In the later part of the 20th century, several wars were waged in the region, including the Ethiopian Civil War (1974–1991), the Ogaden War (1977–1978), the Eritrean War of Independence (1961–1991), and the Eritrean-Ethiopian War (1998–2000). During its socialist period, Somalia had the largest military on the continent on account of its friendship with the Soviet Union and later partnership with the United States. The subsequent outbreak of the Somali Civil War in 1991 led to the disbandment of the Somali National Army (SNA). However, the armed forces were later gradually reconstituted with the establishment of the Transitional Federal Government (TFG) in 2004.
