Humiliation (also called stultification) is the abasement of pride, which creates mortification or leads to a state of being humbled or reduced to lowliness or submission. It can be brought about through bullying, intimidation, physical or mental mistreatment or trickery, or by embarrassment if a person is revealed to have committed a socially or legally unacceptable act. Whereas humility can be sought alone as a means to de-emphasise the ego, humiliation must involve other person(s), though not necessarily directly or willingly.
