This masters thesis explores the changes in the daily lives of Jews in Belgrade and Zemun between 1878 and 1912. It begins with an historical overview of the Jewish community in Belgrade during Ottoman rule, giving an introduction to the Belgrade Jewish neighborhood of Mahala Jalija. Subsequently, the legal and social status of the Jewish communities in Belgrade and Zemun, which in turn created a framework for the organization and structure of the Jewish communities (like the constitution of the Sephardic communities), and the economic situation of the Jewish society, will be analyzed. This work also deals with the cultural, social and professional life of the Jews, therefore special attention will be paid to cultural societies, synagogues, cemeteries and areas of employment. One of the aims of this work is to preserve the memory of these prominent figures of Jewish life. Thus, important Jewish persons from both cities, such as Geca Kon, the Koen family, Hajim Davičo, the Amar family, Avram Ozerović, Regina Jeliševa or Aladar Polak will be reviewed. Another focus of this work is the changes in the daily lives of Jewish women. Jewish womens societies from Belgrade will be discussed and references to their level of emancipation will be proven. Hereafter the Jewish educational system will be discussed and Jewish schools in Belgrade and Zemun reviewed. The Zemun Jewish school will be paid special attention. At the end, the national classification of the Jewish communities and Zionist movement in Zemun and Belgrade will be processed. This work compares especially the cultural, political and social life of the two Jewish communities, whilst simultaneously studying the ambivalent relationship of the Jews with the Serb society, questioning the myth of the everlasting deep friendship between Jews and Serbs.
