In early 1945, the Yugoslav partisan brigades managed to establish military control over Kosovo. The violent suppression of Albanian resistance was followed by establishment of the Yugoslav administration in Kosovo. The status of an autonomous region within Serbia and the Yugoslav Federation was given to Kosovo. Kosovo's autonomy was very limited, it only had the right to make decisions and not to promulgate any law or further. Albanians did not have the right to use their native language and national symbols, even though they made up about 70% of the population in Kosovo. Such a situation lasted until 1966 when the concept of state decentralization prevailed in Yugoslavia. In new circumstances, the Albanians became a factor of political balance in the Yugoslav federation. Taking advantage of circumstances, Albanians managed to improve their legal status, which was crown with the Constitution of 1974. This Constitution gave full rights to self-government in Kosovo and even features of statehood. Therefore, the article “Kosovo in the Constitution of 1974” aims to identify and analyse some constitutional aspects, Kosovo's relations with the republic and federation, particularly as the overthrow of Kosovo's autonomy was the prelude to the bloody wars towards the dissolution of Yugoslavia.
