The book "Politics and Religion in Teschen Silesian" offers an in-depth analysis of the role of the religious factor in political elections in the Cieszyn district between 2001 and 2015. This region, which encompasses parts of Poland and the Czech Republic, is historically characterized by a diverse religious and national composition. The author, Andrzej Rudowski, examines voting behavior in ethnically homogeneous communities that are either inhabited by a majority or a significant proportion of Protestants or Catholics. By comparing six selected communities, a comprehensive picture of the interactions between religion and politics in this unique region is drawn. The book is aimed at readers interested in the complex relationships between religion and political behavior and provides valuable insights into the dynamics of elections in Cieszyn Silesia.
