Longbows remained in use until around the 16th century, when advances in firearms made gunpowder weapons a significant factor in warfare and such units as arquebusiers and grenadiers began appearing. Despite this, the English Crown made numerous efforts to continue to promote archery practice by banning other sports and fining people for not possessing bows. Indeed, just before the English Civil War, a pamphlet by William Neade entitled "The Double-Armed Man" advocated that soldiers be trained in both the longbow and pike; although this advice was disregarded by other writers of the day, who accepted that firearms had supplanted the role of archery.
