of the necessities of this intergroup struggle, or war. As we have
already seen, the groups that were best organized, that had the most
competent leadership, would stand the best chance of surviving.
Consequently the war leader or chief soon came, through habit, to be
looked upon as the head of the group in all matters. Moreover, the
exigencies and stresses of war frequently necessitated giving the war
chief supreme authority in times of danger, and from this, without
doubt, arose despotism in all of its forms. The most primitive tribes
are republican or democratic in their form of government, but it has
been found that despotic forms of government rapidly take the place of
the primitive democratic type, where a people are continually at war
with other peoples.

(3) A third result of war in primitive times was the creation of social
classes. After a certain stage was reached groups tried not so much to
exterminate one another as to conquer and absorb one another. This was,
of course, after agriculture had been developed and slave labor had
reached a considerable value. Under such circumstances a conquered group
would be incorporated by the conquerors as a slave or subject class.
Later, this enslaved class may have become partially free as compared
with some more recently subjugated or enslaved classes, and several
classes in this way could emerge in a group through war or conquest.
Moreover, the presence of these alien and subject elements in a group
necessitated a stronger and more centralized government to keep them in
control, and this was again one way in which war favored a development
of despotic governments. Later, of course, economic conditions gave rise
to classes, and to certain struggles between the classes composing a
people.
