The European Democrat Union (EDU) is one of the three European wings of the International Democrat Union, along with the European People's Party (EPP) and the Alliance of European Conservatives and Reformists (AECR). Its members include Christian democratic, liberal conservative, and conservative political parties. It is only a nominal sub-entity of the IDU, since it ceased its activities in 2002.
The EDU was more active in 2002 than it was in 2003 and 2004. 
The EDU ceased it's activities in 2002 which means that it had no activities in 2003 and 2004.  That makes 2002 more active than the years that followed.
