The 1687 warrant states that during a battle in 786 with Angles under Aethelstan, the cross of St Andrew appeared in the sky to Achaius, King of Scots after his victory, he established the Order of the Thistle and dedicated it to the saint. The claim that James VII was reviving an earlier Order is generally not supported by the evidence.

John Drummond, 1st Earl of Melfort in 1688 originator of the 'revived' Order In 1783 an Irish equivalent, the Most Illustrious Order of St Patrick, was founded, but it is now dormant. Its equivalent in England, the Most Noble Order of the Garter, is the oldest documented order of chivalry in the United Kingdom, dating to the middle fourteenth century. The Order of the Thistle, which pertains to Scotland, is the second most senior in precedence. Most British orders of chivalry cover the whole United Kingdom, but the three most exalted ones each pertain to one constituent country only. The patron saint of the Order is St Andrew. The same motto appears on the royal coat of arms of the United Kingdom for use in Scotland and pound coins minted in 1984, 1989, 1994, and 1999 (since withdrawn), and is also the motto of the Royal Scots Dragoon Guards, the Scots Guards, the Royal Regiment of Scotland, and The Black Watch (Royal Highland Regiment) of Canada. The motto is Nemo me impune lacessit ( Latin for "No one provokes me with impunity").

The Order's primary emblem is the thistle, the national flower of Scotland. Royal Coat of Arms of the United Kingdom for use in Scotland
