[4] Knights would be entitled to the post-nominal letters KM, and would wear a silver nine-pointed breast star with the image of Minerva at its centre, along with a "straw-coloured" sash worn across the chest from the right shoulder.

Once the King's proposal was made public, however, arguments within intellectual circles over who would be most deserving of the new order grew so heated that George ultimately dropped the idea,[4] though he briefly reconsidered it in 1789; on 6 February of that year, he revised the design of the order, with the breast star to have sixteen points, the motto to be the Latin for "Learning improves character" and with membership to include distinguished scientists.

[5] Following the Battle of Trafalgar in 1805, First Lord of the Admiralty Charles Middleton, 1st Baron Barham and William Pitt exchanged correspondence concerning the possible creation of an order of merit, though nothing came of the idea.

[6] Later, Queen Victoria, her courtiers, and politicians alike,[7] thought that a new order, based on the Prussian order Pour le Mérite, would make up for the insufficient recognition offered by the established honours system to achievement outside public service, in fields such as art, music, literature, industry and science.

[6] Victoria's husband, Albert, Prince Consort, took an interest in the matter; it was recorded in his diary that he met Sir Robert Peel on 16 January 1844 to discuss the "idea of institution of a civil Order of Merit" and, three days later, he conferred with the Queen on the subject.

[9] It was Victoria's son Edward VII who eventually founded the Order of Merit on 26 June 1902 (the date for which his coronation had been originally scheduled[10]) as a means to acknowledge "exceptionally meritorious service in Our Navy and Our Army, or who may have rendered exceptionally meritorious service towards the advancement of Art, Literature and Science".

Several individuals have refused admission into the Order of Merit, including Rudyard Kipling, A. E. Housman, and George Bernard Shaw.

Prince Philip, Duke of Edinburgh, remains the youngest person ever inducted into the Order, having been admitted by Queen Elizabeth II in 1968, when he was 47 years old.
