In times of new geopolitical challenges, many states have revived the concept of total defence, in which all citizens contribute to national defence efforts. How authorities communicate the need of this new defence strategy and when such crisis communication leads to an increased defence willingness is an important research question. We hypothesise that individuals who feel a sense of empowerment or an increased risk of war when exposed to crisis communication are more willing to engage in the defence. To evaluate our hypotheses, we collected representative survey data from 2,068 Swedish respondents, at the same time as the Swedish Civil Contingencies Agency was distributing a new brochure on expectations on and advice for citizens in case of war. By analysing the responses of individuals who had read or not read the brochure, we gauge the impact of the crisis communication on defence willingness. The results show that individuals experiencing a higher sense of empowerment and perceiving a higher risk of war when having read the booklet were more willing to engage in total defence activities. This has important implications for our understanding of how specific types of crisis communication influence commitment and defence willingness in the population.
