Sadat's assassins were arrested, put on trial and executed, while the death of the President led to Vice President Hosni Mubarak becoming the premier just eight days after the assassination. He went on to rule for almost 30 years before he stepped down during the 2011 Egyptian Revolution.
Three years before his assassination, Sadat had signed the Camp David Accords and jointly received the Nobel Peace Prize with Israeli Prime Minister Menachem Begin.
The Accords led to Egypt signing the Egypt–Israel Peace Treaty in 1979, which marked the first time that an Arab nation had formally recognised Israel.
Although the treaty ended 40 years of almost continuous war between the two nations, it was met with hostility by some people in Egypt who felt that Sadat had betrayed the Palestinian cause and the honour or Egypt.
With hostility to his rule growing at home, Sadat was surrounded by security as he observed the 6th October parade that marked the Egyptian crossing of the Suez Canal at the start of the Yom Kippur War.
The assassins were in the procession on board an artillery truck that stopped directly in front of Sadat and allowed them to approach the President.
Believing that this was part of the proceedings, Sadat stood to salute them but was killed in a hail of grenades and indiscriminate firing of AK-47s. He died in hospital two hours later.
