  • On the 6th of November 355, a young man named Flavius Claudius Julianus stood before Emperor Constantius II in Mediolanum and received the title of Caesar of the West. He was only twenty-four years old and had spent most of his life under house arrest after his father was executed during the purges following Constantine's death in 337. The emperor gave him a small retinue and sent him to Gaul with instructions to remain a figurehead while experienced prefects managed real power. Julian quickly proved himself more than a puppet when Germanic tribes began raiding across the Rhine frontier. In 356 he led an army to Colonia Agrippina, now Cologne, recovering towns that had fallen into Frankish hands. His forces wintered near Senon, close to Verdun, where a tactical error left him virtually trapped for months by a Frankish siege until General Marcellus lifted the blockade. Relations between Julian and Marcellus deteriorated rapidly, leading to Marcellus's replacement by Severus as magister equitum.

    The following year brought a coordinated Roman operation against Alamanni forces. King Chnodomarius commanded a confederation of Alamanni troops that attacked Julian and Severus at Argentoratum, modern Strasbourg. Roman soldiers numbered fewer than their opponents, yet they achieved overwhelming victory. During the battle, six hundred horsemen on the right wing deserted, but the terrain favored the Romans who routed the enemy and drove them into the river. Chnodomarius was captured and later sent to Mediolanum. Ammianus Marcellinus, who fought in the battle, described Julian commanding events on the field and rejecting his soldiers' acclamation to make him Augustus. He rewarded their valor instead of accepting their offer of imperial power.

    In February 360, Constantius II ordered more than half of Julian's Gallic troops to join his eastern army. The order bypassed Julian entirely and went directly to military commanders. Troops of the Petulantes refused to leave Gaul and sparked an insurrection. Officers distributed anonymous tracts expressing complaints against Constantius while fearing for Julian's fate. Florentius, the praetorian prefect who usually stayed close to Julian, organized supplies in Vienne and avoided the conflict. The troops proclaimed Julian Augustus in Paris, forcing him onto a path toward civil war. He led campaigns against Attuarian Franks from June to August 360 and began openly using the title Augustus by November, issuing coins with or without Constantius's name.

    By spring 361, Julian marched his army into Alamanni territory and captured King Vadomarius, claiming the king had conspired with Constantius. He divided forces across Raetia, northern Italy, and down the Danube on boats. His general Nevitta secured the pass of Succi into Thrace, placing Julian well outside his comfort zone. In June, forces loyal to Constantius captured Aquileia on the north Adriatic coast, threatening to cut Julian off from his main force. Julian besieged the city with 23,000 men while waiting in Naissus, writing letters to Greek cities justifying his actions. Only one letter to Athens survives intact. Civil war ended when Constantius died on the 3rd of November 361, allegedly naming Julian as his successor to prevent further bloodshed.

  • Julian's first campaign in 356 took him to the Rhine where he engaged Frankish inhabitants and recovered Colonia Agrippina, now Cologne. After securing success, he withdrew for winter to Gaul, distributing forces to protect various towns. He chose Senon near Verdun as a base, but this proved a tactical error when a large Frankish contingent besieged the town. Julian remained virtually captive there for several months until General Marcellus lifted the siege. Relations between Julian and Marcellus deteriorated quickly, leading to Marcellus's replacement by Severus.

    The following year brought coordinated Roman operations against Germanic peoples who had spilled across the river onto the west bank. Magister peditum Barbatio advanced from Milan with 25,000 soldiers to Augst near the Rhine bend, then moved north. Julian with 13,000 troops would move east from Durocortorum, modern Rheims. While Julian was in transit, Laeti attacked Lugdunum, Lyon, delaying his movement. This left Barbatio unsupported deep in Alamanni territory, forcing him to withdraw retracing his steps. The coordinated operation collapsed without either commander achieving their objectives.

    King Chnodomarius led a confederation of Alamanni forces against Julian and Severus at Argentoratum. Romans were heavily outnumbered yet achieved overwhelming victory through terrain advantages. During battle heat, six hundred horsemen on the right wing deserted, yet the enemy was routed and driven into the river. King Chnodomarius was captured and sent to Mediolanum. Ammianus Marcellinus, participant in the battle, portrayed Julian commanding events on the battlefield and described how soldiers acclaimed him as Augustus, an acclamation he rejected while rebuking them. He later rewarded soldiers for their valor rather than accepting imperial power.

