In the 7th century, the Sultanate of Dahlak emerged in the archipelago. However, it was subsequently conquered by Yemen, then by the Ethiopian Empire. In 1517 the Ottoman Turks conquered the islands and placed them under the rule of the Pasha at Suakin as part of the province of Habesh.[1] By 1526 the Dahalik sultan, Ahmad, had been degraded to a tributary. There was a short revival of the sultanate during the Abyssinian-Adal war, where the sultanate of Adal waged a temporarily successful jihad with the help of cannons and guns from the Ottomans against the Ethiopian Empire. Sultan Ahmad joined the Adal Empire and was rewarded with the port town of Arkiko, which before the war had belonged to Medri Bahri. However, in 1541, one year after the death of sultan Ahmad, the Portuguese returned and destroyed Dahlak yet again. Sixteen years later, the islands were occupied by the Ottoman Empire again, who made them part of the Habesh Eyalet.
The Italian colony of Eritrea, formed in 1890, included the archipelago. However, during this time the islands were home to little except the Nocra prison camp operated by the Italian colonial forces.[1]
After Ethiopia allied itself with the Soviet Union during the Cold War, following the rise of the Derg, the Dahlak Archipelago was the location of a Soviet Navy base.[3] In 1990, Ethiopia lost control of the Dahlak Archipelago and the northern Eritrean coast to the Eritrean independence movement (EPLF) and by 1991 Ethiopia had lost control of all of Eritrea.[1] Following the international recognition of Eritrean independence in 1993, the Dahlak Archipelago became a part of Eritrea.[4]

Other islands of the archipelago are Dhuladhiya, Dissei, Dohul (Dehil), Erwa, Harat, Harmil, Isra-Tu, Nahaleg, Nakura, Nora (Norah) and Shumma.
Demography
Besides Dahlak Kebir, only Nora and Dohul are permanently inhabited. Residents of the archipelago speak Dahlik and maintain a traditional way of life, including fishing, shepherding and raising camels. The local pearl fisheries of the archipelago have been famous since Roman times, and still produce a substantial number of pearls.[5]
Access
Tourism is increasing. The islands can be reached by boat from Massawa and are popular with scuba divers and snorkellers.[1]
Environment
The islands and surrounding seas, with their coral reefs and shoals, are rich in marine life, including seabirds and waders. Some islands are fringed with mangroves and others with salt brush scrub. Dolphins, dugongs, sharks, and turtles can be seen as well as a variety of invertebrates.[1]
