This paper deals with Samobor and the Samobor district during the Second World War. Firstly, the data of the city and the county before the war are presented using the censuses from 1931 and 1941. Then the most important events at the beginning of the war are shown. During 1941 a camp was established in Kerestinec from which a group of communists detained there would unsuccessfully try to escape. Also, the first partisan detachment in Žumberak, the Matija Gubec detachment, was formed from Zagreb volunteers and local people, which will also end tragically. Finally, in the city itself, a group of young people founded the Samobor Youth Anti-Fascist Group. They will read communist leaflets which they will then spread out around the city, write communist slogans on the houses of Ustasha officials, etc. However, the Ustashas will find and imprison them. The next chapter looks at the Samobor area from its political perspective. This chapter explains what political and propaganda role the city played during the war, which is shown in one personal example and two important events during the war, and what political and propaganda consequences they had. While the action of the partisans entering Samobor had no military significance, it had great propaganda importance. In contrast, the action of destroying the aviation school in Sveta Nedjelja had great military importance, but also even greater propaganda importance. After that, it is shown what political significance the fight in Žumberak had for the partisans because Slovenes, Croats and Serbs fought together there, which proved the party's policy of brotherhood and unity. The chapter after that shows the geographical importance of the Samobor district at the micro and macro level. The last chapter deals in detail with the war in the Samobor district from two perspectives, that of party activists and their sabotage and propaganda activities, and that of regular partisan units and their battles.
