In the heat of an economic and political crisis, people in Argentina took to the streets on December 19th 2001, shouting 'All of them out!', banging pots and pans, protesting by the thousand against every politician, economist and journalist in the country. These events opened a period of intense social unrest and political creativity that led to the collapse of government after government. Neighbourhoods organised into hundreds of popular assemblies, the unemployed workers movement acquired a new level of visibility and workers took over factories and businesses.
