Activist, journalist, and visionary Claudia Jones was one of the most important advocates of emancipation in the twentieth century. Arguing for a socialist future and the total emancipation of working people, Jones’s legacy made an enduring mark on both sides of the Atlantic. This ground-breaking biography traces Jones’s remarkable life and work, beginning with her immigration to the United States and culminating in her advocacy for the emancipation of the most oppressed. Denise Lynn reveals how Jones’s radicalism was forged through confronting American racism, and how her disillusionment led to a life committed to socialist liberation. But this activism came at a cost: Jones would be expelled from the US for being a communist. Deported to England, she took up the mantle of anti-colonial liberation movements. Despite the innumerable obstacles in her way, Jones never wavered in her commitments. In her tireless resistance to capitalism, racism, and sexism, she envisioned an equitable future devoted to peace and humanity – a vision that we all must continue to fight for today.
