Text in German / The Study “The Growth of Pentecostal Churches in the USSR during the 20th Century” is a contribution to the research in the field of church development. The objective of this research is to investigate which missiological factors led the people in the Soviet Union to join the pentecostal churches. It should be noted that there is a wide gap in the area of international studies regarding the pentecostal movement in general.1 This can also be applied to the pentecostal movement in the USSR. So far, academic research has hardly given this area the necessary attention. For this reason the present dissertation tries to close this gap. Since this research not just follows a scientific-theoretical interest, the result should also be of use for future church development in Germany. The present historical and practical theological portrayal of the Russian pentecostal movement is based on extensive literary research. It should be given a wide as possible and yet critical review of the Russian, German and English literature. This study aims to open the difficult to access Russian literature to the German public. Moreover, the available literature is analyzed under a historical missiological aspect and practical theological conclusions are drawn from that / Practical theology / M.Th. (Practical theology)
