So, how did Humpty come to be known as an egg?
Interestingly, the first appearance of an egg-shaped Humpty was in Lewis Carroll’s ‘Through the Looking Glass.’
Since then, the egg characterization has stuck.
But this leads to another question, what was Humpty before he was known as an egg?

It’s been proposed that the nursery rhyme tells the story of King Richard III and his defeat at the Battle of Bosworth Field in 1485, reports the Mirror.
History Defined elaborates on this, explaining that the king was recorded to have fallen, with his soldiers and men being unable to win the day.
