Celtic FC, is a Scottish football team formed in Glasgow in 1888.  Celtic has been Scottish champions on 52 occasions and has won the Scottish Cup a record 40 times.  It is the only Scottish team to have won the European Cup  Celtic Football Club was formally constituted at a meeting in St. Mary's Church Hall on East Rose Street (now Forbes Street), Calton, Glasgow, by an Irish Marist brother named Brother Walfrid on 6 November 1887. The purpose stated in the official club records as "being to alleviate poverty in Glasgow's East End parishes".  The move was largely inspired by the example of Hibernian F.C. which had been formed out of the immigrant Irish population thirteen years earlier in Edinburgh. Walfrid's own suggestion of the name 'Celtic', was intended to reflect the club's Irish and Scottish roots, and was adopted at the same meeting.  On 28 May 1888, Celtic played their first official match against Rangers and won 5-2 in what was described as a "friendly encounter". At this stage Celtic played in a white shirt with a green collar, only making the switch to their iconic green-and-white hoops in 1903.  

Celtic reached the European Cup Final again in 1970, but were beaten 2–1 by Feyenoord at the San Siro in Milan. The departure of Joch Stein urshed in a period of decline before the arrival of Billy McNeill in 1978 restored the clubs fortunes.  The 1980s however saw the arrival of a new challenge from Aberdeen, now managed by Alex Ferguson, and Dundee United under Jim Smith.  The revival of Rangers fortunes after 1986 saw their bitter rivals equal the run of nine successive titles. A succession of managers came and went without success and things reached a new low when the Bank of Scotland informed Celtic that it was calling in the receivers on Thursday 3 March 1994 as a result of exceeding a £5 million overdraft. However, expatriate businessman Fergus McCann wrested control of the club, and ousted the family dynasties which had controlled Celtic since its foundation. According to media reports, McCann took over the club as little as eighteen minutes before it was to be declared bankrupt.  In order to alleviate the club's considerable financial debt, McCann reconstituted Celtic as a public limited company - Celtic PLC - resulting in one of the most successful stock market flotations in British financial history. The share issue generated £14 million and saw the redevelopment of Celtic Park into a 60,832 all-seater stadium.It was not until the arrival of Martin O’Neill in 2000 that the club re-emerged as dominant force in Scottish football. Under his leadership, Celtic won three SPL championships out of five and in his first season in charge, the team also won the domestic treble, being only the second Celtic manager to do so after Jock Stein. They aslo reached the UEFA Cup final in 2003 which they lost to Portuguese side Porto.  Gordon Strachan replaced O’Neill in June 2005 and won three successive titles before his departure in 2009 to Middlesborough.  He was replaced by Neil Lennon, whose controversial style has led to frequent clashes with the football authorities.  He secured Celtic’s first championship in four years at the end of the 2011-12 season. Since then, Celtic has gone on to dominate Scottish football with the banishment of rivals Rangers to the lower divisons winning back-to-back trebles under Brendan Rodgers. This success continued after Neil Lennon returned in 2019 to lead the club to a third consecutive domestic treble. The following season saw Celtic capture its ninth consecutive title, but Lennon regined in Febuary 2021 with the club training Rangers by 18 points in the League. New manager Ange Postecoglou won the title at his first attempt at the end of the 2021-22 season.
