Provides a critical re-evaluation of US territorial expansionism and imperialism from 1783 to the present The United States has been described by many of its foreign and domestic critics as an “empire”. Providing a wide-ranging analysis of the United States as a territorial, imperial power from its foundation to the present day, this book explores the United States’ acquisition or long-term occupation of territories through a chronological perspective. It begins by exploring early continental expansion, such as the purchase of the Louisiana Territory from Napoleon Bonaparte in 1803, and traces US imperialism through to the controversial ongoing presence of US forces at Guantanamo Bay in Cuba. The book provides fresh insights into the history of US territorial expansion and imperialism, bringing together more well-known instances (such as the purchase of Alaska) with those less-frequently discussed (such as the acquisition of the Guano Islands after 1856). The volume considers key historical debates, controversies and turning points, providing a historiographically-grounded re-evaluation of US expansion from 1783 to the present day. Key Features Provides case studies of different examples of US territorial expansion/imperialism, and adds much-needed context to ongoing debates over US imperialism for students of both History and Politics Analyses many of the better known instances of US imperialism (for example, Cuba and the Philippines), while also considering often-overlooked examples such as the US Virgin Islands, American Samoa and Guam Explores American imperialism from a “territorial acquisition/long-term occupation” viewpoint which differentiates it from many other books that instead focus on informal and economic imperialism Discusses the presence of the US in key places such as Guantanamo Bay, the Panama Canal Zone and the Arctic
