International Old Catholic contacts between young people were established soon after the foundation of the Union of Utrecht. However, the two World Wars made it difficult to maintain these contacts, and it was not until the early 1980s that an association was set up to foster relations between young people in the Old Catholic Churches. The International Old Catholic Youth association has a managing committee and a general assembly. Its members are the youth associations of Germany, the Netherlands, Switzerland, Austria, Poland and the Czech Republic.
At present, however, the youth associations only work together through the contact persons in the different countries. At times, there have been international summer and winter holiday camps. The young people meet mainly during the Youth Congresses, which take place parallel to the International Old Catholic Congresses.
