Henry Steele Commager was an American historian who helped define Modern liberalism in the United States for two generations through his 40 books and 700 essays and reviews.
There are two volumes, both very large but worth the read. Both volumes have been reprinted over and over again and has stood the test of time. It was originally published in the 1930s. It is textbook-like, however, it contains SO MUCH information. It is a great resource for historians, history buffs, and people who are interested in American history. It is a highly regarded book by many and it contains almost anything you wanted to know. The first volume deals with the early years of the republic up to about 1865. The second volume starts from 1865 to what we now know as modern america. There are pictures, graphs, a bibliography and appendixes. Like I said before, this is a great resource and a really nice addition to any collection. I really enjoyed reading it.
This was one of Dad's books from Grinnell College which he attended on the GI Bill after WWII. I read it as preparation for the U.S. History requirement at Maine Twp. H.S. South in Park Ridge, Illinois.
