East Stirlingshire Football Club is a Scottish association football club from Falkirk.

 The league was restarted in 1921–22 and after a solitary season in the third-tier in 1923–24, East Stirlingshire remained in the second-tier until 1932–33 when the club was promoted to the top-tier for the first time but were relegated after one season.
 Between 1939 and 1955, the club spent only three seasons in the Scottish Football League after being refused entry to its second-tier after the end of World War II and did not join again until the 1955–56 when the number of teams in the league was expanded.

 They won their first major trophy when they won the Challenge Cup beating Airdrie United in the final 2-0 with goals from Steve Hislop and David Bingham, and at the end of the season, they won the First Division Championship and securing promotion to the Scottish Premier League.
 However, SPL rules at that time stated that all member clubs must have a stadium with a minimum capacity of 10,000 seats.
 Caledonian Stadium did not and this left the club's board with a dilemma: either to stay in the First Division like Falkirk the previous season or to groundshare with Aberdeen's Pittodrie Stadium, over 100 miles (160 km) away.
 After consulting with supporters, the board decided the sacrifice of one season in Aberdeen would be worthwhile for Premier League football.
