The evolving geopolitical landscape has compelled Swedish decision-makers to re-examine their security policy and consider various options for adapting the national defence system to the current security environment. This publication represents one stage of research conducted by the author as part of the MINIATURA 8 grant awarded by the Polish National Science Centre (NCN). The main research question guiding the study was: How and why has Sweden’s defence policy evolved? A supplementary question addressed was: What has been – and what is – Sweden’s defence model? The methodology applied includes a legal-dogmatic method, along with an analysis of legal acts, strategic documents, and relevant academic literature. The article discusses, among other elements, the Swedish National Security Strategy of 2024 and the Swedish Total Defence Duty Act. Insights derived from the literature were complemented with data obtained during expert interviews and consultations conducted in Sweden in June 2025. To provide a broader analytical framework, the author reviewed theoretical approaches to national defence strategies, including the concept of Total Defence.
