In the 19th century, rugby gradually became popular in various colleges in England. The regulatory body for rugby was also established during this period, with the earliest being the Oxford University Rugby League founded in 1846. Rugby is gradually becoming professionalized and a national fitness and entertainment activity. Rugby has a history of over a hundred years, and since the 19th century, this high-intensity sport has undergone several significant developments. In the early stages of rugby development, there were no designated venues or clear rules for assigning responsibilities. With the development of rugby, the rules of the game have gradually improved, and both the field and the referee have been unified.
