After World War II, Eritrea was aligned by the UN with Ethiopia as part of a federation. This was problematic from the start, and soon a war for independence started that would last for 30 years.
Today Eritrea is a desperately poor country, with 80% of the population engaged in subsistence agriculture. Lack of religious freedom has created many refugees fleeing to Kenya. Continued border disputes with Ethiopia contribute to the instability of the country.
