Flags of Eritrea

State of Eritrea

Who & why: the Eritrean People's Liberation Front (EPLF) takes Asmara in May 1991, ending the war and effectively securing independence; a UN-supervised referendum in April 1993 confirms it almost unanimously, and Eritrea is formally recognized as a sovereign state under President Isaias Afwerki, the EPLF's own leader. A further border war with Ethiopia from 1998-2000 costs tens of thousands of lives before a fragile peace, only fully normalized in 2018.

What it represents: the current flag, which Wikipedia says was first officially hoisted on 24 May 1993 and standardised on 5 December 1995, reworks the EPLF's own flag: a red triangle from the hoist, for the blood shed in the independence struggle, with a gold olive wreath in place of the EPLF's star, flanked by a green triangle (agriculture and livestock) above and a blue triangle (the sea) below. A remark on Flags of the World that the wreath echoes the United Nations emblem is hearsay; the sources read record no official meaning for the wreath.

Federation with, then annexation by, Ethiopia

Who & why: a UN resolution federates Eritrea with Ethiopia in 1952, granting it its own parliament, flag, and autonomy under the Ethiopian crown — a real, distinct political arrangement, not outright annexation. That autonomy erodes steadily through the 1950s, and in 1962 Emperor Haile Selassie unilaterally dissolves the federation and annexes Eritrea outright as an ordinary Ethiopian province, triggering the Eritrean War of Independence from 1961 (technically beginning just before the formal annexation). The war runs three full decades, fought first against the imperial army and then, after 1974, against the Derg's much larger forces, before the EPLF's final military victory in 1991.

What it represents: Wikipedia and Flags of the World say that in the federation of 1952 Eritrea had its own blue flag (olive branches in Wikipedia, a green wreath on light blue in Flags of the World), which Haile Selassie banned at the annexation in 1962; Flags of the World adds that it stayed a flag of the liberation struggle to 1993. Flags of the World describes the Ethiopian imperial flag as a green-yellow-red tricolour, with the Lion of Judah version as the state flag and the plain tricolour as the national flag, and the Derg using the plain tricolour. The tricolour with the lion drawn here is therefore documented only for the state flag of Ethiopia and not for the whole of 1952 to 1993.

British Military Administration

Who & why: British and Commonwealth forces defeat the Italian colonial garrison in Eritrea during the East African Campaign of 1941, ending Italian rule; Britain then administers the territory as a military occupation while its final status is debated internationally through the late 1940s, ultimately resolved by the UN's 1950 decision to federate Eritrea with Ethiopia, implemented in 1952.

What it represents: the Union Flag, flown as the administering authority's own flag over the military administration, without a distinct Eritrean territorial flag during this interim decade. FOTW says the British took over after the Battle of Keren in 1941 and that British administration ended in 1951 (not 1952); Wikipedia mentions British rule from 1949 under a UN mandate. Neither describes a flag used in this period.

Italian Eritrea

Who & why: Italy formally proclaims the colony of Eritrea in January 1890, its first colony anywhere in Africa, consolidating earlier footholds at Assab (bought in 1869) and Massawa (occupied 1885), and administers it from the highland city of Asmara. Eritrea later serves as Italy's staging ground for the 1935-36 invasion of Ethiopia and is folded into Italian East Africa from 1936 alongside occupied Ethiopia and Italian Somaliland, before British forces end Italian rule in 1941.

What it represents: the Kingdom of Italy's own tricolor, typically flown with a colonial governorate badge for official use; shown here in schematic form representing Italian civil administration of the colony. FOTW says Eritrea became an Italian colony on 1 January 1890 and a province of Italian East Africa in 1936; neither source describes a flag used in the colony.

Red Sea coastal sultanates & highland peoples

Who & why: before Italian colonization, the Eritrean coast passes through Ottoman and later Egyptian nominal control at trading ports like Massawa, while the highlands remain closely tied to the neighboring Ethiopian state and its own Tigrayan provinces, and lowland peoples live under local sultanates and clan structures. No single unified Eritrean polity exists before the Italian colonial boundary is drawn.

What it represents: no securely documented unified flag survives for this era. Shown here honestly blank rather than invented.

Kingdom of Aksum & the Port of Adulis

Who & why: centuries before any Ottoman, Egyptian, or Italian presence on the Eritrean coast, the port of Adulis anchored the Kingdom of Aksum's trade with the wider ancient world, making Aksum — centered in the highlands of modern Ethiopia and Eritrea — one of the major powers of late antiquity; a 3rd-century Persian text ranks it alongside Rome, Persia, and China as one of the four great kingdoms of the age. King Ezana's 4th-century conversion to Christianity and Aksum's own minted coinage, gold, silver, and bronze, are both securely attested by surviving inscriptions and archaeology. Aksum's decline from the 7th–8th centuries, amid shifting trade routes and the rise of Islam in Arabia, leaves the fragmented, multi-power era described in the next entry.

What it represents: no state flag survives from Aksum or Adulis in any form comparable to a modern national flag; Aksumite kings are instead documented through towering carved stone stelae, minted coinage bearing royal portraits, and inscriptions in Ge'ez, Greek, and Sabaean. Shown here honestly blank rather than invented.

World context: Adulis's heyday as a Red Sea entrepôt runs alongside the Roman Empire's height and the Periplus of the Erythraean Sea's 1st-century account of Indian Ocean trade, while Ezana's 4th-century conversion to Christianity comes shortly before Emperor Constantine's own embrace of Christianity in Rome; Aksum's later decline coincides with the rapid 7th-century rise of Islam across Arabia just across the Red Sea.
