What were the followers of Calvinism called in England?

In the Reformation, English Protestants fled to mainland Europe, where they adopted the teachings of Calvin (Calvinism). After accepting the Anglican Church, they began to return and began to spread their ideas.

In England they were called the Puritans. Like the Calvinists, the Puritans professed their exclusivity, austerity in everyday life, were tough and demanding, close-knit. They demanded the withdrawal of the remnants of Catholicism from Anglicanism: simplification of rituals, simplicity of temple decoration, introduction of sermons, etc.
