On the Rights of Magistrates
Beza’s anonymous book On the Rights of Magistrates (1574) argued that public officials such as noblemen and magistrates received their authority from the people, not the king. In cases where a king or queen became a tyrant, these lesser magistrates were justified in resisting the monarch with force to preserve true religion. It is important to note that these resistance treatises were more than theoretical pieces; they provided actual justification for the Huguenot war effort against the crown in the aftermath of the St. Bartholomew’s Day Massacre.
