the rest being possessed by the Greek emperor, with whom Charles was
in league. About this time Pascal I. occupied the pontificate, and
the priests of the churches of Rome, from being near to the pope, and
attending the elections of the pontiff, began to dignify their own power
with a title, by calling themselves cardinals, and arrogated so great
authority, that having excluded the people of Rome from the election
of pontiff, the appointment of a new pope was scarcely ever made except
from one of their own number: thus on the death of Pascal, the cardinal
of St. Sabina was created pope by the title of Eugenius II. Italy having
come into the hands of the French, a change of form and order took
place, the popes acquiring greater temporal power, and the new
authorities adopting the titles of count and marquis, as that of duke
had been introduced by Longinus, exarch of Ravenna. After the deaths of
some pontiffs, Osporco, a Roman, succeeded to the papacy; but on account
of his unseemly appellation, he took the name of Sergius, and this was
the origin of that change of names which the popes adopt upon their
election to the pontificate.

In the meantime, the Emperor Charles died and was succeeded by Lewis
(the Pious), after whose death so many disputes arose among his sons,
that at the time of his grandchildren, the house of France lost the
empire, which then came to the Germans; the first German emperor being
called Arnolfus. Nor did the Carlovingian family lose the empire only;
their discords also occasioned them the loss of Italy; for the Lombards,
gathering strength, offended the pope and the Romans, and Arnolfo, not
knowing where to seek relief, was compelled to create Berengarius, duke
of Fruili, king of Italy. These events induced the Huns, who occupied
Pannonia, to assail Italy; but, in an engagement with Berengarius, they
were compelled to return to Pannonia, which had from them been named
Hungary.
