Since Van Loon's death in 1944, The Story of Mankind has been added to extensively by his son, Gerrit van Loon. Van Loon explains in the book how he selected what and what not to include by subjecting all materials to the question: Did the person or event in question perform an act without which the entire history of civilization would have been different? After its first edition, Van Loon had another edition published later in the 1920s which included an extra essay, called "After Seven Years" about the effects of World War I.

Written for his children (Hansje and Willem), The Story of Mankind tells in brief chapters the history of western civilization beginning with primitive man, covering the development of writing, art, and architecture, the rise of major religions, and the formation of the modern nation-state. In 1922, it was the first book to be awarded the Newbery Medal for an outstanding contribution to children's literature. It stars Ronald Colman and an all-star cast, featuring, among others, the Marx Brothers.The Story of Mankind was written and illustrated by Dutch-American journalist, professor, and author Hendrik Willem van Loon and published in 1921.
