So for some time I've found the Ethiopian Empire and its Solomonic dynasty. This is the sole African nation to become and remain Christian up till the present day and the only "native" nation to defeat a colonial power. However, thanks to the fall of Egypt to Islam in the early 7th century and the eventual fall of the Ethiopian ports to the Ottoman Empire, communication between this nation and the rest of Christendom. So my question/idea is this; what if Ethiopia (including the predecessor Kingdoms) remained in close contact with the rest of Christendom, in both Europe and the Byzantine Empire.
What role could Ethiopia play in the great challenges of Christendom with close relations with the rest of the Christian world? An Ethiopian invasion of Egypt during the Crusades? Support for the Crusader states and later Byzantium against the Turks? Early racial equality/tolerance? Marriage alliances with Europe? A role in the Renaissance and reformation? Basically what would the long term affects of Ethiopia having a major role in the history of Christendom?
