Part 23: A Steady Hand
The decades that marked the later half of the reign of Yazdegerd I, following the trend established during Tiridates' tenure as Priest of Priests, were marked by peace abroad and growing prosperity at home. His pacifistic foreign policy kept thousands of lives and dirhams (the empire's currency) from being wasted in potentially unnecessary wars and also allowed international trade to flourish, which was extremely important since much of the Iranian economy depended on routes such as the Silk Road, which passed through the domains of the Hephthalites, who were by far the empire's greatest foreign adversary at the moment.
This isn't to say that it didn't irritate some of the more jingoistic factions of the nobility, who controlled most of the military and were always eager for more glory and lands to directly control in the name of their monarch. These people, perhaps best personified in the figure of Farrukhan Suren (1) (whose family, one of the Seven Great Houses, controlled Sakastan as their personal fiefdom before the arrival of the Hephthalites) were especially outraged by Yazdegerd's unwillingness to do so much as recapture Nishapur, arguing that the city, by remaining under outside control, served as a dagger pointed straight at the heart of the empire, an allegation that would later be proven right. Another decision that ruffled some feathers, but really just a few, was the recognition of Egypt as an independent kingdom through a treaty in 370 A.D. (2).
This isn't to say that the military was neglected, not at all. In the years following his return to power, the Shah ordered the construction of two fleets: a smaller one, based in the island of Hormoz, to protect the ports and trading vessels of the Persian Gulf from Arabian pirates who controlled the southern shores, and a much larger one, based in Haifa, to protect the Levantine ports from enemy blockades. The crews of this second fleet, however, were of questionable loyalty at first, considering that the cities they came from, while not outright rebelling against Iranian domination, chafed and grumbled, nostalgic of the glory days of the Palmyrene Empire.

Staying true to his reputation as a gray and boring ruler when compared to his more spectacular ancestors and descendants, Yazdegerd was content with doing little more than provinding a steady hand, rarely rocking the boat, if ever. His main priority was to leave a strong, stable and wealthy state for his successor to rule, and he ordered the construction of multiple infrastructure works such as irrigation canals (especially in Mesopotamia and Khuzestan, the most fertile regions of Iran), roads and bridges, leading to a steady increase in the degree of urbanization in the regions they were built, which would later help future Shahs in their attempts to centralize the state. While the Sasanian dynasty generally favored refurbishing and founding new cities, the Age of Division, and the economic slump that followed it, did much to slow or perhaps even halt that trend, which began to progess once more after stability was restored.
When it ccomes to building things, however, Yazdegerd is best remembered for two things: the Royal Road and the founding of the city of Peroz-Ardashir. The first project, as its name indicates, was a superbly maintained highway built in the mold of the homonymous one that was created by the Achamenid Shahanshah Darius the Great, who the Sasanians always sought to emulate. Starting from the city of Meshan, an important port in the Persian Gulf, the road followed the banks of the Tigris until it reached Ctesiphon, then following the Euphrates until Dura Europos. From there, it went westward into Syria, reaching Damascus and finally the port of Haifa.
Since its completion, the Royal Road quickly became the economic and logistical backbone of the Iranian empire, providing a path that could be traveled with great speed by both traders and armies alike, strengthening Ctesiphon's authority over the Levant. Not only that, it led to an immense amount of trade between Mesopotamia and the Mediterranean by creating an alternate path that, stretching from the Persian Gulf to Palestine, bypassed the Aksumite stranglehold over the Red Sea and allowing European markets to buy Indian and Chinese goods (such as spices and silk) at lower prices. Thus, it also caused a slight decline in Aksum and Egypt's revenues (the latter not by much) since they no longer controlled the only maritime route from the Far East to the West.
Sitting right on the middle of the path of this great highway, close to where the proud capital of the Palmyrene Empire once stood, the city of Peroz-Ardashir was founded. As stated in its very name ("Ardashir the Victorious"), it was, first and foremost, a monument dedicated to the glorious victories of Ardashir II, with a giant, six meter tall statue of said Shah standing right on the middle of its main plaza (4). In time, the city would grow into a prosperous center of commerce and eventually manufacturing, especially of textiles, but its main purpose was to serve as a statement that the days of the children of Odainat were long gone and would never return. It was, in the words of the famous Chinese Manichean traveler and missionary Xuanzang, who visited Iran and later Europe in the sixth century, "the proof of the extent of human pettiness. Though prosperous, this place's true reason to exist is to be nothing more than an insult to people who died long ago".
Yazdegerd's other priority was ensuring the survival of his dynasty by having as many heirs as possible, should something very bad happen to one or two of them. So worried he was that it is believed that he had two official wives instead of just one, like previous Sasanian kings did. While it is known that the Shah usually had a harem (an institution that existed since the days before the Achaemenids) composed of multiple wives and more concubines, there was usually a single chief consort who sired the heir to the throne. Whether the women in question, Boran and Shirin (the latter of whom is believed to have been a Christian), actually shared the position is unknown, but the fact they were political adversaries who desired for one of their children to become King of Kings following the incumbent's death was a certainty.
Boran, who most sources indicate to have been the chief consort, had the upper hand in the succession dispute right from the get go by giving Yazdegerd two healthy sons, Ardashir and Shapur, who were born in 349 and 356 respectively. Both were given a superb education, and Ardashir in particular began to show great promise and intelligence from a young age, and began to be introduced to state ceremonies and council meetings after reaching the age of fourteen. However, this blatant favouritism also gave him an arrogant, impetuous and abrasive personality, which only worsened after being appointed to the governorship of Osroene (to the east of Syria) after his twenty first birthday. Sure that he would eventually take the throne, the elder prince built a large retinue around himself, and the military experience earned by fighting Hunnic raiders from Anatolia created fears that he would overthrow his aging father at the first opportunity.
Shapur, meanwhile, was a completely different character. Trapped under his brother's shadow, he grew into an envious and cunning individual, eager for glory, fame and most importantly, power. As governor of the province of Palestine, he proved himself to be an able politician, earning the respect of the local Christian and Jewish communites through the construction and restoration of many churches and synagogues. He also forged connections with nobles who were put off by Ardashir's arrogance, and cultivated good relations with Yazdegerd by behaving like an obedient son, while the actual heir seemed hellbent on eclispsing him.

