Sportclub Heerenveen was founded on 20 July 1920 in the town of Heerenveen, Friesland, as Athleta. It changed name twice, first to Spartaan and then to v.v. Heerenveen in 1922. While the Netherlands was occupied by Germany, Heerenveen won three successive North of the Netherlands championships, and following the end of World War II it went on to win the same title six times in a row; the club's dominance partly ascribed to the presence of Abe Lenstra. During this period, Lenstra led Heerenveen to a famous victory over Ajax in one of the most noted games in Dutch domestic football history. Trailing 5–1 with 25 minutes remaining, the Frisian team inexplicably fought back for a 6–5 victory.
