Year (Source) new or changed laws (proposing club, if known)
1st century 19th century The early rules and regulations of English public schools and universities do not give any information about players‘ equipment except for the colour of their clothing. However, coloured drawings of football matches from the half century of the 19th century show that jerseys, overknee length shorts and boots were already used as clothing. If the jersey and shorts were not uniform or similar in colour, the teams wore different caps or one team wore a (non-uniform) cap, the other has none. So spectators could recognize the players, the colour of their caps was printed in newspaper reports in addition to the names of the players. 1)Cf.
