The Puritans were fond of long sermons and much psalm-singing, and shook their heads at all games and light entertainments. The Royalists stopped as much psalm-singing as they could, while they themselves got up Morris dances and May-day games and all kinds of masques and revels. Sometimes they went too far in their desire to oppose the Puritans, and indulged in all sorts of dissipations. Young William Penn, and many other boys at college, thought the Royalists were too dissolute, and leaned toward the Puritan standards; but he was the son of a knight and a courtier, as well as being naturally fond of sports and gayety, and so he did not dress so soberly nor attend so many sermons as some of his college friends. When the king's brother, Henry, Duke of Gloucester, died of smallpox, Oxford University issued a volume of verses, called "Threnodia," on the duke's death, and young William Penn sent in some Latin lines for the volume. In some matters he was a strong king's man, but in others he was more fond of the stricter Puritan notions. Withal he was a fairly good student, a popular young fellow, and something of an athlete. He might very well have graduated and followed his father to the king's court at London had not a new and strange religious party caught his wide-awake attention while he was at college. When William Penn went to Oxford, some people in England were beginning to be called Quakers, or, as they preferred to be known, Friends. They were almost as much opposed to the Puritans as they were to the Royalists, who belonged to the Church of England. They were a religious sect, and more. They refused to pay the tithes or taxes for the support of the Established Church, they refused to take an oath in the law courts, they would wear their hats in court and in the presence of important persons. They called every one by his first name, and would not use any title, even that of Mister; "thee" and "thou" took the place of "you," although those pronouns had customarily only been used to servants. Nothing gave so much offense to a Royalist as to have a Quaker say "thee" or "thou" to him. They preached in taverns and in highways, and walked the streets uttering prophecies of doom in a loud singsong voice. Either because of this trembling mode of speech, or because their leader, George Fox, had bade the magistrates tremble at the word of the Lord, they were called Quakers.
