The Eerste Divisie (, ) is the second-highest tier of football in the Netherlands. It is linked with the top-level Eredivisie and with the third-level Tweede Divisie via promotion/relegation systems. It is also known as the Keuken Kampioen Divisie due to sponsorship, while previously it was known as Jupiler League for the same reason. History The Eerste Divisie consists of 20 clubs, who play each other in a double round-robin league, with each club playing the other club home and away. Each club plays every other club once in the first half of the season before the league takes a winter break around the Christmas and New Year's holiday season. The second half of the season sees the same fixtures as the first half, with the stadiums changed, although the two halves are not played in the same order. At the end of each season, the champion and the runner-up of the Eerste Divisie are automatically promoted to the Eredivisie. Seven other clubs enter the Nacompetitie , a promotion/relegation playoff that includes the 16th-placed club in the Eredivisie. The following teams qualify for the Nacompetitie: The club with the best record in the "first period" of the season (after 8 rounds). The club with the best record in the "second period" of the season (rounds 9–16). The club with the best record in the "third period" of the season (rounds 17–24). The club with the best record in the "fourth period" of the season (rounds 25–32). The two remaining spots are filled at the season's end by the highest-placed clubs that have not already earned automatic promotion or qualified for the Nacompetitie. If the club that wins a period has qualified for the Nacompetitie by winning a previous period, its place is filled by the next-best club in that period that has not already qualified. Usually, the clubs that qualify for the Nacompetitie turn out to be the 3rd- through 9th-placed clubs in the final table. Clubs in the Nacompetitie face each other in a knock-out system with the number 16 of the Eredivisie for one place in next season's Eredivisie. Between seasons 1971–72 and 2008–09 teams could not relegate from the Eerste Divisie. From the 2009–10 season onwards, one team has been relegated from the Eerste Divisie to the Hoofdklasse (then the main amateur league of Dutch football). From the 2010–11 to 2015–16 seasons, the KNVB introduced a third
