The city name Adama may have been derived from the Oromo word adaamii, which means a cactus or a cactus-like tree. More specifically, adaamii means Euphorbia candelabrum, a tree of the spurge family, while hadaamii would mean Indian fig. Following World War II, Emperor Haile Selassie renamed the town after Biblical Nazareth, and this name was used for the remainder of the twentieth century. In 2000, the city officially reverted to its original Oromo language name, Adama, though "Nazareth" is still widely used. In 2000, the government moved the regional capital of Oromia from Addis Ababa to Adama, sparking considerable controversy. Critics of the move believed that the Ethiopian government wished to deemphasize Addis Ababa's location within Oromia. On the other hand, the government maintained that Addis Ababa "has been found inconvenient from the point of view of developing the language, culture and history of the Oromo people." On June 10, 2005, the Oromo Peoples' Democratic Organization, part of the ruling EPRDF coalition, officially announced plans to move the regional capital back to Addis Ababa.
