Post War Ethiopia

On 27 August 1942, Haile Selassie abolished the legal basis of slavery throughout the empire and imposed severe penalties, including death, for slave trading. After World War II, Ethiopia became a charter member of the United Nations. In 1948, the Ogaden, a region disputed with Somalia, was granted to Ethiopia. On 2 December 1950, the UN General Assembly adopted Resolution 390 (V), establishing the federation of Eritrea (the former Italian colony) into Ethiopia. Eritrea was to have its own constitution, which would provide for ethnic, linguistic, and cultural balance, while Ethiopia was to manage its finances, defense, and foreign policy.

Despite his centralization policies that had been made before World War II, Haile Selassie still found himself unable to push for all the programs he wanted. In 1942, he attempted to institute a progressive tax scheme, but this failed due to opposition from the nobility, and only a flat tax was passed; in 1951, he agreed to reduce this as well. Ethiopia was still "semi-feudal", and the emperor's attempts to alter its social and economic form by reforming its modes of taxation met with resistance from the nobility and clergy, which were eager to resume their privileges in the postwar era. Where Haile Selassie actually did succeed in effecting new land taxes, the burdens were often passed by the landowners to the peasants. Despite his wishes, the tax burden remained primarily on the peasants.

Between 1941 and 1959, Haile Selassie worked to establish the autocephaly of the Ethiopian Orthodox Church. The Ethiopian Orthodox Church had been headed by the abuna, a bishop who answered to the Patriarchate in Egypt. Haile Selassie applied to Egypt's Holy Synod in 1942 and 1945 to establish the independence of Ethiopian bishops, and when his appeals were denied he threatened to sever relations with the See of St. Mark. Finally, in 1959, Pope Kyrillos VI elevated the Abuna to Patriarch-Catholicos. The Ethiopian Church remained affiliated with the Alexandrian Church. In addition to these efforts, Haile Selassie changed the Ethiopian church-state relationship by introducing taxation of church lands, and by restricting the legal privileges of the clergy, who had formerly been tried in their own courts for civil offenses.

During the celebrations of his Silver Jubilee in November 1955, Haile Selassie introduced a revised constitution, whereby he retained effective power, while extending political participation to the people by allowing the lower house of parliament to become an elected body. Party politics were not provided for. Modern educational methods were more widely spread throughout the Empire, and the country embarked on a development scheme and plans for modernization, tempered by Ethiopian traditions, and within the framework of the ancient monarchical structure of the state. Haile Selassie compromised when practical with the traditionalists in the nobility and church. He also tried to improve relations between the state and ethnic groups, and granted autonomy to Afar lands that were difficult to control. Still, his reforms to end feudalism were slow and weakened by the compromises he made with the entrenched aristocracy. The Revised Constitution of 1955 has been criticized for reasserting "the indisputable power of the monarch" and maintaining the relative powerlessness of the peasants.

On 13 December 1960, while Haile Selassie was on a state visit to Brazil, his Imperial Guard forces staged an unsuccessful coup, briefly proclaiming Haile Selassie's eldest son Asfa Wossen as emperor. The coup d'état was crushed by the regular army and police forces. The coup attempt lacked broad popular support, was denounced by the Ethiopian Orthodox Church, and was unpopular with the army, air force and police. Nonetheless, the effort to depose the emperor had support among students and the educated classes. The coup attempt has been characterized as a pivotal moment in Ethiopian history, the point at which Ethiopians "for the first time questioned the power of the king to rule without the people's consent". Student populations began to empathize with the peasantry and poor, and to advocate on their behalf. The coup spurred Haile Selassie to accelerate reform, which was manifested in the form of land grants to military and police officials.

The emperor continued to be a staunch ally of the West, while pursuing a firm policy of decolonization in Africa, which was still largely under European colonial rule. The United Nations conducted a lengthy inquiry regarding the status of Eritrea, with the superpowers each vying for a stake in the state's future. Britain, the administrator at the time, suggested the partition of Eritrea between Sudan and Ethiopia, separating Christians and Muslims. A UN plebiscite voted 46 to 10 to have Eritrea be federated with Ethiopia, which was later stipulated on 2 December 1950 in resolution 390 (V). Eritrea would have its own parliament and administration and would be represented in what had been the Ethiopian parliament and would become the federal parliament. However, Haile Selassie would have none of European attempts to draft a separate Constitution under which Eritrea would be governed, and wanted his own 1955 Constitution to apply in both Ethiopia and Eritrea. In 1961, tensions between independence-minded Eritreans and Ethiopian forces culminated in the Eritrean War of Independence. The emperor declared Eritrea the fourteenth province of Ethiopia in 1962.

In 1963, Haile Selassie presided over the formation of the Organisation of African Unity (OAU), the precursor of the continent-wide African Union (AU). The new organization would establish its headquarters in Addis Ababa. In May of that year, Haile Selassie was elected as the OAU's first official chairperson, a rotating seat. Along with Modibo Keïta of Mali, the Ethiopian leader would later help successfully negotiate the Bamako Accords, which brought an end to the border conflict between Morocco and Algeria. In 1964, Haile Selassie would initiate the concept of the United States of Africa, a proposition later taken up by Muammar Gaddafi.

Student unrest became a regular feature of Ethiopian life in the 1960s and 1970s. Marxism took root in large segments of the Ethiopian intelligentsia, particularly among those who had studied abroad and had thus been exposed to radical and left-wing sentiments that were becoming popular in other parts of the globe. Resistance by conservative elements at the Imperial Court and Parliament, and by the Ethiopian Orthodox Church, made Haile Selassie's land reform proposals difficult to implement, and also damaged the standing of the government, costing Haile Selassie much of the goodwill he had once enjoyed. This bred resentment among the peasant population. Efforts to weaken unions also hurt his image. As these issues began to pile up, Haile Selassie left much of domestic governance to his Prime Minister, Aklilu Habte Wold, and concentrated more on foreign affairs.
