Warriors seem to have been present in the earliest pre-state societies. Along with hunting, war was considered to be a definitive male activity. No matter the pretext for combat, it seemed to have been a rite of passage for a boy to become a man. Warriors took upon costumes and equipment that seemed to have a symbolic significance; combat itself would be preceded by ritual or sacrifice. Men of fighting age often lived apart in order to encourage bonding, and would ritualise combat in order to demonstrate individual prowess among one another. Most of the basic weapons used by warriors appeared before the rise of most hierarchical systems. Bows and arrows, clubs, spears, and other edged weapons were in widespread use. However with the new findings of metallurgy, the aforementioned weapons had grown in effectiveness.
