The Declaration of Sports (also known as the Book of Sports) was a declaration of James I of England issued just for Lancashire in 1617, nationally in 1618, and reissued by Charles I in 1633. It listed the sports and recreations that were permitted on Sundays and other holy days.
It was originally issued in consultation with Thomas Morton, bishop of Chester, to resolve a dispute in Lancashire between the Puritans and the gentry (many of whom were Roman Catholics). The initial declaration was just for Lancashire, but in 1618, James made the declaration national. The 1618 declaration has largely the same main text as the 1617 version, but with an additional paragraph at the beginning explaining that the king has decided to make the declaration applicable to the whole of England.
The declaration listed archery, dancing, "leaping, vaulting, or any other such harmless recreation" as permissible sports, together with "May-games, Whitsun-ales and Morris-dances, and the setting up of May-poles". Also allowed: "women shall have leave to carry rushes to the church for the decorating of it, according to their old custom."
Amongst the activities that were prohibited were bear- and bull-baiting, "interludes" and bowling.
On the one hand, the declaration rebuked Puritans and other "precise persons", and was issued to counteract the growing Puritan calls for strict abstinence on the Christian Sabbath (Sabbatarianism). On the other, it condemned Catholics and others who did not attend church services in their parish, as the declaration specified that only people who had first attended divine service were entitled to participate in recreations afterward.
