Forty years ago, on October 15, 1983, a handful of young people set off from the southern French city of Marseille on a long march north to Paris. They were demanding equal rights and a stop to racist crimes blighting France at the time. By the time they reached the French capital on December 3, they were flanked by tens of thousands of demonstrators. FRANCE 24 brings you a special 50-minute documentary looking back at this historic event and its legacy.
