Gamal Abdel Nasser Hussein (15 January 1918 – 28 September 1970) was an Egyptian military officer and revolutionary who served as the second president of Egypt from 1954 until his death in 1970. Nasser led the Egyptian revolution of 1952 and introduced far-reaching land reforms the following year. Following a 1954 assassination attempt by a Muslim Brotherhood member, he cracked down on the organization, put President Mohamed Naguib under house arrest and assumed executive office. He was formally elected president in June 1956.

Nasser's popularity in Egypt and the Arab world skyrocketed after his nationalization of the Suez Canal and his political victory in the subsequent Suez Crisis, known in Egypt as the Tripartite Aggression. Calls for pan-Arab unity under his leadership increased, culminating with the formation of the United Arab Republic with Syria from 1958 to 1961. In 1962, Nasser began a series of major socialist measures and modernization reforms in Egypt. Despite setbacks to his pan-Arabist cause, by 1963 Nasser's supporters gained power in several Arab countries, but he became embroiled in the North Yemen Civil War, and eventually the much larger Arab Cold War. He began his third presidential term in March 1965 after his political opponents were banned from running. Following Egypt's defeat by Israel in the Six-Day War of 1967, Nasser resigned, but he returned to office after popular demonstrations called for his reinstatement. By 1968, Nasser had appointed himself prime minister, launched the War of Attrition to regain the Israeli-occupied Sinai Peninsula, begun a process of depoliticizing the military, and issued a set of political liberalization reforms. After the conclusion of the 1970 Arab League summit, Nasser suffered a heart attack and died. His funeral in Cairo drew five to six million mourners, and prompted an outpouring of grief across the Arab world.

Nasser remains an iconic figure in the Arab world, particularly for his strides towards social justice and Arab unity, his modernization policies, and his anti-imperialist efforts. His presidency also encouraged and coincided with an Egyptian cultural boom, and the launching of large industrial projects, including the Aswan Dam, and Helwan city. Nasser's detractors criticize his authoritarianism, his human rights violations, his anti-Zionism, and the dominance of the military over civil institutions that characterised his tenure, establishing a pattern of military and dictatorial rule in Egypt which has persisted, nearly uninterrupted, to the present day.

Early life

Gamal Abdel Nasser Hussein was born in Bakos, Alexandria, Egypt on 15 January 1918, a year before the tumultuous events of the Egyptian Revolution of 1919. Nasser's father, Abdel Nasser Hussein, was a postal worker born in Beni Mur in Upper Egypt, and raised in Alexandria. Her family came from Mallawi, el-Minya. His parents had married in 1917.

Nasser's family traveled frequently due to his father's work. In 1921, they moved to Asyut and, in 1923, to Khatatba, where Nasser's father ran a post office. Nasser attended a primary school for the children of railway employees until 1924, when he was sent to live with his paternal uncle in Cairo, and to attend the Nahhasin elementary school.

Nasser exchanged letters with his mother and visited her on holidays. He stopped receiving messages at the end of April 1926. Upon returning to Khatatba, he learned that his mother had died after giving birth to his third brother, Shawki, and that his family had kept the news from him. Nasser later stated that "losing her this way was a shock so deep that time failed to remedy". He adored his mother and the injury of her death deepened when his father remarried before the year's end.

In 1928, Nasser went to Alexandria to live with his maternal grandfather and attend the city's Attarin elementary school. After witnessing clashes between protesters and police in Manshia Square, The protest, organized by the ultranationalist Young Egypt Society, called for the end of colonialism in Egypt in the wake of the 1923 Egyptian constitution's annulment by Prime Minister Isma'il Sidqi. before his father bailed him out. His association with the group and active role in student demonstrations during this period "imbued him with a fierce Egyptian nationalism", according to the historian James Jankowski.

When his father was transferred to Cairo in 1933, Nasser joined him and attended al-Nahda al-Masria school. He took up acting in school plays for a brief period and wrote articles for the school's paper, including a piece on French philosopher Voltaire titled "Voltaire, the Man of Freedom". On 12 December, the new king, Farouk, issued a decree restoring the constitution. Despite it having the almost unanimous backing of Egypt's political forces, Nasser strongly objected to the 1936 Anglo-Egyptian Treaty because it stipulated the continued presence of British military bases in the country. the biographies of nationalist leaders Napoleon, Atatürk, Otto von Bismarck and Garibaldi, and the autobiography of Winston Churchill.

