Interesting Background
The euro’s origins trace back to post-WWII European unity dreams, formalized by the 1957 Treaty of Rome and the 1992 Maastricht Treaty. Its banknotes, designed by Robert Kalina, symbolize bridges and gateways.
The euro was not born of economic theory alone. Its roots trace back to the ashes of World War II, when European leaders dreamed of peace through shared prosperity. The idea gained traction with the 1957 Treaty of Rome and matured in the 1992 Maastricht Treaty, which set strict criteria on inflation, debt, and budget deficits. The currency’s name was chosen in 1995, and its banknotes were designed by Austrian artist Robert Kalina, featuring bridges and gateways symbolizing unity and openness. The first physical euro coins from San Marino and the Vatican—minted in limited editions—now sell for up to €10 apiece among collectors.
Honestly, this is one of the most fascinating currency stories out there. The euro’s stability has made it a global reserve currency, second only to the U.S. dollar. According to the European Central Bank, about 20% of global foreign exchange reserves were held in euros as of 2025, a figure unchanged since 2020 European Central Bank.