Shirin, in comparison, was far more unlucky than her competitor. Her first surviving son with the Shah, Narseh (born in 353), was born with a withered right arm, which was supposedly twenty centimeters shorter than his healthy one, a birth defect that almost completely disqualified him from the line of succession, despite his sharp mind (5). Because of this, he was completely disinterested in politics, choosing instead to become a scholar who eventually amassed a great collection of books and manuscripts that focused on multiple subjects, from poetry to astronomy and mathematics. The ruins of his private library can still be seen today in Shushtar, and he was one of the first prominent Iranians to realize that the material known today as paper could be very useful to the imperial bureaucracy.
It was Shirin's second son, Kavad, that truly buried her hopes of having one of her children take the throne. Born in 361, right after Tiridates' death, Kavad proved himself to be a difficult child to say the least, rarely paying attention to his tutors and often sleeping during lessons. That was when he showed up at all, since the prince often fled from the palace, only to be found days later mingling with commoners, which was basically the ancient version of skipping school. Thus, after reaching adulthood, Kavad was seen as a lazy, uneducated individual who was nothing more than a country bumpkin who had way too much time and money on his hands, wasting both of them on extravagant parties that had way too much alcohol. In short, he was a source of embarrassment to his parents. However, there were always ambitious nobles who hoped to use such a person as a puppet while they did the real ruling, and Farrukhan Suren, eager to recover his family's ancestral lands, was one such noble.
Yazdegerd I, King of Kings since 334, was struck down by a severe fever at the age of sixty-one in 385. Though he refused to die at first, everyone knew that his time was running out, and he was now powerless to stop his sons from starting a chain of events that would lead Iran to the brink of destruction.
Far, far to the east, a man watched these events unfold with a satisfied smile in his face. With a countless number of spies all over Iranian territory, many of whom were nobles who had grown tired of the bickering Sasanians, he was keenly aware of everything that was going on in the country, and was just waiting for the perfect opportunity to seize it all for himself. The man had already humbled the armies of the Celestial Empire, long believed to be invincible, but his appetite for glory and wealth wouldn't cease until he became the undisputed master of the entire world.
It was said that the mere mention of his name made the earth itself shake in fear. And the people of Iran, noble and humble alike, would do so for many years.

Notes:
(1) Remember this guy's name, he is important.
(2) A recognition that Egypt just isn't worth conquering right now, not until a counter to Syrian Fire is discovered.
(3) That's actually Caesarea Maritima.
(4) Think of this statue, but for a different Shah.
(5) He suffers from Erb's palsy. It's the same condition that gave German emperor Wilhelm II his crippled left arm.
