The short man syndrom.
The Napoleon complex is a colloquial term describing an alleged
type of inferiority complex which is said to affect some people who
are physically short. The term is also used more generally to
describe people who are driven by a perceived handicap to
overcompensate in other aspects of their lives. This term is also
known as Napoleon syndrome, Short Man syndrome, and Small Man
syndrome.
The Napoleon complex is named after French Emperor Napoleon
Bonaparte. The conventional wisdom is that Napoleon overcompensated
for his short height by seeking power, war and conquest.
