Vienna Socialist Conference of 1915

The Vienna Socialist Conference of 1915 gathered representatives from the Socialist parties of Germany, Austria and Hungary to the only meeting of the pro-war socialist parties of the Central Powers during World War I. Seen by some as a response of answer to the first conference of pro-Entente socialists that had gathered in London that February, the Vienna Conference met on April 12–13, 1915. It was attended by Friedrich Ebert, Hugo Haase, Luise Zietz, Hermann Molkenbuhr and Hermann Müller representing the Social Democratic Party of Germany; Ernő Garami and Zsigmond Kunfi for the Hungarian Social Democratic Party and an unknown number of representatives of the Social Democratic Workers Party of German Austria.
