In 1904, [[Gus Mears]] acquired the [[Stamford Bridge (stadium)|Stamford Bridge]] athletics stadium in [[Fulham]] with the aim of turning it into a football ground. An offer to lease it to nearby [[Fulham F.C.]] was turned down, so Mears opted to found his own club to use the stadium. As there was already a team named Fulham in the borough, the name of the adjacent borough of [[Metropolitan Borough of Chelsea|Chelsea]] was chosen for the new club; names like ''Kensington FC'', ''Stamford Bridge FC'' and ''London FC'' were considered.<ref>{{cite book |last=Glanvill |first=Rick |title=Chelsea FC: The Official Biography |year=2006 |page=55 }}</ref> Chelsea F.C. was founded on 10 March 1905 at The Rising Sun pub (now The Butcher's Hook),<ref name="teamhistory">{{cite web |title=Team History – Introduction |url=http://www.chelseafc.com/page/TeamHistory/0,,10268,00.html |url-status=dead |archive-url=https://web.archive.org/web/20110527214035/http://www.chelseafc.com/page/TeamHistory/0%2C%2C10268%2C00.html |archive-date=27 May 2011 |access-date=11 May 2011 |publisher=Chelsea FC }}</ref><ref>{{cite web |date=30 September 2004 |title=The Birth of a Club |url=http://www.chelseafc.com/the-club/club-history/1900.html |url-status=live |archive-url=https://web.archive.org/web/20151218090652/http://www.chelseafc.com/the-club/club-history/1900.html |archive-date=18 December 2015 |access-date=16 December 2015 |publisher=Chelsea FC }}</ref><ref name="capacity">{{cite web |date=18 January 2018 |title=General Club Information |url=https://www.chelseafc.com/en/about-chelsea/about-the-club/general-club-information |access-date=31 May 2021 |website=ChelseaFC.com |archive-date=13 February 2022 |archive-url=https://web.archive.org/web/20220213000549/https://www.chelseafc.com/en/about-chelsea/about-the-club/general-club-information |url-status=live }}</ref> opposite the present-day main entrance to the ground on [[Fulham Road]], and were elected to the Football League shortly afterwards.<ref>{{Cite web |title=Origin.html |url=https://home.adelphi.edu/~ro22316/Origin.html |access-date=2025-05-31 |website=home.adelphi.edu}}</ref>

Chelsea won promotion to the First Division in their second season, and yo-yoed between the First and Second Divisions in its early years.

=== Modernisation and the first league championship (1952–1983) ===

[[File:ChelseaFC League Performance.svg|thumb|Chart showing the progress of Chelsea's league finishes from 1906 to the present]]
Former [[Arsenal F.C.|Arsenal]] and England centre-forward [[Ted Drake]] was appointed manager in 1952 and proceeded to modernise the club. He removed the club's [[Chelsea pensioner]] crest, improved the youth set-up and training regime, rebuilt the side with shrewd signings from the lower divisions and amateur leagues, and led Chelsea to their first major trophy success – the League championship – in [[1954–55 Chelsea F.C. season|1954–55]]. The following season saw UEFA create the [[UEFA Champions League|European Champions' Cup]], but after objections from [[The Football League]], Chelsea were persuaded to withdraw from the competition before it started.<ref>{{cite news |last=Glanville |first=Brian |author-link=Brian Glanville |date=27 April 2005 |title=The great Chelsea surrender |work=[[The Times]] |location=UK |url=https://www.thetimes.com/article/the-great-chelsea-surrender-pz008ngvs85 |url-status=live |access-date=29 December 2006 |archive-url=https://web.archive.org/web/20131212125949/http://www.thetimes.co.uk/tto/sport/football/europe/article2327902.ece |archive-date=12 December 2013 }}</ref><ref>{{cite book |url=https://archive.org/details/chelseafcofficia0000glan/page/254/mode/2up |page=254 |title=Chelsea FC: The Official Biography |first=Rick |last=Glanvill |year=2005 |publisher=Headline |location=London |isbn=0755314654 }}</ref> Chelsea failed to build on this success, and spent the remainder of the 1950s in mid-table. Drake was dismissed in 1961 and replaced by player-coach [[Tommy Docherty]].

