The mid-1970s were more turbulent. Illingworth and several others had refused to tour India in 1972–73 which led to a clamour for Illingworth's job by the end of that summer – England had just been beaten 2–0 by a flamboyant West Indies side – with several England players well over 35. Mike Denness was the surprising choice but only lasted 18 months; his results against poor opposition were good, but England were badly exposed as ageing and lacking in good fast bowling against the 1974–75 Australians, losing that series 4–1 to lose the Ashes.
This loss saw the resignation of Strauss as captain (and his retirement from cricket). Cook, who was already in charge of the ODI side, replaced Strauss and led England to a 2–1 victory in India – their first in the country since 1984–85. In doing so, he became the first captain to score centuries in his first five Tests as captain and became England's leading century-maker with 23 centuries to his name.
England and Australia were the first teams to play a Test match (15–19 March 1877), and along with South Africa, these nations formed the Imperial Cricket Conference (the predecessor to today's International Cricket Council) on 15 June 1909. England and Australia also played the first ODI on 5 January 1971. England's first T20I was played on 13 June 2005, once more against Australia.
England's first match after the war was in the 1920–21 season against Australia. Still feeling the effects of the war England went down to a series of crushing defeats and suffered their first whitewash losing the series 5–0. Six Australians scored hundreds while Mailey spun out 36 English batsmen. Things were no better in the next few Ashes series losing the 1921 Ashes series 3–0 and the 1924–25 Ashes 4–1. England's fortunes were to change in 1926 as they regained the Ashes and were a formidable team during this period dispatching Australia 4–1 in the 1928–29 Ashes tour.
The England cricket team represents England and Wales. However, under ICC regulations, players can qualify to play for a country by nationality, place of birth or residence, so (as with any national sports team) some people are eligible to play for more than one team. ECB regulations state that to play for England, a player must be a British citizen, and have either been born in England or Wales, or have lived in England or Wales for three years. This has led to players who also held other nationalities becoming eligible to play for England. The qualification period for those born outside England and Wales has varied in the past, but in November 2018 the ECB announced that the period would be reduced to three years in all circumstances, in line with ICC regulations.
