In the days when flags and banners were important to identify opposing elements in battle, King William I 'The Lion'( 1143 to 1214), adopted a heraldic device showing a rampant lion, the king of beasts, rearing up with three paws stretched out. This became the royal coat of arms in Scotland. The lion was also incorporated into the Great Seal of Scotland which was placed on all official documents.
When the royal coat of arms was being designed, the lion rampant was incorprated, with the Latin motto "Nemo me impune lacessit" meaning "No one attacks me with impunity". In Scots, that became "Wha daur meddle wi' me?"
King George V signed a Royal Warrant in 1934 allowing the use of the Rampant Lion flag as "a mark of loyalty"
because of the forthcoming Jubilee celebrations. The Lord Lyon officially now takes the view that this
permission "related to decorative ebullition", that is, it is permissable to wave the flag,however not allowable to fly the flag without permission, on a flag-pole or from a building. It is used alongside the Saltire, as our 'other' flag as a symbol of Scottish pride, in particular at sporting events, all over the world.