Docherty built a new team around the group of talented young players emerging from the club's youth set-up, and Chelsea challenged for honours throughout the 1960s, enduring several near-misses. They were on course for a treble of League, FA Cup and League Cup going into the final stages of the 1964–65 season, winning the [[EFL Cup|League Cup]] but faltering late on in the other two.<ref>{{Cite book |last=Glanvill |first=Rick |title=Chelsea FC: The Official Biography – The Definitive Story of the First 100 Years |publisher=Headline Book Publishing Ltd |year=2006 |isbn=978-0-7553-1466-9 |page=196 }}</ref> In three seasons the side were beaten in three major semi-finals and were FA Cup runners-up. Under Docherty's successor, [[Dave Sexton]], Chelsea won the [[1970 FA Cup final|FA Cup in 1970]], beating [[Leeds United F.C.|Leeds United]] 2–1 in a final replay. The following year, Chelsea took their first European honour, a [[UEFA Cup Winners' Cup]] triumph, with another replayed win, this time over [[Real Madrid CF|Real Madrid]] in Athens.

=== Redevelopment and financial crisis (1983–2003) ===
{{Main|History of Chelsea F.C. (1983–2003)}}
The late 1970s through to the '80s was a turbulent period for Chelsea. An ambitious redevelopment of Stamford Bridge threatened the financial stability of the club,<ref>{{Cite book |last=Glanvill |first=Rick |title=Chelsea FC: The Official Biography |year=2006 |pages=84–87 }}</ref> star players were sold and the team were relegated. Further problems were caused by a notorious [[hooliganism|hooligan]] element among the support, which was to plague the club throughout the decade.<ref>{{Cite book |last=Glanvill |first=Rick |title=Chelsea FC: The Official Biography |year=2006 |pages=143–157 }}</ref> In 1982, at the nadir of their fortunes, Chelsea were acquired by [[Ken Bates]] from Mears' great-nephew [[Brian Mears]], for the nominal sum of £1. Bates bought a controlling stake in the club and floated Chelsea on the [[Alternative Investment Market|AIM]] stock exchange in March 1996<ref name="Football Economy">{{Cite web |title=UK Football Clubs on the UK Stock Markets |url=http://www.footballeconomy.com/stats/stats_turnover_09.htm |url-status=live |archive-url=https://web.archive.org/web/20120705033422/http://www.footballeconomy.com/stats/stats_turnover_09.htm |archive-date=5 July 2012 |access-date=26 June 2012 |publisher=Football Economy }}</ref> although by now the Stamford Bridge freehold had been sold to property developers, meaning the club faced losing their home.<ref>{{Cite book |last=Glanvill |first=Rick |title=Chelsea FC: The Official Biography |year=2006 |pages=89–90 }}</ref> On the pitch, the team had fared little better, coming close to relegation to the [[Football League Third Division|Third Division]] for the first time, but in 1983 manager [[John Neal (footballer, born 1932)|John Neal]] put together an impressive new team for minimal outlay. Chelsea won the [[Football League Second Division|Second Division]] title in 1983–84 and established themselves in the top division with two top-six finishes, before being relegated again in 1988. The club bounced back immediately by winning the Second Division championship in 1988–89.

