Maximin (Galerius Valerius Maximinus), d. 313, Roman emperor (308–13); kinsman of Galerius. He is called Maximin Daia. He was made caesar in 305 and in 308 proclaimed himself augustus in opposition to Emperor Licinius . After the death of Galerius (310), Maximin exercised considerable power. He persecuted the Christians and tried to revive paganism. He later allied himself with Maxentius against Licinius and Constantine ( Constantine I ); Maxentius was crushed by Constantine, and Maximin was defeated by Licinius. A last-minute effort to win the Christians by an edict of toleration did not help him. He died a fugitive.
