Background: Wilhelm II (Friedrich Wilhelm Viktor Albert von Hohenzollern; 27 January 1859 - 4 June 1941) was the last German Emperor (Kaiser) and King of Prussia, ruling the German Empire and the Kingdom of Prussia from 15 June 1888 to 9 November 1918. He was the eldest grandchild of the Queen Victoria of the United Kingdom and related to many monarchs and princes of Europe, most notably King George V of the United Kingdom and Emperor Nicholas II of Russia. Acceding to the throne in 1888, he dismissed the Chancellor, Otto von Bismarck, in 1890. He also launched Germany on a bellicose "New Course" in foreign affairs that culminated in his support for Austria-Hungary in the crisis of July 1914 that led in a matter of days to the First World War.
Context: German foreign policy under Wilhelm II was faced with a number of significant problems. Perhaps the most apparent was that Wilhelm was an impatient man, subjective in his reactions and affected strongly by sentiment and impulse. He was personally ill-equipped to steer German foreign policy along a rational course. It is now widely recognised that the various spectacular acts which Wilhelm undertook in the international sphere were often partially encouraged by the German foreign policy elite. There were a number of notorious examples, such as the Kruger telegram of 1896 in which Wilhelm congratulated President Paul Kruger of the Transvaal Republic on the suppression of the British Jameson Raid, thus alienating British public opinion.  British public opinion had been quite favourable toward the Kaiser in his first twelve years on the throne, but it turned sour in the late 1890s. During the First World War, he became the central target of British anti-German propaganda and the personification of a hated enemy.  Wilhelm invented and spread fears of a yellow peril trying to interest other European rulers in the perils they faced by invading China; few other leaders paid attention. Wilhelm used the Japanese victory in the Russo-Japanese War to try to incite fear in the west of the yellow peril that they faced by a resurgent Japan, which Wilhelm claimed would ally with China to overrun the west. Under Wilhelm, Germany invested in strengthening its colonies in Africa and the Pacific, but few became profitable and all were lost during the First World War. In South West Africa (now Namibia), a native revolt against German rule led to the Herero and Namaqua Genocide, although Wilhelm eventually ordered it to be stopped.  One of the few times when Wilhelm succeeded in personal diplomacy was when in 1900 he supported the marriage of Archduke Franz Ferdinand of Austria to Sophie Chotek, against the wishes of Emperor Franz Joseph I of Austria.  A domestic triumph for Wilhelm was when his daughter Victoria Louise married the Duke of Brunswick in 1913; this helped heal the rift between the House of Hanover and the House of Hohenzollern which followed the annexation of Hanover by Prussia in 1866.
Question: when did he gain this position?
Answer: 

Problem: Background: Denis Clive "Denny" Hulme,  (18 June 1936 - 4 October 1992) was a New Zealand racing driver who won the 1967 Formula One World Drivers' Championship for the Brabham team. Between his debut at Monaco in 1965 and his final race in the 1974 US Grand Prix, he started 112 Grand Prix, resulting eight victories and 33 trips to the podium. He also finished third in the overall standing in 1968 and 1972. Hulme showed versatility by dominating the Canadian-American Challenge Cup (Can-Am) for Group 7 sports cars.
Context: In 1966, while driving for the Brabham team in Formula One, Hulme drove in the inaugural season of the Can-Am racing series of FIA Group 7 racing, driving the same Sid Taylor entered Lola T70 he had driven with success in UK Group 7 races that year, but achieving no success in the Can-Am races. In 1967 he joined the McLaren team of New Zealand countryman Bruce McLaren for the series, replacing Chris Amon who had gone to Ferrari. This partnership became so successful, the Americans called them the 'Bruce and Denny Show', such was their domination.  In the 1967 season, the year of his F1 Championship win with Brabham, Hulme finished second to team leader Bruce McLaren for the Can-Am championship, scoring three wins in six races and earning 24 points in the McLaren M6A. Hulme won the Can-Am Championship in 1968, taking three victories in the six race season, earning 35 points in the McLaren M8A. 1969 saw the McLaren team continue to dominate the series; driving the McLaren M8B, they won every race, with multiple 1-2 finishes, and even a 1-2-3 finish when Dan Gurney drove the spare car. Hulme scored five victories in eleven races in 1969, earning 160 points to finish second to teammate McLaren in the championship.  The 1970 season was a difficult one for the team, as they mourned the loss of leader Bruce McLaren, who had died while pre-season testing the McLaren M8D "Batmobile" at the Goodwood Circuit. Teamed first with driver Dan Gurney, then with driver Peter Gethin, Hulme led the team with six wins in ten races, winning his second Can-Am Championship driving the M8D to 132 points--more than double the number of the second-place competitor. For the 1971 season Hulme's teammate was his good friend Peter Revson, who took the Can-Am crown that year with Hulme in second (three wins in ten races), driving the McLaren M8F. In his final season, Hulme drove the McLaren M20 to second place in the 1972 championship on 65 points, with two wins in the nine race season.  Following his quiet start in the 1966 season, Hulme scored 22 wins with 11 second place and 2 third-place finishes in 52 Can-Am races from 1967 through 1972 - standing on the podium for 67% of the races during those six seasons. In those same six seasons, he was the Can-Am season champion twice, and championship runner-up four times. His 22 career wins are the most by any driver in the Can-Am series.