After a long-running legal battle, Bates reunited the stadium freehold with the club in 1992 by doing a deal with the banks of the property developers, who had been bankrupted by a market crash.<ref>{{Cite book |last=Glanvill |first=Rick |title=Chelsea FC: The Official Biography |year=2006 |pages=90–91 }}</ref> In the mid-1990s Chelsea fan and businessman [[Matthew Harding]] became a director and loaned the club £26&nbsp;million to build the new North Stand and invest in new players.<ref name="The battle of Stamford Bridge">{{Cite news |date=11 November 1995 |title=The battle of Stamford Bridge |work=The Independent |url=https://www.independent.co.uk/sport/the-battle-of-stamford-bridge-1581435.html |url-status=live |access-date=20 July 2019 |archive-url=https://web.archive.org/web/20190720111742/https://www.independent.co.uk/sport/the-battle-of-stamford-bridge-1581435.html |archive-date=20 July 2019 }}</ref> Chelsea's form in the new Premier League was unconvincing, although they did reach the [[1994 FA Cup final]]. The appointment of [[Ruud Gullit]] as player-manager in 1996 began an upturn in the team's fortunes. He added several top international players to the side and led the club to their first major honour since 1971, the [[1997 FA Cup final|FA Cup]]. Gullit was replaced by [[Gianluca Vialli]], whose reign saw Chelsea win the [[1998 Football League Cup final|League Cup]], the [[1998 UEFA Cup Winners' Cup final|UEFA Cup Winners' Cup]] and the [[1998 UEFA Super Cup|UEFA Super Cup in 1998]], and the [[2000 FA Cup final|FA Cup in 2000]]. They mounted a strong title challenge in 1998–99, finishing four points behind champions Manchester United, and made their first appearance in the [[UEFA Champions League]]. Vialli was sacked in favour of [[Claudio Ranieri]], who guided Chelsea to the [[2002 FA Cup final]] and Champions League qualification in 2002–03.

==Stadium==
{{Main|Stamford Bridge (stadium)}}
[[File:Stamford Bridge - West Stand.jpg|thumb|250px|[[Stamford Bridge (stadium)|Stamford Bridge]], West Stand]]
Chelsea have only had one home ground, Stamford Bridge, where they have played since the team's foundation. The stadium was officially opened on 28 April 1877 and for the next 28 years it was used by the [[London Athletic Club]] as an arena for athletics meetings. In 1904, the ground was acquired by businessman [[Gus Mears]] and his brother [[Joseph Mears|Joseph]], who had purchased nearby land (formerly a large market garden) with the aim of staging football matches on the now 12.5&nbsp;acre (51,000&nbsp;m<sup>2</sup>) site.<ref name="stadium" /> Stamford Bridge was designed for the Mears family by the noted football architect [[Archibald Leitch]], who had designed [[Ibrox Stadium|Ibrox]], [[Craven Cottage]] and [[Hampden Park]].<ref>{{Cite book |last=Glanvill |first=Rick |title=Chelsea FC: The Official Biography |year=2006 |pages=69–71 }}</ref> Most football clubs were founded first, and then sought grounds in which to play, but Chelsea were founded for Stamford Bridge.

Starting with an open bowl-like design and one grandstand with seating, Stamford Bridge had an original capacity of around 100,000, making it the second biggest stadium in England after [[Crystal Palace National Sports Centre|Crystal Palace]].<ref name="stadium" /> The early 1930s saw the construction of a terrace on the southern part of the ground with a roof that covered around 20% of the stand. As the roof resembled that of a corrugated iron shed, the stand eventually became known as the "Shed End", although it is unknown who first coined this name. From the 1960s, it became known as the home of Chelsea's most loyal and vocal supporters.<ref name="stadium">{{Cite web |title=Stadium History – Introduction |url=http://www.chelseafc.com/page/StadiumHistory/0,,10268,00.html |url-status=dead |archive-url=https://web.archive.org/web/20120512170633/http://www.chelseafc.com/page/StadiumHistory/0%2C%2C10268%2C00.html |archive-date=12 May 2012 |access-date=20 May 2012 |website=chelseafc.com |publisher=Chelsea FC }}</ref> In 1939, another small seated stand was added, the North Stand, which remained until its demolition in 1975.<ref name="stadium" />

