Between 1917 and 1919, Rīga experienced significant violent upheavals, bringing violence into the everyday lives of much of the population. This tumult was part of a broader process spanning Eastern and Central Europe from 1917 to 1923, as major land empires collapsed, accompanied by wars, insurgencies, and revolts. While the processes of 1917-1923 have received considerable attention in historiography, the legacies of this violence remain only partly explored. The research project aims to delve into these legacies, focusing on political street violence in interwar Rīga during the parliamentary period (1920-1934). Street confrontations will be used as a prism to explore the relationship between past experiences of violence and political radicalisation. Key research questions include understanding how past experiences of violence in 1917-1919 shaped radicalisation in Rīga’s diverse society under democratic rule, exploring factors sustaining street fighting, and examining continuities/discontinuities with conflicts of 1917-1919 and street confrontations of 1920-1934. The approach involves cataloging instances of political street violence, identifying actors, detailing social portraits of street fighters and their trajectories, and analysing discourses within street-fighting groups. This comprehensive investigation not only contributes to historical knowledge but also offers insights into contemporary discussions on the relations between violence and radicalisation.
