Juana Belén Gutiérrez Chavez (later de Mendoza), from Mexico was an advocate for worker’s in Mexico, Indigenous rights, and the founder of a group that advocated for better working conditions for women. She later became a teacher, translated numerous classic anarchist texts into Spanish, and contributed prolifically to revolutionary publications, and more mainstream ones on working class issues.
In 1907, she founded Las Hijas de Anáhuac, an anarchist-feminist group which agitated for strikes for better working conditions for women. She enthusiastically took part in the revolution which began in 1911, and was imprisoned for three years. Upon her release she set up a military unit in the army of Emiliano Zapata, who made her a colonel. She kept up her political activity advocating for rights for women, workers and Indigenous peoples until her death in 1942. (Source: Instagram- Working Class History)
