[1] Since the monarchy's abolition in 1973, it has been considered a dynastic order of the former Greek royal family.

[2] The order was founded in 1915 by King Constantine I in honor of his father, George I.

As the Order was restricted to officers and senior state officials, an additional Commemorative Medal of the Order of George I (Αναμνηστικόν μετάλλιον του Τάγματος Γεωργίου Α') was instituted in 1915 for NCOs and common soldiers, junior officials and ordinary citizens.

The obverse central disc was in red enamel, bearing the royal cypher of George I, two crossed gammas with a crown above and a "I" below, surrounded by a white enamel ring bearing the royal motto ΙΣΧΥΣ ΜΟΥ Η ΑΓΑΠΗ ΤΟΥ ΛΑΟΥ ("The Love of My People is My Strength").

The reverse central disc bears the years of George I's reign, 1863-1913.
