“ Introduction Eritrea Background: Eritrea was awarded to Ethiopia in 1952 as part of a federation. Ethiopia's annexation of Eritrea as a province 10 years later sparked a 30-year struggle for independence that ended in 1991 with Eritrean rebels defeating governmental forces; independence was overwhelmingly approved in a 1993 referendum. A two-and-a-half-year border war with Ethiopia that erupted in 1998 ended under UN auspices on 12 December 2000. Eritrea currently hosts a UN peacekeeping operation that is monitoring a 25 km-wide Temporary Security Zone on the border with Ethiopia. ”
