In 1913, the club crossed the city to Arsenal Stadium in Highbury, becoming close neighbours of Tottenham Hotspur, and creating the North London derby.

He helped introduce the WM formation, floodlights, and shirt numbers;[7] he also added the white sleeves and brighter red to the club's jersey.

With an annual revenue of £367.1m in the 2021–22 season,[9] Arsenal was estimated to be worth US$2.26 billion by Forbes, making it the world's tenth-most valuable football club,[10] while it is one of the most followed on social media.

In October 1886, Scotsman David Danskin and fifteen fellow munitions workers in Woolwich formed Dial Square Football Club, named after a workshop at the heart of the Royal Arsenal complex.

The club had been renamed Royal Arsenal by January 1887,[15][16] and its first home was Plumstead Common,[15] though they spent most of their time playing at the Manor Ground.

[35][36] He also captured generational young talents such as Cliff Bastin and Eddie Hapgood, whilst also lavishing Highbury's high income on stars such as David Jack and Alex James.

[56][57] With new assistant Don Howe and new players such as Bob McNab and George Graham, Mee led Arsenal to their first League Cup finals, in 1967–68 and 1968–69.

The club's only trophy during this time was the 1979 FA Cup, achieved with a last-minute 3–2 victory over Manchester United, in a final is widely regarded as a classic.

New signings Nigel Winterburn, Lee Dixon and Steve Bould had joined the club by 1988 to complete the "famous Back Four", led by homegrown player Tony Adams.

[112] Until the 1960s, a badge was worn on the playing shirt only for high-profile matches such as FA Cup finals, usually in the form of a monogram of the club's initials in red on a white background.

This early example of a corporate logo, introduced as part of Herbert Chapman's rebranding of the club in the 1930s, was used not only on Cup Final shirts but as a design feature throughout Highbury Stadium, including above the main entrance and inlaid in the floors.

[118][119] In 1933, Herbert Chapman, wanting his players to be more distinctly dressed, updated the kit, adding white sleeves and changing the shade to a brighter pillar box red.

[29] The entire stadium was given a massive overhaul in the 1930s: new Art Deco West and East stands were constructed, opening in 1932 and 1936 respectively, and a roof was added to the North Bank terrace, which was bombed during the Second World War and not restored until 1954.

The Taylor Report and Premier League regulations obliged Arsenal to convert Highbury to an all-seater stadium in time for the 1993–94 season, thus reducing the capacity to 38,419 seated spectators.

[29] These limitations prevented the club from maximising matchday revenue during the 1990s and first decade of the 21st century, putting them in danger of being left behind in the football boom of that time.

[140] The stadium was named after its sponsors, the airline company Emirates, with whom the club signed the largest sponsorship deal in English football history, worth around £100 million.

Both the Academy under-18 team and the reserves occasionally play their big games at the Emirates in front of a crowd reduced to only the lower west stand.

[153] Arsenal have the seventh highest average attendance of European football clubs only behind Borussia Dortmund, Barcelona, Manchester United, Real Madrid, Bayern Munich and Schalke 04.

[164] Arsenal's longest-running and deepest rivalry is with their nearest major neighbour, Tottenham Hotspur; matches between the two are referred to as the North London derby.

In addition, Arsenal and Manchester United developed a strong on-pitch rivalry in the late 1980s, which intensified in the early 2000s when both clubs were competing for the Premier League title.

[166][167][168] The club mascot is Gunnersaurus Rex, a smiling, seven-foot-tall green dinosaur, who first appeared at a home match against Manchester City in August 1994 (or 1993).

He is based on a drawing by then-11-year-old Peter Lovell, whose design and another similar idea won a Junior Gunners contest; his official backstory is that he hatched from an egg found during renovations at Highbury.

[169][170][171][172][173][174] The same performer, Jerry Quy, has been inside the suit from the start; in early October 2020, as part of cost-cutting brought about by the COVID-19 pandemic, the club made him redundant from that and his other part-time job in supporter liaison, together with 55 full-time employees, although they later said Gunnersaurus could return after spectators were allowed back in stadiums.

[177][178] In November 2020, in advance of COVID-19 regulations being relaxed to allow supporters to attend home games from 3 December, Arsenal announced that Gunnersaurus would return, to be played by a roster of people that could include Quy if he wished.

[200][203] Sky's coverage of Arsenal's January 2010 match against Manchester United was the first live public broadcast of a sports event on 3D television.

[207] The book was twice adapted for the cinema – the 1997 British film focuses on Arsenal's 1988–89 title win, and a 2005 American version features a fan of baseball's Boston Red Sox.

[209][210] In the 1997 film The Full Monty the principal characters move forward in a line and raise their hands, deliberately mimicking the Arsenal defence's offside trap, in an attempt to co-ordinate their striptease routine.

To promote the event, the club launched an exclusive all white kit that was not commercially available and only awarded to individuals who are making a positive difference in the community.

[267] Declan Rice holds the Arsenal record signing price after a deal with West Ham United was completed in July 2023, for an initial £100 million.

[19][275] Due to the club's original location within the borders of both the London and Kent Football Associations,[276] Arsenal competed in and won trophies organised by each.
