Today in Labor History May 3, 1968: The first battles of the May Upheaval began in the Latin Quarter of Paris. The police arrested 500 students meeting at the University of Sorbonne to protest repression at Nanterre. Revolt broke out along the route taken by police vans, with thousands fighting against the police. Throughout the month of May and part of June, workers and students occupied schools, factories and offices. By mid-May, 10 million workers were on strike.
