The first decade folloming World War II saw a number of administrative-territorial reforms being carried out. One of such changes was the establishment of towns as a form of the local administrative-territorial units. Their development was rather complex, since a number of administrative-territorial units, all of them representing towns, were enacted within these ten years: from the spring of 1945 to Maj 1949 Ljubljana as the capital of the Republic, county town and a town exempt from authority; Celje and Maribor as district towns or towns exempt from districts. The same status was between 1950 and 1952 acquired by the cities of Jesenice, Kranj and Bled. From April 1952 to June 1955 the cities were as follows: (Ljubljana, Celje and Maribor), town municipalities with speciftc rights within the structure of districts (at ftrst there were 13 of them, but the number rose to 14, when Celje joined them in March 1954) and town municipalities within the structure of districts (31) whose status was the same as that of municipalities.
