Humpty Dumpty sat on a wall.
Humpty Dumpty had a great fall.
All the king's horses and all the king's men
Couldn't put Humpty together again.
It’s an old nursery rhyme that was originally posed as a riddle, and the answer was that Humpty Dumpty was an egg.
If it has any meaning beyond that, it’s yours to make. I personally like it being a story of a king that spent all his time and efforts on building an army while ignoring everything else, just to have some other unforeseen thing topple his rule in a way that no army could repair.
The Humpty Dumpty name pre-dates the image of an egg character that was created by Lewis Carroll's Through The Looking Glass.
A popular theory says the rhyme may have originated by the story of a large cannon used by the Royalists in the English Civil War.
Humpty Dumpty was a term, probably with derogatory inferences, that was applied to large or oversized persons or objects.
The Humpty cannon allegedly fell off the wall that it was stationed upon, thanks to Parliamentary forces undermining it, and was severely damaged.
The falling cannon story became a metaphor for the Royalist leader, King Charles I, who was believed to be large sized himself. He lost the Civil war, and his head, therefore he proverbially "had a great fall"
