Imperialism, as defined by Dictionary of Human Geography, is "the creation and/or maintenance of an unequal economic, cultural, and territorial relationship, usually between states and often in the form of an empire, based on domination and subordination." Imperialism, as described by that work is primarily a Western undertaking that employs "expansionist, mercantilist policies".

The term as such primarily has been applied to Western political and economic dominance in the 19th and 20th centuries. Some writers, such as Edward Said, use the term more broadly to describe any system of domination and subordination organized with an imperial center and a dominated periphery.

Imperialism has been found in the histories of Japan, the Assyrian Empire, the Chinese Empire, the Roman Empire, Greece, the Byzantine Empire, the Persian Empire, and the Ottoman Empire, ancient Egypt, and India. Imperialism was a basic component to the conquests of Genghis Khan during the Mongol Empire, and other war-lords. Historically recognized Muslim empires number in the dozens. Sub-Saharan Africa has also had dozens of empires that pre-date the European colonial era, for example the Ethiopian Empire, Oyo Empire, Asante Union, Luba Empire, Lunda Empire and Mutapa Empire. The Americas during the pre-Columbian era also had large empires in Mesoamerica, such as the Aztec and the Inca.

Howard Zinn (August 24, 1922 – January 27, 2010) was an American historian, academic, author, playwright, and social activist. Before and during his tenure as a political science professor at Boston University from 1964-88 he wrote more than 20 books, which included his best-selling and influential A People's History of the United States. He wrote extensively about the civil rights and anti-war movements, as well as of the labor history of the United States. His memoir, You Can't Be Neutral on a Moving Train, was also the title of a 2004 documentary about Zinn's life and work.

Zinn was born to a Jewish immigrant family in Brooklyn. His father, Eddie Zinn, born in Austria-Hungary, emigrated to the U.S. with his brother Samuel before the outbreak of World War I. Howard's mother Jenny Zinn emigrated from the Eastern Siberian city of Irkutsk.

Both parents were factory workers with limited education when they met and married, and there were no books or magazines in the series of apartments where they raised their children. Zinn's parents introduced him to literature by sending 10 cents plus a coupon to the New York Post for each of the 20 volumes of Charles Dickens' collected works. He also studied creative writing at Thomas Jefferson High School in a special program established by poet Elias Lieberman.
