A People's History of American Empire is a book written by Howard Zinn. The book talks about how the United States has changed over the years and how certain people have been affected by changes in the country. The book focuses on the idea that people can make a difference in their lives and the world around them. Zinn looks at American history from the viewpoint of the people who experienced it, rather than from the perspective of those in power. For example, it looks at the experience of enslaved African Americans, Native Americans, women and other minority groups, including their struggles and successes. It also looks at US intervention in other countries and its effects on people in those societies. The book offers a different perspective on American history, one that puts people and their realities at the center.
