Eritrea in the context of "Khedivate of Egypt"

Northeast Africa, or Northeastern Africa, or Northern East Africa as it was known in the past, encompasses the countries of Africa situated in and around the Red Sea. The region is intermediate between North Africa and East Africa, and encompasses the Horn of Africa (Djibouti, Eritrea, Ethiopia, and Somalia), as well as Sudan, Libya,and Egypt in addition to, although rarely, South Sudan. The region has a very long history of habitation with fossil finds from the early hominids to modern human and is one of the most culturally and linguistically diverse regions of the world, being the home to many civilizations and located on an important trade route that connects multiple continents; Gamal Abdel Nasser, the second president of Egypt (which is the most northeastern African country) once described it as "the crossroads of the world, the thoroughfare of its traders and passageway of its armies."

The Nile (also known as the Nile River or River Nile) is an important river in Africa that flows northwards into the Mediterranean Sea. At roughly 6,650 km (4,130 mi) long, it is among the longest rivers in the world. Its drainage basin covers eleven countries: the Democratic Republic of the Congo, Tanzania, Burundi, Rwanda, Uganda, Kenya, Ethiopia, Eritrea, South Sudan, Sudan, and Egypt. It plays an important economic role in the economy of these nations, and it is the primary water source for South Sudan, Sudan and Egypt.

The Nile has two major tributaries: the White Nile and the Blue Nile. The White Nile, being the longer, is traditionally considered to be the headwaters, while the Blue Nile actually contributes 80% of the water and silt below the confluence of the two. The White Nile begins at Lake Victoria and flows through Uganda and South Sudan, while the Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet at the Sudanese capital of Khartoum.

Somali literature is the literature used by the ethnic Somalis of Somalia, Somaliland, Djibouti, Yemen, Eritrea, Ethiopia, and Kenya.

Sudan, officially the Republic of the Sudan, is a country in Northeast Africa. It borders the Central African Republic to the southwest, Chad to the west, Libya to the northwest, Egypt to the north, the Red Sea to the east, Eritrea and Ethiopia to the southeast, and South Sudan to the south. Sudan has a population of 50 million people as of 2024 and occupies 1,886,068 square kilometres (728,215 square miles), making it Africa's third-largest country by area. Sudan's capital and most populous city is Khartoum.

The area that is now Sudan witnessed the Khormusan (c. 40000–16000 BC), Halfan culture (c. 20500–17000 BC), Sebilian (c. 13000–10000 BC), Qadan culture (c. 15000–5000 BC), the war of Jebel Sahaba, the earliest known war in the world, around 11500 BC, A-Group culture (c. 3800–3100 BC), Kingdom of Kerma (c. 2500–1500 BC), the Egyptian New Kingdom (c. 1500–1070 BC), and the Kingdom of Kush (c. 785 BC – 350 AD). After the fall of Kush, the Nubians formed the three Christian kingdoms of Nobatia, Makuria, and Alodia. Between the 14th and 15th centuries, most of Sudan was gradually settled by Arab nomads. From the 16th to the 19th centuries, central and eastern Sudan were dominated by the Funj sultanate, while Darfur ruled the west and the Ottomans the east.

Yemen, officially the Republic of Yemen, is a country in West Asia. Including the Socotra Archipelago, mainland Yemen is located in southern Arabia; bordering Saudi Arabia to the north, Oman to the northeast, the south-eastern part of the Arabian Sea to the east, the Gulf of Aden to the south, and the Red Sea to the west, sharing maritime borders with Djibouti, Eritrea, and Somalia across the Horn of Africa. Covering roughly 455,503 square kilometres (175,871 square miles), with a coastline of approximately 2,000 kilometres (1,200 miles), Yemen is the second largest country on the Arabian Peninsula. Sanaa is its constitutional capital and largest city. Yemen's estimated population is 34.7 million, mostly Arab Muslims. It is a member of the Arab League, the United Nations, the Non-Aligned Movement and the Organisation of Islamic Cooperation.

Owing to its geographic location, Yemen has been at the crossroads of many civilisations for over 7,000 years. The Sabaeans formed a thriving commercial kingdom that influenced parts of modern Ethiopia and Eritrea. In 275 CE, it was succeeded by the Himyarite Kingdom, which spanned much of Yemen's present-day territory and was heavily influenced by Judaism. Christianity arrived in the fourth century, followed by the rapid spread of Islam in the seventh century. From its conversion to Islam, Yemen became a center of Islamic learning, and Yemenite troops played a crucial role in early Islamic conquests. Much of Yemen's architecture survived until modern times. For centuries, it was a primary producer of coffee, exported through the port of Mocha. Various dynasties emerged between the 9th and 16th centuries. During the 19th century, the country was divided between the Ottoman and British empires. After World War I, the Kingdom of Yemen was established, which in 1962 became the Yemen Arab Republic (North Yemen) following a civil war. In 1967, the People's Democratic Republic of Yemen (South Yemen) gained its independence from the British Aden Protectorate, becoming the first and only communist state in the Middle East and the Arab world. In 1990, the two Yemeni states united to form the modern Republic of Yemen, with Ali Abdullah Saleh serving as the first president until his resignation in 2012 in the wake of the Arab Spring.

The Oriental Orthodox Churches are Eastern Christian churches adhering to Miaphysite Christology, with approximately 60 million members worldwide. However, the Oriental Orthodox Churches, individually, claim approximately 87 million baptized members. The Oriental Orthodox Churches adhere to the Nicene Christian tradition. Oriental Orthodoxy is one of the oldest branches in Christianity.

As some of the oldest religious institutions in the world, the Oriental Orthodox Churches have played a prominent role in the history and culture of countries and regions such as Armenia, Egypt, Eritrea, Ethiopia, Sudan, the Levant, Iraq and the Malabar region of southern India. As autocephalous churches, their bishops are equal by virtue of episcopal ordination. Their doctrines recognize only the first three ecumenical councils as valid.

Ethiopia, officially the Federal Democratic Republic of Ethiopia, is a landlocked country located in the Horn of Africa region of East Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia covers a land area of 1,104,300 square kilometres (426,400 sq mi). As of 2025, it has around 135 million inhabitants, making it the 14-most populous country. The national capital and largest city, Addis Ababa, lies several kilometres west of the East African Rift that splits the country into the African and Somali tectonic plates.

Anatomically modern humans emerged from modern-day Ethiopia. In 980 BC, the Kingdom of D'mt extended its realm over Eritrea and the northern region of Ethiopia, while the Kingdom of Aksum maintained a unified civilization in the region for 900 years. Christianity was embraced by the kingdom in 330, and Islam arrived by the first Hijra in 615. After the collapse of Aksum in 960, the Zagwe dynasty ruled the north-central parts of Ethiopia until being overthrown by Yekuno Amlak in 1270, inaugurating the Ethiopian Empire and the Solomonic dynasty, claimed descent from the biblical Solomon and Queen of Sheba under their son Menelik I. By the 14th century, the empire had grown in prestige through territorial expansion and fighting against adjacent territories; most notably, the Ethiopian–Adal War (1529–1543) contributed to fragmentation of the empire, which ultimately fell under a decentralization known as Zemene Mesafint in the mid-18th century. Emperor Tewodros II ended Zemene Mesafint at the beginning of his reign in 1855, marking the reunification and modernization of Ethiopia.

The Bab-el-Mandeb (Arabic: باب المندب, lit. 'Gate of Grief/Tears') is a strait between Yemen on the Arabian Peninsula and Djibouti and Eritrea in the Horn of Africa, connecting the Red Sea to the Gulf of Aden and by extension the Indian Ocean.
