir, is essential for this purpose. iii) Withdrawals will begin on the effective date of this agreement and will be concluded within 30 days.
 The agreement did not prevent relations between the two countries from deteriorating to the armed conflict, the last time during the 1999 Kargile War. In Operation Meghdoot of 1984, India seized the entire inhospitable region of the Siachens Glacier, where the border was clearly not defined in the agreement (perhaps because the area was considered too arid to be controversial); This was considered by Pakistan to be a violation of the Simla agreement.
