Originally published in 1940, this book was written by the British legal academic and educationalist Sir William Ivor Jennings (1903–65). The text presents a discussion regarding the possible nature of a federal Western Europe and the means through which this outcome might be achieved, putting forward the view that 'The desirability of replacing international anarchy by international government is so generally recognised in Great Britain that it needs no demonstration'. Legal, constitutional and economic elements of a possible European government are discussed, along with foreign policy and defence. This book will be of value to anyone with an interest in European history and the development of the European Union.
