This thesis analyses the ideology of the Radical right-wing Populist Party, Sweden Democrats. The aim of the study is to see if and how the ideology of the Sweden Democrats has changed through its years of activity, by comparing the party in three periods. The focus in the analysis is put on the party's view on the Swedish national identity and on multiculturalism. The reason for analyzing the party's view on these two concepts is due to the fact that they can be seen as corner stones in a racist ideology. An explanation of the concepts will be presented in the theory chapter, which is later used in the analysis of the party. The study shows that the ideology of the Sweden Democrats has changed very little throughout its years of activity in terms of their view on the national identity and the multicultural idea. This as a result has led to a similar amount of change in the arguments that can be seen as racist, by the party.