Nasser was greatly influenced by Egyptian nationalism, as espoused by politician Mustafa Kamel, poet Ahmed Shawqi, He was especially influenced by Egyptian writer Tawfiq al-Hakim's novel Return of the Spirit, in which al-Hakim wrote that the Egyptian people were only in need of a "man in whom all their feelings and desires will be represented, and who will be for them a symbol of their objective". Disappointed, he enrolled in the law school at King Fuad University, From his readings, Nasser, who frequently spoke of "dignity, glory, and freedom" in his youth, became enchanted with the stories of national liberators and heroic conquerors; a military career became his chief priority.

Convinced that he needed a wasta, or an influential intermediary to promote his application above the others, Nasser managed to secure a meeting with Under-Secretary of War Ibrahim Khairy Pasha, Nasser focused on his military career from then on, and had little contact with his family. At the academy, he met Abdel Hakim Amer and Anwar Sadat, both of whom became important aides during his presidency. After graduating from the academy in July 1938, It was here that Nasser and his closest comrades, including Sadat and Amer, first discussed their dissatisfaction at widespread corruption in the country and their desire to topple the monarchy. Sadat would later write that because of his "energy, clear-thinking, and balanced judgement", Nasser emerged as the group's natural leader.

In 1941, Nasser was posted to Khartoum, Sudan, which was part of Egypt at the time. Nasser returned to Egypt in September 1942 after a brief stay in Sudan, then secured a position as an instructor in the Cairo Royal Military Academy in May 1943. and wished for "calamity" to overtake the British. Nasser stayed in touch with the group's members primarily through Amer, who continued to seek out interested officers within the Egyptian Armed Force's various branches and presented Nasser with a complete file on each of them.

1948 Arab–Israeli War

Nasser's first battlefield experience was in Palestine during the 1948 Arab–Israeli War. He initially volunteered to serve with the Arab Higher Committee (AHC) led by Mohammad Amin al-Husayni. Nasser met with and impressed al-Husayni, but was ultimately refused entry to the AHC's forces by the Egyptian government for reasons that were unclear.

In May 1948, following the British withdrawal, King Farouk sent the Egyptian army into Israel, During the war, he wrote of the Egyptian army's unpreparedness, saying "our soldiers were dashed against fortifications". nicknamed the "Sudanese tiger" by the Israelis). On 12 July, he was lightly wounded in the fighting. By August, his brigade was surrounded by the Israeli Army. Appeals for help from Transjordan's Arab Legion went unheeded, but the brigade refused to surrender. Negotiations between Israel and Egypt finally resulted in the ceding of Faluja to Israel. According to veteran journalist Eric Margolis, the defenders of Faluja, "including young army officer Gamal Abdel Nasser, became national heroes" for enduring Israeli bombardment while isolated from their command.

Still stationed after the war in the Faluja enclave, Nasser agreed to an Israeli request to identify 67 killed soldiers of the "religious platoon". The expedition was led by Rabbi Shlomo Goren and Nasser personally accompanied him, ordering the Egyptian soldiers to stand at attention. They spoke briefly, and according to Goren, after learning what the square phylacteries found with the soldiers were, Nasser told him that he "now understands their courageous stand". During an interview on Israeli TV in 1971, Rabbi Goren claimed the two agreed to meet again when the time of peace comes.

The Egyptian singer Umm Kulthum hosted a public celebration for the officers' return despite reservations from the royal government, which had been under British pressure to prevent the reception. The apparent difference in attitude between the government and the general public increased Nasser's determination to topple the monarchy. Nasser had also felt bitter that his brigade had not been relieved despite the resilience it displayed. He started writing his book Philosophy of the Revolution during the siege. Its success and evident popular support among the Syrian people encouraged Nasser's revolutionary pursuits. Nasser organized the Free Officers' founding committee, which eventually comprised fourteen men from different social and political backgrounds, including representation from Young Egypt, the Muslim Brotherhood, the Egyptian Communist Party, and the aristocracy. Accusations of corruption against Wafd politicians began to surface, however, breeding an atmosphere of rumor and suspicion that consequently brought the Free Officers to the forefront of Egyptian politics. By then, the organization had expanded to around ninety members. According to Khaled Mohieddin, "nobody knew all of them and where they belonged in the hierarchy except Nasser".

On 11 October 1951, the Wafd government abrogated the unpopular Anglo-Egyptian Treaty of 1936 by which the United Kingdom had the right to maintain its military forces in the Suez Canal Zone. In January 1952, he and Hassan Ibrahim attempted to kill the royalist general Hussein Sirri Amer by firing their submachine guns at his car as he drove through the streets of Cairo. Naguib won overwhelmingly and the Free Officers, through their connection with a leading Egyptian daily, al-Misri, publicized his victory while praising the nationalistic spirit of the army.

