Historian Howard Zinn's autobiographical writings were shaped by his diverse experiences, including his time as a WWII bombardier and his involvement in the civil rights movement. His working-class background instilled a sense of social justice, leading him to challenge the traditional narratives of American history. Zinn's commitment to activism and advocacy for marginalized voices motivated his efforts to promote a history seen through the lens of the oppressed. His book, "A People's History of the United States," encapsulates his belief in historical revisionism, prioritizing the perspectives of ordinary people over elite narratives.
