This region once part of Ethiopia, fought for thirty years to gain independence and in May 1993, the Eritrean People's Liberation Front declared itself independent, a move recognized by the US, Sudan, and other countries, including Ethiopia. Part of the Italian empire in the beginning of the 20th century, it was ruled by Britain during World War II. Though Britain appended the area to Ethiopia in 1952, secession efforts commenced almost immediately. Though hopes were high that independence would bring all hostilities to a close, in 1995, Eritrea began to skirmish with Yemen over control of Greater Hanish Island in the Red Sea. Then, in 1998, Eritrea and Ethiopia heated up their border. This costly effort has resulted in many casualties on both sides, though the US tried to mediate. The war came to an end with a ceasefire in June 2000.
