In the work, the author presents the characteristics of the historiography of the interwar period concerning the history of the police. The presented global and Polish trends make it possible to understand the meaning of the content of scientific and popularizing publications. Interest in the past of the police, which developed in the interwar period, focused on the 19th century, but also on the modern era (16th-18th centuries). The author's attention was drawn to two titles published in the period in question: W. Strzelecki's Safety in the Territories of Poland. From the castle farmer to the navy blue army and W. Kawka, the Police in a historical and contemporary perspective. These cross-sectional works based on scientific literature and sources representively reflect the knowledge of the police at the time. They explain its origins, present its competences and sometimes raise social problems that constituted the area of activity of the discussed institution.
