Answer
Lij Iyasu's reign ended in a coup in 1916 when he was ousted by Ras Tafari Makonnen, who later became Emperor Haile Selassie I. Iyasu's reign had been marked by conflict with the European powers that had been colonizing Ethiopia, and he was seen as being too pro-European. The coup was supported by the Ethiopian Orthodox Church, which was opposed to Iyasu's policies.
