Muhammad Anwar el-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 fundamentalist army officers on 6 October 1981. Sadat was a senior member of the Free Officers who overthrew King Farouk 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 eleven years as president, he changed Egypt's trajectory, departing from many of the political and economic tenets of Nasserism, re-instituting 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 EgyptIsrael peace treaty; this won him and Menachem Begin the Nobel Peace Prize, making Sadat the first Muslim Nobel laureate. Although reaction to the treatywhich resulted in the return of Sinai to Egyptwas 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 Palestinian state. 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 Islambouli opened fire on Sadat with automatic rifles during the 6 October parade in Cairo, killing him.

Egypt (Arabic: مِصر, romanized: Miṣr), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia by a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip (Palestine) and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast, whose maximum width is 24 km (15 mi), separates Egypt from Jordan and Saudi Arabia. Cairo is the country's capital and largest city.

Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, urbanisation, organised religion and central government. Iconic monuments such as the Giza Necropolis and its Great Sphinx, as well the ruins of Memphis, Thebes, Karnak, and the Valley of the Kings, reflect this legacy and remain a significant focus of scientific and popular interest. Egypt's long and rich cultural heritage is an integral part of its national identity, which reflects its unique transcontinental location being simultaneously Mediterranean, Middle Eastern and North African. Egypt was an early and important centre of Christianity, but was largely Islamised in the seventh century and remains a predominantly Muslim country, albeit with a significant Christian minority.

Modern Egypt dates back to 1922, when it gained independence from the British Empire as a monarchy. Following the 1952 revolution, Egypt declared itself a republic, and in 1958 it merged with Syria to form the United Arab Republic, which dissolved in 1961. Throughout the second half of the 20th century, Egypt endured social and religious strife and political instability, fighting several armed conflicts with Israel in 1948, 1956, 1967 and 1973, and occupying the Gaza Strip intermittently until 1967. In 1978, Egypt signed the Camp David Accords, officially withdrawing from the Gaza Strip and recognising Israel. The country continues to face challenges, from political unrest, including the recent 2011 revolution and its aftermath, to terrorism and economic underdevelopment. Egypt's current government, a semi-presidential republic led by Abdel Fattah el-Sisi, has been described by a number of watchdogs as authoritarian or heading an authoritarian regime, responsible for perpetuating the country's problematic human rights record.

Islam is the official religion of Egypt and Arabic is its official language. With over 100 million inhabitants, Egypt is the most populous country in North Africa, the Middle East, and the Arab world, the third-most populous in Africa (after Nigeria and Ethiopia), and the fourteenth-most populous in the world. The great majority of its people live near the banks of the Nile River, an area of about 40,000 square kilometres (15,000 sq mi), where the only arable land is found. The large regions of the Sahara desert, which constitute most of Egypt's territory, are sparsely inhabited. About half of Egypt's residents live in urban areas, with most spread across the densely populated centres of greater Cairo, Alexandria and other major cities in the Nile Delta.

Egypt is considered to be a regional power in North Africa, the Middle East and the Muslim world, and a middle power worldwide. It is a developing country, ranking 116th on the Human Development Index. It has a diversified economy, which is the second-largest in Africa, the 33rd-largest economy by nominal GDP, and the 20th-largest globally by PPP. Egypt is a founding member of the United Nations, the Non-Aligned Movement, the Arab League, the African Union, Organisation of Islamic Cooperation and the World Youth Forum.
