The Cambridge History of Capitalism, a formidable compendium of thirty-four essays spread over two volumes (each well over five hundred pages in length), was first conceived by the economic historians Larry Neal and Jeffrey Williamson in 2005. At that time, the “history of capitalism” was not yet a term of art in history departments; even in graduate workshops at Harvard, the locus classicus of the later movement, “political economy” was still the preferred phrase. By the time the book was published in 2014, much had changed: Harvard now offered a program on the “study of capitalism,” Cornell was convening a summer boot camp on the “history of capitalism,” Columbia had a book series on the history of “U.S. capitalism,” the Journal of American History had assembled a roundtable on the theme, and the front page of the New York Times had taken notice. Questions that long seemed the province of other disciplines had come to the forefront in history departments.
