Rotherham

The club's roots go back to 1877, when the club was formed as Thornhill Football Club (later Thornhill United). George Cook was the trainer around this time. For many years the leading team in the area was Rotherham Town, who spent three seasons in the Football League while Thornhill United were still playing in the Sheffield & Hallamshire League. By the turn of the century, however, Town had resigned from the Football League and gone out of business; a new club of the same name later joined the Midland League. Meanwhile, Thornhill's fortunes were on the rise to the extent that in 1905 they laid claim to being the pre-eminent club in the town and changed their name to Rotherham County. For a period both clubs competed in the Midland League, finishing first and second in 1911–12. Rotherham County became members of the second division of the Football league in 1919 whilst Rotherham Town failed to become elected to the third division northern section the following year. By 1925 County's fortunes had declined and they had to seek re-election to the third division. By this time it had become clear that to have two professional clubs in the town was not sustainable. Talks had begun in February 1925 and in early May the two clubs merged to form Rotherham United. Days later the reformed club was formally re-elected to the Football League under its new name.

The red and white kit was adopted around 1930 after playing in amber and black, but there was no improvement in the club's fortunes: in 1931 they again had to apply for re-election. Immediately after the Second World War things looked up. The Millers won the only post-war edition of the Football League Third Division North Cup in 1946 beating Chester 5–4 on aggregate. They then finished as runners-up three time in succession between 1947 and 1949 and then were champions of Division Three (North) in 1951. Rotherham reached their highest ever league position of third in the Football League Second Division in 1955, when only goal average denied them a place in the top flight after they finished level on points with champions Birmingham City and runners-up Luton Town. During that season they had notable results including a 6–1 win over Liverpool. In 1961 the Millers beat Aston Villa 2–0 at Millmoor in the inaugural League Cup final first leg; they lost the second leg 3–0 however at Villa Park. The second leg was played the season after due to Villa having a 'Congested Fixture List'. The club held on to its place in Division Two until 1968 and then went into a decline that took them down to Division Four in 1973. In 1975 they were promoted back to the Third Division finishing in the 3rd promotion spot in the Fourth Division. The Millers won the Division Three title in the 1980–81 season, and missed out on a second consecutive promotion by four points, finishing seventh In the second tier (then Division 2) 1981–82. They have not finished this high since. This season also saw Rotherham accomplish their highest-scoring second-tier league double, beating Chelsea 6–0 at home (31 October 1981) and 4–1 away at Stamford Bridge (20 March 1982).

During the 1990s Rotherham were promoted and relegated between the Football League's lowest two divisions and they slipped into the Fourth Division in 1991, just two years after being promoted, but reclaimed their status in the third tier (renamed Division Two for the 1992–93 season due to the launch of the FA Premier League) by finishing third in the Fourth Division in 1992. They survived at this level for five years, never looking like promotion contenders, before being relegated in 1997. In 1996 Rotherham United made their first trip to Wembley, beating Shrewsbury 2–1 to win the Football League Trophy, with two goals from Nigel Jemson giving Rotherham the win, with over 20,000 Rotherham United fans following them. In 1997, just after relegation to Division Three, Ronnie Moore took charge of Rotherham United. His first season ended in a mid-table finish and then his second in a play-off semi-final defeat on penalties to Leyton Orient. In 1999–2000 as Rotherham finished as Division Three runners-up and gained promotion to Division Two, where they finished runners-up and won a second successive promotion.

Rotherham managed to remain in Division One for four seasons, and after relegation to League One in 2005, Mick Harford took over as the Millers' manager, but was sacked after a run of 17 games without a win. Harford was replaced by youth team coach, Alan Knill. Early in 2006 it was announced that the club faced an uncertain future unless a funding gap in the region of £140,000 per month could be plugged. An intervention at the latest possible time by a consortium of local businessmen kept them in business. The final match of the 2005–06 season, home to Milton Keynes Dons, was a winner-take-all relegation showdown where a scoreless draw kept Rotherham up. Rotherham United began their second successive year in League One with a 10-point deficit as a result of the CVA which saved the club from liquidation. The club initially pulled the points back but, after losing key playmaker Lee Williamson and star striker Will Hoskins in the January transfer window, the Millers sat 13 points adrift of safety, making the threat of relegation inevitable. This resulted in Knill being sacked on 1 March, with Mark Robins becoming caretaker manager.

