The European Union was formed in the years after the Second World War to secure peace and promote economic progress. It aimed to achieve that by ensuring that countries worked together. But that optimistic vision has now been shaken. There is mounting anxiety about whether the EU can hold together. Some are even saying that the EU is facing an existential crisis. That’s because the elections in May are likely to bring in another wave of populist politicians promoting nationalist agendas. The Inquiry will detail the fissures that have been exposed in recent years. One cause has been migration from countries outside the EU and the pressures caused by free movement within its borders. The severe economic downturn has threatened unity too. Kavita Puri explores whether there are moments in the European Union’s history when, had different decisions been made, the EU might have hung together better.
