The EU

With its foundations in the ashes of World War II, the European Union was initially formed to avoid further wars and remove trade barriers. It grew from a six-nation club as the ECC in 1957, to today’s 27 members that covers much of the continent and has evolved to tackle contemporary issues such as mass migration, a global pandemic and the war in Ukraine.

In recent years, it survived a wave of Euroscepticism that led to Britain leaving (Brexit), but other member states have looked to reform from within, preferring to stay part of the larger bloc during uncertain times.
