cacerolazo

thumb|right|Casserole protest in Montreal, Quebec, Canada, on May 24, 2012 In Spanish, a cacerolazo ( or ) or cacerolada (); also in Catalan a cassolada ( or ) is a form of popular protest which consists of a group of people making noise by banging pots, pans, and other utensils in order to call for attention.

The first documented protests of this style occurred in France in the 1830s, at the beginning of the July Monarchy, by opponents of the regime of Louis Philippe I of France. According to the historian Emmanuel Fureix, the protesters took from the tradition of the charivari the use of noise to express disapproval, and beat saucepans to make noise against government politicians. This way of showing discontent became popular in 1832, taking place mainly at night and sometimes with the participation of thousands of people.
