In 1951, the president and vice-president of the Dutch COC initiated an International Congress of European homophile groups, which resulted in the formation of the International Committee for Sexual Equality (ICSE). The ICSE brought together, among other groups, the Forbundet of 1948 (Scandinavia), the Riksförbundet för Sexuellt Likaberättigande (Sweden), Arcadie (France), Der Kreis (Swiss), and, later, ONE (U.S.A.). Historian Leila Rupp describes the ICSE as a classic example of transnational organizing; "It created a network across national borders, nurtured a transnational homophile identity, and engaged in activism designed to change both laws and minds." However, the ICSE failed to last beyond the early 1960s due to poor attendance at meetings, lack of active leaders, and failure of members to pay dues.
