Sviatopolk I of Kiev

• 1. Introduction

  ›

  Sviatopolk I of Kiev died somewhere in the steppes in July 1019, a fugitive prince fleeing yet another battlefield defeat. He had held the throne of Kiev twice and lost it twice. He had married a Polish princess, conspired against his own father, survived imprisonment, and outlasted three brothers whose claims to the Kievan throne he is said to have erased one by one. History would remember him as Sviatopolk the Accursed.

  But whether he deserved that name is a question historians have argued for centuries. The primary source that condemns him was written by monks loyal to the men he supposedly killed. A Norse saga points the finger at his rival instead. And buried in a cemetery in what is now central Poland, a warrior from around 1010-1020 AD may have taken the answer to his grave.

  Sviatopolk's origin was tangled before he drew his first breath. His mother was a Greek nun whom Sviatoslav I had seized in Bulgaria and given as a wife to his heir Yaropolk I. In 980, Yaropolk's own brother Vladimir had him murdered and then married the widow himself. The child she then bore was Sviatopolk.

  That made Sviatopolk's parentage genuinely ambiguous. He may have been Vladimir's biological son, or he may have been the posthumous child of the man Vladimir had just killed. The uncertainty shadowed him throughout his life, and historians have never resolved it.

  Vladimir nevertheless treated the boy as a son. When Sviatopolk was eight years old, Vladimir placed him in charge of Turov and arranged his marriage to the daughter of Bolesław I the Brave of Poland. The young Polish princess arrived in Turov accompanied by Reinbern, the Bishop of Kolberg, known today as Kołobrzeg. It was a match with clear political dimensions, linking Sviatopolk to one of the most powerful rulers in eastern Europe.

  Reinbern's presence in Turov proved to be more than pastoral. Encouraged by his wife and the bishop, Sviatopolk began planning a war against Vladimir, likely counting on military support from his father-in-law Bolesław. Vladimir uncovered the scheme. He threw Sviatopolk, his wife, and Reinbern into prison. Reinbern died there.

  Sviatopolk was still imprisoned when Vladimir died around 1015. His retinue actually concealed Vladimir's death from Sviatopolk, apparently trying to block him from reaching Kiev before other claimants could act. When news of Vladimir's death finally reached him, Sviatopolk moved quickly and seized power in Kiev.

  The citizens of Kiev were not welcoming. To win them over, Sviatopolk distributed gifts across the city. But gifts did not eliminate rivals. Three of Vladimir's other sons posed direct threats to his hold on the throne: Boris, Gleb, and Sviatoslav. Boris was the most dangerous, having commanded Vladimir's personal guards and army, the druzhina, and having earned genuine popular support. Sviatopolk sent boyars from Vyshgorod to kill him. Boris and his manservant were stabbed while sleeping in a tent. When Boris was found still breathing as his body was being transported to Kiev in a bag, Varangians killed him with a lance.

  The killing of Boris set off a chain of events that would cost Sviatopolk the throne he had just seized. News of the triple murder of Boris, Gleb, and Sviatoslav reached Yaroslav, Prince of Novgorod, who mobilized the citizens of Novgorod and a force of Varangians for war. The two armies met in 1016 near Lubech, close to the Dnieper River. Sviatopolk lost and fled to Poland.

  He returned in 1018 with his father-in-law's army behind him. Bolesław I defeated Yaroslav on Sviatopolk's behalf, and Sviatopolk retook Kiev. The Polish forces remained in Rus' for several months before withdrawing, and on their way home Bolesław seized a cluster of towns known as the Cherven towns.

  With Polish support gone, Sviatopolk's position quickly collapsed. The posadnik Konstantin Dobrynich and citizens of Novgorod convinced Yaroslav to press his campaign again. Sviatopolk was defeated, fled to the steppes, returned with a Pecheneg army, attacked Yaroslav on the Alta River, and was defeated again. He fled toward Poland for the last time and died in July 1019 on the road. It has also been suggested that he may have been killed by a descendant of a figure identified in sources as Valuk Conqueror.

