Who wrote "A People's History of the United States"?

The correct answer is Howard Zinn. He is the author of "A People's History of the United States," which was published in 1980. This book presents American history from the perspective of marginalized and oppressed groups, challenging traditional narratives that often focus on elites and major political events. Zinn's work emphasizes the experiences of common people and highlights issues such as class struggle, racism, and labor rights, providing a more grassroots view of historical events. This approach has made the book a pivotal and influential text in both educational settings and social movements, encouraging readers to consider history through a lens that often goes unnoticed in mainstream accounts.

The other individuals listed, such as Arthur Schlesinger Jr. and Upton Sinclair, while significant historical figures and authors, did not write this particular work. Schlesinger is known for his works on American history and political commentary and Sinclair is best known for his novel "The Jungle," which criticized industrial capitalism. "Nineteen Eighty-Four," on the other hand, is a dystopian novel written by George Orwell and is unrelated to the historical discussions intended in Zinn's work.
