27 February 1989 saw a popular revolt, which was to escalate dramatically, break out in Venezuela. Both Caracas and most of the main and secondary cities of the country were the scene of barricades, road closures, the stoning of shops, shooting and widespread looting. This article describes the events occurring during the Caracazo or Sacudón, as the episode is known, in order to show the key role played by the weakness of a set of social and political institutions in the violent forms of collective action that prevailed. This data, on a comparative basis, may enrich our understanding of other similar uprisings in the region and worldwide.
