Celtic FC: The Complete History

Celtic Football Club was founded on 6 November 1887 — officially beginning play in 1888 — by Brother Walfrid, a Marist Brother and headmaster at Sacred Heart School in the Calton area of Glasgow's East End. His purpose was practical and urgent: to raise money to feed the children of Irish Catholic immigrant families who had settled in the city's most overcrowded parishes.

The Irish famine of the 1840s had driven hundreds of thousands of people to Glasgow. By the 1880s, a dense Irish Catholic community had formed in the East End, living in extreme poverty. Brother Walfrid believed a football club could generate the income to fund the Poor Children's Dinner Table charity. He was right. Celtic's first match raised enough to feed hundreds of children.

The name was chosen to reflect the shared heritage of Ireland and Scotland — the Celtic peoples of both nations. From the beginning, the club carried an identity rooted in immigration, Catholicism, and solidarity with the poor. That identity has shaped Celtic's relationship with its supporters ever since.

Celtic's home ground is Celtic Park in the Parkhead area of Glasgow's East End — less than two miles from where the club was founded. It is known to supporters as Paradise, a name with roots in the club's Irish Catholic heritage and its garden-like early appearance.

The current stadium was largely rebuilt in the 1990s into a modern, all-seated arena. Celtic Park holds 60,832 supporters, making it the largest club stadium in Scotland and one of the largest in the United Kingdom. On European nights in particular, the atmosphere Celtic Park generates is regarded as one of the most intense in world football.

Celtic won their first Scottish league title in 1893 and quickly established themselves as one of the two dominant forces in Scottish football alongside Rangers. The rivalry between the two clubs — the Old Firm — became the defining feature of Scottish football, drawing its intensity from the social and religious divisions of the city as much as from competition on the pitch.

In 1927, Celtic signed John Thomson, a goalkeeper from Fife who became one of the most gifted players of his generation. In September 1931, during an Old Firm match at Ibrox, Thomson dived at the feet of Rangers forward Sam English and suffered a fatal skull fracture. He died that evening, aged twenty-two. Thomson is still mourned by Celtic supporters as the "prince of goalkeepers", and his grave in Fife remains a place of pilgrimage.

Celtic's modern era begins with Jock Stein. A former Celtic player who had captained the club to the league and cup double in 1954, Stein was appointed manager in March 1965 when Celtic were a struggling, underperforming club far from the top of Scottish football.

What followed was one of the most remarkable managerial achievements in the history of the sport. Within a year, Celtic had won the Scottish Cup. Within two years, they had won the European Cup. Stein rebuilt the club from the ground up — tactically, physically, and psychologically — transforming a provincial Scottish club into the best team in Europe.

Stein's Celtic were notable not just for what they won but for how they won it. Every player in his most celebrated team was born within thirty miles of Glasgow. These were local men who understood what the club meant to its community. Stein gave them organisation, belief, and a style of football — attacking, fluid, relentless — that was ahead of its time.

On 25 May 1967, Celtic became the first British club to win the European Cup, beating Internazionale 2–1 in the Estádio Nacional in Lisbon. The team became known immediately as the Lisbon Lions.

Inter, managed by Helenio Herrera, were the masters of catenaccio — a defensive system built around discipline, organisation, and the suppression of the opposition. They took the lead through a Sandro Mazzola penalty after seven minutes and retreated into their shape. Celtic attacked from the first minute to the last.

Tommy Gemmell equalised with a thunderous long-range strike in the 63rd minute. Stevie Chalmers redirected a Bobby Murdoch shot into the net six minutes from time. Celtic had won. The celebrations in Lisbon and across Glasgow were scenes that supporters still describe as the greatest day in the club's history.

The achievement carries a detail that is unique in European football: every member of the squad — not just the starting eleven, but every player involved — was born within thirty miles of Celtic Park. No club that has won the European Cup or Champions League before or since can claim the same.

Between 1965–66 and 1973–74, Celtic won nine consecutive Scottish league championships — a record at the time and a standard of sustained domestic dominance unmatched in Scottish football history until Celtic themselves matched it five decades later.

The nine-in-a-row side contained players who became legends of the club: goalkeeper Ronnie Simpson, full-back Tommy Gemmell, captain Billy McNeill, midfielder Bobby Murdoch, winger Jimmy Johnstone, and striker Bobby Lennox. Jinky Johnstone — small, red-haired, and utterly unpredictable — is widely regarded as the greatest Celtic player of all time and one of the finest wingers ever to play in Britain.

The run came to an end in 1974–75 when Rangers won the title. Jock Stein remained as Celtic manager until 1978, winning further trophies, before leaving for Leeds United and subsequently taking charge of the Scotland national team. He died of a heart attack at the final whistle of Scotland's World Cup qualifier against Wales in Cardiff in September 1985.

Celtic's most successful modern period before the contemporary era came under Martin O'Neill, appointed manager in 2000. With a squad built around the extraordinary Henrik Larsson — a Swedish striker who became perhaps the most complete player Celtic Park has ever seen — O'Neill's Celtic won three league titles, three Scottish Cups, and reached the UEFA Cup Final in 2003.

The Seville final against Porto, managed by José Mourinho, is one of the great occasions in Celtic's history even in defeat. Over 80,000 Celtic supporters travelled to Spain — one of the largest sporting migrations in the history of British football — to watch a 3–2 extra-time defeat that is still remembered as much for the supporters' behaviour as the result. Celtic were awarded UEFA's Fair Play Award for the conduct of their fans.

Larsson left Celtic in 2004 after seven seasons, having scored 242 goals in all competitions and won four league titles, three Scottish Cups, and two League Cups. A statue of him stands outside Celtic Park. He remains the standard by which all subsequent Celtic strikers are measured.

Between 2011–12 and 2019–20, Celtic won nine consecutive Scottish Premiership titles — matching Jock Stein's record from the 1960s and 70s. The peak of that era came under Brendan Rodgers, who managed the club from 2016 to 2019.

In 2016–17, 2017–18, and 2018–19, Celtic won three consecutive domestic trebles — the league, Scottish Cup, and League Cup in each season. The achievement was unprecedented in Scottish football: nine trophies from nine attempts across three seasons. Celtic supporters called it the treble treble.

The attempt at ten consecutive league titles in 2020–21 ended when Rangers, under Steven Gerrard, went the entire season unbeaten. Celtic's nine-in-a-row came to an end, exactly mirroring the fate of Stein's original run. Nine titles. Then stopped.

Celtic have won 54 Scottish league titles, 42 Scottish Cups, and 21 League Cups — making them the most decorated club in Scottish football history by number of trophies. They are the only Scottish club to have won the European Cup.

Celtic Park holds 60,832 supporters and is the largest club stadium in Scotland. The club's global supporter base — particularly in Ireland, the United States, Canada, and Australia — reflects the Irish diaspora from which the club was born in 1888.
