Battle of Kulikovo

• 1. Introduction

  ›

  The Battle of Kulikovo, fought on the 8th of September 1380, was the moment a nine-year-old boy grew into a conqueror. Dmitry of Moscow had been that boy in 1359, when his father, Prince Ivan II, died and rival princes scrambled for power. Two decades later, Dmitry stood at the edge of the Don River with the largest army the Moscow princes had ever assembled, facing Mamai, the most powerful military commander of the Golden Horde. The questions the battle raises are worth sitting with. Why did Mamai, surrounded by threats on every side, choose Moscow as his target that autumn? How did a Russian army that almost certainly numbered in the thousands, not the hundreds of thousands the chronicles claim, defeat a force that had dominated the region for over a century? And why, despite a decisive Russian victory, did Mongol domination continue for another hundred years?

• 2. Mamai's Fragile Grip

  ›

  After the killing of Khan Berdi Beg in 1359, the Golden Horde fell into a period of internal turmoil known as the Great Troubles. Mamai, who was Berdi Beg's son-in-law and his chief military officer, seized power over the western portion of the Horde. The critical problem he faced was one of legitimacy. He was not a Genghisid, meaning he was not a descendant of Genghis Khan, and without that bloodline he could not rule as khan himself. His solution was to place puppet khans on the throne. He installed Abdullah Khan in 1361, and after that khan's mysterious death in 1370, he enthroned Muhammad Bolak. True Genghisids with legitimate claims to power circled constantly around him, and from the east a rival named Tokhtamysh, backed by Tamerlane, pressed toward full control of the Horde. Mamai's grip was further weakened with each military setback. His forces suffered a defeat at the Battle of the Vozha River in 1378, when Moscow forces turned back his warlord Murza Begich. Every loss chipped away at the authority he needed to extract tribute and hold his coalition together. By 1380, with Tokhtamysh closing in, Mamai was fighting a battle on two fronts.

• 3. Moscow on the Rise

  ›

  Moscow in the mid-14th century was not yet the dominant power it would become, but it was aggressively building toward that position. In 1300, Moscow had seized the city of Kolomna from Ryazan, and the prince of Ryazan was later killed after years in captivity. When Prince Dmitry was only nine years old in 1359, Moscow's elites refused to accept the rival claim of the prince of Nizhny Novgorod to the Grand Duchy of Vladimir. They used both armed force and bribes to various khans, and by 1365 forced Nizhny Novgorod to give up its claim. A decade later, in 1375, the Prince of Tver received a jarliq, a legal pronouncement, from Mamai granting him the Grand Duchy. Dmitry responded by marching a force larger than what he would later bring to Kulikovo directly to Tver and compelling its surrender. Mikhail of Tver formally recognized himself as the "little brother" of the Moscow prince and committed to joining Moscow in wars against the Tatars. The Grand Duchy of Lithuania also pressed against Moscow's borders, launching three campaigns between 1368 and 1372. But when the Lithuanian prince Algirdas died in 1377, his sons Andrei of Polotsk and Dmitri of Bryansk defected from the succession struggle and allied with Moscow instead. These two princes may have fought alongside Dmitry at Kulikovo.

• 4. The Field of 8 September

  ›

  On the 20th of August 1380, Prince Dmitry moved his army west along the Oka River after receiving word of Mamai's approach. He crossed the river at the town of Lopasnya on August 24-25 and marched south. By September 6, the army reached the Don River and held a council. The decision was made to cross before Mamai's allies, Jogaila of Lithuania and Oleg of Ryazan, could link up with the Horde. Crossing the Don destroyed any path of retreat. The morning of the 8th of September began in thick fog. According to the Nikon Chronicle, after the army crossed, the bridges were destroyed behind them. Dmitry made a remarkable personal decision: he exchanged clothes and horses with a trusted boyar named Mikhail Brenok, so that the enemy would target Brenok under the grand banner while Dmitry fought as an ordinary soldier in the frontlines. That choice nearly cost Brenok his life and, before the day was over, did cost Brenok exactly that. The Russian army organized into six regiments, including an Ambush regiment hidden in an oak grove under Vladimir the Bold and Dmitry Bobrok, the Grand Prince's brother-in-law. The battle opened with a single combat between Alexander Peresvet, the Russian champion, and a Horde champion called Temir-Murza. Both men drove their spears into the other on the first pass. Both fell. The duel settled nothing.

