This book provides a complement to Dicey's The Law of the Constitution. These largely unpublished comparative constitutional lectures were written for different versions of a comparative constitutional book that Dicey began but did not finish prior to his death in 1922. The lectures were a pioneering venture into comparative constitutionalism and reveal an approach to legal education broader than Dicey is widely understood to have taken. Topics discussed include English, French, American, and Prussian constitutionalism; the separation of powers; representative government; and federalism. The volume begins with an editorial introduction examining the implications of these comparative lectures and Dicey's early foray into comparative constitutionalism for his general constitutional thought, and the kinds of response it has elicited.
