Maxentius and Maximian reigned in the West as "augusti" co-operating with Constantine as "caesar" until the Imperial conference at Carnutum in November 308, whereat Constantine confirmed as "caesar", Maximian deposed, and Licinius appointed "augustus" in his place. Maxentius continued to hold power as a rival Emperor until 312; his father Maximian (the first Emperor to be restored) committed suicide after an attempt to don the purple a third time in 310. "Diocletian"'s wife Prisca bore him a daughter Galeria Valeria, who married "Galerius" (whom Diocletian had adopted and appointed "caesar" on March 1, 293). Galerius's sister gave birth to a son, "Maximinus Daia", and Galerius's daughter by his first wife, Valeria Maximilla, married "Maxentius", son of "Maximian" by his wife Eutropia; Eutropia's first marriage (to Afranius Hannibalianus) had produced a daughter, Theodora, who became the second wife of "Constantius Chlorus" ("the Pale") in 289 (adopted by Maximian on March 1, 293). Constantius's marriage to Theodora produced a daughter, Constantia, who married "Licinius"; his first marriage to Helena produced a son, "Constantine", whose second wife was Fausta, sister of Maxentius and daughter of Maximian. To summarise:    The death of Galerius in May 311 and Constantine's spectacular victory over Maxentius at the Milvian Bridge on October 28, 312, left only three Emperors: in the East, Maximinus Daia and Licinius; in the West, Constantine. Licinius defeated Maximinus Daia in April 313 at Tarsus, and the latter committed suicide shortly thereafter, leaving Licinius and Constantine the only Emperors; they governed the Empire along the usual lines of East and West, respectively, discarded the defunct Tetrarchical system, warred against one another in 316 – 317, and again in 324 – 325. The execution of Licinius in spring 325 left Constantine the first sole Emperor since Diocletian made Maximian his co-Emperor in 286. The Constantinian dynasty properly began with Constantius "Chlorus" ("caesar", 293, "augustus", 305), an experienced Illyrian soldier and general; the Constantiniani were originally another family of "Barracks Emperors".
