Peace education prepares people to deal peacefully with conflicts of various scales. The authors want to enrich this education by paying attention to situations when international tension increases, and it is still possible to defuse it. Social movements sometimes highlight the hidden conflicts in society. They provoke the authorities to act and sometimes even force them to reveal their intentions. In this article, the authors look at the use of 'intervention' so-called militant research in the face of growing international conflicts and utilise the example of the humanitarian crisis for exiled people on the Polish-Belarusian border that has taken place since the summer of 2021. The possibility of using militant research is considered an inspiration to restore and preserve peace on the basis of the activism of 'Grupa Granica' [Border Group] in Poland. The case selection is based on the criteria adopted from the literature on militant research.
