The PDRE's limited ability to lead development and to respond to crises was dramatically demonstrated by the government's reliance on foreign famine relief between 1984 and 1989. By 1983 armed conflict between the government and opposition movements in the north had combined with drought to contribute to mass starvation in Eritrea, Tigray, and Welo. Meanwhile, drought alone was having a devastating impact on an additional nine regions. This natural disaster far exceeded the drought of 1973-74, which had contributed to the downfall of Emperor Haile Selassie. By early 1985, some 7.7 million people were suffering from drought and food shortages. Of that number, 2.5 million were at immediate risk of starving.
