Both clubs come from Stoke-on-Trent and are the only clubs from the city to have played in the football league.
Both clubs had strong links to the local pottery industry, Port Vale's unique name being based on the Trent and Mersey Canal and with City's nickname being The Potters.
Port Vale tends to get support from the North of the city, notably Tunstall and Burslem.
this has led to a heated atmosphere at these matches, especially with the rise of football hooliganism and the 'Naughty Forty'.
The two teams have met a total of 185 times, consisting of: 44 The Football League, 6 FA Cup, 62 friendlies, and 73 other (mostly local) cup games.
Vale have had only five seasons playing at a higher level than City, and never in the top flight.
