Divided by blood: Race and religion in early-modern Iberia

This article argues that the mass religious conversions that took place in early-modern Iberia from the end of the fourteenth century had enormous consequences, one of which was the increasing racialisation of religion. Jewish and Muslim minorities were forced to receive baptism, and although in principle the Church made no distinction among people who had been baptised, in practice the presence of large numbers of recent converts to Catholicism called this theology into question. In the process, as I will demonstrate in this article, religion was racialised, as many people became convinced that religion (both beliefs and ritual) was biological and was transmitted by blood. To support this argument, the article will focus, as a case study, on the discussion about whether to deny baptism to the children of Moriscos (converted Muslims) in the years preceding the general expulsion from Spain of the Moriscos (1609–11).
