The Souls of Black Folk is a 1903 work of American literature by W. E. B. Du Bois. It is a seminal work in the history of sociology and a cornerstone of African-American literature. The book contains several essays on race. To develop this work, Du Bois drew from his own experiences as an African American in American society. Outside of its notable relevance in African-American history, The Souls of Black Folk also holds an important place in social science as one of the early works in the field of sociology.In The Souls of Black Folk, Du Bois used the term "double consciousness," perhaps taken from Ralph Waldo Emerson ("The Transcendentalist" and "Fate"), applying it to the idea that black people must have two fields of vision at all times. They must be conscious of how they view themselves, as well as being conscious of how the world views them. Du Bois had transdisciplinary training and he provided a historical context for black religion and culture. His concept of "double-consciousness" and other concepts from Souls have been highly influential on other scholars in their interpretations of black culture and religion.

William Edward Burghardt Du Bois (February 23, 1868 - August 27, 1963) was an American sociologist, historian, civil rights activist, Pan-Africanist, author, writer and editor. Born in Great Barrington, Massachusetts, Du Bois grew up in a relatively tolerant and integrated community, and after completing graduate work at the University of Berlin and Harvard, where he was the first African American to earn a doctorate, he became a professor of history, sociology and economics at Atlanta University. Due to his contributions in the African-American community he was seen as a member of a Black elite that supported some aspects of eugenics for blacks. Du Bois was one of the founders of the National Association for the Advancement of Colored People (NAACP) in 1909. Before that, Du Bois had risen to national prominence as the leader of the Niagara Movement, a group of African-American activists that wanted equal rights for blacks. Racism was the main target of Du Bois's polemics, and he strongly protested against lynching, Jim Crow laws, and discrimination in education and employment. His cause included people of color everywhere, particularly Africans and Asians in colonies. He was a proponent of Pan-Africanism and helped organize several Pan-African Congresses to fight for the independence of African colonies from European powers. Du Bois was a prolific author. His collection of essays, The Souls of Black Folk, is a seminal work in African-American literature; and his 1935 magnum opus, Black Reconstruction in America, challenged the prevailing orthodoxy that blacks were responsible for the failures of the Reconstruction Era. He was an ardent peace activist and advocated nuclear disarmament. The United States' Civil Rights Act, embodying many of the reforms for which Du Bois had campaigned his entire life, was enacted a year after his death.
