Derby dell'Enza

Before the 1990s, neither side had played in Serie A, Italian football's top tier that was formed in 1929, so Parma's dominance is a recent trend.

Separated by just 25 kilometres, Parma has historically been seen as a snobbish or aristocratic city, the capital of the small state Duchy of Parma and Piacenza, home to monuments, churches and palaces, and whose famous sons are musicians Giuseppe Verdi and Arturo Toscanini and painter Parmigianino, while the residents of Reggio Emilia were perceived as less affluent and hot-blooded with a strong background in agriculture, the first city to fly the Tricolore in 1797, but also excelled in the arts through the works of Ludovico Ariosto and Antonio da Correggio.

However, they returned as the 1960s neared with four seasons of Serie B contests in which the spoils were shared with three wins apiece out of eight, but Parma's relegation from that division in 1961–62 put an end to derbies until 1970.

[16] The return meeting on 6 March 1994 was bizarrely interrupted by a calf injury to referee Pierluigi Pairetto after just 20 minutes, meaning the match was called off at half-time and not completed until 5 April.

[20] A gap had already opened between the fortunes of the club at a time when owner Calisto Tanzi owned Parma and sponsored Reggiana.

[21] Because the match was not played for some years, some have called for its revival as a friendly, but the possibility was denied in the summer of 2010 due to worries about public order.

[2] On 19 December 2016 in Group B of the Lega Pro (soon to be renamed Serie C) and after nearly two decades without a competitive meeting, Parma won the derby with two goals at the Mapei Stadium.

The two clubs have met just once in the Coppa Italia and Reggiana won the game 2–1, scoring the winning goal in extra time.

This is an incomplete list of players who have made at least one appearance for both: Only two coach has taken charge of both Derby dell'Enza outfits: Carlo Ancelotti and Luigi Apolloni.

In the summer of 1996, he moved directly to fellow Serie A team Parma to replace the club's all-time most successful coach, Nevio Scala.

Apolloni played for both clubs in his professional career, then briefly managed Reggiana in the 2012-13 season, where he was appointed mid-season in the 3rd tier and sacked after 9 games.