The Free Officers' intention was not to install themselves in government, but to re-establish a parliamentary democracy. Nasser did not believe that a low-ranking officer like himself (a lieutenant colonel) would be accepted by the Egyptian people, and so selected General Naguib to be his "boss" and lead the coup in name. The revolution they had long sought was launched on 22 July and was declared a success the next day. The Free Officers seized control of all government buildings, radio stations, and police stations, as well as army headquarters in Cairo. While many of the rebel officers were leading their units, Nasser donned civilian clothing to avoid detection by royalists and moved around Cairo monitoring the situation. Under pressure from the Americans, Nasser had agreed to exile the deposed king with an honorary ceremony.

On 18 June 1953, the monarchy was abolished and the Republic of Egypt declared, with Naguib as its first president. The Free Officers then governed as the Revolutionary Command Council (RCC) with Naguib as chairman and Nasser as vice-chairman. Relations between the RCC and Maher grew tense, however, as the latter viewed many of Nasser's schemes—agrarian reform, abolition of the monarchy, reorganization of political parties—as too radical, culminating in Maher's resignation on 7 September. Naguib assumed the additional role of prime minister, and Nasser that of deputy prime minister. In September, the Agrarian Reform Law was put into effect.

In January 1953, Nasser overcame opposition from Naguib and banned all political parties, creating a one-party system under the Liberation Rally, a loosely structured movement whose chief task was to organize pro-RCC rallies and lectures, with Nasser its secretary-general. Despite the dissolution order, Nasser was the only RCC member who still favored holding parliamentary elections, according to his fellow officer Abdel Latif Boghdadi.

When Naguib began showing signs of independence from Nasser by distancing himself from the RCC's land reform decrees and drawing closer to Egypt's established political forces, namely the Wafd and the Brotherhood, Nasser resolved to depose him. On 26 February, Nasser accepted the resignation, put Naguib under house arrest, As Naguib intended, a mutiny immediately followed, demanding Naguib's reinstatement and the RCC's dissolution. However, on 27 February, Nasser's supporters in the army launched a raid on the GHQ, ending the mutiny. Later that day, hundreds of thousands of protesters, mainly belonging to the Brotherhood, called for Naguib's return and Nasser's imprisonment. In response, a sizable group within the RCC, led by Khaled Mohieddin, demanded Naguib's release and return to the presidency.

On 5 March, Nasser's security coterie arrested thousands of participants in the uprising. with one million transport workers launching a strike and thousands of peasants entering Cairo in protest in late March. Naguib sought to crack down on the protesters, but his requests were rebuffed by the heads of the security forces. Between April and June, hundreds of Naguib's supporters in the military were either arrested or dismissed, and Mohieddin was informally exiled to Switzerland to represent the RCC abroad.

Assuming chairmanship of RCC

On 26 October 1954, Muslim Brotherhood member Mahmoud Abdel-Latif attempted to assassinate Nasser while he was delivering a speech in Alexandria, broadcast to the Arab world by radio, to celebrate the British military withdrawal. The gunman was away from him and fired eight shots, but all missed Nasser. Panic broke out in the mass audience, but Nasser maintained his posture and raised his voice to appeal for calm.</blockquote>

The crowd roared in approval and Arab audiences were electrified. The assassination attempt backfired, quickly playing into Nasser's hands. Upon returning to Cairo, he ordered one of the largest political crackdowns in the modern history of Egypt, Naguib was removed from the presidency and put under house arrest, but was never tried or sentenced, and no one in the army rose to defend him. With his rivals neutralized, Nasser became the undisputed leader of Egypt. To promote himself and the Liberation Rally, he gave speeches in a cross-country tour, Both Umm Kulthum and Abdel Halim Hafez, the leading Arab singers of the era, performed songs praising Nasser's nationalism. Others produced plays denigrating his political opponents. In January 1955, the RCC appointed him as their president, pending national elections. On 28 February 1955, Israeli troops attacked the Egyptian-held Gaza Strip with the stated aim of suppressing Palestinian fedayeen raids. Nasser did not feel that the Egyptian Army was ready for a confrontation and did not retaliate militarily. His failure to respond to Israeli military action demonstrated the ineffectiveness of his armed forces and constituted a blow to his growing popularity. Nasser subsequently ordered the tightening of the blockade on Israeli shipping through the Straits of Tiran and restricted the use of airspace over the Gulf of Aqaba by Israeli aircraft in early September. Nasser turned to the Eastern Bloc and concluded a armaments agreement with Czechoslovakia on 27 September.

