This article analyzes some cases of husband´s murderess by “neogranadinas” wives in the Viceroyalty of Nueva Granada, between 1780 and 1830. It is about trials raised upon second instance appeals, in which wives declarated that the have committed the crime in self defense and also because they were tired of the systematic physical mistreatment they were given by their husbands. The text arguments that in Nueva Granada the Virgin Mary ideal of femininity was not accomplished in those social groups where wives labored or enjoyed some sort of economic independence from their husbands. This fact implied a change in how domestic power relationships were shaped, and that impelled women not to be tolerant with punishment.
