He crossed the Alps and declared himself the king of Italy. He
was forced to return to Germany when the other German princes
began a series of revolts.
Otto in "great anger" captured Rome again, for the fourth time,
after the populace revolted from Pope John XIII, Ottos choice
for pontiff. There was no forgiveness for those whom he
considered oath breakers and traitors. The gallows, the sword,
blinding and mutiliating knife was the lot of the city.
The pagan Magyars were crushed by Otto on the Lech River. Otto
carried the Sacred Lance into the battle. The Magyars were
slaughtered to the man, with the exception of seven men, who
were sent home to tell their countrymen of their defeat. Otto's
stopping of the advance of the Magyars has been compared to
Charles Martel's stopping of the Moors at Poitier in 732 as a
major turning point in European, and Christian, history.
Otto recaptured Rome and deposed Pope John XII after the latter
revolted from Otto's rule of Rome and of Italy.
Otto again marched on and captured Rome as the Romans elected
Pope Benedict V against his wishes.
After the death of his wife Edgitha, he learned to read and
write.
A series of revolts against him broke out amongst his nobles
simultaneously, partly because, unlike his father, Otto was not
satisfied in being king in name only.
His elder bastard brother Thankmar took his younger legitimate
brother Henry as hostage during Thankmar's rebellion against
Otto's authority.
Otto carried into battle against his foes a victory-bringing
talisman: the Sacred Lance, the Dominica Hasta, containing one
of the nails that had pierced the hands and feet of Jesus. It
was said the Emperor Constantine had carried the Holy Lance
against Maxentius, which ended in the triumph of Christianity
over Roman paganism. Ottos' father Henry the Fowler had
purchased the Lance from Rudolf, the king of the Burgundians.
He sent an embassy to Emperor Nicephorus Phocas in
Constantinople to sue on behalf of his son for the hand of one
of the daughters of the deceased Emperor Romanus II. The
embassy was not successful nor friendly.
