The Tigrayan issue in Ethiopia has deep historical roots.The nobles'struggle for the central power,the maintenance of local autonomy,and the increasing survival pressure of peasants led to the"Woyane Revolt"in the 1940s.Despite the emergence of separatist claims in the revolt,more people were concerned about the issue of taxation,and expected the government to adjust its policies.After the revolt was quelled,the central government further marginalized the Tigrayan people,and the local living conditions were not improved,thus resulting in the Tigrayan nationalist movement led by the intellectuals in the 1970s.In the course of the conflict,the TPLF claimed independence and statehood,but as the balance of power changed,it sought to seize the central power and transform the state of Ethiopia into an ethnic federal system.After coming to power in 1991,the TPLF sought to exert political and economic control over other ethnic groups and expand the privileges of the Tigrayan people at the national level.With the eventual loss of central power to the Ethiopian Prosperity Party(EPP)that restarted the centralization reform,the Tigrayan people once again proposed separation and ethnic autonomy,leading to the outbreak of a civil war in 2020.The Tigrayan people wavered between"transforming Ethiopia according to their own will"and"separation to build an independent state",but they have never got ready to separate and build a state of their own.The Tigrayans opposed the encroachment of other ethnic groups on their own autonomy,but they repeatedly violated the rights of other ethnic groups when they were in power,trying to establish a network of Tigrayan privileges that would extend throughout the country and accommodate the loyalists of other ethnic groups.The Tigrayans embrace the ideas of unity,autonomy,separation and so on,but focus on each of them in different periods.Among them,unity is intended for the expansion of the Tigrayan people's autonomy and privileges,while separation is the last resort of their assertion of ethnic rights.
