This article attempts to prove that the sense of English identity and English nationalism were two key factors in the UKâs decision to withdraw from the European Union and indicates the evolution of the Eurosceptic attitude in the UK to the point at which UKâs citizens were divided by the referendum in 2016 into two categories: Brexiters and Remainers. In adopting a socio-cultural perspective, it provides an empirical analysis of a survey made in 2012 by the Future of England regarding English nationalism and the way such attitudes as Euroscepticism, Britishness or Englishness affected the results of the 2016 EU referendum in the UK. It starts with the main features of nationalism in UKâs component countries (Black 2021) and ends with a few personal conclusions regarding the way the Eurosceptic attitude was used by the Brexitersâ campaign in order to achieve its purpose.
