This document discusses federalism and ethnic diversity in Ethiopia. It notes that Ethiopia has 84 ethnic groups, with the Oromo and Amhara being the largest. While Ethiopia attempted cultural homogenization in the past, it transitioned to an ethnic federal system in the 1990s, establishing regional states along ethnic lines with self-governance powers. The 1995 constitution established this federal system and enshrined principles like ethnic self-determination, equality, and equity in development.
