On 4 August 1914, the parliamentary representatives of the
Social Democratic Party of Germany (SPD) agreed among themselves to maintain
party discipline and voted
en bloc in support of a bill authorizing war credits for the Imperial government in the erupting international conflagration that would be remembered to history as
World War I. This stunning reversal of the Second International's position on capitalist war came as a shock to radical internationalist elements in the party, including Jogiches. Luxemburg's idea was soon abandoned due to lack of support from the broad circle of party leaders tapped for the effort, of whom no more than a small handful responded. These included Leo Jogiches,
Julian Marchlewski,
Franz Mehring, and
Klara Zetkin, her lawyer
Paul Levi, and second secretary of the SPD in Berlin
Wilhelm Pieck, among others. It would be several months after getting together before the first leaflet of the group would be published. Luxemburg was similarly targeted not long after, arrested later that same month and held for eight weeks. Anti-war sentiment was short-circuited by arrests of leaders and suppression of anti-war publications, but not silenced entirely, with more than 1,000 women demonstrating for peace in front of the
Reichstag on 28 May 1915 — further adding to the government's unease. Active efforts were made to locate active supporters in every locality and every large factory and the radical Luxemburg circle was in contact with individuals in more than 300 places by the middle of 1915. The
Internationale group held a conference on 1 January 1916, in the apartment of Karl Liebknecht, attended by 12 delegates. This group adopted a program drafted from prison by Rosa Luxemburg and was preparatory to a more authoritative gathering held on 19 March in Berlin. They sought to drive out pro-war political leaders, leaving a mass revolutionary party to await the forthcoming national revolution. Following the jailing for their anti-war efforts of Liebknecht in May 1916 and Luxemburg that same July, Jogiches took over as the leader of the organization's underground activity. As leader of the underground organization it was Jogiches that oversaw the publication of the official newsletter
Spartacus, launched in September 1916, which gave a new name to the faction — the
Spartakusbund, rendered into English as the
Spartacist League. While the revolutionary left chose not to pursue an immediate split, seeking instead to purge the party of its right-wing leadership, the pro-war majority of the SPD worked throughout 1916 to pursue a purge of their own, marked by the 24 May 1916, expulsion of 33 dissident SPD members of the Reichstag from the party for their formal disavowal of the war effort and the October seizure of
Vorwärts (Forward) from the SPD's pacifist wing by the pro-war party officialdom. A national conference of dissident socialists was held in Berlin on 7 January 1917, with 35 of the 157 delegates members of the
Spartacistbund. This gathering was ruled an effort to "sabotage" the SPD through factionalism and mass expulsions of leftists followed. The acrimony and expulsions within the SPD culminated with a formal split of the party. A Congress was held at
Gotha during Easter 1917 by the pacifist center and revolutionary left socialists, with the gathering launching a new organization, the
Independent Social Democratic Party of Germany (USPD). The
Spartakusbund would later become one of the primary forces in the unity congress which established the
Communist Party of Germany (KPD) at the end of 1918. ==Assassination==
