Question: The Arab nationalist who helped inspire the Aden Emergency was born in what year?

full_context: Document 1: History of Egypt under Gamal Abdel Nasser: The history of Egypt under Gamal Abdel Nasser covers the period of Egyptian history from the Egyptian Revolution of 1952, of which Gamal Abdel Nasser was one of the two principal leaders, spanning Nasser's presidency of Egypt from 1956, to his death in 1970. Nasser's tenure as Egypt's leader heralded a new period of modernization, and socialist reform in Egypt, and a staunch advocacy of pan-Arab nationalism (including a short-lived union with Syria), and Developing World solidarity. His prestige in Egypt and throughout the Arab World soared in the wake of his nationalisation of the Suez Canal in 1956, and Egypt's political victory in the subsequent Tripartite Aggression, but was damaged badly by Israel's successful invasion and occupation of Egyptian and Arab territory in the Six-Day War of 1967.
Document 2: Nasser al-Bahri: Nasser al-Bahri (1972 – December 26, 2015), also known by his "kunya" or "nom de guerre" as Abu Jandal – "father of death", was a member of al-Qaeda in Afghanistan from 1996 to 2000. He gave his bayat (secret oath of allegiance) to Osama bin Laden in 1998, an experience he describes in detail in his memoir. He was in al-Qaeda for four years, first as one of bin Laden's twelve bodyguards, and then as head of Osama bin Laden's security detail. A citizen of Yemen born in Saudi Arabia, Al-Bahri was radicalized in his teens by dissident Saudi Ulemas and participated in clandestine political activities which were funded in part by people trafficking. Having determined to become a jihadist he went first to Bosnia and then, briefly, to Somalia before arriving in Afghanistan in 1996 in the hope of joining Al-Qaeda, which he soon did. After four years, al-Bahri became "disillusioned", largely because bin Laden consolidated al-Qaeda's relationship with the Taliban by giving his bayat to its leader, Mullah Omar, but also because he had married and become a father.
Document 3: Radfan Campaign: The Radfan Campaign was a series of British military actions during the Aden Emergency. It took place in the mountainous Radfan region near the border with Yemen. Local tribesmen connected with the NLF began raiding the road connecting with Aden with the town of Dhala.
Document 4: National Liberation Front (South Yemen): The National Liberation Front (Arab: الجبهة القوميّة) or NLF was a Marxist paramilitary organization and a political party operating in the Federation of South Arabia, (now southern Yemen) during the Aden Emergency. During the North Yemen Civil War, fighting spilled over into South Yemen as the British attempted to establish an autonomous colony known as the Federation of South Arabia. Following the exit of the British armed forces, the NLF seized power from its rival, the Arab nationalist Front for the Liberation of Occupied South Yemen (FLOSY). In the aftermath of the Emergency, the NLF reorganized itself into the Yemeni Socialist Party and established a single-party Marxist-Leninist regime, known as the People's Democratic Republic of Yemen.
Document 5: Mustafa Ahmed Hassan Hamza: Mustafa Hamza (born 1956) is an Egyptian commander of the military branch of the Islamic Group. He was sentenced to death in absentia by an Egyptian court in the Returnees from Afghanistan case. It is believed he took part in the 1981 assassination of Egyptian President Anwar El Sadat, the attempted assassination of President Hosni Mubarak in Addis Ababa in June 1995, and the Luxor massacre, which killed more than 60 tourists and Egyptians in 1997. He was in Iran until May 2004, when he was extradited to Egypt. He was pardoned in 2012. Also goes by the aliases Abu Hazem, Mohamed Gamal El-Sayed, Mohamed Gamal El-Sayed Ali Khalil.
Document 6: Aden Street riots: The Aden Street riots took place in early 1967 during the Aden Emergency. On 19-20 January 1967 the NLF prompted street rioting in Aden. The Aden police lost control, so British High Commissioner Sir Richard Turnbull deployed British troops to crush the riots. This was followed by pro-FLOSY rioters taking to the streets which then led to conflict with British troops until February. The mood created by the riots helped lead to the Arab Police mutiny.
