In June 1991, Mladić was promoted to Deputy Commander of the Priština Corps in the Socialist Autonomous Province of Kosovo at a time of high tension between Kosovo Serbs and Kosovo's majority Albanian population. That year, Mladić was given command of the 9th Corps, and led this formation against Croatian forces in Knin, the capital of the self-declared Republic of Serbian Krajina.
