===1971–1996: FC Den Haag===
{{expand section|date=July 2014}}
In 1971 the club merged with city rivals [[Holland Sport]] to form ''FC Den Haag''.

The club again reached the Dutch Cup final in 1972 (this time losing 3–2 to Ajax) then went on to win the trophy for a second time in 1975, this team defeating [[FC Twente|Twente]] 1–0. Their greatest European success was a quarter-final game against [[West Ham United F.C.|West Ham United]] for the European Cup Winners Cup in 1976. A 4–2 win in The Hague followed by a 3–1 defeat in London meant elimination. In the 1980s, FC Den Haag was often associated with hooliganism and financial backfall. However, they reached their fourth Dutch Cup final in 1987, losing 4–2 (again to Ajax) following two extra-time winners from [[Marco van Basten]].

On 3 April 1982, hooligans of the club burned down part of their own home ground, [[Zuiderpark Stadion]].<ref>{{cite web|url=https://www.worldsoccer.com/features/the-tarnishing-of-den-haags-golden-past-368667|title=The tarnishing of Den Haag's golden past|date=20 February 2016|access-date=3 July 2018|archive-date=3 July 2018|archive-url=https://web.archive.org/web/20180703220335/https://www.worldsoccer.com/features/the-tarnishing-of-den-haags-golden-past-368667|url-status=live}}</ref> The fire was set after a 4–0 loss to [[HFC Haarlem]].
