The Chicago Defender, which was founded by Robert S. Abbott on May 5, 1905, once heralded itself as "The World's Greatest Weekly." The newspaper was the nation's most influential black weekly newspaper by the advent of World War I, with more than two thirds of its readership base located outside of Chicago. Abbott began his journalistic enterprise with an initial investment of 25 cents, a press run of 300 copies, and worked out of a small kitchen in his landlord's apartment.
