It arose in South America (in particular Venezuela, Argentina, Chile, Colombia, Uruguay, Ecuador, Cuba, Peru, Brazil) and has been seen more recently in English- and French-speaking countries, most notably Québec, as well as in Turkey during the 2013 protests in Turkey.
What is peculiar about this type of demonstration is that people can protest from their own homes, thus achieving a high level of support and participation.
The word comes from Spanish cacerola, which means “stew pot”. The derivative suffixes -azo and -ada denote a hitting (punching or striking) action, and has been extended metaphorically to any sort of shock demonstration.
This type of manifestation started in 1971 in Chile, against the shortages of food during the administration of Salvador Allende
The last time people protested by cacerolazo was 2017 during the Catalan referendum in Catalunya. The referendum was banned by the official Spanish authorities and this action splitted catalunya in two ideologically opposite camps. Pro Independence supporters against Unionists.
