Through successive enlargements, the Union has grown from
the six founding states — Belgium, France, West Germany, Italy,
Luxembourg, and the Netherlands — to the current 28. Countries
accede to the union by becoming party to the founding treaties,
thereby subjecting themselves to the privileges and obligations
of EU membership.
