Eugene Victor Debs (1855-1926) was a renowned American socialist, political activist, trade unionist, and one of the founding members of the Industrial Workers of the World (IWW). His book, 'Labor and Freedom' (1916), is not only a reflection of his ideals but also a blueprint for the class unionism that he actively promoted throughout his life. In 'Class Unionism,' Debs articulates his vision of a labor movement unshackled from the political constraints of the capitalist system, emphasizing the need for solidarity and collective action among workers. Debs' advocacy was grounded in the belief that the working class could only achieve true emancipation through organizing independently of political parties that represented the interests of the bourgeoisie. As a five-time presidential candidate for the Socialist Party of America, his campaign speeches and writings were infused with his unwavering commitment to socialism and workers' rights. Debs' literary style is characterized by his fervent and eloquent prose, which he used as a powerful tool to inspire and educate the laboring masses about the injustices they faced. His works continue to be seminal readings for those interested in labor history, socialist thought, and the progressive movement in the United States. Throughout his life, Debs remained an influential figure within the American Left, and his legacy persists through his contributions to political discourse and labor activism.
