Id is a concept of Sigmund Freud, founder of psychoanalysis. The id is the unconscious drives and psychic energies of humans as biological organisms.
Id is untouched by culture and social learning and encompasses all that is primitive, natural and pre-civilized in human passions and energies.
Freud seems to have assumed that the human struggle to achieve self consciousness against the ungoverned and unconstrained passions of the id, remained deeply buried in the unconscious minds of all human beings.

Colonial Basis to Freuds Ego, Id, Superego - Rachael Vaughan
Introduction: When I first read Freuds metaphorical mapping of the psyche into regions called id, ego and superego, it made me uneasy. There seemed to be something sadly flawed about his apparent conception of the instinctual realm as profoundly base, dangerous and untrustworthy.
I was equally unable to approve of the ego as conceptualized by Freud: this arrogant horseman astride the id, using its energy to control the beast, transforming the ids will into action as though it were its own (Freud 1923, p. 636). It was the id as described by Freud that gave me the most difficulty. I was concerned for the id. It seemed as though there was some projection going on, and that the id was getting the brunt of it.
