It was one of the greatest relief efforts ever. In 1914-1915 Belgium, which had been overrun by the German army, was facing mass starvation of its citizens. What food that was available was largely confiscated by the Germans to feed its army.
In the United States, Americans got behind an effort to bring relief to the Belgians. The Commission for Relief in Belgium was organized, founded in part by Herbert Hoover. Kansans in particular responded generously; over 50,000 barrels of flour were donated by November 1914. Money was also contributed.
