Yes, an interesting fact is is that a letter from Henry IV of England to the Emperor of Abyssinia still survives! Also, in 187 and 1876, Turkish/Egyptian forces accompanied by many European and American advisors invaded Abyssinia twice, but were initially defeated. 
 I'm sorry, at the moment I don't have any geography information, but some history information did just now come up. Around the 8th century BC, a kingdom known as D'mt was established in Tigray, northern Ethiopia, and Entrea. 
 Do you have more interesting facts? 
 Can you tell me about the geography? 
 Can you tell me about Ethiopia?
