9 May every year: Celebrating the creation of the European Union.
Europe Day commemorates 9 May 1950, when the then French Foreign Minister Robert Schuman presented his proposal on the creation of an organised Europe, to help maintain peaceful relations between European countries. This proposal, known as the 'Schuman declaration', is considered to be the act that created what is now the European Union.
Each year's Europe Day has a different theme. Check on the European Commission website to find out more about the theme for 2015. You could use Europe Day at school to explore the theme in more depth, or find out more about the European Union.
