After providing a brief explanation of the Union&#8217;s accession process, based on the 2021 revised methodology, the article presents a quantitative analysis using the European Commission&#8217;s progress reports. This analysis compares two periods: the post-invasion period (2022-24) and the pre-invasion period (2018-21), which includes the pre-pandemic years. The qualitative dimension explores the specific developments of each country during these periods. The study concludes by considering the prospects and challenges for each candidate country, taking into account the impact of the Russia-Ukraine War on the progress of their accession processes.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo Este artigo propõe uma análise mista do impacto da invasão russa da Ucrânia, iniciada em fevereiro de 2022, no alargamento da União Europeia e nos processos individuais de adesão de cada país candidato, potencial candidato e requerente. Após breve explicação do processo político-jurídico de adesão à União, com a metodologia revista em 2021, apresenta-se uma análise quantitativa baseada nos relatórios de progresso da Comissão Europeia, comparando dois períodos: pós-invasão (2022-2024) e um período anterior (2018-2021), incluindo anos pré-pandémicos. A vertente qualitativa explora os desenvolvimentos específicos de cada país nesses períodos. O estudo conclui com as perspetivas e desafios para cada candidato, considerando o impacto da Guerra Russo-Ucraniana no avanço dos seus processos de adesão.]]></p></abstract>
