The Red Sea (Arabic: , romanized: al-Bar al-Amar; Hebrew: -, romanized: yam sf or Hebrew: , romanized: hayym hm) is a seawater inlet of the Indian Ocean, lying between Africa and Asia. Its connection to the ocean is in the south, through the Bab el Mandeb strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal). It is underlain by the Red Sea Rift, which is part of the Great Rift Valley.

The Red Sea has a surface area of roughly 438,000 km2 (169,100 mi2), is about 2250 km (1398 mi) long, and at its widest point 355 km (220.6 mi) wide. It has an average depth of 490 m (1,608 ft), and in the central Suakin Trough it reaches its maximum depth of 3,040 m (9,970 ft).The Red Sea also has extensive shallow shelves, noted for their marine life and corals. The sea is the habitat of over 1,000 invertebrate species and 200 types of soft and hard coral. It is the world's northernmost tropical sea, and has been designated a Global 200 ecoregion.

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.
