The Oromo Liberation Front was founded to oppose perceived colonisation by which African country?

The Oromo Liberation Front (OLF) is an organisation that was established in 1973 by Oromo nationalists to promote self-determination for the Oromo people against perceived Ethiopian (when it was known as Abyssinia) colonial rule. The proponents of the movement hold that Amhara hegemony has been oppressing and suppressing the Oromo people and their culture. The movement is the culmination of over 70 years of uncoordinated resistance by Oromos against this condition. It has been outlawed and labelled a terrorist organisation by the Ethiopian government.

The OLF has offices in Asmara (a military base), Washington, D.C. and Berlin from where it operates Amharic and Oromo-language radio stations.

In 1967, the imperial regime of Haile Selassie I outlawed the 'Mecha and Tuluma Self-Help Association' (MTSHA) and later instigated a wave of mass arrests and killings of its members and leaders. Prominent military officer and leader of the association, Colonel General Tadesse Birru, was also arrested.

This reaction by the regime had been caused by the popularity of the organization among the Oromos people. In 1973, the political situation of the country had changed and the Ethiopian military had ousted the imperial regime and taken control.

In August 2018, a peace agreement was forged between the Ethiopian government and the OLF, ending the 45-year Oromo conflict.
