Editing ADO Den Haag (section)

===1905–1971: ADO===
On 1 February 1905, the club Alles Door Oefening (ADO) was founded in café 'Het Hof van Berlijn' (now: De Paap) in The Hague. In the first years of its existence, the club endured some difficult times as many members refused to pay their fees. ADO started out in the local Haagsche Voetbal Bond, but promoted to the national Nederlandsche Voetbal Bond in 1912. That year they promoted to the third level (3e klasse NVB) and two years later they even earned the championship on that level.

After moving to the [[Zuiderpark Stadion|Zuiderpark stadium]] in 1925, ADO continued to grow to a club of some significance. In 1926, the club earned promotion to the highest national level, the Eerste Klasse. In the following years the red-green-white team struggled not to be relegated at first, but rose to the top of the league at the end of the 1930s. In 1939 the club just missed the class title after losing to [[AFC DWS|DWS]] in Amsterdam. In 1940, the title seemed very close again, but another second-place finish was the highest achievable position after the club saw many players being drafted in the army with [[World War II]] closing in. This time another club from Amsterdam, [[Blauw-Wit Amsterdam|Blauw-Wit]], grabbed the title. In 1941, ADO finally won their class and moved on to the national champion's competition, losing that to [[Heracles Almelo|Heracles]].

In the 1941–42 season, all the stars were aligned, and although the war made everyday life harder and harder, the club seemed undefeatable. After winning their league, often by many goals difference, ADO moved on to the national champion's competition and fought for the title with Heerenveen, AGOVV, Eindhoven and Blauw-Wit. A 5–2 victory over AGOVV finally brought ADO their first national title. In 1943 ADO won another title, amongst others by beating legend [[Abe Lenstra]]'s [[SC Heerenveen|Heerenveen]] 8–2.

The Hague had to wait until the 1960s for more successes from their local club. After [[Ernst Happel]] joined ADO as a coach in 1962, the club worked their way to the top of the league again. They finished third in the final ranking in 1965. In 1963, 1964 and 1966, ADO played in the national cup final, the [[KNVB Cup]], but lost. In 1968, they again reached the final, and this time beat Ajax to win it. In the 1970–71 season, ADO started the league with 17 games undefeated and were at the top of the national league, but ended their season as No. 3.

In 1967, ADO played a summer in North America's [[United Soccer Association]], under the name '''[[San Francisco Golden Gate Gales]]'''. The club finished tied for second in the Western Division.