Robins's position was made permanent on 6 April 2007, but he was not able to save Rotherham from relegation. The Millers spent the majority of the 2007–08 season in the automatic promotion places but in mid-March 2008 it was revealed that Rotherham had again entered administration and would be deducted 10 points. Local businessman Tony Stewart then took over as chairman for the 2008–09 season and took the club out of administration via a Creditors Voluntary Agreement, resulting in a 17-point deduction. The Millers were subsequently forced to leave Millmoor, their home of over 100 years, for the Don Valley Stadium in Sheffield, after disputes with the landlords. The Millers had a successful season under the new regime, wiping out the point deficit and being in contention for a play-off place. Rotherham were also involved in two cup runs, reaching the Football League Trophy Northern Final and the League Cup last 16. This included victories over higher league opposition in the form of Wolverhampton Wanderers, Southampton, Sheffield Wednesday, Leicester City and Leeds United.

Mark Robins kept the majority of the team together from the 2008–09 campaign, whilst bolstering his squad with high calibre signings in the form of Nicky Law and the prolific goalscorer Adam Le Fondre. The 2009–10 season started well until Robins controversially departed to rivals Barnsley in September, leaving the Millers at the top of the league. Former manager Ronnie Moore replaced him and led the club to their first ever play-off final and first trip to the new Wembley Stadium, where they lost 3–2 loss. In March 2011, following poor form he left Rotherham by mutual consent, and Andy Scott replaced him until he was sacked in March 2012. Steve Evans succeeded him, in the first season at the New York Stadium, and won promotion by finishing second in League Two. In the 2013–14 League One season, Rotherham gained a place in the League One play-offs, where they defeated Preston North End in the semi-finals to set up a second play-off final at Wembley Stadium in four years. In the final against Leyton Orient, the game went to a penalty shoot-out, where two saves from Adam Collin secured a second successive promotion for the club.

In the 2014–15 Championship season, Rotherham's first after a nine-year absence, their survival was jeopardised by a points deduction for fielding the ineligible Farrend Rawson during their home win against Brighton & Hove Albion, Rawson's loan had expired two days prior to the match, and despite the club insisting it was an external administrative error, they were subsequently thrown back into a relegation battle. Safety was secured in the penultimate game of the season with a 2–1 home victory against Reading. Rotherham sold key players from their promotion winning campaigns before the 2015–16 season, including Ben Pringle, Craig Morgan and Kari Arnason. Evans left the club in September and former Leeds United manager Neil Redfearn was appointed as his replacement, being sacked in February 2016 after a run of six defeats in eight games. Neil Warnock was appointed as manager for the rest of the season, and the club stayed up, finishing 21st. Warnock left the club in May 2016 after not agreeing a contract extension. Alan Stubbs became the new Rotherham boss in June 2016, but was sacked in October. Rotherham replaced Stubbs with Kenny Jackett, who himself was replaced with Paul Warne, as Rotherham finished the season bottom of the league and were relegated to League One. As a result, they finished on 24 points, making them hold the current record for the lowest amount of points in a single season in the second division of English football, beating Blackpool FC and Stockport County’s 26 points finish.

At the first attempt, Rotherham returned to the Championship, defeating Shrewsbury in the 2018 play-off final. Rotherham were relegated from the Championship the following season on the penultimate game of the campaign. In the 2019–20 season, Rotherham were promoted through points per game in 2nd place behind Coventry City. They were relegated back to League One at the end of the 2020–21 season as they suffered an 88th-minute equaliser against Cardiff City, which sent them down at Derby County's expense. In the 2021–22 season, the Millers were promoted back to the Championship as runners-up, defeating Gillingham 2–0 on the final day of the season. The club also won the 2021–22 EFL Trophy at Wembley Stadium after defeating Sutton United 4–2 after extra time. Early in the 2022–23 season, manager Paul Warne departed for Derby County, being replaced by Exeter City boss Matt Taylor. At the end of the 2023–24 season, Rotherham were relegated back to League One.
