The Barcelona of 1842 was a keg of social conflict. Amongst the issues was the free trade policy of the regent General Espartero and the damage it was causing to the textile industry and the livelihood of workers. Another simmering issue was the tax required to be paid for bringing food into the city. A climate of permanent tension existed in the city that foreshadowed an eventual explosion of violence.
