but a thousand years earlier it had lost control of the West because of
external violence and internal weakness. So great, however, was the
strength of the idea of an "empire," even in the West, that Charlemagne
about the year 800 temporarily united what are now France, Germany,
Italy, the Netherlands, and Belgium into what he persisted in styling
the "Roman Empire." Nearly two centuries later, Otto the Great, a
famous prince in Germany, gave other form to the idea, in the "Holy
Roman Empire" of which he became emperor. This form endured from 962 to
1806.

[Sidenote: The Holy Roman Empire; Its Mighty Claims in Theory and its
Slight Power in Practice]

In theory, the Holy Roman Empire claimed supremacy over all Christian
rulers and peoples of central and western Europe, and after the
extinction of the eastern empire in 1453 it could insist that it was
the sole secular heir to the ancient Roman tradition. But the greatness
of the theoretical claim of the Holy Roman Empire was matched only by
the insignificance of its practical acceptance. The feudal nobles of
western Europe had never recognized it, and the national monarchs,
though they might occasionally sport with its honors and titles, never
admitted any real dependence upon it of England, France, Portugal, or
Spain. In central Europe, it had to struggle against the anarchical
tendencies of feudalism, against the rise of powerful and jealous city-
states, and against a rival organization, the Catholic Church, which in
its temporal affairs was at least as clearly an heir to the Roman
tradition as was the Holy Roman Empire. From the eleventh to the
thirteenth century the conflict raged, with results important for all
concerned,--results which were thoroughly obvious in the year 1500.
