The author, Hubert Howe Bancroft (1832 – 1918) was an American historian and ethnologist who wrote, published and collected works concerning the western United States, Texas, California, Alaska, Mexico, Central America and British Columbia.
His history of Mexico was part of a history in 39 volumes of the entire Pacific coast region of North America, from Central America to Alaska. He employed collaborators for the preliminary work, and then revised it all, and wrote the most important chapters himself. Overall, although Bancroft considered himself the author, it is more accurate to consider him as editor and compiler.
