The club were immediately relegated back to the Third Division South the following year at the end of a poor season, but made better progress after Scott Duncan was replaced as team manager by Alf Ramsey in August 1955.

[7][8][9] As English league champions, they qualified for the 1962–63 European Cup, defeating Maltese side Floriana 14–1 on aggregate before losing to AC Milan.

[12] During the summer of 1968, Steve Stacey, signed from fourth division side Wrexham, went on to make his debut on 14 September 1968 becoming the first black player to represent the club in the football league.

[14] In the 1974–75 season they reached the semi-finals of the FA Cup for the first time, losing to West Ham United after a replay, and finished third in the league.

[15] By the late 1970s, Robson had built a strong side with talent in every department, introducing the Dutch pair Arnold Mühren and Frans Thijssen to add flair to a team that featured British internationals including John Wark, Terry Butcher and Paul Mariner, although the Ipswich squad perhaps lacked the depth of established big clubs like Liverpool and Manchester United.

The Football Association lured Robson away from Portman Road a year later, when he accepted their offer to manage the England national team in July 1982.

The recent construction of an expensive new stand at Portman Road limited the club's budget, despite the money gained from sales of key players including Thijssen and Wark.

[36] Lyall's successor, George Burley, was unable to turn team performances around, and Ipswich were dealt a Premiership record defeat, 9–0, at Manchester United, on their way to relegation.

Despite a good run of form in January and February, Burley could not save the club from relegation back to the Championship at the end of the season.

[41] A slow start to the season, culminating in a 0–3 defeat at struggling Grimsby Town, meant that Burley was sacked in October 2002 after nearly eight years as manager.

[43] Royle inherited a side struggling near the Division One relegation zone, but revived fortunes such that the team narrowly failed to reach the playoffs.

[50] In November 2007, the club were involved in takeover discussions with both businessman Marcus Evans and former Birmingham City director David Sullivan.

[54] After failing to reach the playoffs despite substantial investment, Magilton was sacked in April 2009, and new Chief Executive Simon Clegg replaced him with former Manchester United player, Roy Keane.

[55] Keane's spell as manager came to an end after an unsuccessful 18 months, when he was sacked in January 2011, to be replaced briefly by Ian McParland in a caretaker role before Paul Jewell took the reins on a permanent basis.

[56] A poor start to the 2012/13 season with Ipswich bottom of the Championship after winning only one of their first twelve games, led to Jewell leaving his position on 24 October 2012 by mutual consent.

[57] He was replaced temporarily by Chris Hutchings for a single match in a caretaker role, before former Wolves boss Mick McCarthy was appointed full-time on 1 November 2012.

[65] However, after a poor start to the season and with the team bottom of the table, Hurst was sacked in October 2018 after less than five months in charge – making him the shortest serving manager in the club's history.

And to complete the badge I thought of the town of Ipswich which contains many historical buildings, including the Wolsey Gate, and is close to the sea with a large dock area."

All-blue shirts and white shorts were first worn in the 1936–37 season, following the clubs entry into the Southern Football League after turning professional.

[89] In 1981, Ipswich Town announced a sponsorship deal with Japanese-based electronics company Pioneer Corporation, who became the first official sponsors of the club.

The radio station would only sponsor the club's kits for a single season before being replaced with pharmaceutical and horticultural chemical manufacturers Fisons.

In January 2018, the club agreed a new three year sponsorship deal worth almost £2 million with British online casino company Magical Vegas.

[90] In May 2020, Magical Vegas revealed that they had donated the final year of their shirt sponsor rights to The Carers Trust charity for the 2020–21 season.

[1] Success that took place on the pitch led to further investment in the infrastructure, with the club spending over £22 million on redeveloping both North and South stands, resulting in a current capacity of 30,311, making it the largest-capacity football stadium in East Anglia.

[107][108] Former Town manager Jim Magilton commented in the local press that he disliked the nickname and said that it conjured up "images of carrot-crunching yokels",[106] while players such as Matt Holland accepted the chant with good humour.

Allan Hunter won the most international caps whilst a player at the club, making 47 appearances for Northern Ireland during his time at Ipswich.

[121] The academy was particularly successful in the 1990s, producing a number of first-team players including Kieron Dyer, Richard Wright and Titus Bramble.

The inaugural members, Ray Crawford, Mick Mills, Ted Phillips and John Wark, were selected in 2007 by a ballot of former Ipswich players.

[126][127] Information correct as of 24 January 2025[128] League Cup A number of Ipswich players appeared alongside Sylvester Stallone and Pelé in the 1981 prisoner of war film Escape to Victory, including John Wark, Russell Osman, Robin Turner, Laurie Sivell, and Kevin O'Callaghan.
