 Kinderland was founded by members of The Workmen's Circle/Arbeter Ring, a leftist Jewish fraternal organization, in 1923 in Hopewell Junction, New York.Camp Kinderland, along with the rest of the left wing of the Workmen's Circle, split off in 1930 and created the International Workers Order and became the official summer camp of the Jewish section of the IWO.In 1954, the IWO was shut down and its assets liquidated by the government, which had determined that it was a Communist organization.
