This book analyzes the negotiation of socio-political concepts, such as citizenship, republicanism, and representation, between “ordinary” French citizens and their representatives in parliament during the early twentieth century. By examining the letters written to French Deputies of the Chamber (députés) at a tumultuous time in French political history, the author sheds light on the role that politically unorganized citizens played in the process of democratization. Central to the investigation are the aspirations, wishes and demands of individuals acting on their own or as spokespersons for informal communities. The way that they formulated personal requests in their letters to députés reveals their expectations of political representatives, the regime, and their own place in society. By taking a closer look at the epistolary relations between voters and non voters on the one hand and their deputies on the other during a time of rapidly succeeding governments, economic crises and changes in electoral laws, this book demonstrates how the Third Republic’s existence was co-determined by ordinary citizens’ perceptions of the regime. Helping readers to reflect on the nuances of the politicization process, this innovative book offers unique insights for those researching French political history and modern European political culture.
