Ethiopia / ቴዎድሮስ (Emperor Tewodros II)

Tewodros II (Ge'ez: ቴዎድሮስ, baptized as Sahle Dingil, and often referred to in English by the equivalent Theodore II) was the Emperor of Ethiopia from 1855 until his death.

He was 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).
