A religious movement in the sixteenth century that began as an attempted reform of the Roman Catholic Church but resulted in the founding of Protestant churches separate from it. Some of the leaders of the Reformation were Martin Luther, John Calvin, and John Knox. The Reformation was established in England after King Henry VIII declared himself head of the Christian Church in that country.