Document 7: Abdel Latif Boghdadi (politician): Abdel Latif Boghdadi or Abd el-Latif el-Baghdadi (20 September 1917 – 9 September 1999) (Arabic: عبد اللطيف البغدادي‎ ‎ ) was an Egyptian politician, senior air force officer, and judge. An original member of the Free Officers Movement which overthrew the monarchy in Egypt in the 1952 Revolution, Boghdadi later served as Gamal Abdel Nasser's vice president. The French author Jean Lacouture called Boghdadi "a robust manager" who only lacked "stature comparable to Nasser's." The two leaders had a fallout over Nasser's increasingly socialist and pro-USSR policies and Boghdadi subsequently withdrew from political life in 1964, although he mended ties with Nasser before the latter's death in 1970.
Document 8: Aden Emergency: The Aden Emergency, also known as the Radfan Uprising, was an insurgency against the British Crown forces in the British controlled territories of South Arabia which now form part of Yemen. Partly inspired by Nasser's pan Arab nationalism, it began on 14 October 1963 with the throwing of a grenade at a gathering of British officials at Aden Airport. A state of emergency was then declared in the British Crown colony of Aden and its hinterland, the Aden Protectorate. The emergency escalated in 1967 and hastened the end of British rule in the territory which had begun in 1839. On 30 November 1967, British forces withdrew and the independent People's Republic of South Yemen was proclaimed.
Document 9: Arab Revolt: The Arab Revolt (Arabic: الثورة العربية‎ ‎ , "al-Thawra al-‘Arabiyya "; Turkish: "Arap İsyanı" ) or Great Arab Revolt (Arabic: الثورة العربية الكبرى‎ ‎ , "al-Thawra al-‘Arabiyya al-Kubrā ") was officially initiated by Sherif Hussein bin Ali at Mecca on 10 June 1916 (9 Sha'ban of the Islamic calendar for that year) although his sons ‘Ali and Faisal had already initiated operations at Medina starting on 5 June with the aim of securing independence from the ruling Ottoman Turks and creating a single unified Arab state spanning from Aleppo in Syria to Aden in Yemen.
Document 10: Yemeni Civil War (2015–present): The Yemeni Civil War is an ongoing conflict that began in 2015 between two factions claiming to constitute the Yemeni government, along with their supporters and allies. Houthi forces controlling the capital Sana'a and allied with forces loyal to the former president Ali Abdullah Saleh have clashed with forces loyal to the government of Abdrabbuh Mansur Hadi, based in Aden. Al-Qaeda in the Arabian Peninsula (AQAP) and the Islamic State of Iraq and the Levant have also carried out attacks, with AQAP controlling swathes of territory in the hinterlands, and along stretches of the coast.

He was one of the nine men who had constituted themselves as the committee of the Free Officers Movement, led the country's cavalry corps during the uprising and was one of only three living members of the Revolutionary Command Council at the time of his death.

Document 14: Arab Police mutiny: The Arab Police mutiny was an incident during the Aden Emergency where Arab soldiers and police mutinied against British troops. While the mutiny itself was localized and quickly suppressed, it undermined the South Arabian Federation which had been organized by Britain in 1959 as an intended successor to direct colonial rule.
Document 15: Egyptian revolution of 1952: The Egyptian revolution of 1952 (Arabic: ثورة 23 يوليو 1952‎ ‎ ), also known as the July 23 revolution, began on July 23, 1952, by the Free Officers Movement, a group of army officers led by Muhammad Naguib and Gamal Abdel Nasser. The revolution was initially aimed at overthrowing King Faruq. However, the movement had more political ambitions, and soon moved to abolish the constitutional monarchy and aristocracy of Egypt and Sudan, establish a republic, end the British occupation of the country, and secure the independence of Sudan (previously governed as an Anglo-Egyptian condominium). The revolutionary government adopted a staunchly nationalist, anti-imperialist agenda, which came to be expressed chiefly through Arab nationalism, and international non-alignment.