• 5. The Ambush That Broke the Horde

  ›

  The main clash of armies came roughly at what the Expanded Chronicle Tale calls "the sixth hour of the day," which corresponds to approximately 10:35 in the morning. Medieval German historian Albert Krantz, writing in his book Vandalia, described the fighting style of both sides: neither army stood in large static formations; both rushed to throw missiles, strike, and then retreat. Military historian Kirpichnikov, an expert on medieval warfare, argued that the armies fought in several separate consolidated units, each trying to maintain order. When one unit broke, survivors fled and a fresh unit replaced them. The tight terrain at Kulikovo Field denied the Horde its usual advantage of flanking maneuvers. Even so, the Tatars gradually gained the upper hand. They broke through to the banner of the Large Regiment and killed Boyar Brenok. The Left Hand regiment was overrun. Some Moscow recruits panicked. With the Tatars pressing their entire force into the attack, the Russian line began to collapse. At that moment, the Ambush regiment struck from the oak grove, hitting the Horde's flank with fresh cavalry. Exhausted fighters and horses could not hold against the fresh assault. The Horde's line broke, and the Russians chased the fleeing Tatars for over 50 km, as far as the Krasivaya Mecha River. A third of the commanders of all 23 banners died in the fighting. Dmitry himself was found wounded and unconscious among the dead, his entire escort killed or scattered.

• 6. After the Battle

  ›

  Jogaila, learning of Mamai's defeat, turned his Lithuanian army back without engaging. Prince Oleg of Ryazan, whose cautious gamble of siding with Mamai had failed, fled to Lithuania according to the Nikon Chronicle. The Ryazan boyars accepted Moscow governors, and when Oleg eventually returned he was forced to recognize Dmitry as his sovereign. Mamai himself escaped to the Genoese stronghold of Caffa in Crimea. He assembled a new army, but without even a puppet khan his nobles defected to Tokhtamysh. Mamai fled to Caffa a second time and was killed there. Historian Gorsky noted that Tokhtamysh received the most concrete political benefit from the whole encounter: Mamai's defeat handed him unified control of the Golden Horde, ending a twenty-year split in one stroke. That outcome soon came back to trouble Moscow. In 1382, Tokhtamysh burned Moscow and forced Dmitry Donskoy to accept him as sovereign. The question of Ryazan prisoners taken during the chaotic retreat from Kulikovo remained a live diplomatic issue for two decades, mentioned explicitly in the Moscow-Ryazan treaties of 1381 and 1402. Russian vassalage to the Golden Horde did not formally end until 1480, following the Great Stand on the Ugra River, a full century after Kulikovo.

• 7. Sources and Silences

  ›

  Only five primary sources about the Battle of Kulikovo survived into modern times: one in Church Slavonic, two in Middle High German, and two Bolgar manuscripts from the end of the 17th or 18th century. No sources from the Tatar side are available. According to scholars, if Tatar records were ever written, they were probably destroyed when Timur burned down the Golden Horde's archives in Sarai. The Church Slavonic materials spawned what historians call the Kulikovo cycle, a body of medieval Rus' literature larger than any other single historical event had generated. Its main works are the Chronicle Tale, the Zadonshchina ("The Battle beyond the Don"), and the Skazanie o Mamaevom poboishche, known in English as "The Tale of the Battle with Mamai" or the "Narration." The Zadonshchina modeled itself on The Tale of Igor's Campaign and kept a chivalric military tone, replacing that earlier work's Slavic pagan imagery with the idea of fighting for the Rus' Land and the Christian faith. The "Narration" rewrote the same events with far more religious content, adding miracles, constant prayers, and an invocation of Volodimer I of Kiev baptizing the Rus' Land. As of 2022, only six manuscripts of the Zadonshchina were known to exist, while over a hundred copies of the "Narration" have survived, a gap that reflects how much the later, more religious version displaced the earlier one. The sources also contradict each other on basic facts, including whether Dmitry fought in disguise or openly, and whether he emerged from the battle wounded or without a scratch.

• 8. Archaeology and Scale

  ›

  The question of how many soldiers actually fought at Kulikovo has occupied historians for generations. Chronicle sources claimed figures of 150,000-200,000 Russian troops, with later literary sources inflating this to 300,000 or even 400,000 armored soldiers. Military historian General Maslovsky, writing in 1881, estimated 100,000-150,000 men. Historian Razin in 1957 put the figure at 50,000-60,000. Medieval warfare expert Kirpichnikov, in 1966, argued the maximum strength of six regiments on Kulikovo Field could not exceed 36,000. By 2014, archaeologist Dvurechensky, an employee of the Kulikovo Field museum, estimated the Russian army at just 6,000-7,000 warriors. The archaeology underpins that deflation. According to Dvurechensky's 2008 catalogue, the physical evidence of weapons from the time of the battle amounts to four spearheads and two fragments, a javelin tip, two axe blade fragments, a fragment of an armor plate, a fragment of chain mail, and several arrowheads. Many weapons found nearby date to the 16th-18th centuries and cannot be connected to the 1380 battle at all. A Persian blade dug from the field as recently as 2009 was discovered in a local family's home and transferred to the museum. The precise location of the battlefield itself was only definitively settled by Dvurechensky's team in 2005, who placed it between the rivers Nepryadva and Smolka on the right bank of the Nepryadva. A minor planet, 2869 Nepryadva, discovered in 1980 by Soviet astronomer Nikolai Stepanovich Chernykh, carries the name of that river into the solar system.
