Alexander (L. Domitius Alexander) 308 A.D. - 309 A.D.

Licinius then lost a second battle at Chrysopolis. After the intervention of his wife Constantia, half-sister of Constantine, Licinius surrendered and was interned at Thessalonica, while Martinian was put under house arrest in Cappadocia. However, they were both then executed, probably in the spring of 325.
