Scenarios about 'euro currency'

The euro is the official currency of the eurozone, adopted by 19 European Union member states since its introduction in 1999 and physical circulation in 2002. This monetary unification represents one of the most ambitious economic integration projects in modern history, creating a single currency area designed to facilitate trade, eliminate exchange rate uncertainties, and strengthen European political unity. In alternate history scenarios, the euro's implementation, membership composition, or very existence often serves as a critical divergence point for exploring different trajectories of European integration or fragmentation.
