These robber chiefs had no right but might. They were outlaws, and
lived either in a country which had no government and laws, or in one
whose government was too weak to protect its people. They were no
worse, however, than the so-called feudal barons who came after them,
who oppressed the people even more, because they had on their side
whatever law and government existed in those days.

Now let us stop to consider how first there came to be kings. In the
early days of the human race and also in later days among barbarous
peoples, the land was very sparsely settled. The reason lay in the
chief occupations of the men. A small tribe might inhabit a great
stretch of territory through which they wandered to keep within reach
of plenty of game. As time went on, however, the population increased,
and, as agriculture took the place of hunting, and homes became more
lasting, tribes found themselves living in smaller and smaller tracts
of land, and hence nearer to their neighbors. In some cases, constant
fighting went on, just as Caesar tells us that two thousand years ago,
the Swiss and the Germans fought almost daily battles back and forth
across the Rhine. In other cases, the tribes found it better for all
concerned to make treaties of peace with their neighbors, and if they
did not exchange visits and mix on friendly terms, at least they did
not attack each other.

Finally, one day there would come to several tribes which had treaties
with each other a common danger, such as an invasion by some horde of
another race or nation. Common interest would drive them together for
mutual protection, and the chief of some one of them would be chosen
