Isolated Freak, your views about the nations by 2100 AD seem logical, though I would expect more detailed and regional explanations of your arguments later. For now, I am presenting a brief history and formation of Eritrea. Eritrea is one of the newest nations of the world, which gained independence only in April 27th,1993 from Ethiopia, after 30 years of bitter struggle. Between 1000 and 400 BC, a group of people called Sabeans crossed the Red Sea and intermingled with the Hamitic population, who had migrated from Northern Sudan. Throughout history, it bacame ruled by several foreign forces like the Axumite kingdom, the Funji Sultans of Sudan, the Egyptians, the Portugese and the Turks. In the modern era, Italy colonised Eritrea from 1880 to 1941 until Italy was defeated in World War II. The King of Italy, by issuing a decree on 1st January 1890,had declared Eritrea a colony of Italy. Italy built many infrastructures in Eritrea which were necessary for the Italians to settle down. Railway lines, airports and roads were built in the capital Asmara and other cities. The transportation and communication facilities were among the best in Africa during that era. However, as Italy was under a fascist rule, its rule in Eritrea was not benign, treating the Eritreans as a cheap source of labour for the self-interest of Rome. After Italy knelt down in the second world war, Great Britain was given the charge of ruling Eritrea. As a result, British Military Administration (BMA) ruled Eritrea as "Occupied Enemy Territory". Meanwhile, Ethiopia was claiming Eritrea through intervention and diplomatic efforts.The newly reinstated Emperor of Ethiopia started to gain influence in Eritrea by using the tactics of interference in the religious affairs, manipulation of the political parties and terrorism. The formal armed war of Eritrea against Ethiopia started in 1961, which in thirty years, Eritrean People's Liberation Front (EPLF), was able to win by 1991.In 1993, the UN sponsored referendum for Independence of Eritrea was held on April 23rd to 25th, in which 99% votes were cast for independence.
