The Ethiopian Empire was transformed under Emperor Menelik: the major signposts of modernisation with the help of key ministerial advisors, such as Gäbre-Heywät Baykädañ, were put in place. Externally, Menelik led Ethiopian troops against Italian invaders in the First Italo-Ethiopian War; following a decisive victory at the Battle of Adwa, recognition of Ethiopia's independence by external powers was expressed in terms of diplomatic representation at his court and delineation of Ethiopia's boundaries with the adjacent colonies. Menelik expanded his realm to the south and east, into Oromo, Kaffa, Sidama, Wolayta and other kingdoms or republics. He is widely called "Emiye Menelik" in Ethiopia.
