Most British orders of chivalry cover the entire United Kingdom, but the three most exalted ones each pertain to one constituent country only. The Order of St Patrick, which pertains to Ireland, is the most junior of these three in precedence and age. Its equivalent in England, the Most Noble Order of the Garter, is the oldest order of chivalry in the British Isles, dating from the mid fourteenth century. The Scottish equivalent is the Most Ancient and Most Noble Order of the Thistle, dating in its present form from 1687.