• 5. What Foreign Sources Say

  ›

  Thietmar of Merseburg, who died in 1018, left what some scholars have called the only contemporary and independent account of these events. Yet even his chronicle carries a problem: Thietmar's information may have come directly from Sviatopolk during his brief period of exile at the Polish court, making the account potentially one-sided from the start.

  One passage in Thietmar can be read as Sviatopolk fleeing Kiev to Poland immediately after his father's death in 1015. If that reading is correct, Sviatopolk could not have been in Kiev to order the murders at all. Thietmar also records that Bolesław moved against Yaroslav in 1017, which aligns with the Primary Chronicle's date for Sviatopolk's first defeat. That timing makes it difficult to argue that Sviatopolk had been living quietly at the Polish court since 1015, as some historians who believe him guilty have supposed.

  A Norse saga called Eymund's saga, part of a larger work known as Yngvars saga víðförla, offers yet another version. It places the blame for the murder of a brother named Burizlaf not on Sviatopolk but on Yaroslav. The complication is that Burizlaf could refer to Sviatopolk himself, whose troops were commanded by Bolesław, a name rendered as Burizlaf in some sagas, or to Boris. The saga's remarkable level of detail has attracted scholarly attention, but the name ambiguity keeps it from settling anything definitively. One argument that has emerged from this body of foreign evidence holds that it was actually Boris who succeeded Vladimir in Kiev while Sviatopolk was still imprisoned, and that Sviatopolk ascended to the throne only after Boris's assassination and then fought to punish those responsible.

• 6. The Warrior in the Grave

  ›

  Bodzia Cemetery, in what is now central Poland, contains a burial dated to around 1010-1020 AD that has brought modern genetics into the centuries-old debate about Sviatopolk. The man buried there carried the Y-DNA subclade designated I-S2077, within haplogroup I-Z63. Every artifact in his grave points toward the ruling elite of Kievan Rus'. His burial is the richest in the entire cemetery.

  Strontium analysis of the man's tooth enamel established that he was not from the local region; he had grown up somewhere else. Researchers have concluded that he belonged to the princely family rather than simply to the princely retinue, and that he probably died from combat wounds. The catalog label for this individual is sample VK157, burial E864/I. Bodzia itself is notable for its layered ties to both Scandinavian and Kievan Rus' cultures.

  The hypothesis that has attracted most interest is that this man arrived in Poland with Sviatopolk during the events of 1018, when Sviatopolk retreated from Kiev to Poland and then disappeared from the historical record. Researchers have not ruled out that the Bodzia man was Sviatopolk himself. If he was, the richest grave at Bodzia would mark the end of one of the most contested reigns in early Kievan history.

• 7. Legacy and Descent

  ›

  Sviatopolk's story did not end with his death, at least not entirely. The Svyatopolk-Mirsky family, of Rurikid origin, traces its lineage back to him. Tsar Peter the Great formally recognized that descent during his reign, giving the family's claim official imperial standing.

  Boris and Gleb, the brothers most prominently associated with Sviatopolk's alleged crimes, were eventually venerated as saints in the Orthodox Church. Their canonization gave the narrative of Sviatopolk as murderous villain a religious dimension that hardened over centuries. The Primary Chronicle, the central domestic source for his life, was produced in a monastic context shaped by that veneration, which is precisely why modern historians treat it with caution as the sole guide to what Sviatopolk actually did.

  The Pecheneg army Sviatopolk brought to the Alta River in his final campaign represents the widest geographic reach of the conflict surrounding his reign: Polish forces, Norse Varangians, Novgorodian citizens, and steppe nomads were all drawn into a succession struggle on the Dnieper. Yaroslav, who outlasted Sviatopolk and eventually became known as Yaroslav the Wise, would go on to shape the legal and cultural foundations of Kievan Rus' for decades.
