This is a dual biography of the emperors Marcus Antonius Gordianus (‘Gordian III’, reigned 238-244) and Marcus Julius Philippus Augustus (‘Philip the Arab’, reigned 244-249), focusing mainly on the political and military events during this crucial stage of the ‘Third Century Crisis’. The tumultuous 'Year of the Six Emperors' saw Gordian raised to the purple at just thirteen years of age, becoming the youngest emperor in the Empire’s history at a time when the borders were threatened by the powerful Sassanid Persians and the Goths, among others. Gordian died on a campaign against the Persians, either in battle or possibly murdered by his own men. Philip, succeeded Gordian, made peace with Shapur I and returned to Italy. His reign encompassed the spectacular celebration of Rome’s millennium in 248 but the wars in the Balkans and East together with crippling taxation led to mutinies and rebellions. Philip and his brother had until then fought successfully against the Persians and others but this did not save Philip, who was killed by a usurper’s forces at the Battle of Verona in 249. He had been Rome’s first Christian emperor and the author considers why it was fifty years before she had another.

When Philip the Arab came to the Roman throne in the third century AD, the Empire, in the words of the sophist Nicarogas, was tossing as in a great storm or earthquake, and floundering like a ship being carried off to the ends of the Earth. The rise of Philip, an Arab of a peripheral tribe in Arabia, to the throne of the Ceasars in the millennium of the birth of the Roman Empire, was a momentous event in Islamic history. A man of intelligence and immense determination, he brought the ship under control and secured her at anchor.

“An unusual history of an unusual soldier of Rome who rose to Emperor . . . an engaging history of a fascinating subject—Very Highly Recommended.” —Firetrench This is the only fully illustrated military life of the Emperor Publius Licinius Egnatius Gallienus (253-268). Considered the most blatantly military man of all of the soldier emperors of the third century, Gallienus is the emperor in Harry Sidebottom’s bestselling Warrior of Rome novels. Gallienus faced more simultaneous usurpations and foreign invasions than any other emperor, but somehow he managed to survive. Dr. Ilkka Syvanne explains how this was possible. It was largely thanks to the untiring efforts of Gallienus that the Roman Empire survived for another 1,200 years. Gallienus was a notorious libertarian, womanizer, and cross-dresser, but he was also a fearless warrior, duelist and general all at the same time. This monograph explains why he was loved by the soldiers, yet so intensely hated by some officers that they killed him in a conspiracy. The year 2018 was the 1,800th anniversary of Gallienus’ date of birth and the 1,750th anniversary of his date of death. The Reign of Gallienus celebrates the life and times of this great man. “A beautiful book that investigates the life and works of an emperor undervalued by the ‘general public’ but who deserves to be known for his military and historical legacy.” —Old Barbed Wire Blog

An in-depth military history of the emperors Lucius Domitius Aurelianus and Marcus Aurelius Probus. This is a narrative military history of the emperors Lucius Domitius Aurelianus (“Aurelian,” reigned 270-275) and Marcus Aurelius Probus (276-282) that also includes the other reigns between the years 268 and 285. It shows how these two remarkable emperors were chiefly responsible for the Empire surviving and emerging largely intact from a period of intense crisis. It was Aurelian who first united the breakaway regions, including Zenobia’s Palmyra, and it was Probus who then secured his achievements. The reigns of Aurelian and Probus have been subjected to many studies, but none of these have approached the extant material purely from the point of view of military analysis. Most importantly, the previous historians have not exploited the analytical opportunities provided by the military treatises that describe the strategy and tactics of the period Roman army. It is thanks to this new methodology that Ilkka Syvänne has been able to reconstruct the military campaigns of these two soldier emperors and their other contemporaries in far greater detail than has been possible before. Praise for Aurelian and Probus “A critical work... Aurelian and Probus is a very good look at a very confusing period in Roman history.” —The NYMAS Review

This pioneering study examines a pivotal period in the history of Europe and the Near East. Spanning the ancient and medieval worlds, it investigates the shared ideal of sacred kingship that emerged in the late Roman and Persian empires. Bridging the traditional divide between classical and Iranian history, this book brings to life the dazzling courts of two global powers that deeply affected the cultures of medieval Europe, Byzantium, Islam, South Asia, and China.

This ambitious series gives the reader a comprehensive narrative of late Roman military history from 284-641. Each volume (5 are planned) gives a detailed account of the changes in organization, equipment, strategy and tactics among both the Roman forces and her enemies in the relevant period, while also giving a detailed but accessible account of the campaigns and battles. Volume I covers the period 284-361, starting with recovery from the 'third-century crisis' and the formation of the Tetrarchy. Constantine's civil wars and stabilization.are also major themes, with the pattern repeated under his sons. Constantius II's wars against the usurper Magnentius, the Danubian tribes and the Sassanid Persians illustrate the serious combination of internal and external threats the Empire faced at this time. The author discusses these and the many other dramatic military events in their full context and puts forward some interesting conclusions on strategic and tactical developments. He argues, for example, that the Roman shift from infantry to cavalry as the dominant arm occurred considerably earlier than usually accepted. Anyone with an interest in the military history of this period will find it both informative and thought-provoking.

This biography of the Roman Emperor Caracalla challenges his tyrannical reputation with a revealing narrative of his social reforms and military campaigns. Caracallahas one of the worst reputations of any Roman Emperor. Many ancient historians were very hostile, and the 18th century English historian Edward Gibbon even dubbed him the common enemy of mankind. Yet his reign was considered by at least one Roman author to be the apogee of the Roman Empire. He was guilty of many murders and massacres—including that of his own brother, ex-wife and daughter. Yet he instituted the Antonine Constitution, granting citizenship to all free men in the Empire. He was also popular with the army, improving their pay and cultivating the image of sharing their hardships. Historian Ilkka Syvanne explains how the biased ancient sources in combination with the stern looking statues of the emperor have created a distorted image of the man. He then reconstructs a chronology of Caracalla’s reign, focusing on his military campaigns and reforms, to offer a balanced view of his legacy. Caracalla offers the first complete overview of the policies, events and conflicts he oversaw and explains how and why these contributed to the military crisis of the third century.
