Answer
Zemene Mesafint, meaning "Era of the Princes" in Amharic, was a decentralized period in Ethiopian history that lasted from the mid-18th to the mid-19th century. It was characterized by the weakening of the central government and the rise of regional warlords. Tewodros II, who ruled from 1855 to 1868, sought to put an end to this period of instability and restore the power of the central government.
