Serbia still sees the territory as Autonomous Province of Kosovo and Metohija . The region currently known as `` Kosovo '' became an administrative region in 1946 , as the Autonomous Province of Kosovo and Metohija . In 1974 , the compositional `` Kosovo and Metohija '' was reduced to simple `` Kosovo '' in the name of the Socialist Autonomous Province of Kosovo , but in 1990 was renamed back to Autonomous Province of Kosovo and Metohija .
