Flags of Sudan

Republic of the Sudan (modern flag)

Who & why: the current flag is adopted in 1970 under the government of Gaafar Nimeiry, following the pan-Arab red-white-black color scheme shared with Egypt, Iraq, Syria, and other Arab republics, with green added for Islam. Sudan's post-independence decades include repeated civil wars between the Arab-Muslim north and the largely Christian and animist south, culminating in South Sudan's peaceful, internationally recognized secession in July 2011 following an overwhelming independence referendum — the world's newest country, covered separately in this atlas's East Africa hub.

What it represents: a green hoist triangle for Islam and hope, over a red-white-black horizontal tricolor representing the pan-Arab colors — unchanged since 1970 despite Sudan's subsequent territorial and political upheavals.

Republic of the Sudan (independence flag)

Who & why: Sudan becomes independent on 1 January 1956 from joint British and Egyptian rule, the first sub-Saharan African colony to gain independence in the post-war wave of decolonization. Civil war between the northern and southern regions breaks out almost immediately, a conflict whose roots and consequences run through the rest of Sudan's modern history.

What it represents: a horizontal tricolor of blue (the Nile and peace), yellow (the desert), and green (fertility and the south), adopted at independence and used until a new government changes the design in 1970.

Anglo-Egyptian Sudan

Who & why: after Anglo-Egyptian forces under Lord Kitchener defeat the Mahdist State at Omdurman in 1898, an 1899 agreement establishes joint British-Egyptian rule, though Britain holds the real administrative power throughout. Growing nationalist movements after WWII lead to self-government in 1953 and full independence in 1956.

What it represents: no single condominium flag existed — the Egyptian flag and the Union Jack were flown together as the joint sovereigns' banners across this period, shown here honestly as two flags rather than one invented design.

Mahdist State

Who & why: Muhammad Ahmad declares himself the Mahdi, a redeemer figure in Islamic eschatology, and leads a successful revolt against Turco-Egyptian rule, capturing Khartoum in January 1885 (killing British general Charles Gordon in the process) and founding a genuinely independent, religiously governed Sudanese state that survives until Anglo-Egyptian reconquest in 1898.

What it represents: Ansar (Mahdist) military banners were black, white, or green fields bearing Arabic religious inscriptions and Quranic verses, varying by unit and commander — shown here as an informed reconstruction representing the black state banner most associated with the Khalifa's rule.

Turco-Egyptian Sudan

Who & why: Muhammad Ali of Egypt invades and conquers the Funj Sultanate's territory from 1820–21, incorporating Sudan into his expanding, nominally Ottoman, Egyptian state. Turco-Egyptian administration is widely resented for heavy taxation and involvement in the slave trade, grievances that help fuel the Mahdist revolt that ends this period in 1885.

What it represents: the Ottoman-Egyptian red flag with white crescent and star, the standard banner of Egyptian administration flown across Sudan during this period.

Funj Sultanate (Sennar)

Who & why: the Funj people establish the Sultanate of Sennar around 1504, an independent Islamic state controlling much of what is now central and eastern Sudan for over three centuries, until Muhammad Ali's Egyptian invasion conquers it in 1820–21.

What it represents: no securely documented state flag survives for the Funj Sultanate. Shown here honestly blank rather than invented.

Kingdom of Kush & Christian Nubian kingdoms

Who & why: the Kingdom of Kush, centered first at Napata and later at Meroë, is a genuine and significant African civilization in its own right — its rulers conquered and governed Egypt itself as its 25th dynasty (c. 744–656 BC) and the kingdom outlasted Pharaonic Egypt by centuries. Kush gives way from the 6th century AD to a trio of Christian Nubian kingdoms (Nobatia, Makuria, and Alodia), which hold out against Islamic expansion for centuries under treaty arrangements with Egypt, before gradually declining and falling to Arab and Funj pressure by the early 1500s.

What it represents: no flags in the modern heraldic sense exist from this era; Kushite and Nubian rulers used royal regalia, crowns, and religious iconography rather than territorial banners. Shown here honestly blank rather than invented, representing over 2,500 years of Nubian civilization this atlas cannot reduce to a single painted flag.

Kingdom of Kerma

Who & why: Kerma, on the Nile south of Egypt's Third Cataract, grows from the mid-3rd millennium BCE into a large fortified city and the capital of Sudan's earliest known kingdom, contemporary with and a genuine rival to Egypt's Old and Middle Kingdoms for control of Nile trade routes carrying gold, ivory, ebony, and captives from further south. Its own royal names are lost — Egyptian sources record only the polity's name, "Kush" — but its monumental tombs, including tumuli holding hundreds of sacrificed cattle and retainers, attest to a real, wealthy, centralized state. Egypt's New Kingdom finally destroys Kerma and annexes Nubia around 1500 BCE, a colonial occupation that lasts roughly four centuries until Egyptian power recedes and a new independent Kushite kingdom, covered in the entry above, re-emerges at Napata by about 1070 BCE.

What it represents: no flag survives or is plausibly attested for Kerma in any modern sense; distinctive blue-glazed faience pottery, ivory and gold jewelry, and its royal tumuli are the era's best-documented material culture. Shown here honestly blank rather than invented.

World context: Kerma's rise is roughly contemporary with the building of Egypt's Great Pyramid of Giza (c. 2560 BCE) and the Old Kingdom pyramid age, the height of Sumerian city-states in Mesopotamia, and the mature Indus Valley Civilization; its fall to Thutmose I around 1500 BCE falls within the same New Kingdom era that produces Hatshepsut and, a century later, Tutankhamun.