In the early 1970s, the club's owners announced a modernisation of Stamford Bridge with plans for a state-of-the-art 50,000 all-seater stadium.<ref name="stadium" /> Work began in 1972 but the project was beset with problems and ultimately only the East Stand was completed; the cost brought the club close to bankruptcy. The [[Fee simple|freehold]] was sold to property developers and the club were under threat of eviction from the stadium.<ref name="stadium" /> Following a long legal battle, it was not until the mid-1990s that Chelsea's future at Stamford Bridge was secured and renovation work resumed.<ref name="stadium" /> The north, west and southern parts of the ground were converted into all-seater stands and moved closer to the pitch, a process completed by 2001. The East Stand was retained from the 1970s development. In 1996, the north stand was renamed the [[Matthew Harding]] stand, after the club director and benefactor who was killed in a helicopter crash earlier that year.<ref>{{Cite web |title=Matthew Harding Remembered |url=https://www.chelseafc.com/en/news/2018/10/22/matthew-harding-remembered |url-status=live |archive-url=https://web.archive.org/web/20190701203944/https://www.chelseafc.com/en/news/2018/10/22/matthew-harding-remembered |archive-date=1 July 2019 |access-date=1 July 2019 |website=chelseafc.com }}</ref>
[[File:Chelsea-ilkmac.jpg|frame|Chelsea ''vs.'' [[West Bromwich Albion F.C.|West Bromwich Albion]] at Stamford Bridge on 23 September 1905; Chelsea won 1–0.]]
When Stamford Bridge was redeveloped in the [[Ken Bates|Bates]] era many additional features were added to the complex including two [[Millennium & Copthorne Hotels|Millennium & Copthorne hotels]], apartments, bars, restaurants, the Chelsea Megastore, and an interactive visitor attraction called Chelsea World of Sport. The intention was that these facilities would provide extra revenue to support the football side of the business, but they were less successful than hoped and before the Abramovich takeover in 2003 the debt taken on to finance them was a major burden on the club. Soon after the takeover a decision was taken to drop the "Chelsea Village" brand and refocus on Chelsea as a football club. However, the stadium is sometimes still referred to as part of ''"Chelsea Village"'' or ''"The Village"''.

The Stamford Bridge [[Freehold (law)|freehold]], the [[Association football pitch|pitch]], the turnstiles and Chelsea's [[naming rights]] are now owned by [[Chelsea Pitch Owners]], a non-profit organisation in which fans are the shareholders. The CPO was created to ensure the stadium could never again be sold to developers.

==Identity==

===Crest===
Chelsea has had four main [[Crest (sports)|crests]], which all underwent minor variations. The first, adopted when the club was founded, was the image of a [[Chelsea Pensioner]], the army veterans who reside at the nearby [[Royal Hospital Chelsea]]. This contributed to the club's original "pensioner" nickname, and remained for the next half-century, though it never appeared on the shirts. When [[Ted Drake]] became Chelsea manager in 1952, he began to modernise the club. Believing the Chelsea pensioner crest to be old-fashioned, he insisted that it be replaced.<ref name="crest">{{cite book |last=Glanvill |first=Rick |title=Chelsea FC: The Official Biography |year=2006 |page=42 }}</ref> A stop-gap badge which comprised the initials C.F.C. was adopted for a year. In 1953, the club crest was changed to an upright blue lion looking backwards and holding a [[crosier|staff]]. It was based on elements in the [[coat of arms]] of the [[Metropolitan Borough of Chelsea]]<ref>{{Cite web |title=Chelsea Metropolitan Borough Council |url=http://www.civicheraldry.co.uk/lcc.html#chelsea%20bc |url-status=live |archive-url=https://web.archive.org/web/20170804215135/http://www.civicheraldry.co.uk/lcc.html#chelsea%20bc |archive-date=4 August 2017 |access-date=21 January 2007 |website=Civic Heraldry of England and Wales }}</ref> with the "lion rampant regardant" taken from the arms of then club president [[Charles Cadogan, 8th Earl Cadogan|Viscount Chelsea]] and the staff from the [[Westminster Abbey|Abbots of Westminster]], former Lords of the Manor of Chelsea. It featured three red roses, to represent England, and two footballs.<ref name="crest" /> This was the first Chelsea crest to appear on the shirts, in the early 1960s. In 1975, a [[heraldic badge]] was granted by the [[College of Arms]] to the [[English Football League]] for use by Chelsea. The badge took the form of the familiar lion and staff encircled by a blue ring but without lettering and without the red roses and red footballs ([[blazon]]ed as "''A lion rampant reguardant azure supporting with the forepaws a [[crozier]] or all within an annulet azure''").<ref>{{cite journal |last=Phillips |first=David Llewelyn |date=Spring 2015 |title=Badges and 'Crests': The Twentieth-Century Relationship Between Football and Heraldry |url=https://www.theheraldrysociety.com/wp-content/uploads/2019/10/CoA-229-Phillips-paper.pdf |archive-url=https://web.archive.org/web/20210122114341/https://www.theheraldrysociety.com/wp-content/uploads/2019/10/CoA-229-Phillips-paper.pdf |archive-date=22 January 2021 |url-status=live |journal=The Coat of Arms |volume=XI Part I |issue=229 |pages=40–42 |doi= |access-date=31 January 2022 }}</ref> In 1986, with [[Ken Bates]] owner of the club, Chelsea's crest was changed again as part of another attempt to modernise and because the old rampant lion badge could not be trademarked.<ref>{{Cite web |title=1980s Summary |url=http://www.chelseafc.com/the-club/club-history/1980.html |url-status=live |archive-url=https://web.archive.org/web/20150924105033/http://www.chelseafc.com/the-club/club-history/1980.html |archive-date=24 September 2015 |access-date=3 December 2015 |publisher=Chelsea FC }}</ref> The new badge featured a more naturalistic non-heraldic lion, in white and not blue, standing over the C.F.C. initials.

