This encyclopedia offers authoritative coverage of the concepts, traditions, events, and individuals that shaped United States' foreign relations from the American Revolution to the present. Belligerents, Brinkmanship, and the Big Stick: A Historical Encyclopedia of American Diplomatic Concepts is the first comprehensive encyclopedic work to focus specifically on America's extraordinary history of political engagement with the world. With hundreds of alphabetically organized entries and a rich collection of primary sources, it offers a unique way of understanding the centrality of diplomacy and the role of foreign relations throughout U.S. history. The encyclopedia is divided into five chronological sections, each containing a brief introduction, topical entries, biographical portraits, and representative documents. It is designed to help readers gain a deeper understanding of both general ideas as well as specific policies like the Monroe Doctrine, the Open Door Policy, and Shuttle Diplomacy. By examining seminal events, important ideas, and individual contributions in the context of U.S. history, the encyclopedia reveals the underlying traditions and motivations of American foreign policy as it has evolved over time.
