Can media have a lasting impact on attitudes in postwar countries? A lingering impact of media could substantially shape peace and security in postwar societies. Our quasi-experimental research design and original survey data utilize variation in the reception of an anti-government radio station in Nepal's Terai region, which was shut down after violent clashes. Our results show that individuals with access to anti-government broadcasts were less optimistic about peace, police and civic activism three years after the closure of the station. The study has implications for understanding the longer-term role of media for post-conflict attitudes and state-building.
