At the risk of oversimplifying everything to do with English conflicts over belief systems, the English Civil War in the 1600s gave rise to the Puritans but also saw the emergence of numerous other dissenting Christian groups including the Quakers. In brief, the Quakers were seen as a problem theologically and politically. They refused to swear fealty to the Crown because of religious beliefs and they also threatened to undermine the power of the clergy through their insistence that God spoke directly to all people and not just through ministers and appointed ecclesiastical officials. Not surprisingly, persecution towards Quakers spiked in England in the 1650s and many of them fled the country for other lands. Some even came to Boston, Massachusetts, and began proselytizing, which promptly resulted in banishment from the Colony.
However, the number of Quakers in the colonies continued to grow. In 1659, a group that came to be known as the Boston Martyrs returned to Massachusetts in defiance of the law of banishment that promised death as punishment. You can see where this is headed. All three martyrs were quickly arrested, and two of them, Marmaduke Stephenson and William Robinson, were hanged the same year in Boston. Mary Dyer, the third, was spared at the last minute and deported, but eventually returned and was also hanged a year later, in 1660. A fourth Quaker from Barbados, William Leddra, was hanged in 1661. By then, however, Charles II had regained the throne and was eager to establish a policy of religious tolerance. He forbade the Massachusetts Bay Colony to continue killing Quakers. They grudgingly agreed, but still found other ways to make Quakers miserable until 1684, when the king revoked their charter and installed a royally-appointed governor to administrate the territory.
