"A People's History of the United States" is a book written by historian Howard Zinn. It presents an alternative perspective on American history, focusing on the experiences and struggles of marginalized groups, such as Native Americans, African Americans, and women. Zinn emphasizes the importance of grassroots movements and the voices of ordinary people in shaping the nation. The book challenges traditional narratives that often highlight the achievements of political leaders and military victories. Instead, it explores themes of social justice, inequality, and resistance, encouraging readers to consider history from the viewpoint of those who have been overlooked in mainstream accounts.
