The Battle of Lake Hód (Hungarian: Hód-tavi csata) was fought between the Kingdom of Hungary and the Cumans in September or October 1282. King Ladislaus IV of Hungary successfully repelled the invaders.
Background
In the midst of imminent danger of the Mongol invasion, the first Cumans settled in the Kingdom of Hungary, after King Béla IV of Hungary offered refuge to Khan Köten (Kötöny) and his people in 1239. The king's decision caused social, economic and political tension and the settlement of masses of nomadic Cumans in the plains along the river Tisza gave rise to many conflicts between them and the local villagers. When the Mongols reached the border and invaded Hungary in the spring of 1241, several Hungarians accused Köten and their Cumans of cooperating with the enemy. The Cumans left Hungary amid plunder, after an angry mob massacred Köten and his retinue in Pest. With their departure Béla lost his most valuable allies and the Mongols decisively defeated his royal army in the Battle of Mohi on 11 April 1241. Following the withdrawal of the Mongols in the next year, Béla invited the Cumans to return and settle in the depopulated plains between the rivers Danube and Tisza, in return for their military service. He even arranged the engagement of his firstborn son, Stephen, who was crowned king-junior in or before 1246, to Elizabeth, a daughter of a Cuman chieftain.
The issue of the social integration of the Cumans had marginalized in the following decades. Their military value became a significant portion within the Hungarian royal army, which also contributed to the formation of the light cavalry structure. Cumans participated in military campaigns abroad, for instance during the fights against the Duchy of Austria and the Kingdom of Bohemia. In the civil war between King Béla IV and his son Stephen, both sides tried to gain Cuman support. During this conflict, in 1264, Béla sent Cuman troops to fight his son Stephen, despite that the Cumans officially belonged to the suzerainty of the latter, who had taken the title of "Dominus Cumanorum". After Stephen's victory in the civil war, significant number of Cumans intended to leave Hungary amid looting and plunder, however, they were important militarily to the royal authority. Around April 1266, Stephen successfully persuaded them to remain in Hungary, when launched a punitive expedition against them.
After the death of Stephen V in 1272, the 10-year-old Ladislaus IV (subsequently also known as Ladislaus the Cuman) ascended the Hungarian throne under the regency of his mother Elizabeth the Cuman, but in fact, baronial parties administered the kingdom. Hungary fell into feudal anarchy, when various groups fought for supreme power. Between 1277 and 1279, Ladislaus, who was declared to be of age, has temporarily succeeded in domestic and foreign policy. Pope Nicholas III sent Philip, Bishop of Fermo, to Hungary to help him restore royal power in early 1279. However, the arrival of the papal legate had an overall negative impact on domestic political stability. The bishop sensed angrily that majority of the Cumans has retained their pagan religion and customs in recent decades within a Christian realm. Philip extracted a ceremonious promise from the Cuman chieftains of giving up their pagan customs, and persuaded the Hungarian monarch to swear an oath to enforce the keeping of the Cuman chieftains' promise. During the assembly at Tétény in the summer of 1279, the so-called Cuman laws were passed, which prescribed social and cultural assimilation of the Cumans. They, however, did not obey the laws, and Ladislaus IV, himself being also of half-Cuman descent, failed to force them. As a result, Philip excommunicated the monarch and placed Hungary under interdict shortly thereafter. After mutual imprisonment and political struggles, Ladislaus IV took a new oath to enforce the Cuman laws in the spring of 1280. In response, many Cumans decided to leave Hungary instead of obeying the legate's demands. This fundamentally endangered the effectiveness of the Hungarian military capability. The king was chasing the outgoing Cumans as far as Szalánkemén (now Stari Slankamen in Serbia), but could not hinder them from crossing the frontier. According to the king's donation letter to Thomas Talpas in 1288, the Hungarian army crossed the Southern Carpathians in order to bring back the "secretly defected Cumans from the borderlands of the Tartars". The Cuman invasion of Hungary occurred following that.
