Location	Red Sea
Archipelago	Bab-el-Mandeb

Hanish Islands are an archipelago in the southern Red Sea near the entrance to the Gulf of Aden, strategically positioned off the coasts of Yemen and Eritrea. The islands have been the focus of international attention due to periodic disputes involving Yemen and Eritrea, decisions by the International Court of Justice, and their proximity to major maritime routes connecting the Suez Canal and the Indian Ocean. The islands' geology, ecology, and human use reflect influences from neighboring regions such as the Horn of Africa, the Arabian Peninsula, and historical maritime networks linking Aden, Massawa, and Djibouti.

Geography

The archipelago lies in the southern sector of the Red Sea near Bab-el-Mandeb strait and comprises several islands including Greater Hanish, Smaller Hanish, and nearby islets and reefs such as Sanaag features; they are situated approximately between Perim Island and The Farasan Islands and close to the continental margins of Yemen and Eritrea. The islands are underlain by Red Sea Rift tectonics, associated with the Afar Depression and the broader East African Rift system, producing basaltic outcrops, coral reefs, and emerged lava fields characteristic of rift-related volcanism seen also on Socotra and Hanish-adjacent shoals. Oceanographically, the islands sit within currents connecting the Gulf of Aden and Red Sea, influenced by the seasonal Monsoon system that also affects navigation to Aden and Djibouti.

History

Human interaction with the islands is attested in maritime sources linking ancient ports such as Aden, Berenice (Egypt), and Ostia through Red Sea trade routes; medieval navigators from Hadhramaut, Zanzibar, and Kilwa Kisiwani frequented the waters. Ottoman records from the Ottoman–Portuguese conflicts (16th century) and later British Empire charts during the era of the British Aden Protectorate reference the archipelago as waypoints for caravans and naval operations. In the 20th century the islands featured in colonial-era mapping by the Italian Empire in Eritrea and were cited in diplomatic correspondence involving United Kingdom consular offices in Aden and Asmara. The late 20th and early 21st centuries saw renewed prominence during incidents involving Yemen Civil War (1994) aftermath, the Eritrean–Ethiopian War, and disputes adjudicated by the International Court of Justice.

Sovereignty and Territorial Disputes

Sovereignty over the islands became contested between Yemen and Eritrea after Eritrea gained independence from the Provisional Government of Eritrea and subsequent state formation, prompting negotiations influenced by regional actors such as Saudi Arabia and international bodies including the United Nations and the International Court of Justice. The dispute culminated in armed clashes and later legal proceedings before the ICJ, which examined colonial-era treaties, Ottoman-era claims, and documents from the British Protectorate period alongside diplomatic notes from Italy and the League of Nations mandates. The situation involved maritime delimitation questions related to the United Nations Convention on the Law of the Sea framework as well as bilateral talks mediated by envoys from Egypt, Jordan, and multilateral organizations.

Ecology and Environment

The islands host coral reef ecosystems comparable to those found around Socotra and Farasan Islands, with reef-building corals, seagrass beds, and reef-associated fish taxa documented in surveys similar to work by institutions such as the International Union for Conservation of Nature and research programs linked to Sultan Qaboos University and King Abdullah University of Science and Technology. Birdlife includes migratory species tracked along the East African–West Asian Flyway with affinities to populations recorded in Djibouti and Yemen coastal wetlands. The archipelago faces environmental pressures from marine traffic on routes to the Suez Canal and from episodic resource exploitation reflecting patterns seen in the Gulf of Aden and Red Sea regional fisheries, with conservation interests aligning with initiatives by UNEP and regional marine protected area proposals.

Economy and Infrastructure

Economic activity on the islands has historically been limited to small-scale fishing, maritime transshipment functions, and occasional resource surveys conducted by entities from Yemen, Eritrea, and international energy companies operating in the Gulf of Aden and Red Sea basins. The strategic location near shipping lanes linking the Suez Canal to the Gulf of Aden has attracted naval visits from states such as United Kingdom, United States, and regional navies from Saudi Arabia and Egypt for transit oversight and anti-piracy operations associated with the Gulf of Aden anti-piracy efforts. Infrastructure is minimal, with rudimentary landing sites referenced in hydrographic charts produced by the Admiralty and survey missions by institutions like the National Oceanic and Atmospheric Administration and maritime agencies of neighboring capitals such as Sana'a and Asmara.

Demographics and Culture

Permanent population has been sparse, with seasonal or temporary habitation linked to fishermen and occasional military or scientific personnel arriving from Yemen and Eritrea, echoing settlement patterns seen on remote Red Sea islands such as Perim Island and Hala'ib Triangle adjacent areas. Cultural connections reflect broader Arabian Peninsula and Horn of Africa exchanges, incorporating linguistic, culinary, and maritime traditions shared with communities in Aden, Massawa, Zanzibar, and coastal Oman. Religious and social practices mirror regional norms influenced by Islamic traditions prevalent in Yemen and Eritrea, and historical ties to trade diasporas that connected the islands to ports across the Indian Ocean.
