[3] In an effort to gain entry into the Football League, the club invited Scottish architect Archibald Leitch to reconstruct Leeds Road.

After the plans went through, Huddersfield directors successfully applied to become members of the Football League in 1910, and development of Leeds Road began immediately.

[6] During their first season in the top flight, former Leeds City manager Herbert Chapman was brought in (after Huddersfield helped him overturn his ban) as the new assistant to Ambrose Langley.

[9] In the summer of 1921, playmaker Clem Stephenson and the club's all-time top goal scorer George Brown were acquired.

[5] Chapman's tactics were based upon the principles of a strong defence and a fast, counter-attacking response, with the focus on quick, short passing and mazy runs from his wingers.

[19] After winning successive league titles, Chapman left for Arsenal, which offered to double his wages and attracted larger crowds than Huddersfield.

Tom Wilson, Bob Kelly, Billy Smith, and Roy Goodall started for England; Alex Jackson played for Scotland.

[5] A deterioration of their league position followed, although they finished runners-up in 1933–34, and two more FA Cup Finals were reached under new manager Clem Stephenson.

[8][6] Town were defeated in 1930 by Chapman's Arsenal,[25] and in 1938 by Preston North End after extra time, which was the first FA Cup final to be broadcast on television.

[6] The 1974–75 season also saw Huddersfield Town field a black player for the first time with Lloyd Maitland making his first team debut on 8 February 1974 against Hereford United.

[41] Due to Huddersfield languishing at the bottom of the division, declining home attendances, and the resulting financial pressure, Buxton was sacked in December 1986.

[51] Huddersfield Town played their final match at Leeds Road on 30 April 1994, beating Blackpool 2–1, which was watched by a near capacity crowd of 16,195.

[54] Warnock left the club that summer, and was replaced by Brian Horton, who guided the Town to an eighth-place finish the following season.

[60] Huddersfield topped the table in December, but their form plummeted after striker Marcus Stewart was sold in the January transfer window to First Division rivals Ipswich Town.

Rubery accused Bruce of "wasting £3 million", arguing that the money would have been "spent more wisely by a more experienced manager without an ego to feed".

[68] Huddersfield finished in a surprising fourth place,[69] and defeated Mansfield Town in the play-off final to return to the third tier.

[76] German Borussia Dortmund II coach David Wagner became the first person born outside the British Isles to manage the club in November 2015.

[84] Wagner left the club by mutual consent in January 2019, and was replaced by Borussia Dortmund II manager Jan Siewert,[85] but Town were relegated in March with six matches remaining.

[84] Chairman Hoyle announced his departure in May 2019, selling the club to businessman Phil Hodgkinson, relinquishing the post due to poor health.

[87] Siewert was replaced by Lincoln City manager Danny Cowley in September of that year,[88] who guided the club to survival in the Championship before being sacked.

In the first instance, the video assistant referee did not overturn Moss's decision despite apparent contact between Forest's Jack Colback and Huddersfield's Harry Toffolo.

[94] His return to the John Smiths stadium saw a 2–1 win against Birmingham on 18 February 2023 and he was quoted as saying he had 'tears in his eyes' due to the reception he received from the fans.

The deal was subject to "legislative and governance procedures", and involved Hoyle writing off £40 million of debt to keep the club, sitting 22nd in the Championship, out of administration.

[96] On 28 March 2023, the club revealed the bid was from El Dorado Hills, California (United States) investor and owner of USL Championship side Sacramento Republic, Kevin M. Nagle;[97] the deal was completed in June 2023.

[99] However, Huddersfield continued to struggle in the 2023–24 season, parting company with Warnock in September 2023, then appointing Darren Moore as manager, but sacking him in January 2024, after just three wins in 23 matches, with the club 21st in the second tier and three points above the relegation places.

[105] Town stuck with the same principal design (blue and white stripes) until 1966, when Scottish manager Tom Johnston introduced all-blue shirts.

[3] In 2019, Town agreed to have Paddy Power shirt sponsorship in a striking beauty queen style diagonal sash design.

Its aim was "to improve the atmosphere around the stadium on matchdays", and the members were "inspired by fan groups of continental Europe and other parts of the world".

[129][130] Huddersfield Town's main rivals are considered to be West Yorkshire clubs Bradford City and Leeds United.

Several ex-players/managers associated with Huddersfield Town are represented in the English Football Hall of Fame, which was created in 2002, as a celebration of those who have made an outstanding contribution to the game.
