Zulfikar Ali Bhutto (Sindhi: ; Urdu: ; 5 January 1928 4 April 1979) was a Pakistani barrister and politician who served as the ninth Prime Minister of Pakistan from 1973 to 1977, and prior to that was the fourth President of Pakistan from 1971 to 1973. His government drafted the Constitution of Pakistan in 1973, which is the current constitution of the country. He was also the founder of the Pakistan People's Party (PPP) and served as its chairman until his execution in 1979.Born in modern-day 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 as one of President Iskander Mirza's cabinet members, and was assigned several ministries during President Ayub Khan's military rule from 1958. Appointed Foreign Minister in 1963, Bhutto was a proponent of Operation Gibraltar in Kashmir, leading to war with India in 1965. After the Tashkent Agreement ended hostilities, Bhutto fell out with Ayub Khan and was sacked from government. Bhutto founded the PPP in 1967 on a socialist platform, and contested general elections held by President Yahya Khan in 1970. While the Awami League won a majority of seats overall (nationwide), the PPP won a majority of seats in West Pakistan only (where Awami League did not win any seat); the two parties were unable to agree on the power transfer and a new constitution. In particular, Awami League's Six Point Movement was seen by many in West Pakistan including President Yahya Khan and Z. A. Bhutto as a way to break up the country. Stubbornness of Bhutto and Yahya to accept a Bengali as the Prime Minister of Pakistan led to the uprisings and movements in East Pakistan, and counter steps taken by the Army ordered by Yahya Khan and supported by Bhutto ultimately led to the Creation of Bangladesh. In the wake of Pakistan losing the war against Bangladesh-allied India in December, 1971, Bhutto took the presidency in December 1971 and emergency rule was imposed. When Bhutto set about rebuilding Pakistan, he stated his intention was to "rebuild confidence and rebuild hope for the future".By July 1972, Bhutto recovered 93,000 prisoners of war and 5,000 sq mi of Indian-held territory after signing the Simla Agreement. He strengthened ties with China and Saudi Arabia, recognised Bangladesh, and hosted the second Organisation of the Islamic Conference in Lahore in 1974. Domestically, Bhutto's reign saw parliament unanimously approve a new constitution in 1973, upon which he appointed Fazal Ilahi Chaudhry President and switched to the newly empowered office of Prime Minister. He also played an integral role in initiating the country's nuclear programme. However, Bhutto's nationalisation of much of Pakistan's fledgling industries, healthcare, and educational institutions was met with economic stagnation. After dissolving provincial feudal governments in Balochistan was met with unrest, Bhutto also ordered an army operation in the province in 1973, causing thousands of civilian casualties. Despite civil disorder, the PPP won parliamentary elections in 1977 by a wide margin. However, the opposition alleged widespread vote rigging, and violence escalated across the country. On 5 July that same year, Bhutto was deposed in a military coup by his appointed army chief Zia-ul-Haq, before being controversially tried and executed by the Supreme Court of Pakistan in 1979 for authorising the murder of a political opponent.Bhutto remains a contentious figure, being hailed for his nationalism and secular internationalist agenda, yet criticized for intimidating his political opponents and for human rights violations. He is often considered one of Pakistan's greatest leaders, and his party, the PPP, remains among Pakistan's largest, with his daughter Benazir Bhutto being twice elected Prime Minister, while his son-in-law and Benazir's husband, Asif Ali Zardari, served as president.

A coup d'état ( (listen); French for "blow of state"), often shortened to coup in English (also known as an overthrow), is a seizure and removal of a government and its powers. Typically, it is an illegal seizure of power by a political faction, rebel group, military, or a dictator. Many scholars consider a coup successful when the usurpers seize and hold power for at least seven days.
