Emperor Téwodros II (Ge’ez: ቴዎድሮስ, baptized as Sahle Dingil) (c. 1818 – April 13, 1868) was the Emperor of Ethiopia from 1855 until his death. Born Kassa Haile Giorgis, but was more regularly referred to as Kassa Hailu (Ge’ez: ካሳ ኃይሉ — meaning “restitution” and “His [or the] power”). His rule is often placed as the beginning of modern Ethiopia, ending the decentralized Zemene Mesafint (Era of the Princes).
