Aman Mikael Andom (1924 – 17 November 1974) was the first post-imperial acting Head of State of Ethiopia. He was an Eritrean originally from the village of Tse'azega in Hamassien province of Eritrea. He was appointed to this position following the coup d'état that deposed Emperor Haile Selassie on 12 September 1974, and served until his death in a shootout with his former supporters. His official title was Chairman of the Provisional Military Administrative Council (better known as the Derg), and he held the position of Head of State in an acting capacity as the military regime had officially proclaimed Crown Prince Asfaw Wossen as "King-designate" (an act that would later be rescinded by the Derg, and which was never accepted by the Prince as legitimate).

As commander of the Third Division, General Aman had been beating back the encroachments of the Somali army on the eastern border with a zeal and success that he was known as the "Desert Lion." However, in 1964 the Emperor dismissed General Aman Andom when he began to attack into Somalia in violation of an order from the Emperor, and Aman afterwards served in the Ethiopian Senate in a "political exile". There is some evidence that indicates he had contacts with the officers of the junta as early as February and March 1974, but by July he was appointed chief of staff to the military junta. Three days after the junta removed the Emperor from his palace to imprisonment at the headquarters of the Fourth Division, this group appointed him their chairman and president of Ethiopia. At the same time, this group of soldiers assumed the name "Provisional Military Administrative Council", better known as the Derg.

In J. R. R. Tolkien's legendarium, Aman, also known as the Undying Lands or Blessed Realm, is the home of the Valar, and three kindreds of Elves: the Vanyar, some of the Noldor, and some of the Teleri.

Aman is a continent far to the west of Middle-earth across the great ocean Belegaer. The island of Tol Eressëa lies just off its eastern shore. At the end of the Second Age, Aman was removed from the surface of the Earth to another realm, and is no longer reachable by ordinary means of travel.

Eldamar is "Elvenhome", the "coastal region of Aman, settled by the Elves", wrote Tolkien. Eldamar was included in Valinor, which meant the "land of the Valar", but was the true Eldarin name of Aman, according to Tolkien.

The size of Eldamar is unknown, but the area between the Bay of Eldamar and the Pelóri was probably at least a few dozen miles wide; Eldamar also consisted of the shore of Taniquetil and the Calacirya pass where Tirion was built. The shore probably extended hundreds of miles to the north of the Calacirya.
