After Germany invaded Belgium in August 1914, a British blockade to prevent supplies reaching Germany also isolated the Belgian people. The Commission for Belgian Relief (CRB), chaired by future U.S. president Herbert Hoover, negotiated delivery of food and goods to civilians living there. Among the items was thread to Belgian lace makers. The CRB managed sales and deliveries of Belgian war lace to people in the Allied countries wishing to support the Belgian population.
