The Hungarian Kingdom from 1301 to Mohacs

From the end of the Árpád dynasty in 1301 to the defeat at Mohács in 1526, the Hungarian Kingdom faced recurring struggles over who could exercise royal authority and how the realm should be defended. Located in central Europe, its lands encompassed much of the Carpathian Basin and included communities with different languages, local institutions, and religious traditions. The crown was also held in personal union with Croatia, whose political life had its own powerful families and offices. Latin served as a language of administration, while Hungarian, Croatian, German, and several Slavic languages were among those spoken across the kingdom.

The period was not a steady rise or decline. Angevin rulers rebuilt royal power after a succession crisis, but later kings had to negotiate with nobles whose resources could rival the crown’s. Ottoman expansion put increasing pressure on the southern frontier, while the kingdom’s ability to raise money and maintain troops changed sharply from reign to reign. These tensions came to a head at Mohács, where King Louis II died in battle in 1526.

Restoring royal authority after 1301

The death of Andrew III in 1301 ended the Árpád dynasty and opened an interregnum, a period in which the succession was disputed. Powerful lords, often called oligarchs, had taken control of royal castles and large territories. They could demand obedience from local populations and, in some regions, acted with considerable independence from the crown. Matthew Csák dominated lands in the north, Ladislaus Kán governed Transylvania, and Ugrin Csák held territory farther south. In Croatia, the Šubić and Babonić families also wielded great power; Paul Šubić even issued coins in his own name.

Several claimants sought the throne. Charles of Anjou was crowned, but many leading lords backed first Wenceslaus and then Otto of Bavaria. Charles secured broader recognition in 1310, yet recognition did not immediately give him control of the kingdom. Supported by church leaders and an increasing number of lesser nobles, he fought the great lords in a series of campaigns. His victory at Rozgony in 1312 weakened his opponents, although Matthew Csák remained largely autonomous until his death in 1321. The Šubić and Babonić families were brought under royal authority by 1323.

Charles I strengthened the crown by rewarding supporters with temporary offices and their associated revenues rather than permanently granting away large parts of the royal domain. Families who depended on these appointments had reason to remain loyal to him. The arrangement helped restore central government, although royal authority continued to depend on the king’s ability to reward service and command military support.

Angevin revenues, towns, and rural life

Charles reorganised royal income from customs, salt, mines and coinage. Landholders could retain one-third of the mining royalty from mines on their estates, encouraging them to develop deposits while leaving the remaining royalty to the crown. Mining and the conversion of bullion into money linked northern producing districts with royal finance and international commerce.

Under Charles’s son Louis I, who ruled from 1342 to 1382, the kingdom maintained an active foreign policy. Louis campaigned in distant territories, including southern Italy, and extended his influence over rulers to the south. His military reach did not always produce lasting control: local rulers could rebel, and his authority over the Romanian principalities of Moldavia and Wallachia remained uncertain. His reign also connected the Hungarian and Polish crowns, as he became king of Poland in 1370.

In the countryside, many peasants cultivated defined plots that they could use hereditarily in return for cash payments and produce owed to a landholder. By the 1350s, peasants had acquired the right to move, although their obligations to landlords continued. A law of 1351 confirmed noble privileges and strengthened the right of landholders to judge offences committed by peasants on their estates. These arrangements were later altered, and the freedom of movement won in the fourteenth century would be restricted again in the fifteenth.

Towns also reflected the kingdom’s varied population. German merchants held a strong position in many urban centres, while Hungarian, Croatian, and Slovak villagers increasingly settled there as craftsmen and traders. In 1381, Louis granted Slovak burghers in Žilina the same privileges as the town’s German burghers, an example of royal action recognising more than one linguistic community within a town.

Sigismund and the challenge of frontier defence

After Louis’s death, disputes over succession led to the accession of Sigismund of Luxembourg, who became king in 1387 through his marriage to Queen Mary. His rule depended on barons, the powerful landholding nobles, even as he sought to establish a more secure frontier against the Ottomans. He granted substantial estates to supporters, while some territories in Croatia, Dalmatia, and Slavonia remained under the control of local lords aligned with his rivals. Croatia’s own political networks and the office of the ban, a leading regional governor, remained important parts of this changing balance of power.

Sigismund’s crusade against the Ottomans ended in defeat at Nicopolis in 1396. He subsequently sought more regular contributions from landholders for frontier defence. The crown relied on estate resources to equip soldiers, while fortresses along the Danube and relations with neighbouring rulers formed further parts of its defensive system.

Counties provided a framework for local administration, and their assemblies gained influence during Sigismund’s reign. In Transylvania a voivode headed regional government. The alliance formed against the peasant revolt of 1437 brought together the privileged Estates of nobles, Székely communities and Saxon towns. Their political rights defined membership, and their allied forces suppressed the revolt.

Ottoman advances and raids continued to affect the southern lands. After taking Golubac on the Danube in 1427, Ottoman forces repeatedly raided nearby regions. Some residents moved to better-protected areas, while South Slavic refugees entered the kingdom and some served in mobile military units known as hussars. In the north, Czech Hussite forces raided during the 1420s and 1430s, adding another military pressure during Sigismund’s later years.