    Rather than chase routed enemies across the Rhine, Julian followed the river northward, the same route he had taken the previous year returning to Gaul. At Moguntiacum, Mainz, he crossed the Rhine in an expedition penetrating deep into what is now Germany. Three local kingdoms submitted to Roman authority, demonstrating that Rome remained present and active in the area. On his return journey to winter quarters in Paris, he dealt with Franks who controlled abandoned forts along the Meuse river. In 358, Julian gained victories over Salian Franks on the Lower Rhine, settling them in Toxandria within the empire north of modern Tongeren. Chamavi tribes were expelled back to Hamaland.

    At the end of 357, Julian prevented a tax increase by Gallic praetorian prefect Florentius and personally took charge of Belgica Secunda province. This marked his first experience with civil administration, where liberal education from Greece influenced his views. The role properly belonged to the praetorian prefect, yet Julian clashed repeatedly with Florentius over administration. His priority as Caesar and nominal ranking commander was driving out barbarians breaching the Rhine frontier. He sought civilian support necessary for operations while showing Germanic army benefits of Imperial rule. Rebuilding stable conditions in devastated cities and countryside became essential for winning popular support.

  • On the 5th of March 363, despite omens against the campaign, Julian departed Antioch with approximately 65,000 to 83,000 men heading north toward the Euphrates. Embassies from small powers offered assistance en route, none accepted though he ordered Armenian King Arsaces to muster an army awaiting instructions. Crossing near Hierapolis, he moved eastward to Carrhae giving impression that chosen route down Tigris was intended. A force of 30,000 soldiers under Procopius and Sebastianus marched further east to devastate Media alongside Armenian forces where main Persian forces soon directed themselves.

    Julian's strategy lay elsewhere. He had a fleet built of over 1,000 ships at Samosata to supply his army marching down Euphrates plus 50 pontoon ships facilitating river crossings. Procopius and Armenians would march down Tigris meeting Julian near Ctesiphon. Ultimate aim seemed regime change replacing king Shapur II with brother Hormisdas. Feigning march further eastward, Julian's army turned south to Circesium at confluence of Abora and Euphrates arriving beginning April. Passing Dura on the 6th of April, army made good progress bypassing towns after negotiations or besieging those opposing him. End of April saw Romans capture Pirisabora fortress guarding canal approach from Euphrates to Ctesiphon on Tigris.

    By mid-May, army reached vicinity of heavily fortified Persian capital Ctesiphon where Julian partially unloaded fleet having troops ferried across Tigris by night. Romans gained tactical victory before city gates driving Persians back into city. However, Persian capital not taken because master-general Victor ordered soldiers not entering open gates pursuing defeated Persians fearing encirclement within walls. Main Persian army remained large approaching while Romans lacked clear strategic objective. In council following, Julian's generals persuaded him not mounting siege against city given impregnability defenses and fact that Shapur would soon arrive with large force.

    Julian set off east into Persian interior ordering destruction of fleet proving hasty decision since they stood wrong side of Tigris without clear retreat means. Persians began harassing them from distance burning any food in Roman path. Julian had not brought adequate siege equipment doing nothing when finding Persians flooded area behind forcing withdrawal. Second council of war on the 16th of June 363 decided best course leading army back safety Roman borders northward to Corduene rather than through Mesopotamia.

    During withdrawal, Julian's forces suffered several attacks from Sassanid forces. One engagement on the 26th of June 363 at indecisive Battle of Samarra near Maranga in Mesopotamia saw Julian wounded when Sassanid army raided column. Pursuing retreating enemy choosing speed over caution taking only sword leaving coat mail behind. Received wound from spear reportedly piercing lower lobe liver and intestines. Wound not immediately deadly treated by personal physician Oribasius of Pergamum making every attempt treating including irrigation dark wine and procedure known as gastrorrhaphy suturing damaged intestine. Despite efforts third day major hemorrhage occurred emperor died during night.

  • After gaining purple, Julian started religious reformation empire intended restoring lost strength Roman state supporting restoration Hellenistic polytheism state religion. Laws tended targeting wealthy educated Christians aiming destroying Christianity but driving religion out governing classes empire much Chinese Buddhism driven back lower classes revived Confucian mandarinate 13th century China. Restored pagan temples confiscated since Constantine time simply appropriated wealthy citizens repealing stipends Constantine awarded Christian bishops removing privileges including right consulted appointments acting private courts reversing favors previously given Christians.

    On the 4th of February 362, Julian promulgated edict guaranteeing freedom religion proclaiming all religions equal before law Roman Empire returning original religious eclecticism according which Roman state imposing any religion provinces.
