EU policy responses to the migration crisis caused by the Russian war against Ukraine challenge existing explanations of EU migration policy, which have typically leaned on economic rationales. This study leans on public attitudes to shed light on Poland's opposition to migration co‐operation across three recent European migration crises: Syria (2015), Belarus (2021) and Ukraine (2022). Throughout these crises, Poland has become a significant migration border country and one of the top refugee‐receiving countries. We build an analytical framework for exploring how the Polish government instrumentalised ‘parochial attitudes’ that prioritise sovereignty, locality and the in‐group and exclude out‐groups, and we analyse Poland's (op)position to EU co‐operation on migration through this lens. Using survey data, policy documents, 83 media articles and 10 interviews with policy‐makers and experts, we demonstrate that Poland's position on EU solidarity measures has remained static despite the dynamic, evolving circumstances and aligned with parochial attitudes amongst the public.
