Historical sources of British Euroscepticism trace back to the country's relationship with the European Union (EU) since its inception. Rooted in a deep-seated sense of sovereignty and national identity, Euroscepticism gained momentum in the 1990s and early 2000s, particularly within the Conservative Party and parts of the British public. Key historical factors contributing to Euroscepticism include Britain's late entry into the European Economic Community (EEC) in 1973, with concerns over diminished national control and economic repercussions. The Maastricht Treaty of 1992, which led to the establishment of the EU and the Eurozone, further fueled suspicions over potential loss of autonomy and unelected European bureaucracy. Issues like the Common Agricultural Policy (CAP) and Common Fisheries Policy (CFP) stoked discontent among British farmers and fishermen, perceiving EU regulations as detrimental to their interests. Additionally, public debates surrounding immigration, border control, and the free movement of people triggered Eurosceptic sentiments, especially during periods of increased migration from EU member states. Notably, the eurozone's economic struggles, exemplified during the 2008 financial crisis, reinforced doubts about Britain's decision not to adopt the euro currency. Overall, these historical sources of Euroscepticism in the early 2000s contributed to a growing skepticism towards the EU's role in Britain's governance and fostered an ongoing debate about the country's relationship with the European project.