Adoption of neutralism

At the Bandung Conference in Indonesia in late April 1955, Nasser was treated as the leading representative of the Arab countries and was one of the most popular figures at the summit. He had paid earlier visits to Pakistan (9 April), India (14 April), Burma, and Afghanistan on the way to Bandung, and previously cemented a treaty of friendship with India in Cairo on 6 April, strengthening Egyptian–Indian relations on the international policy and economic development fronts.

Nasser mediated discussions between the pro-Western, pro-Soviet, and neutralist conference factions over the composition of the "Final Communique"

Following Bandung, Nasser officially adopted the "positive neutralism" of Yugoslavian president Josip Broz Tito and Indian Prime Minister Jawaharlal Nehru as a principal theme of Egyptian foreign policy regarding the Cold War. Nasser was welcomed by large crowds of people lining the streets of Cairo on his return to Egypt on 2 May and was widely heralded in the press for his achievements and leadership in the conference. Consequently, Nasser's prestige was greatly boosted, as was his self-confidence and image.

1956 constitution and presidency

With his domestic position considerably strengthened, Nasser was able to secure primacy over his RCC colleagues and gained relatively unchallenged decision-making authority,

In January 1956, the new Constitution of Egypt was drafted, entailing the establishment of a single-party system under the National Union (NU), The NU was a reconfiguration of the Liberation Rally, which Nasser determined had failed in generating mass public participation. In the new movement, Nasser attempted to incorporate more citizens, approved by local-level party committees, in order to solidify popular backing for his government. The constitution granted women's suffrage, prohibited discrimination by sex, and entailed special protection for women in the workplace. Coinciding with the new constitution and Nasser's presidency, the RCC dissolved itself and its members resigned their military commissions as part of the transition to civilian rule. During the deliberations surrounding the establishment of a new government, Nasser began a process of sidelining his rivals among the original Free Officers, while elevating his closest allies to high-ranking positions in the cabinet.

Nasser was informed of the British–American withdrawal in a news statement while aboard a plane returning to Cairo from Belgrade, and took great offense. Although ideas for nationalizing the Suez Canal Company were in the offing after the UK agreed to withdraw its military from Egypt in 1954 (the last British troops left on 13 June 1956), journalist Mohamed Hassanein Heikal asserts that Nasser made the final decision to nationalize the company that operated the waterway between 19 and 20 July.

On 26 July 1956, Nasser gave a speech in Alexandria announcing the nationalization of the Suez Canal Company as a means to fund the Aswan Dam project in light of the British–American withdrawal. In the speech, he denounced British imperialism in Egypt and British control over the canal company's profits, and upheld that the Egyptian people had a right to sovereignty over the waterway, especially since "120,000 Egyptians had died building it". although he ensured that all existing stockholders would be paid off.

The nationalization announcement was greeted very emotionally by the audience and, throughout the Arab world, thousands entered the streets shouting slogans of support. US ambassador Henry A. Byroade stated, "I cannot overemphasize [the] popularity of the Canal Company nationalization within Egypt, even among Nasser's enemies." According to Aburish, this was Nasser's largest pan-Arab triumph at the time and "soon his pictures were to be found in the tents of Yemen, the souks of Marrakesh, and the posh villas of Syria". Nasser dismissed their claims, and believed that the UK would not be able to intervene militarily for at least two months after the announcement, and dismissed Israeli action as "impossible". In early October, the UN Security Council met on the matter of the canal's nationalization and adopted a resolution recognizing Egypt's right to control the canal as long as it continued to allow passage through it for foreign ships. According to Heikal, after this agreement, "Nasser estimated that the danger of invasion had dropped to 10 percent". Shortly thereafter, however, the UK, France, and Israel made a secret agreement to take over the Suez Canal, occupy the Suez Canal zone, and topple Nasser.

On 29 October 1956, Israeli forces crossed the Sinai Peninsula, overwhelmed Egyptian army posts, and quickly advanced to their objectives. Two days later, British and French planes bombarded Egyptian airfields in the canal zone. Nasser ordered the military's high command to withdraw the Egyptian Army from Sinai to bolster the canal's defenses. Nasser also ordered blockage of the canal by sinking or otherwise disabling forty-nine ships at its entrance. and some 5,000 Egyptian soldiers were captured by the Israeli Army. To counterbalance the Egyptian Army's dismal performance, Nasser authorized the distribution of about 400,000 rifles to civilian volunteers and hundreds of militias were formed throughout Egypt, many led by Nasser's political opponents.

