Hull City A.F.C. were founded on 28 June 1904. For some years before these attempts were made to found a football club, but in a city dominated initially by rugby league with the likes of Hull F.C. and Hull Kingston Rovers this proved difficult.
The first season for Hull City consisted of friendly matches; because of the time of founding, City were unable to apply for membership to The Football League for the 1904–05 season. The early matches were played at The Boulevard, home of rugby league side Hull FC. On 1 September 1904, City's debut match took place against Notts County; with 6000 in attendance at the Boulevard, City notched up an impressive start holding the more experienced County to a 2–2 draw.
Hull's first taste of competitive football came in the FA Cup, but they were eliminated, after a replay, in the preliminary round against , the score was 7–4 on aggregate. After uneasy relationships with landlords, Hull City moved to Anlaby Road Cricket Ground.
Finally, after playing 44 friendly fixtures the previous season, Hull City were entered into the Football League Second Division for the 1905–06 season. Other teams competing in the league that season included the likes of Manchester United and Chelsea, as well as Yorkshire rivals Leeds City, Bradford City and Barnsley. Indeed, it was Barnsley who they faced in their first game, beating them 4–1. Eventually, Hull would finish fifth.
The following season a new ground was built for Hull City across the road from the cricket ground. Still under the managership of Ambrose Langley, City continued to finish consistently in the top half of the table. They came agonisingly close to promotion in the 1909–10 season, recording what would be their highest ever finish in their history (a record which will be surpassed at the end of the 2008–09 Premier League season); Hull finishing third, level on points with second placed Oldham Athletic, they missed promotion on goal average by the slim margin of 0.29 of a goal.
