Decree of King Recceswinth [Visigothic Kingdom; Present-day Spain, France] [Unconfirmed]
Commentary from other sources:
1) Recceswinth forced Judaizing Christians (converted Jews who still kept Jewish traditions) to swear loyalty to the Church or die. They were forced to spend Jewish and Christian holy days with the clergy, but were not forced to eat pork.
