Its a long story.. but its just bcz the country is devided by ethnic groups and some groups ruled for a long time ,some were not given enough attention ... and people are still hunged up on the past they fight over some thing that happened 100 years ago by saying this ethnic group killed this group stuff like that. Our new PM wanted to unite the country by forgeting and forgiving abt the past and starting a new political party that is clear of any ethnical background a party for the whole Ethiopia but some ppl dont like the idea simply because they want their ethnic group to be superior
