List of sports rivalries

A rivalry that gets out of control can lead to fighting, hooliganism, rioting and some instances with career-ending and even fatal consequences.

One of the first known sports rivalries occurred in the Roman Empire between the Blues and the Greens, and the minor teams of the Reds and Whites, each of which were chariot racing clubs competing at the Hippodrome in Constantinople.

One suggestion is that it arose from a game of football played between the congregations of All Saints and St Peter's churches in the city of Derby.

The 19th Earl has since claimed the Derby name was originally only given to one other sporting event: fixtures between St Helens at one end of the family's Knowsley estate and Wigan at the other.

The goals were at Nuns Mill in the north and the Gallows Balk in the south of the town, and much of the action took place in the River Derwent or the Markeaton Brook.
