The dataset consists of 301 semi-structured interviews with Russian citizens conducted from February 2022 until December 2022. The topics of the interviews are: attitudes toward Russia's invasion of Ukraine, emotions regarding Russia's invasion of Ukraine, media consumption, communication with others about Russia's invasion of Ukraine, change of the attitudes toward the war over time, visions of the future of the conflict, basic biographical information and political experiences of the informants. The search for informants was organized through the “snowball” method with the help of social networks on the Internet and the personal connections of researchers outside of academic and liberal milieus. The dataset mainly covers the European part of Russia and big rather than small Russian cities. The informants have various social and economic backgrounds, however, people with higher education are overrepresented in the dataset.
