If the South Had Won the War

If the South Had Won the Civil War is a 1961 alternate history book by MacKinlay Kantor, a writer who also wrote several novels about the American Civil War.[1] It was originally published in the November 22, 1960, issue of Look magazine. It generated such a response that it was published in 1961 as a book.
The book is written in the manner of a history text published in the alternate reality of 1961 and describing the developments of the past century, in which the Confederate States of America had existed as a separate nation-state. It includes numerous footnotes and quotations from various (fictional) historical writings.
The book had a considerable influence on the development of the subgenre of American Civil War alternate histories, one of the two most frequent subjects of American alternate history. Later writers of such books, such as Harry Turtledove, explicitly stated Kantor's influence on their own work.
