This volume examines the multifaceted consequences of Russia’s 2022 invasion of Ukraine, with a focus on Hungary and Poland. It offers an interdisciplinary exploration of legal, social, and political responses to the war, highlighting the refugee crisis, resource challenges, and security implications. Divided into two parts, the book first addresses the unprecedented displacement caused by the war, analysing refugee protection frameworks, humanitarian assistance, and legal solutions in Hungary and Poland, alongside the specific needs of vulnerable groups. The second part expands the scope to consider broader impacts, including technological and cultural dimensions, energy security, and public discourse in the region. By bringing together contributions from Polish and Hungarian scholars, this volume provides a comprehensive and nuanced perspective on the far-reaching effects of the war, offering critical insights into the legal and socio-political transformations shaping Central and Eastern Europe.
