Nemo Me Impune Lacessit

Nemo me impune lacessit was the Latin motto of the Royal Stuart dynasty of Scotland from at least the reign of James VI when it appeared on the reverse side of merk coins minted in 1578 and 1580. It is the adopted motto of the Order of the Thistle and of three Scottish regiments of the British Army. The motto also appears, in conjunction with the collar of the Order of the Thistle, in later versions of the Royal coat of arms of the Kingdom of Scotland and subsequently in the version of the Royal coat of arms of the United Kingdom used in Scotland. It means No one "cuts" (attacks/assails) me with impunity, and has been loosely rendered in Scots as Wha daur meddle wi me? (in Scottish Gaelic Cha togar m' fhearg gun dìoladh, Scottish Gaelic pronunciation: [xa t̪okəɾ mɛɾak kuɲ tʲiəl̪ˠəɣ]). It is also alternatively translated into English as No one can harm me unpunished.

The motto of the Most Ancient and Most Noble Order of the Thistle, the Scottish chivalrous order, is also that of the British Army regiments The Royal Regiment of Scotland, Scots Guards and Royal Scots Dragoon Guards. It was also the motto of several former units of the British Army, including the Royal Scots, Royal Scots Greys, Royal Highland Fusiliers and Black Watch, some of which went on to be amalgamated to form the Royal Regiment of Scotland in 2006. The motto is also that of the Royal Company of Archers and has been displayed upon the unit's second standard since 1713, following the grant of a Royal charter by Queen Anne.
