Events

By place

Roman Empire

• Winter: Emperor Galerius wins his second victory over the Sarmatians.
• Galerius sends Valerius Severus with the army of northern Italy, to suppress the rebellion in Rome. However, faced with their former emperor Maximian, the soldiers desert him, and Severus flees to Ravenna. Maximian besieges Severus in Ravenna, who then surrenders. Maxentius makes Severus a hostage, in an attempt to keep Galerius at bay.
• Summer: Anticipating an offensive by Galerius, Maximian travels to Gaul to make an alliance with Constantine I.
• Late summer or autumn: Galerius invades Italy but Maxentius remains behind the walls of Rome. Galerius finds he cannot besiege the city, and the image of an emperor making efforts against Rome hurts Galerius' image among the troops. The fact that Maxentius is his son-in-law does not help, and Maxentius makes an effort to bribe Galerius' troops. Galerius unsuccessfully attempts to negotiate, and recognizing Maxentius' attempts at bribery and the danger of being trapped in Italy by Maximian and Constantine, Galerius chooses to withdraw from Italy. To satiate his troops during the withdrawal, he pillages the Italian countryside. Meanwhile, Maxentius executes Severus.
• December: Constantine marries Maximian's daughter Fausta, and is promoted to Augustus by Maximian.
• Near the end of the year, Galerius gives his wife (Diocletian's daughter) Galeria Valeria the title of Augusta.
