The purpose of this study is to find out how the Swedish urban development occurred at local stages in the early 20th century. Previous studies have explained how urban transformations in Sweden took place on a general basis. Therefore, this study will have a more local focus and the community Katrineholm which grew up as a railway society during the latter part of the 19th century. Due to the railway, industries, and population growth, Katrineholm and its municipal committee began to fight for city rights. The issues this study is based on thus: What did the municipal community and its committee in Katrineholm do to fulfil city rights? What similarities and differences can be read from the communities of Nässjö and Nynäshamn that were in a similar position during the same period? The theory will therefore be based on urbanization and examine the potential development of urban areas and the opportunities and obstacles for Katrineholm. The material studied for the survey is protocol from Katrineholms archives and newspapers, from which a qualitative text analysis will be used as a method and glimpses off a comparative method to see if there are similarities in other regions. The result indicates that a significant criterium for obtaining city rights was to break away from their county municipality and incorporate their own city regulations.
