The Ethiopian Empire
The Ethiopian Empire also known as Abyssinia, covered a geographical area that the present-day northern half of Ethiopia covers. It existed from approximately 1137 (beginning of Zagwe Dynasty) until 1975 when the monarchy was overthrown in a coup d’état. In 1270, the Zagwe dynasty was overthrown by a king claiming lineage from the Aksumite emperors and, hence, Solomon. The thus-named Solomonic Dynasty was founded and ruled by the Habesha, from whom Abyssinia gets it's name.
The Habesha reigned with only a few interruptions from 1270 until the late 20th century. It was under this dynasty that most of Ethiopia’s modern history occurred. During this time, the empire conquered and incorporated virtually all the peoples within modern Ethiopia. They successfully fought off Italian, Arab and Turkish armies and made fruitful contacts with some European powers, especially the Portuguese, with whom they allied in battle against the latter two invaders.
