Muhammad Anwar es-Sadat (25 December 1918 – 6 October 1981) was an Egyptian politician and military officer who served as the third president of Egypt, from 15 October 1970 until his assassination by members of the Egyptian Islamic Jihad on 6 October 1981. Sadat was a senior member of the Free Officers who overthrew King Farouk I in the Egyptian Revolution of 1952, and a close confidant of President Gamal Abdel Nasser, under whom he served as vice president twice and whom he succeeded as president in 1970. In 1978, Sadat and Menachem Begin, Prime Minister of Israel, signed a peace treaty in cooperation with United States President Jimmy Carter, for which they were recognized with the Nobel Peace Prize.

In his 11 years as president, he changed Egypt's trajectory, departing from many political and economic tenets of Nasserism, reinstituting a multi-party system, and launching the Infitah economic policy. As President, he led Egypt in the Yom Kippur War of 1973 to regain Egypt's Sinai Peninsula, which Israel had occupied since the Six-Day War of 1967, making him a hero in Egypt and, for a time, the wider Arab world. Afterwards, he engaged in negotiations with Israel, culminating in the Camp David Accords and the Egypt–Israel peace treaty.

Although reaction to the treaty – which resulted in the return of Sinai to Egypt – was generally favorable among Egyptians, it was rejected by the country's Muslim Brotherhood and the left, which felt Sadat had abandoned efforts to ensure a State of Palestine. With the exception of Sudan, the Arab world and the Palestine Liberation Organization (PLO) strongly opposed Sadat's efforts to make a separate peace with Israel without prior consultations with the Arab states. His refusal to reconcile with them over the Palestinian issue resulted in Egypt being suspended from the Arab League from 1979 to 1989. The peace treaty was also one of the primary factors that led to his assassination; on 6 October 1981, militants led by Khalid Al-Islambuli opened fire on Sadat with automatic rifles during the 6 October parade in Cairo, killing him.

Anwar Sadat was born on 25 December 1918 in Mit Abu El Kom, part of Monufia Governorate in what was then the Sultanate of Egypt, to a poor family, and he had 14 siblings. One of his brothers, Atef Sadat, later became a pilot and was killed in action in 1973 during the Yom Kippur War. His father, Anwar Mohammed El Sadat, was an Upper Egyptian, and his mother, Sit Al-Berain, was born to an Egyptian mother and a Sudanese father.

He graduated from the Royal Military Academy in Cairo, the capital of what was then the Kingdom of Egypt, in 1938 and was appointed to the Signal Corps. He entered the army as a second lieutenant and was posted to the Anglo-Egyptian Sudan (the Sudan being a condominium under joint British and Egyptian rule at the time). There, he met Gamal Abdel Nasser, and along with several other junior officers they formed the Free Officers, an organization committed to overthrowing British rule in Egypt and eliminating state corruption.

During World War II, Sadat, a member of the fascist and ultranationalist Young Egypt Party, collaborated with Nazi Germany in Egypt as part of Operation Salam. There were meetings and talk amongst some pro-Axis junior officers of a potential revolt, and Sadat later said that he'd wanted to make Egypt "a second Iraq". After the Abdeen Palace incident, Sadat furthered his plans for a coup, but Muslim Brotherhood leader Hassan al-Banna declined to support the plot. He then met with two German agents in Cairo to discuss his plan, but was arrested and imprisoned for much of the war. By the end of the conflict, Sadat had already met with the secret society that decided to assassinate Amin Osman, Minister of Finance in the Wafd Party government, and the head of the Egyptian-British Friendship Society, due to his strong sympathies towards the British. Osman was assassinated in January 1946. Following the assassination of Amin Osman, Sadat returned again and finally to prison.

In Qarmidan prison, he faced the most difficult ordeals of imprisonment by being held in solitary confinement, but the first accused in the Hussein Tawfiq case, escaped, and after there is no criminality evidence all the charges fall and the suspected went free. Salah Zulfikar, then young police officer, at that time was the officer in charge in the prison. He believed in his heart of Sadat's heroism and that he played a patriotic role towards his country and that he was convicted and imprisoned because of his love for his country. Zulfikar brought with him food, newspapers and cigarettes and helped his family a lot in obtaining visitor permits to check on him. Anwar Sadat was active in many political movements, including the Muslim Brotherhood, the fascist Young Egypt Party, the pro-Axis and pro-Royalist Iron Guard of Egypt, and the secret military group called the Free Officers. Along with his fellow Free Officers, Sadat participated in the military coup that launched the Egyptian Revolution of 1952, which overthrew King Farouk I on 23 July of that year. Sadat gave the first statement of the revolution over the radio to the Egyptian people.

During the presidency of Gamal Abdel Nasser, Sadat was appointed minister of State in 1954. He was also appointed editor of the newly founded daily Al Gomhuria. In 1959, he assumed the position of secretary to the National Union. Sadat was the president of the National Assembly (1960–1968) and then Vice President of Egypt and member of the presidential council in 1964. He was reappointed as vice president again in December 1969.
