The Young Communist International was the parallel international youth organization affiliated with the Communist International (Comintern). After failed efforts to form an international association of socialist youth organizations in 1889 and 1904, in May 1907 a conference in Stuttgart, Germany convened to form the International Union of Socialist Youth Organisations (the Internationale Verbindung Sozialistischer Jugendorganisationen, abbreviated IVSJO). IVSJO maintained its headquarters in Vienna and functioned as the youth section of the Second International. At its foundation the International Secretary of IVSJO was Hendrik de Man. De Man was succeeded by Robert Danneberg, who held the post from 1908 to 1915. The first Chairman of the IVSJO was the German anti-militarist radical Karl Liebknecht. Liebknecht served as an inspiration and "elder statesman" for radical youth throughout Europe.
