Rotterdam was founded in 1888, football in the Netherlands was an upper class sport only. Feyenoord, on the other hand, was founded twenty years later, in the center of the working class district Feijenoord. The difference in culture and background caused a lot of friction between the two sides. The first derby match between Feyenoord and Sparta was a friendly match on 22 May 1921. Since Feyenoord's establishment in 1908, the club was working its way up the Dutch football system steadily. In 1921, Feyenoord promoted to the highest football league in the Netherlands for the first time in its existence, while Sparta just relegated to the lower league. As an official league match was not possible, a friendly match had to be played to decide who really was the best club of Rotterdam. Feyenoord won the match in the Sparta stadium with a 2–4 score, which was the first time Sparta's superiority in Rotterdam was broken. In the season 1922–23, the first official Rotterdam derby between Feyenoord and Sparta was played. Sparta, the most successful Rotterdam club at the time, took its revenge over the friendly loss in the previous season and managed to defeat Feyenoord twice with a 1–0 score. Following Sparta Rotterdam's relegation from the top flight after the season 2009–10, a Rotterdam derby between both clubs in the league disappeared for a few years. The last competitive meeting between the two clubs was in April 2010, with Feyenoord winning the Eredivisie match with a 3–0 score at De Kuip. However, following the promotion of Sparta in 2016, the derby returned to the program. Sparta Rotterdam vs Excelsior derby Such derby involves the two Rotterdam clubs who are currently behind Feyenoord in terms of awards and recent successes. Excelsior is based on Kralingen-Crooswijk (formerly a city of its own), in the eastern part of the city, whereas Sparta hails from Spangen, far closer to the city centre, and they are separated by their respective histories, with Sparta being far more successful in the past, whereas Excelsior being perceived as a newer, less successful side. Such rivalry is therefore not considered a heated one. In June 2010, a Sparta-Excelsior two-legged derby occurred as a final the so-called nacompetitie, the promotion/relegation playoff tournament involving clubs from Eredivisie and Eerste Divisie. Despite Sparta coming from Eredivisie and considered obvious favourites, and Excelsior being instead merely third-placed in the Eerste Divisie
