Final answer:
The Edict issued by Henry IV of France in 1598 that offered limited religious toleration to the Huguenots is called the Edict of Nantes.
Step-by-step explanation:
In 1598, Henry IV of France issued the Edict of Nantes, an important document that offered limited religious toleration within the country. The edict specifically granted Huguenots, who were French Protestants influenced by the teachings of John Calvin, the liberty of conscience and the liberty of worship, bringing an end to the violent religious conflicts that had plagued France for decades, such as the Saint Bartholomew's Day Massacre. While Catholicism remained the official religion of France, the Edict of Nantes established certain rights for the Huguenots to practice their faith with some measure of security and marked a significant step towards religious tolerance in French history.
