Situated in eastern Africa, Ethiopia (formerly called Abyssinia) has an area of approximately 1,127,127 sq km (435,186 sq mi), with a length of 1,639 km (1,018 mi) E – W and a width of 1,577 km (980 mi) N – S . Comparatively, the area occupied by Ethiopia is slightly less than twice the size of the state of Texas. It is bounded on the N by Eritrea, on the NE by Djibouti, on the E and SE by Somalia, on the S by Kenya, and on the W by Sudan, with a total boundary length of 5,328 km (3,311 mi). The Ogaden region of eastern Ethiopia is claimed by Somalia and has been the subject of sporadic military conflict between the two nations since 1961; the southeastern boundary has never been demarcated. Ethiopia's capital city, Addis Ababa, is located near the center of the country.
