John Quincy Adams: Policymaker for the Union focuses on Adams's ideals of the centrality of the union to American happiness, the necessity of federal action to protect the union, and the indivisibil-ity of foreign and domestic concerns. This book's examination of these three points casts new light on the logic behind many of Adams's accomplishments and also exposes the sources of some of his failures. This is the first study to examine how Adams's views ultimately led to his failure as a policymaker. This book is ideal for courses in diplomatic history, American history, and American political history.
