Flower of Scotland was written by Roy Williamson of the folk group The Corries in the 1960s, looking back to Robert the Bruce's victory over England at the Battle of Bannockburn in 1314. The song grew from folk clubs into stadiums, where Scottish rugby and football supporters adopted it as their anthem for international matches. Its simple, defiant chorus makes it easy for a whole crowd to sing together, which is why it remains a powerful symbol of Scottish identity at sporting events and national celebrations today.
