 After a period of decentralized power in the 18th and early 19th centuries known as the Zemene Mesafint ("Era of the Judges/Princes"), the country was reunited in 1855 by Kassa Hailu, who became Emperor Tewodros II, beginning Ethiopia's modern history.
 Ethiopia's borders underwent significant territorial expansion to its modern borders for the rest of the century, especially by Emperor Menelik II and Ras Gobena, culminating in its victory over the Italians at the Battle of Adwa in 1896 with the military leadership of Ras Makonnen, and ensuring its sovereignty and freedom from colonization.
 It was brutally occupied by Benito Mussolini's Fascist Italy from 1936 to 1941, ending with its liberation by British Empire and Ethiopian Patriot forces.
