First published in 1927 and delivered as the Watson Chair Lectures to various British universities in the same year, this book sets out 'the progress of that mutual understanding between the American and British governments' which has flourished in the peaceful period lasting from the end of the War of 1812. American academic McElroy examines certain 'typical episodes' in Anglo-American relations since the Declaration of Independence and comments on their wider diplomatic significance. This book will be of value to anyone with an interest in understanding the United States and the history of the 'special relationship'.
