Chapter One: In the Shadow of Giants (569-576)
The days following the death of the Emperor Justinian I were difficult ones for the Emperors in Constantinople. Italia and North Africa had been reclaimed for the Empire, but at an immense cost in both men and money. Outposts as far-flung as Hispania had Roman garrisons while, in Hellas, barbarians from the north pressed the Empire’s borders, threatening both Constantinople and Rome with the humiliation and devastation of sacking. The Empire itself was terribly weakened, as well, by the plague of Justinian, which had robbed the Empire of nearly a third of its population in the 540s. The only saving grace of this plague was that it had spread to Sassanian Persia, briefly granting the Empire respite from the specter of invasion from the east. Nevertheless, with enemies on all sides and a weakened interior, the Roman Empire appeared to be on the brink of catastrophe, just waiting for a spectacular 6th century collapse to mirror Rome’s sack a century before.
The Emperor at the time, Justin II, did little to inspire confidence in the Imperial citizens. A staunch Roman, Justin considered himself to be above diplomacy and treating with the myriad of enemies at Rome’s gates. For his dazzling predecessor, with a professional army and brilliant generals, such a method was acceptable, but Justin lacked the former; the army had been underpaid for years, and following the two-decade struggle in Italia and the plague, was spread far too thinly to form such powerful forces as had been commanded by Belisarius and Narses in days past. The Emperor, however, did have an effective general in the person of Tiberius Constantine, a Thracian-born man who, through his connection with the Patriarch of Constantinople Eutychius, had met and befriended the Emperor. Tiberius, while not a commander on par with Belisarius from the previous generation, was nevertheless an astute general and capable diplomat.
Tiberius’s abilities were needed in 569, a mere four years after the death of Justinian, when the Emperor decided to cease paying tribute the Avars and Lombards, two groups which lived on the northern border of Roman Hellas and Italia. This refusal sparked retaliatory invasions by both groups, the Avars in Hellas and the Lombards in Italia. With Constantinople potentially threatened, Justin granted Tiberius the title of Magister utriusque Militiae, the Master of Soldiers, on top of his position as Comes Excubitorum, or the commander of the Imperial Guards. Setting out to deal with the Avars, Tiberius managed to stop them from burning their way to Constantinople with the promise of land on the southern side of the Danube and Imperial protection, with only the demand of hostages of the Avar chiefs to be kept in Constantinople as hostages. The Avars accepted this deal, and for a time, carved out a semi-Roman state on either side of the Danube [1].
Refusing to learn from his mistakes, or possibly attempting to stem the endemic flow of gold and silver out of the Imperial treasury, Justin again refused to pay tribute in 572, this time to the Sassanian Persians. Their reaction was more severe, crossing the border with an army under their Shahanshah Khosrau I. An Imperial force under Marcian, a cousin of Justin’s, managed to defeat the Persians at the Battle of Sagathon, but his efforts to rapidly eliminate the Persian threat were undone when he was accused of attempting to usurp the throne from his cousin. Utterly convinced of the charges, Justin summoned Marcian to Constantinople. The loss of their leader disrupted the Imperial army and caused them to abandon the siege of Nisibis. The way now clear, Khosrau surged forward and, after a four-month siege, captured the Roman fort city of Dara.
It is hard not to blame the fiasco in the East on Justin. Not only had his refusal to pay of the Persians ended a peace treaty that had, theoretically, guaranteed forty more years of peace between the two powers, but he had also attempted to assassinate the King of the Ghassanids al-Mundhir III the very same year, robbing the Empire of a valuable ally on the Sassanian border, and he had eliminated any momentum Marcian’s army had gained. The fall of Dara reportedly caused Justin to slip into madness. In his moments of lucidity, Justin authorized the raising of Tiberius, his trusted general, to the rank of Caesar, and adopted him as a son. Tiberius, thus empowered, took it upon himself to correct the situation in the East.
Tiberius’s expedition East was at the head of an army composed of men from Hellas, including a unit of Excubitores from Constantinople, as well as a contingent of Avar Symmachi [2]. With both Tiberius and Marcian, the same cousin of Justin’s who had been accused of scheming to usurp the throne, in command of the expedition, much of 573 was spent preparing for battle. In 574, the city of Nisibis, where Marcian had been two years before, was invested by the Imperial troops. Meanwhile, Tiberius had sent riders down to the Ghassanids with a letter of apology, marked by the Emperor’s seal, and a hefty sum of gold. More importantly, the letters offered a resumption of the alliance against the Persians. What exactly Tiberius promised is unknown; most believe it is assistance in battling the Lakhmids, the Sassanian’s client state in Arabia, although some have theorized that Tiberius promised the death of Justin himself.
Whatever the case, the Ghassanids renewed their offensive against the Lakhmids, sacking their capital of Hira a year later. Meanwhile, a five-month siege of Nisibis concluded in the Empire taking the city before marching out to meet a Persian force moving to intercept the expedition. The two armies shadowed one another for much of the later summer of 574, finally coming to blows in late August in a skirmish along the coast of the Tigris. Two weeks later, the Imperial Army received reinforcements from the Armenian Kingdom, inspiring Tiberius to force a battle with the Sassanians. Tiberius’s infantry engaged that of the Sassanian general, a man named Tamkhosrau, who managed to force back Tiberius’s forces. However, the Imperial cavalry, mixed with Alan horsemen, managed to rout the Sassanian cavalry, who had been weakened by the departure of Shahanshah Khosrau three days earlier with a third of the cavalry, not having expected a battle this late in the year. With the Persian cavalry routed, the Alans led a ferocious charge into the Persian right flank, rolling up their line and stopping the Persian advance. Meanwhile, Tiberius managed to rally his forces and force the Sassanian army to retreat.
Victory at Bezabde won Tiberius the necessary space to make demands of the Sassanians. A five-year truce was agreed to, with Imperial payments to the Sassanians ended and the fortress of Nisibis returned to Persian hands. It was a continuation of the pre-war status quo, and it bought the Empire some breathing room to deal with the mounting issues it was facing. The mobilization of Tiberius’s army, while ultimately effective, had been a drain on the treasury that cut deeply into the Imperial books, even with the cessation of payments to both the Avars and Persians.
When Tiberius returned to Constantinople in 575, it was to the joy of much of the city. He had managed to end the humiliating tribute payed to Rome’s enemies and beaten back a threatening Persian army. The Emperor, however, was less happy with Tiberius’s return. The same jealousy that had led to his recall of Marcian had awoken in him, and the close work Tiberius and Marcian had dome together only furthered his fears [3]. The paranoia of Justin, once awakened, showed him threats everywhere: senators, noblemen, even his own guards were in Tiberius’s pocket. Regardless of whether or not his life legitimately was in danger, Justin felt threatened and, in 576, he made a decision that shocked the Roman world. In one of his final moments of lucidity, he decided to retire from the position of Emperor and pass it to his adoptive son, Tiberius. Justin dutifully retired to a monastery and Tiberius was crowned Emperor Tiberius II Constantine.
