Indo-Pakistani war of 1971 in the context of "India Gate"

The Bangladesh Liberation War (Bengali: মুক্তিযুদ্ধ, pronounced [mukt̪iɟud̪d̪ʱo]), also known as the Bangladesh War of Independence, was an armed conflict sparked by the rise of the Bengali nationalist and self-determination movement in East Pakistan, which resulted in the independence of Bangladesh. The war began when the Pakistani military junta based in West Pakistan—under the orders of Yahya Khan—launched Operation Searchlight against East Pakistanis on the night of 25 March 1971, initiating the Bangladesh genocide.

In response to the violence, members of the Mukti Bahini—a guerrilla resistance movement formed by Bengali military, paramilitary and civilians—launched a mass guerrilla war against the Pakistani military, liberating numerous towns and cities in the war's initial months. At first, the Pakistan Army regained momentum during the monsoon, but Bengali guerrillas counterattacked by carrying out widespread sabotage, including through Operation Jackpot against the Pakistan Navy, while the nascent Bangladesh Air Force flew sorties against Pakistani military bases. India joined the war on 3 December 1971 in support of the Mukti Bahini, after Pakistan launched preemptive air strikes on northern India. The subsequent Indo-Pakistani War involved fighting on two fronts; with air supremacy achieved in the eastern theater and the rapid advance of the Allied Forces of Mukti Bahini and the Indian military, Pakistan surrendered in Dhaka on 16 December 1971, in what remains to date the largest surrender of armed personnel since the Second World War.

Surrender, in military terms, is the relinquishment of control over territory, combatants, fortifications, ships or armament to another power. A surrender may be accomplished peacefully or it may be the result of defeat in battle. A sovereign state may surrender following defeat in a war, usually by signing a peace treaty or capitulation agreement. A battlefield surrender, either by individuals or when ordered by officers, normally results in those surrendering becoming prisoners of war.

Indian nationalism is an instance of civic nationalism. It is inclusive of all of the people of India, despite their diverse ethnic, linguistic and religious backgrounds. Indian nationalism can trace roots to pre-colonial India, but was fully developed during the Indian independence movement which campaigned against nearly two centuries of British rule. Indian nationalism quickly rose to popularity in India through these united anti-colonial coalitions and movements. Independence movement figures like Mahatma Gandhi, Subhas Chandra Bose, and Jawaharlal Nehru spearheaded the Indian nationalist movement, with the Indian National Congress playing a major role.

India's independence in 1947 was coupled with separation from Muslim-majority Pakistan, with that nation being carved out of British India's northwestern and eastern regions. Afterwards, Prime Minister Nehru and his successors continued to campaign on Indian nationalism in the face of border wars with both China and Pakistan, with the latter clashing several times over the Kashmir border region. After the Indo-Pakistani war of 1971 and the Bangladesh Liberation War, which resulted in East Pakistan's independence, Indian nationalism reached its post-independence peak. However by the 1980s, religious tensions reached a boiling point, the Indian National Congress lost its political dominance and became more authoritarian, and Indian nationalism sluggishly collapsed in the following decades. Despite its decline and the rise of religious nationalism, Indian nationalism and its historic figures continue to strongly influence the politics of India and reflect an opposition to the sectarian strands of Hindu nationalism and Muslim nationalism.

Zulfikar Ali Bhutto NPk (5 January 1928 – 4 April 1979) was a Pakistani barrister, politician and statesman who served as the fourth president of Pakistan from 1971 to 1973 and later as the ninth prime minister of Pakistan from 1973 until his overthrow in 1977. He was also the founder and first chairman of the Pakistan People's Party (PPP) from 1967 until his execution in 1979.

Born in Sindh and educated at the University of California, Berkeley and the University of Oxford, Bhutto trained as a barrister at Lincoln's Inn before entering politics. He was a cabinet member during president Iskandar Mirza's tenure, holding various ministries during president Ayub Khan's military rule from 1958. Bhutto became the foreign minister in 1963, advocating for Operation Gibraltar in Kashmir, leading to the 1965 war with India. Following the Tashkent Declaration, he was dismissed from the government. Bhutto established the PPP in 1967, focusing on a left-wing and socialist agenda, and contested the 1970 general election, arising as the largest political party in Western Pakistan with a landslide victory in Punjab and Sindh; and a coalition victory with National Awami Party in Balochistan and the North-West Frontier. The Awami League, victorious with a landslide in East Pakistan, and the PPP were unable to agree on power transfer, leading to civil unrest in the east — further intensified by military action under Yahya Khan's military government — followed by a civil war and a war with India, resulting in the creation of Bangladesh. After Pakistan's loss in the east, Yahya resigned amidst a military revolt against him and Bhutto assumed the presidency in December 1971, imposing emergency rule and securing a ceasefire on the western front.

The Razakars (Urdu: رضا کار Bengali: রাজাকার, lit. 'Volunteer') were a gendarmerie and paramilitary force in East Pakistan organised by General Tikka Khan in 1971. They were organised as a counter-insurgency force to fight Mukti Bahini members in the Bangladesh War of Independence, and played an infamous role in the 1971 Bangladesh genocide. The Razakars were disbanded following Pakistan's defeat and surrender in the 1971 Indo-Pakistani War.
