This book explores the role of Great Britain in twentieth-century Latin America, a period dominated by the growing political and economic influence of the United States. Focusing on three broad themes—war and conflict; commercial and business rivalries; and responses to economic nationalism, revolution, and political change—the individual chapters cover a number of countries and issues from 1914 to 1970, stressing the reluctance with which Britain ceded hegemony in the region. An epilogue focuses on Anglo-American relations and concerns in Latin America in the more recent past. The chapters, all written by leading scholars on their particular subjects, are based on original research in a wide variety of archives, going beyond the standard Foreign Office and State Department sources to which most earlier scholars were confined.
