Title:
Huguenot

Context:
The Catholic Church in France and many of its members opposed the Huguenots. Some Huguenot preachers and congregants were attacked as they attempted to meet for worship. The height of this persecution was the St. Bartholomew's Day massacre when 5,000 to 30,000 were killed, although there were also underlying political reasons for this as well, as some of the Huguenots were nobles trying to establish separate centers of power in southern France. Retaliating against the French Catholics, the Huguenots had their own militia.

Question:
What was a non-religious reason for the massacre?
