Addis Ababa is located in the heart of the Oromia state and the major ecosystem services to the city provided by Oromia state. The city was abandoned by the Oromo since the late 19th century due to its conquest by Menelik.  Oromos were physically removed from the vicinity of the city during the Haile Selassie and Derg eras. Article 49(5) of the Constitution of the Federal Democratic Republic of Ethiopia states: In 2000, Oromia's capital was moved from Addis Ababa to Adama. Because this move sparked considerable controversy and protests among Oromo students, the Oromo Peoples' Democratic Organization (OPDO), part of the ruling EPRDF coalition, on 10 June 2005, officially announced plans to move the regional capital back to Addis Ababa. Due to the historical and natural connection between the city and the Oromo people, the Oromia Government has asserted its ownership of Addis Ababa. Both the current mayor of Addis Ababa, Adanech Abebe, and the former mayor, Takele Uma Banti are from the former ruling party of Oromia.
