BOULOGNE, CONFERENCE OF (June 21-22, 1920), a meeting of the Supreme Council of the Allies, in which Japan, Greece and Belgium participated, as well as the principal European Allied Powers. Like the Conference of Hythe on May 15-17 (see HYTHE, CONFERENCE OF), it was preparatory to the Conference of Spa (see SPA, CONFERENCE OF). The question of allocating among the Allies the prospective reparation payments from Ger many was taken up, and a counter proposal (the so-called "Bou logne agreement") was prepared, in view of the expected German offer of a lump sum, should that offer prove inadequate.