For the centenary season this was accompanied by the words '100 Years' and 'Centenary 2005–2006' on the top and bottom of the crest respectively.<ref name="new crest">{{Cite news |date=12 November 2004 |title=Chelsea centenary crest unveiled |work=BBC Sport |url=https://news.bbc.co.uk/sport2/hi/football/teams/c/chelsea/4008257.stm |url-status=live |access-date=2 January 2007 |archive-url=https://web.archive.org/web/20160112084124/http://news.bbc.co.uk/sport1/hi/football/teams/c/chelsea/4008257.stm |archive-date=12 January 2016 }}</ref>

==Ownership and finances==
[[File:Todd Boehly Autumn 2024.jpg|thumb|upright|[[Todd Boehly]], chairman and one of the co-owners of Chelsea since 2022]]

===Early years===
Chelsea Football Club was founded by [[Gus Mears]] in 1905. After his death in 1912, his descendants continued to own the club until 1982, when [[Ken Bates]] bought the club from Mears' great-nephew [[Brian Mears]] for £1. Bates bought a controlling stake in the club and floated Chelsea on the [[Alternative Investment Market|AIM]] stock exchange in March 1996.<ref name="Football Economy"/> In the mid-1990s Chelsea fan and businessman [[Matthew Harding]] became a director, and loaned the club £26&nbsp;million to build the new North Stand and invest in new players.<ref name="The battle of Stamford Bridge"/>

===Abramovich era===
In July 2003, [[Roman Abramovich]] purchased just over 50% of Chelsea Village plc's share capital, including Bates' 29.5% stake, for £30&nbsp;million and over the following weeks bought out most of the remaining 12,000 shareholders at 35 pence per share, completing a £140&nbsp;million takeover. Other shareholders at the time of the takeover included the [[Matthew Harding]] estate (21%), [[BSkyB]] (9.9%) and various anonymous offshore trusts.<ref>{{Cite news |date=7 February 2003 |title=Bates sells off Chelsea to a Russian billionaire |work=The Daily Telegraph |url=https://www.telegraph.co.uk/sport/football/2406994/Bates-sells-off-Chelsea-to-a-Russian-billionaire.html |url-status=live |access-date=27 June 2012 |archive-url=https://web.archive.org/web/20190630210353/https://www.telegraph.co.uk/sport/football/2406994/Bates-sells-off-Chelsea-to-a-Russian-billionaire.html |archive-date=30 June 2019 }}</ref>
