The paper argues that religiosity is one of the potential determinants of political participation in Russia. A complex model of religiosity is applied, which treats individual religiosity as both belonging to religious tradition and religious behavior, while political participation includes voting, attending demonstrations, signing petitions and participating in electoral campaigns. The aim of this research is to identify whether there is a difference in political participation between religious and non-religious Russians, and between followers of different religious traditions and atheists. Secondly, it is important to explore which of the measurements of religiosity, religious tradition or religious behavior have the most powerful effect on Russians’ political participation. The data for the statistical analysis is from the European Social Survey (6th round), which includes representatives of major religious traditions in Russia.
