Ethiopia
All of this led to Ethiopia's isolation during the 1700s. The Emperors became figureheads, controlled by warlords like Ras Mikael Sehul of Tigray. But Amharic is the national language of Ethiopia. Ethiopian isolationism ended following a British mission that made friendship between the two nations; however, it was not until the reign of Tewodros II that Ethiopia began to take part in world matters once again.
