Why did puritans start a colony separate from the pilgrims

The Pilgrims and Puritans came to America to practice religious freedom. In the 1500s England broke away from the Roman Catholic Church and created a new church called the Church of England. Everyone in England had to belong to the church. ... The Pilgrims decided to settle in this area and called it Plymouth.
