In the 16th century, the city of Florence celebrated the period between Epiphany and Lent by playing a game which today is known as "calcio storico" ("historic kickball") in the Piazza della Novere or the Piazza Santa Croce. The young aristocrats of the city would dress up in fine silk costumes and embroil themselves in a violent form of football. For example, calcio players could punch, shoulder charge, and kick opponents. Blows below the belt were allowed. The game is said to have originated as a military training exercise. In 1580, Count Giovanni de' Bardi di Vernio wrote Discorso sopra 'l giuoco del Calcio Fiorentino. This is sometimes said to be the earliest code of rules for any football game. The game was not played after January 1739 (until it was revived in May 1930).

Official disapproval and attempts to ban football
Main article: Attempts to ban football games
Numerous attempts have been made to ban football games, particularly the most rowdy and disruptive forms. This was especially the case in England and in other parts of Europe, during the Middle Ages and early modern period. Between 1324 and 1667, football was banned in England alone by more than 30 royal and local laws. The need to repeatedly proclaim such laws demonstrated the difficulty in enforcing bans on popular games. King Edward II was so troubled by the unruliness of football in London that on April 13, 1314 he issued a proclamation banning it: "Forasmuch as there is great noise in the city caused by hustling over large balls from which many evils may arise which God forbid; we command and forbid, on behalf of the King, on pain of imprisonment, such game to be used in the city in the future."
The reasons for the ban by Edward III, on June 12, 1349, were explicit: football and other recreations distracted the populace from practicing archery, which was necessary for war.
By 1608, the local authorities in Manchester were complaining that: "With the ffotebale...[there] hath beene greate disorder in our towne of Manchester we are told, and glasse windowes broken yearlye and spoyled by a companie of lewd and disordered persons ..."[10] That same year, the word "football" was used disapprovingly by William Shakespeare. Shakespeare's play King Lear contains the line: "Nor tripped neither, you base football player" (Act I, Scene 4). Shakespeare also mentions the game in A Comedy of Errors (Act II, Scene 1):
Am I so round with you as you with me,
That like a football you do spurn me thus?
You spurn me hence, and he will spurn me hither:
If I last in this service, you must case me in leather.
"Spurn" literally means to kick away, thus implying that the game involved kicking a ball between players.
King James I of England's Book of Sports (1618) however, instructs Christians to play at football every Sunday afternoon after worship.[11] The book's aim appears to be an attempt to offset the strictness of the Puritans regarding the keeping of the Sabbath.[12]
