The Corpus de Sang (Catalan pronunciation: [ˈkɔɾpuz ðə ˈsaŋ], "Corpus of Blood") was a riot which took place in Sant Andreu de Palomar and later in Barcelona on 7–10 June 1640, during Corpus Christi, which marked a turning point in the development of the Reapers' War.
The riot was between a group of harvesters and some local "andreuencs", during which one harvester was badly hurt.
