I can think of the simple structure he's talking about, it's best documented in Zoroastrianism aka the struggle between good and evil. The conquerors were good and the defeated savages were evil, and the conquerors often faced unsurmountable odds. Origin stories of civilization and religion follow this structure quite often.