Date and location
Pre-19th century historiography claimed that the battle took place at the Lake Hód that once existed, near present-day Hódmezővásárhely. Late 19th-century historiography – Károly Szabó and Gyula Pauler – considered the Cuman's incursion and the Battle of Lake Hód took place in early August 1280, based on a royal charter – contains that a certain castle warrior Denis is granted nobility because of his participation – which later proved to be a forgery. Historians István Gyárfás and Károly Szabó considered the place of the battle was a settlement [locus] called Hód instead of a lake [lacus]. Gyula Pauler placed the battle site to a field called Hód near Makó. According to Pauler's reconstruction, the Cumans rebelled against Ladislaus IV, when the monarch took his second oath to enforce the Cuman laws after his liberation from captivity. They plundered the region between the area of rivers Tisza and Maros (Mureș), until they were defeated by Ladislaus IV in the Battle of Lake Hód in August 1280. Thereafter, the king marched to Székesfehérvár and gathered an army in the autumn of 1280 to persuade the outgoing Cumans to stay in Hungary.
In his study published in 1901, historian János Karácsonyi put the date of the battle to late April or early May 1282. He argued the diplomas Pauler had previously put forward as an argument, only refer to domestic rebellion of the Cumans occurred in the autumn of 1280, while other charters suggest that the Battle of Lake Hód chronologically took place after the siege of the castle of Szalánc (today Slanec, Slovakia) and the defeat of Finta Aba, a rebellious lord, which occurred in 1281. In addition, Karácsonyi proved that the aforementioned charter (allegedly issued on 21 August 1280) regarding the ennoblement of Denis (ancestor of the Mokcsay family) is non-authentic. The historian emphasized that the Illuminated Chronicle mentions the skirmish under the year 1282, while Ladislaus Miskolc, one of the participants, who was killed in the battle, is mentioned as a living person in 1281. In that year, the king launched a campaign against Finta Aba, which covered about the entire year. In addition, a royal charter from 1283 listed Ladislaus' victories in the following chronological order: Battle on the Marchfeld (1278), Siege of Szalánc (1281) and the Battle of Lake Hód, while another royal charter from the next year states that the battle took place before the siege of Bernstein Castle (Borostyánkő), which occurred in 1284. In another study (1907), Karácsonyi cited another document, which proves that Demetrius Rosd, who also fell in the battle, was still alive in the first months of 1282. In summary, Karácsonyi argued the Cumans' revolt took place in the autumn of 1280; they intended to leave Hungary, and Ladislaus IV was unable to defeat the Cumans and prevent them from doing so. A year and a half later, in the spring of 1282, the Cumans led by a certain Oldamir (also Oldomerus or Oldamur) invaded the kingdom, but the monarch repelled their attack at the Lake Hód.
Local historian Károly Czímer – while accepted the date 1282 – refused the identification of the place of the battle with the area of Hódmezővásárhely, arguing that the two sites were first connected in the 18th century by local Calvinist pastor and scholar Benjámin Szőnyi. This tradition is rooted locally in Hódmezővásárhely, then was integrated into the national historiography too throughout the 19th century. Czímer claimed that the battle took place near the village of Hód in Arad County, later called Temesszécsény (present-day Seceani in Timiș County, Romania), arguing that the village and the surrounding area lay along the usual military marching area of the Cumans. Czímer's theory has not been embraced by the subsequent historiography, while the area of Hódmezővásárhely was unanimously accepted.
Despite Karácsonyi's new research in the early 20th century, later scholars were divided on the question of when the battle took place. Bálint Hóman put the date to 1280, accepting Gyula Pauler's argument, in the interwar period, in addition to the first volume of the 1960s academic history series (Magyarország története 1.: Magyarország története az őskortól 1526-ig) during the Communist regime. Historian Gyula Kristó considered the battle took place in the summer of 1280 (although he mentioned the other theory), while his frequent scientific opponent György Györffy narrated the event under the year 1282. In his 1977 study, László Blazovich contested Karácsonyi's arguments regarding the date 1282. He argued the authenticity of all three charters, which suggest that the battle took place in that year, is questionable, while there are other documents, where the military events of the 1280s are mentioned in a different order. Blazovich also questioned the credibility of the victim list of the battle provided by the contemporary Simon of Kéza's The Deeds of the Hungarians, because the chronicler presumably "could not distinguish between warriors who had fallen in battle and those who had recovered from their serious injury". According to Blazovich's interpretation, there was only a single skirmish between the monarch and the Cumans in the summer of 1280. In a response to the adoption of the Cuman laws, they rebelled against the royal power and devastated the region between the area of rivers Tisza, Maros and Körös (for instance, they stormed Egres Abbey, Hájszentlőrinc Chapter and Sövényvár Castle). Ladislaus IV gathered his army consisted of nobles from Northeast Hungary and Transylvania, and marched from Várad (today Oradea, Romania) to the area, where he defeated them at the Lake Hód in late October or early November 1280.
