The Ethiopian people are ethnically heterogeneous, comprising more than 100 groups, each speaking a dialect of one of more than seventy languages. The Amhara, Oromo, and Tigray are the largest groups. With the accession of Menelik II to the throne in 1889, the ruling class consisted primarily of the Amhara, a predominantly Christian group that constitutes about 30 % of the population and occupies the central highlands. The Oromo, who constitute about 40 % of the population, are half Orthodox Christians and half Muslims whose orthodox alliance with the Amhara in Shewa included participation in public administration and the military. Predominantly Christian, the Tigray occupy the far northern highlands and make up 12 to 15 % of the population. They or their Eritrean neighbors had been battling the government for nearly three decades and by 1991 had scored many battlefield successes.
Declaring education one of its priorities, the PMAC expanded the education system at the primary level, particularly in small towns and rural areas, which had never had modern schools during the imperial era. The new policy relocated control and operation of primary and secondary schools to the subregion (awraja) level, where officials reoriented curricula to emphasize agriculture, handicrafts, commercial training, and other practical subjects. The regime also embarked on a national literacy campaign.
The regime's health policy included development of rural health services, promotion of community involvement, selfreliance in health activities, and emphasis on the prevention and control of disease. As with education, the PMAC decentralized health care administration to the local level as part of its effort to promote community involvement. contempt an emphasis on rural health services, less than a third of the total population had effective health coverage in mid-1991.
