A pivotal moment in horse racing history, and in the history of Newmarket, occurred in 1665 when, on 16th October 1665, King Charles II issued an Article for a race, the Newmarket Town Plate, for horses carrying 12 stone over the Newmarket Round Course on the second Thursday in October each year. Although there was no Jockey Club at this stage, this is one of the first sets of rules governing a race in Newmarket. It is clear that, at this point in time, there is a Clerk of the Course, a Clerk of the Race, a Treasurer, many Judges, one of whom is responsible for checking the weights of riders.
