The order was instituted in 1799 by Sultan Selim III when he wished to reward Horatio Nelson, an Anglican Christian, for his victory at the Battle of the Nile.
The Order was then extended to reward further British military successes on land and sea against Napoleon's forces in Egypt and the Eastern Mediterranean in 1801.
[1] Nelson was so proud of his award that he appended it to his name in the Articles of Capitulation with Denmark after the Battle of Copenhagen on 9 April 1801 (news of which appending so pleased the Sultan that he added a ribbon and gold medal to Nelson's star).
However, the British Royal Warrant at the College of Arms allowing him to wear it is only dated 20 March 1802.
[1] Recipients (usually naval or army officers or representatives of Britain or France, highly present in the region during the Napoleonic Wars) were awarded a lozenge-shaped silver radiant star, embroidered in silver thread on an azure background with a star and crescent in the centre, and a red ribbon, to be worn with the crescent to the star's left.
