During his political career in socialist Yugoslavia, Hoxha subscribed to the principles of Yugoslav policy of "brotherhood and unity", believing in the need to achieve national equality between Albanians, Serbs, and other national groups within Kosovo and Yugoslavia. In practice, given the grave cultural and economic backwardness which previous regimes had left Albanians in Kosovo, Hoxha believed that overcoming the disadvantages faced by Albanians required special affirmative measures both within Kosovo and at the federal level. Kosovo had inherited the highest illiteracy rates in all of Yugoslavia and was also its poorest region. Hoxha consistently initiated or supported policies which would address these problems, including expanding the educational opportunities of Albanians, expanding Yugoslav programs supporting industrial development in Kosovo, and policies addressing the relative inequality of Albanians in employment, who had disproportionately high unemployment rates.
