The Fire Next Time is a book written by James Baldwin, a renowned African American writer and social critic. Published in 1963, the book is a collection of two essays that discuss the role of race in American history and the social changes occurring at the time.

The first essay, "My Dungeon Shook: Letter to My Nephew on the One Hundredth Anniversary of the Emancipation," is a letter to Baldwin's 14-year-old nephew, discussing the role of race in American history and the future challenges he may face as a black man in the United States.

The second essay, "Down at the Cross: Letter from a Region in My Mind," discusses the relationship between race and religion, focusing on Baldwin's experiences with the Christian church as a youth and his later exploration of Islam.

The book was written during the civil rights movement, a time of significant social and political change in the United States. Baldwin's powerful and eloquent exploration of the black experience in America expressed the growing anger and frustration that many African Americans felt towards the racial injustices prevalent in American society during the 1960s.
