The first woman to lead a labor movement was Mary Harris "Mother" Jones. She played a crucial role in advocating for workers’ rights and improving conditions for laborers during the late 19th and early 20th centuries. Her tireless efforts galvanized the working class, and she co-founded the Industrial Workers of the World (IWW), promoting solidarity among workers. Jones's compelling speeches and mobilization tactics made her a prominent figure in the struggle for labor reform in the United States, leaving an enduring legacy in the history of workers' rights movements.