It was at Port Said that Nasser saw a confrontation with the invading forces as being the strategic and psychological focal point of Egypt's defense. A third infantry battalion and hundreds of national guardsmen were sent to the city as reinforcements, while two regular companies were dispatched to organize popular resistance. The Egyptian Army commander in the city was preparing to request terms for a ceasefire, but Nasser ordered him to desist. The British-French forces managed to largely secure the city by 7 November. Nasser commended Eisenhower, stating he played the "greatest and most decisive role" in stopping the "tripartite conspiracy". By the end of December, British and French forces had totally withdrawn from Egyptian territory, As a result of the Suez Crisis, Nasser brought in a set of regulations imposing rigorous requirements for residency and citizenship as well as forced expulsions, mostly affecting British and French nationals and Jews with foreign nationality, as well as many Egyptian Jews. Some 25,000 Jews, almost half of the Jewish community, left in 1956, mainly for Israel, Europe, the United States and South America.

After the fighting ended, Amer accused Nasser of provoking an unnecessary war and then blaming the military for the result. On 8 April, the canal was reopened, and Nasser's political position was enormously enhanced by the widely perceived failure of the invasion and attempt to topple him. British diplomat Anthony Nutting claimed the crisis "established Nasser finally and completely" as the rayyes (president) of Egypt. Historian Adeed Dawisha credited Nasser's status to his "charisma, bolstered by his perceived victory in the Suez Crisis". Lebanese sympathizers of Nasser and the Egyptian embassy in Beirut—the press center of the Arab world—bought out Lebanese media outlets to further disseminate Nasser's ideals. Nasser also enjoyed the support of Arab nationalist civilian and paramilitary organizations throughout the region. His followers were numerous and well-funded, but lacked any permanent structure and organization. They called themselves "Nasserites", despite Nasser's objection to the label (he preferred the term "Arab nationalists"). Although Nasser was an opponent of communism in the region, his promotion of pan-Arabism was viewed as a threat by pro-Western states in the region. Eisenhower tried to isolate Nasser and reduce his regional influence by attempting to transform King Saud into a counterweight. Sulayman al-Nabulsi brought Jordan into a military pact with Egypt, Syria, and Saudi Arabia.

Relations between Nasser and King Hussein of Jordan deteriorated in April when Hussein implicated Nasser in two coup attempts against him—although Nasser's involvement was never established—and dissolved al-Nabulsi's cabinet. Relations with King Saud also became antagonistic as the latter began to fear that Nasser's increasing popularity in Saudi Arabia was a genuine threat to the royal family's survival.

By the end of 1957, Nasser nationalized all remaining British and French assets in Egypt, including the tobacco, cement, pharmaceutical, and phosphate industries. When efforts to offer tax incentives and attract outside investments yielded no tangible results, he nationalized more companies and made them a part of his economic development organization. In September, Turkish troops massed along the Syrian border, giving credence to rumors that the Baghdad Pact countries were attempting to topple Syria's leftist government. Nasser initially turned down the request, citing the two countries' incompatible political and economic systems, lack of contiguity, the Syrian military's record of intervention in politics, and the deep factionalism among Syria's political forces. Nasser subsequently opted for union, albeit on the condition that it would be a total political merger with him as its president, to which the delegates and Syrian president Shukri al-Quwatli agreed. On 1 February, the United Arab Republic (UAR) was proclaimed and, according to Dawisha, the Arab world reacted in "stunned amazement, which quickly turned into uncontrolled euphoria." Nasser ordered a crackdown against Syrian communists, dismissing many of them from their governmental posts.

North Yemen joined the UAR to form the United Arab States, a loose confederation.]]

On a surprise visit to Damascus to celebrate the union on 24 February, Nasser was welcomed by crowds in the hundreds of thousands. Crown Prince Imam Badr of North Yemen was dispatched to Damascus with proposals to include his country in the new republic. Nasser agreed to establish a loose federal union with Yemen—the United Arab States—in place of total integration. While Nasser was in Syria, King Saud planned to have him assassinated on his return flight to Cairo. On 4 March, Nasser addressed the masses in Damascus and waved before them the Saudi check given to Syrian security chief and, unbeknownst to the Saudis, ardent Nasser supporter Abdel Hamid Sarraj to shoot down Nasser's plane. As a consequence of Saud's plot, he was forced by senior members of the Saudi royal family to informally cede most of his powers to his brother, King Faisal, a major Nasser opponent who advocated pan-Islamic unity over pan-Arabism.

A day after announcing the attempt on his life, Nasser established a new provisional constitution proclaiming a 600-member National Assembly (400 from Egypt and 200 from Syria) and the dissolution of all political parties.

With the establishment of the United Arab Republic, the United States under President Eisenhower attempted to build better relations and initiate a rapprochement between the two countries, contrasting with the previously cautious stance of the American government towards Nasser. However, due to major ideological differences, no significant long-term working relationship developed between Nasser and Eisenhower.