From the Hunyadi regency to the defence of Belgrade

Sigismund died in 1437 and was succeeded by his son-in-law Albert of Austria, a Habsburg ruler. Albert died in 1439 during an unsuccessful military operation against the Ottomans. The Estates, the groups of nobles and church leaders with a role in royal government, then faced competing claims: the infant Ladislaus, Albert’s posthumous son, and Władysław III of Poland were both crowned. The resulting conflict brought the military commander John Hunyadi to prominence.

Hunyadi led the long campaign of 1443–1444, reaching the region of Sofia. At Varna in 1444, the Hungarian-led army was defeated and Władysław was killed. With the kingdom divided over government during Ladislaus V’s minority, the Diet elected Hunyadi regent in 1446. He directed frontier defence while retaining extensive resources and fortified bases.

After capturing Constantinople in 1453, Sultan Mehmed II pressed further into the Balkans. In 1456 his army besieged Belgrade, known in Hungarian as Nándorfehérvár. Hunyadi organised its defence with support from the Franciscan preacher John of Capistrano and his recruits. The defenders forced the Ottoman army to withdraw on 22 July. Hunyadi died in an epidemic soon afterwards. Serbia’s final conquest in 1459 and Bosnia’s in 1463 followed this victory.

Hunyadi’s son Matthias was elected king in 1458, after the death of Ladislaus V. His election followed a period of political conflict in which the Estates had to choose between rival dynastic claims and the need for an effective ruler. Matthias overcame opposition from nobles and outside claimants, and in 1464 he was crowned with the Holy Crown of Hungary. His reign restored a strong, active monarchy, but its military ambitions depended on a heavier and more centralised system of taxation.

Matthias Corvinus: taxation, armies, and royal power

Matthias expanded the crown’s income through regular extraordinary taxes on peasant households, often levied without the Diet’s agreement. In 1467, he reorganised existing revenues and customs in ways that ended earlier tax exemptions. These measures strengthened the royal treasury but provoked resistance, including a revolt in Transylvania in 1467. The king’s forces suppressed it. His government also reformed the administration of justice and promoted capable officials, including people from the lesser nobility, rather than relying only on the leading aristocratic families.

Higher revenues helped Matthias establish and maintain the Black Army, a standing force made up largely of Czech, German, and Hungarian mercenaries. Maintaining such an army allowed the king to campaign without relying solely on the short-term military service of nobles. It also made his government expensive. Matthias fought in Bohemia and against Emperor Frederick III, occupying Moravia, Silesia, and Lusatia, and later taking Vienna and parts of Austria. He also acquired fortresses in Bosnia and strengthened defensive positions in the south, but he did not sustain his father’s policy of major offensives into Ottoman territory.

Matthias’s court was also a centre of artistic and scholarly patronage. Italian artists and architects worked on royal buildings at Buda and Visegrád, where Renaissance styles appeared alongside existing traditions. The king assembled the Bibliotheca Corviniana, a royal library of manuscripts, and supported scholars and artists. Such projects displayed the resources of the monarchy, even as the taxes that supported them and the army fell heavily on the population.

The Jagiellonian kings and the weakening of royal finances

Matthias died in 1490 without a legitimate son. The magnates supported Vladislaus II, king of Bohemia, in part because they expected a less forceful ruler. Vladislaus granted away much royal land and income in an effort to secure noble support. The crown’s finances weakened, while the Diet reduced the tax burden on the nobility. Matthias’s Black Army was not maintained; unpaid soldiers dispersed and some plundered the countryside before a royal force defeated them in 1492.

The same year, the Diet restricted serfs’ freedom of movement and expanded their obligations. Rural discontent grew, especially in a kingdom where cattle exports had brought prosperity to some peasants but did not prevent heavier demands on others. In 1514, peasants preparing for a crusade against the Ottomans rebelled under György Dózsa, a border-guard captain. The revolt spread to estates across the kingdom before magnates and lesser nobles joined to suppress it.

After the revolt, laws restricted peasant movement and imposed heavier obligations. István Werbőczy’s Tripartitum, completed in 1514 and printed in 1517, set out the kingdom’s customary law. It never became a formally promulgated statute, but gained great authority in legal practice. Its account of noble rights, property and procedure influenced courts for centuries.

Vladislaus’s son Louis II became king in 1516, while a royal council governed during his minority. The kingdom’s defences suffered from unpaid border guards and neglected fortresses. In 1521, Sultan Suleiman the Magnificent captured Belgrade, a key stronghold on the southern frontier. Louis and his advisers failed to restore the kingdom’s defensive capacity before the Ottoman advance resumed.

Mohács and the succession crisis

On 29 August 1526, the Hungarian army met Ottoman forces at Mohács. Reinforcements from Croatia and Transylvania did not arrive in time, and the Hungarian army was defeated. Louis II died after falling from his horse while fleeing the battlefield. The defeat exposed the consequences of weakened royal finances and an inadequate frontier defence, though it also followed a long history of mounting pressure from the Ottoman Empire.

After Louis’s death, rival groups of nobles elected John Zápolya and Ferdinand of Habsburg as kings. Each claimed the crown, opening a new struggle over the kingdom’s government and future. The battle at Mohács thus marked both the end of this period of medieval royal rule and the beginning of a succession crisis.
