Equestria the nation has existed for more than 1000 years, having been founded at the end of the Eternal Winter by the original Mane Six (Clover the Clever, Smart Cookie, Commander Hurricaine, Private Pansy, Chancellor Puddinghead and Princess Platinum). The foundation of the nation was long enough before Luna's psychotic episode (now known as 'Nightmare Moon') that the Diarchs were considered something of a fixture of the national government.

Of course, the actual planet is likely far more ancient (by eight or more orders of magnitude).
