Maximinus II (Daia) in Wikipedia
Gaius Valerius Galerius Maximinus (c. 20 November 270 – July
or August 313), commonly known as Maximinus Daia or
Maximinus II, was Roman Emperor from 308 to 313. He was born
of peasant stock to the half sister of the emperor Galerius
near their family lands around Felix Romuliana; a rural area
now in the Danubian region of Moesia.
He rose to high distinction after he had joined the army,
and in 305 he was adopted by his maternal uncle Galerius and
raised to the rank of caesar, with the government of Syria
and Egypt. In 308, after the elevation of Licinius to
Augustus, Maximinus and Constantine were declared filii
Augustorum ("sons of the Augusti"), but Maximinus probably
started styling himself after Augustus during a campaign
against the Sassanids in 310. On the death of Galerius, in
311, Maximinus divided the Eastern Empire between Licinius
and himself. When Licinius and Constantine began to make
common cause with one another, Maximinus entered into a
secret alliance with the usurper Caesar Maxentius, who
controlled Italy. He came to an open rupture with Licinius
in 313, he summoned an army of 70,000 men, but still
sustained a crushing defeat at the Battle of Tzirallum, in
the neighbourhood of Heraclea Pontica, on the April 30, and
fled, first to Nicomedia and afterwards to Tarsus, where he
died the following August. His death was variously ascribed
"to despair, to poison, and to the divine justice".
Maximinus has a bad name in Christian annals, as having
renewed persecution after the publication of the toleration
edict of Galerius (see Edict of Toleration by Galerius).
Eusebius of Caesarea, for example, writes that Maximinus
conceived an "insane passion" for a Christian girl of
Alexandria, who was of noble birth noted for her wealth,
education, and virginity – Saint Catherine of Alexandria.
When the girl refused his advances, he exiled her and seized
all of her wealth and assets.
