Indo-Pakistani War of 1971 in the context of "India–Pakistan barrier"

The history of independent India or history of Republic of India began when the country became an independent sovereign state within the British Commonwealth on 15 August 1947. Direct administration by the British, which began in 1858, affected a political and economic unification of the subcontinent. When British rule came to an end in 1947, the subcontinent was partitioned along religious lines into two separate countries—India, with a majority of Hindus, and Pakistan, with a majority of Muslims. Concurrently the Muslim-majority northwest and east of British India was separated into the Dominion of Pakistan, by the Partition of India. The partition led to a population transfer of more than 10 million people between India and Pakistan and the death of about one million people. Indian National Congress leader Jawaharlal Nehru became the first Prime Minister of India, but the leader most associated with the independence struggle, Mahatma Gandhi, accepted no office. The constitution adopted in 1950 made India a democratic republic with Westminster style parliamentary system of government, both at federal and state level respectively. The democracy has been sustained since then. India's sustained democratic freedoms are unique among the world's newly independent states, despite its history being perforated by several crises and recent worries of democratic backsliding under the premiership of Narendra Modi.

The country has faced religious violence, corruption, poverty, unemployment, language conflicts, naxalism, terrorism, separatist insurgencies in North East India and gender-based violence. India has unresolved territorial disputes over Kashmir and Arunachal Pradesh with China which escalated into a war in 1962 and 1967, Kashmir with Pakistan which resulted in wars in 1947–1948, 1965, 1971 and 1999 and Kalapani with Nepal. India was neutral in the Cold War, and was a leader in the Non-Aligned Movement. However, it made a loose alliance with the Soviet Union from 1971, when Pakistan was allied with the United States and the People's Republic of China.

The Indian Armed Forces are the military forces of the Republic of India. It consists of three professional uniformed services: the Indian Army, the Indian Navy, and the Indian Air Force. Additionally, the Indian Armed Forces are supported by the Central Armed Police Forces, the Indian Coast Guard, and the Special Frontier Force and various inter-service commands and institutions such as the Strategic Forces Command, the Andaman and Nicobar Command, and the Integrated Defence Staff. The President of India is the Supreme Commander of the Indian Armed Forces but the executive authority and responsibility for national security is vested in the Prime Minister of India and their chosen Cabinet Ministers. The Indian Armed Forces are under the management of the Ministry of Defence of the Government of India. With strength of over 1.4 million active personnel, it is the world's second-largest military force and has the world's largest volunteer army. It also has the fifth-largest defence budget in the world.

The Indian Armed Forces have been engaged in a number of major military operations, including: the Indo-Pakistani wars of 1947, 1965, and 1971, the Portuguese-Indian War, the Sino-Indian War, the Indo-China War of 1967, the Kargil War, the Siachen conflict, and the 2025 India-Pakistan conflict among others. India honours its armed forces and military personnel annually on Armed Forces Flag Day, 7 December. Armed with the nuclear triad, the Indian Armed Forces are steadily undergoing modernisation, with investments in areas such as futuristic soldier systems and ballistic missile defence systems.

Baltistan (English: /ˌbɔːltɪˈstɑːn/, Urdu: [bəlt̪ɪst̪aːn]); also known as Baltiyul or Little Tibet, is a mountainous region in the Pakistani-administered territory of Gilgit-Baltistan and constitutes a northern portion of the larger Kashmir region that has been the subject of a dispute between India and Pakistan since 1947. It is located near the Karakoram (south of K2) and borders Gilgit to the west, China's Xinjiang to the north, Indian-administered Ladakh to the southeast, and the Indian-administered Kashmir Valley to the southwest. The average altitude of the region is over 3,350 metres (10,990 ft). Baltistan is largely administered under the Baltistan Division.

Prior to the partition of British India in 1947, Baltistan was part of the princely state of Jammu and Kashmir, having been conquered by Gulab Singh's armies in 1840. Baltistan and Ladakh were administered jointly under one wazarat (district) of the state. The region retained its identity in this setup as the Skardu tehsil, with Kargil and Leh being the other two tehsils of the district. After Hari Singh, the last maharaja of Jammu and Kashmir, acceded to the Dominion of India in 1947, his local governor in Gilgit was overthrown by the Gilgit Scouts, who then took the entire region for Pakistan during the Indo-Pakistani War of 1947–1948. The Gilgit Agency and Skardu tehsil, as well as a portion of Kargil tehsil, have since been under Pakistani governance while the Kashmir Valley as well as Leh tehsil and most of the Kargil tehsil remain under Indian governance. The Chorbat Valley, geographically in the Baltistan region, was de-facto partitioned when its four villages (with one Bogdang already under Indian control since 1947) were captured by India during the Indo-Pakistani War of 1971, and were incorporated into the erstwhile state of Jammu and Kashmir (now in Ladakh).

The Kashmir conflict is a territorial conflict over the Kashmir region, primarily between India and Pakistan, and also between China and India in the northeastern portion of the region. The conflict started after the partition of India in 1947 as both India and Pakistan claimed the entirety of the former princely state of Jammu and Kashmir. It is a dispute over the region that escalated into three wars between India and Pakistan and several other armed skirmishes. India controls approximately 55% of the land area of the region that includes Jammu, the Kashmir Valley, most of Ladakh, the Siachen Glacier, and 70% of its population; Pakistan controls approximately 30% of the land area that includes Azad Kashmir and Gilgit-Baltistan; and China controls the remaining 15% of the land area that includes the Aksai Chin region, the mostly uninhabited Trans-Karakoram Tract, and part of the Demchok sector.

After the partition of India and a rebellion in the western districts of the state, Pakistani tribal militias invaded Kashmir, leading the Hindu ruler of Jammu and Kashmir to join India. The resulting Indo-Pakistani War ended with a UN-mediated ceasefire along a line that was eventually named the Line of Control. In 1962, China invaded and fought a war with India along the disputed Indo-Chinese border, including in Indian administered-Ladakh, marking their entry to the Kashmir conflict. In 1965, Pakistan attempted to infiltrate Indian-administered Kashmir to precipitate an insurgency there, resulting in another war fought by the two countries over the region. After further fighting during the war of 1971, the Simla Agreement formally established the Line of Control between the territories under Indian and Pakistani control. In 1999, an armed conflict between the two countries broke out again in Kargil with no effect on the status quo.

Since the partition of British India in 1947 and subsequent creation of the dominions of India and Pakistan, the two countries have been involved in a number of wars, conflicts, and military standoffs. A long-running dispute over Kashmir and cross-border terrorism have been the predominant cause of conflict between the two states, with the exception of the Indo-Pakistani War of 1971, which occurred as a direct result of hostilities stemming from the Bangladesh Liberation War in erstwhile East Pakistan (now Bangladesh).

The Simla Agreement, also spelled Shimla Agreement, is a bilateral peace treaty and framework agreement signed between India and Pakistan on 2 July 1972 in Shimla, the capital of the Indian state of Himachal Pradesh. It followed the Indo-Pakistani War of 1971, which began after India intervened in a civil war in East Pakistan on Mukti Bahini's side against Pakistani state forces.

The treaty's official purpose is stated to serve as a way for both countries to "put an end to the conflict and confrontation that have hitherto marred their relations" and to conceive the steps to be taken for further normalization of India–Pakistan relations while also laying down the principles that should govern their future interactions.
