A comprehensive, richly detailed, and elegantly written account of the republic between the War of 1812 and the American victory in Mexico a generation later...a masterpiece. The Atlantic Howe has written a stunning synthesis of work in economic, political, demographic, social and cultural history, and he gives a fascinating, richly detailed portrait of the U.S. as its very boundaries so dramatically and often violently shifted...it is a rare thing to encounter a book so magisterial and judicious and also so compelling; it is a great achievement and deserves many readers beyond the academy.
