Galerius Valerius Maximianus, Caesar 293 - 305, Augustus 305 - 311

Galerius was appointed Caesar of the east under Diocletian in 293, and his appointment completed the tetrachy. On the abdications of Diocletian and Maximian in 305, he became the eastern Augustus. Severus II and Maximinus II were appointed as Caesars in the west and east respectively. However, on the death of the western Augustus, Constantius I, his son, the popular Constantine I was proclaimed Augustus by the troops in York.  Galerius was enraged by this usurpation and elevated Severus to Augustus, but permitted Constantine to hold the rank of Caesar. Constantine wisely agreed to this. More trouble was to follow (see under Maximian). In 311, Galerius contracted a disfiguring disease from which he never recovered.
