Gallienus, born Publius Licinius Egnatius Gallienus around 218 AD, was a Roman emperor who co-ruled with his father Valerian from 253 to 260 AD, and then ruled alone until 268 AD12. His reign was marked by the Crisis of the Third Century, a period of severe instability and fragmentation within the Roman Empire. Despite facing numerous invasions and internal revolts, Gallienus implemented significant military reforms, including the creation of a mobile cavalry reserve. He also promoted a cultural renaissance in Rome, supporting intellectuals and artists. Gallienus was ultimately assassinated in 268 AD during a siege in Milan.
