frontier. He also planned to
meet the invaders on equal terms by training his warriors to fight on
horseback. He instituted tournaments and created an order of knighthood,
and is thus generally regarded as the founder of chivalry, that fairest
fruit of mediaeval times, which did so much to preserve honor and
tenderness and respect for womankind.[10]

When he felt all prepared, Henry deliberately defied and insulted the
Hungarians, and so provoked from them a combined national invasion,
which he met and completely overthrew in the battle of Merseburg (933).
A generation later the Huns felt themselves strong enough to try again;
but Henry's son, Otto the Great, repeated the chastisement. He then
formed a boundary colony or "East-mark" from which sprang Austria; and
this border kingdom was always able to keep the weakened Huns in check.

At the same time there was growing up in Russia a Slavic civilization,
which received Christianity[11] from the South as it had received
Teutonic dominion from the North, and so developed along very similar
lines to Western Europe. The Russian states served as a barrier against
later Asiatic hordes; and this, combined with the civilizing of the last
remnants of the Scandinavians in the North, and the fading of Saracenic
power in the South, left the tottering civilization of the West free
from further barbarian invasion. We shall find destruction threatened
again in later ages by Tartar and by Turk; but the intruders never reach
beyond the frontier. The Teutons and the half-Romanized ancients with
whom they had assimilated were left to work out their own problems. All
the ingredients, even to the last, the Northmen, had been poured into
the caldron. There remains to see what the intermingling has brought
forth.

FEUDAL EUROPE

We have here, then, somewhere about the middle of the tenth century, a
date which may be regarded as marking a distinctly new era. The
ceaseless work of social organization and improvement, which seems so
strong an instinct of the Aryan mind, had been recommenced again and
again from under repeated deluges of barbarism. To-day for nearly a
thousand years it has progressed uninterrupted, except by disturbances
from within; nor does it appear possible, with our present knowledge of
science and of the remoter corners of the globe, that our civilization
