The French demonstration of 15 May 1848 was an event played out, mostly, in the streets of Paris. It was intended to reverse the results of a Second-Republic election of deputies to the Constituent Assembly. It is difficult to say, with any precision, whether this phenomenon should be called a demonstration, a riot, an invasion, or an attempted coup d'état. Nonetheless, it seems to have been largely unplanned, not particularly bloody, and indisputably a failure.
