International Socialist Bureau

In autumn 1914, shortly after the occupation of most of Belgium by German troops, the executive committee decided to move the headquarters from Brussels to the Hague, with the approval of the Belgian Labor Party.[2] The all Belgian Executive Committee also unanimously decided to expand itself by adding three Dutch members, Troelstra, Van Kol and Albarda, with Vleigen and Wibaut as alternates.[3] Camille Huysmans, a Belgian, remained Secretary. This arrangement was approved by all of the affiliated parties, except the French party which decline to vote, believing that the International should have stayed "where it was and what it was".[4]

In the early months of the war the Executive Committee resisted efforts to call a full meeting of the Bureau, feeling that it would have been impossible to get delegates from certain countries together and feeling that an unrepresentative meeting might mean the dissolution of the International altogether.[5] In January and February 1915 the BSI attempted to hold a series of separate, one-on-one meetings with representatives of the parties in belligerent nations. The French refused to send a delegation to the Hague. The British were at first willing, but opted out after Arthur Henderson became a member of the War Cabinet. The Belgians were the first to send a delegation, and the German party met with the executive twice.[6][7]

The BSI was pointedly hostile to the Zimmerwald Conference. At a speech to the congress of the Dutch party Huysmans ridiculed the Zimmerwaldians for their impatience, as well as for the unrepresentative and "amateur" nature of the conference.[8] Huysmans later reportedly made special trips to Britain and France to dissuade socialists in those countries from attending the Kienthal Conference.[9] Partly in response to Zimmerwald and Kienthal, though, the Bureau arranged for a meeting of socialists from the neutral countries. Originally scheduled for June 23, 1916 this conference finally met at the Hague on July 30-August 2, 1916.[10] Consisting of nine delegates from Argentina, the United States (Algernon Lee), the Netherlands, Denmark and Sweden, the conference passed a resolution expressing confidence in the Executive Committee and deprecating any effort to break up the official International[11]

In April 1917, after the March Revolution in Russia, Stauning of Denmark wrote to the BSI stating that if they were unable to summon a general conference of Socialist parties, it would be organized without them. Upon getting this appeal the Dutch members of the Executive Committee left for Stockholm. Huysmans soon joined them setting up the secretariat of the Bureau at the Trade Union House of the Swedish Socialist Party. On May 2 Huysmans and Engberg became the Secretariats representative in a new organization, the Dutch-Scandinavian Committee which attempted to convene a general socialist conference at Stockholm for the remainder of 1917, without success.[12]

In November 1918 Huysmans worked in concert with the committee appoint by the fourth Inter-Allied Socialist Conference for the convening of a socialist conference of the formerly belligerent nations. The final result of this was the Berne Conference of 1919.[13]
