and divide the spoil on a fixed scale. During a century of warfare this
alliance was faithfully adhered to and the confederates met with great
success. At the beginning of the sixteenth century, just before the
arrival of the Spaniards, the Aztec dominion reached across the
continent, from the Atlantic to the Pacific. There was thus included in
it territory thickly peopled by various races, themselves warlike, and
little inferior to the Aztecs in social organisation. What this
organisation was may be briefly indicated.

The government of the Aztecs, or Mexicans, was an elective monarchy, the
sovereign being, however, always chosen from the same family. His power
was almost absolute, the legislative power residing wholly with him,
though justice was administered through an administrative system which
differentiated the government from the despotisms of the East. Human
life was protected, except in the sense that human sacrifices were
common, the victims being often prisoners of war. Slavery was practised,
but strictly regulated. The Aztec code was, on the whole, stamped with
the severity of a rude people, relying on physical instead of moral
means for the correction of evil. Still, it evinces a profound respect
for the great principles of morality, and as clear a perception of those
principles as is to be found in the most cultivated nations. One
instance of their advanced position is striking; hospitals were
established in the principal cities, for the cure of the sick, and the
permanent refuge of the disabled soldier; and surgeons were placed over
them, "who were so far better than those in Europe," says an old
chronicler, "that they did not protract the cure, in order to increase
the pay."

In their religion, the Aztecs recognised a Supreme Creator and Lord of
