The Brothers Zarathustra – 913-956
The two men who would change the course of Iranian history and reverse Persia’s seemingly inevitable drift towards Islam were the two Ziyarid brothers – Mardavij and Vushmgir. Although they claimed royal heritage, they emerged out of the violent tribes of Gilan – one of the provinces on the shores of the Caspian Sea in which the old religion of Zoroastrianism remained widespread into the tenth century.
The tenth century was an unstable time in Persian history. As the authority of the Abbasids had retreated in the preceding century, indigenous dynasties had gained power throughout the Iranian world and proceeded to squabble endlessly over the Caliphate’s old lands. It was into this chaotic and uneven power struggle that the Ziyarids emerged.
The eldest of the brothers, Mardavij, entered military service around 913 and was shortly followed by Vushmgir. The sovereign they served was the Alid Emirate – a Zaydi Shia state that ruled over the southern shore of the Caspian. As the Alid state collapsed in the late 920s, the Ziyarid brothers joined their liege lord Asfar ibn Shiruya in a takeover of most of the Emirate’s old lands in Tabaristan. As a close ally of Asfar, Mardavij was rewarded with governorships and a role as a key general. However, Mardavij had ambitions much greater than this and in 930 turned against his lord, overthrowing Asfar and sending him into exile while establishing himself as ruler of Tabaristan.
Mardavij was neither content to accommodate himself to the Muslims powers of the region nor even limit himself to his newly acquired lands. Openly Zoroastrian, he was fiercely hostile to Islamic dominance and attracted popular support with promises to restore Persian tradition. From 930 he struck southwards into the Persian heartland and quickly won a string of victories – conquering the crucial central-Iranian city of Isfahan, where he established his capital, and having his authority recognised as far away as Ahvaz in Khozistan and Shiraz in Fars. As his authority grew, Mardavij had himself coronated in Isfahan with a crown designed to mimic that of the Sassanian Shahs of old and openly spoke of marching on Baghdad to topple the ailing Abassid Caliphate and restore the old imperial capital of Ctesiphon.
From this moment of great power, things soon fell away. In 935 Mardavij was murdered by his own Turkic slave soldiers, while his Muslim neighbours struck upon his young realm as vultures. As Vushmgir attempted to hold together his brother’s inheritance, he was forced to fall back to his core territories along the Elburz mountains in Tabaristan, south of the Caspian. The Ziyarid state appeared to have been reduced once more to a minor player in Persian politics, isolated by the Shia Emirates to its south and west, the powerful Saminids in the east and the prestigious Abassid Caliph in Iraq.
Perhaps more significant than the loss of land, the transition from Mardavij to Vushmgir threatened the Zoroastrian character of the Ziyarid state. In contrast to his brother, Vushmgir was no zealot and had shown a strong willingness to ingratiate himself to Islam. For much of his life he had maintained ambiguous religious loyalties, posing as a Muslim to some and a Zoroastrian to others. However, after his brother’s deaths and his retreat back to Tabaristan, Vushmgir Ziyarid would make the fateful decision to embrace the faith of his ancestors. Gathering his camp followers, he swore an oath to take up his brother’s legacy and liberate the Persian people from Muslim rule and relight the flames of Zarathustra throughout the land.
The Ziyarid position in the mid-930s remained very insecure, with the Zoroastrian state surrounded on all sides by hostile Muslim powers. Vushmgir was fortunate that during this period a war between the Abassid Caliph in Baghdad and a coalition of Persian Shia Emirs drew attention to the south. Indeed, through a series of short border excursions he successfully expanded westward into Gilan and Daylam, his clan’s ancestral homeland.
The would-be Persian liberator would be forced to look to the west for an ally against the Muslims – to the lands of the Armenians. King Abas of Armenia saw in a valuable potential weapon with which to strike against the Muslim foes that had long threatened his people’s independence. At the close of the 930s the two powers entered into an alliance that saw them jointly invade the Yazdid Emirate of Azerbaijan and divide the land between themselves, with the Ziyarids capturing the important city of Baku and its large Zoroastrian population. The Armenians would continue to sponsor Vushmgir for the next decade with the support of mercenaries that made his armies almost unstoppable.
Victory in the north gave Vushmgir the confidence to launch into a holy war of Persian liberation to the south, striking against the rich Emirate of Jibal in 942. Crushing the Muslim army at Khourabad, he proceeded to capture the great cities of Hamadan and Qom, as well as the jewel of central Persia – Isfahan, briefly his brother’s royal capital. These Zoroastrian conquests were deeply alarming to forces of Islam, and the Abassid Caliphate rallied a degree of unity among the Islamic community as it sent an army over the Zagros to push Vushmgir back into the north in 945. The Arabs won a string of battlefield victories that sent the Ziyarids scattering to their fortresses. It was at this moment that good fortune and Ahura Mazda shone upon the Persians, as an outbreak of cholera in the Caliph’s army during his siege of Isfahan forced him to fall back. A truce was agreed in 946 than saw the Arabs take the mountainous passes of Luristan, but leave the rich cities to the east in Ziyarid hands. Not content to rest on their laurels, the Ziyarid thirst for land led to a further short war in 947-948 against the Kurdish Sallarid Emirate that saw the Zoroastrian zealots capture southern Kurdistan and its sacred Fire Temple.
The Zoroastrian conquests of the mid-tenth century left an incredible trauma on the psyche of Islamic Iran. The social order had already been rocked by the retreat of the stable order the Caliphate had once brought with it and the descent of the region into strife and war. Yet the Zoroastrian resurgence had been a far greater threat. Throughout the wider Iranian world, Zoroastrians remained a sizeable minority, and openly celebrated the conquests of Mardavij and Vushmgir while professing an ideology that presented the brothers as liberators of not just their fellow Mazdans but of the Persian nation from Arabic and Muslim domination. Casting out the old Muslim clerical and landed elite wherever they went – they presented a very real challenge to the social order as well as the religious one.
As panic swept Iran, revolutionary apocalypticism began to take hold. The most influential of these eschatological sects were the Garakani. Claiming that Allah had condemned Islamic society for straying from the truth of Muhammed, this violent movement took hold in the southern province of Fars, home to the Buyid Emirate. The Garakani claimed that all who opposed the teachings of their Iman, Mirza Garakan, were no longer Muslim and were therefore enemies of the true faith. In the early 950s they destroyed the Buyid state, but quickly found themselves incapable of assuming power over the entire region – seeing the former Emirate splinter into half a dozen competing statelets. Taking advantage of the chaos, Vushmgir launched an invasion of the region in 954.
Having conquered the south, Vushmgir would triumphantly be crowned Shah of Persia in Isfahan 956, completing the work set out by his brother. Yet this victory was far from complete. The Islamic world had been stunned by the rebirth of a Zoroastrian Persian state in the space of a single generation, but by the time of Vushmgir’s coronation the armies of Allah were already preparing themselves for retribution.
