On December 20, 1971 President Agha Muhammad Yahya Khan of Pakistan resigned in the wake of the country's catastrophic defeat in the December 1971 war and the loss of East Pakistan, which became Bangladesh, transferring power to Zulfikar Ali Bhutto and ending thirteen years of military rule. Yahya, who had taken power in 1969, had barred the transfer of power to the Awami League after its 1970 election victory, launched the brutal Operation Searchlight in East Pakistan, and led the country into a two-front war with India that ended in the surrender of Pakistani forces at Dhaka on December 16. Public fury, anti-government demonstrations, and pressure from within the army, including a revolt of majors and colonels led by Brigadier F.
B. Ali who demanded his resignation for the loss of the war, forced Yahya out. On December 20 Bhutto, leader of the Pakistan People's Party, was flown back from New York and sworn in as president and chief martial law administrator, returning the government to civilian hands.
Bhutto retired Yahya and other senior officers and placed Yahya under house arrest.

The 1971 Pakistan Military Officer's Revolt, also known as the Majors and Colonels Revolt, refers to the deposition of Yahya Khan's regime by Brigadier F.B. Ali and other officers, whose action overthrew the government and transferred power to the elected civilian representatives, with the revolt succeeding as Yahya Khan and his government resigned and Bhutto took power as president.

West Pakistani troops at Dhaka surrendered to Indian forces on December 16 and East Pakistan became the independent country of Bangladesh, and Yahya Khan resigned four days later, replaced by his foreign minister Zulfikar Ali Bhutto, who put him under house arrest, after which Yahya was paralyzed by a stroke and played no further important political role.
After Pakistan was defeated in 1971 most of the blame was heaped on Yahya Khan, and in the face of serious public agitation he had to step down in favour of Zulfikar Ali Bhutto on 20 December 1971, after which the new President Bhutto ordered the house arrest of his predecessor.

Editorial Note
Coding note: the dataset labels this a popular revolt because mass agitation over the war defeat, combined with an army officers' revolt, forced Yahya out; the deposed leader was not physically harmed at the transfer, matching the dataset fate, though Bhutto placed him under house arrest days later (recorded as immediate aftermath). Arc link: this is distinct from Yahya's own 1969-03-25 rise (enriched in batch 21), when he took power from Ayub Khan; the December 1971 fall closed the Yahya era. Historical weight: the event is inseparable from the independence of Bangladesh (declared December 16 to 21, 1971) and the mass atrocities of Operation Searchlight, which are recorded as context. Bhutto became the first civilian leader since 1958.
