1974 Ethiopian coup d'état in the context of "Solomonic dynasty"

The Ethiopian Empire, historically known as Abyssinia or simply Ethiopia, was a sovereign state that encompassed the present-day territories of Ethiopia and Eritrea. It existed from the establishment of the Solomonic dynasty by Yekuno Amlak around 1270 until the 1974 coup d'état by the Derg, which ended the reign of the final Emperor, Haile Selassie. In the late 19th century, under Emperor Menelik II, the empire expanded significantly to the south, and in 1952, Eritrea was federated under Selassie's rule. Despite being surrounded by hostile forces throughout much of its history, the empire maintained a kingdom centered on its ancient Christian heritage.

Founded in 1270 by Yekuno Amlak, who claimed to descend from the last Aksumite king and ultimately King Solomon and the Queen of Sheba, it replaced the Agaw kingdom of the Zagwe. While initially a rather small and politically unstable entity, the Empire managed to expand significantly under the crusades of Amda Seyon I (1314–1344) and Dawit I (1382–1413), temporarily becoming the dominant force in the Horn of Africa. The Ethiopian Empire would reach its peak during the long reign of Emperor Zara Yaqob (1434–1468). He consolidated the conquests of his predecessors, built numerous churches and monasteries, encouraged literature and art, centralized imperial authority by substituting regional warlords with administrative officials, and significantly expanded his hegemony over adjacent Islamic territories.

The Derg or Dergue (Amharic: ደርግ, lit. 'committee' or 'council'), officially the Provisional Military Administrative Council (PMAC), was the military junta that ruled Ethiopia, including present-day Eritrea, from 1974 to 1987, when they formally "civilianized" the administration, though remaining in power until 1991.

The Derg was established on 21 June 1974 as the Coordinating Committee of the Armed Forces, Police and Territorial Army, by junior and mid level officers of the Imperial Ethiopian Army and members of the police. The officers decided everything collectively at first, and selected Mengistu Haile Mariam to chair the proceedings. On 12 September 1974, the Derg overthrew the government of the Ethiopian Empire and Emperor Haile Selassie during nationwide mass protests, and three days later formally renamed itself the Provisional Military Administrative Council. In March 1975 the Derg abolished the monarchy and established Ethiopia as a socialist state under a military-led provisional government. The abolition of feudalism, increased literacy, nationalization, and sweeping land reform including the resettlement and villagization from the Ethiopian Highlands became priorities. Mengistu became chairman in 1977, launching the Red Terror (Qey Shibir) political repression campaign to eliminate political opponents, with tens of thousands imprisoned and executed without trial.

The Solomonic dynasty was the ruling dynasty of the Ethiopian Empire from the thirteenth to twentieth centuries. The dynasty was founded by Yekuno Amlak, who overthrew the Zagwe dynasty in 1270. His successors claimed he was descended from the legendary king Menelik I, the supposed son of the biblical King Solomon and the Queen of Sheba, in order to legitimize the dynasty's assumption of power. Although this claimed ancestry gave the dynasty its name, there is no credible evidence that the dynasty was descended from Solomon or the Davidic line. The Solomonic dynasty remained in power until 1974, when its last emperor Haile Selassie was overthrown by a coup d'état.

Stuart Christopher Munro-Hay (21 April 1947 – 14 October 2004) was a British archaeologist, numismatist and Ethiopianist. He studied the culture and history of ancient Ethiopia, the Horn of Africa region and South Arabia, particularly their history of coins.

Born in Northern Ireland, he was initially called Stuart Christopher H. McIlwrath, but took his mother's maiden name after his parents separated. Munro-Hay studied Egyptology at the University of Liverpool from 1970 to 1974. As a student and collaborator of Neville Chittick, he worked on the 1973-74 excavation project of the British Institute in Eastern Africa (BIEA) in Aksum, the capital of the late-antique Aksumite Empire. The excavations had to be cancelled due to the Derg's coup d'état in 1974, but Munro-Hay continued to dedicate his work to researching the history of Aksum, and in particular compiled a large collection of Aksumite coins. He completed his doctorate in 1978 at the London School of Oriental and African Studies (SOAS), supervised by the then BIEA chairman Laurence Kirwan, his thesis was titled A Reappraisal of the History and Development of the Aksumite State from Numismatic and Archaeological Evidence.

The Ethiopian Revolution (Amharic: የኢትዮጵያ አብዮት) was a period of civil, police and military upheaval in Ethiopia to protest against the weakened Haile Selassie government. It is generally thought to have begun on 12 January 1974 when Ethiopian soldiers began a rebellion in Negele Borana, with the protests continuing into February 1974. People from different occupations, starting from junior army officers, students and teachers, and taxi drivers, joined a strike to demand human rights, social change, agrarian reforms, price controls, free schooling, and releasing political prisoners, and labor unions demanded a fixation of wages in accordance with price indexes, as well as pensions for workers, etc.

In June 1974, a group of army officers established the Coordinating Committee of the Armed Forces, later branding itself as the Derg, which struggled to topple Haile Selassie's cabinet under Prime Minister Endelkachew Makonnen. By September of that year, the Derg began detaining Endalkachew's closest advisors, dissolved the Crown Council and Imperial Court and disbanded the emperor's military staff. The Ethiopian Revolution ended with the 12 September coup d'état against Haile Selassie by the Coordinating Committee.

Amha Selassie (Ge'ez: አምሃ ሥላሴ, romanized: Āmiha Śəllase, lit. 'Salute of the Trinity'; born Asfaw Wossen Tafari; 27 July 1916 – 17 January 1997) was Emperor-in-exile of Ethiopia. As son of Haile Selassie, he was Crown Prince and was proclaimed monarch three times. He was first proclaimed Emperor during an unsuccessful coup attempt against his father in December 1960, during which he alleged that he was detained and compelled to accept the title. After his father was deposed in a later coup, he was proclaimed King (not Emperor) in absentia by the Derg on 12 September 1974 in an act which he never accepted as legitimate and that ended in the abolition of the Ethiopian monarchy on 21 March 1975. He was again proclaimed Emperor in exile on 8 April 1989. This time he sanctioned the proclamation and accepted its legitimacy. After his accession, his full reign name was His Imperial Majesty Emperor Amha Selassie I, Elect of God, Conquering Lion of the Tribe of Judah and King of Kings of Ethiopia.
