"My fascination with the past began one summer in California when my mother brought home a shoebox full of letters from my great-great grandfather, a drummer boy from Vermont who served in the Civil War and wrote home to his parents. Without quite realizing it, I became a historian that summer." His new book, The Cause of All Nations: An International History of the American Civil War (Basic, 2015), is a bold new interpretation of what "our Civil War" meant to the wider world.Visit the author on Facebook: https://www.facebook.com/causeofallnations
