Louis II of Hungary

When Ulaszlo II dies in 1516, his ten-year-old son Louis II (1516-26) becomes king, but a royal council appointed by the Diet rules the country.

Hungary is in a state of near anarchy under the magnates' rule.

The king's finances are a shambles; he borrows to meet his household expenses despite the fact that they total about one-third of the national income.

The country's defenses sag as border guards go unpaid, fortresses fall into disrepair, and initiatives to increase taxes to reinforce defenses are stifled.

In 1521 Sultan Suleiman the Magnificent recognizes Hungary's weakness and seizes Belgrade in preparation for an attack on Hungary.

In August 1526, he marches more than one hundred thousand troops into Hungary's heartland, and at Mohacs they cut down all but several hundred of the twenty-five thousand ill-equipped soldiers whom Louis II had been able to muster for the country's defense.

Louis himself dies, thrown from a horse into a bog. 

Ferdinand, in addition to the lands he receives from his brother, also increases his territorial reach by marrying into the Jagiellon family, the royal family of Hungary and Bohemia.

When his brother-in-law, King Louis, dies fighting the Turks at the Battle of Mohacs in 1526, Ferdinand claims the right of succession.

Although the diets representing the nobility of Bohemia (and its dependencies of Moravia and Silesia) do not acknowledge Ferdinand's hereditary rights, they formally elect him king of Bohemia.

As king of Bohemia, he also becomes an elector-prince of the Holy Roman Empire.

In Hungary and in the subordinate Kingdom of Croatia-Slavonia-Dalmatia, however, Ferdinand faces the rival claim of a Hungarian nobleman and the reality of the Turkish conquest of the country.

He is able to assert authority only over the northern and western edges of the country, which becomes known as Royal Hungary.

His Hungarian rival becomes a vassal of the Turks, ruling over Transylvania in eastern Hungary.

The rest of Hungary will become part of the Ottoman Empire in 1603.

Although Ferdinand undertakes various administrative reforms in order to centralize authority and increase his power, no meaningful integration of the Hereditary Lands and the two newly acquired kingdoms occurs.

In contrast to the authority of kings of Western Europe, where feudal structures are already in decline, Ferdinand's authority continues to rest on the consent of the nobles as expressed in the local diets, which successfully resist administrative centralization.

Upon the death of the Hussite king, the Bohemian estates elect a Polish prince, Vladislav II, as king.

In 1490 Vladislav also becomes king of Hungary, and the Polish Jagellonian line rules both Bohemia and Hungary.

The Jagellonians govern Bohemia as absentee monarchs; their influence in the kingdom is minimal, and effective government falls to the regional nobility.

Czech Catholics accepts the Compact of Basel in 1485 and are reconciled with the Utraquists.

Vladislav's son, King Louis, is decisively defeated by the Ottomans at Mohacs in 1526 and subsequently dies.

As a result, the Turks conquer part of the Kingdom of Hungary; the rest (including Slovakia) comes under Habsburg rule.

The Bohemian estates elect Archduke Ferdinand, younger brother of Emperor Charles V, to succeed Louis as king of Bohemia.

Thus begins almost three centuries of Habsburg rule for both Bohemia and Slovakia.

The Bohemian Kingdom had in several instances had the possibility of becoming a Czech national monarchy.

The failure to establish a native dynasty, however, had prevented such an outcome and left the fate of the Bohemian Kingdom to dynastic politics and foreign rulers.

Although the Bohemian Kingdom evolves neither into a national monarchy nor into a Czech nation-state, the memory of it serves as a source of inspiration and pride for modern Czech nationalists.

East Central Europe (1504–1515 CE): Jagiellonian-Habsburg Rivalry, Ottoman Encroachment, and Dynastic Alliances

From 1504 to 1515 CE, East Central Europe experienced intense geopolitical shifts driven by escalating rivalry between the Jagiellonian dynasty (in Hungary, Bohemia, and Poland-Lithuania) and the ascendant Habsburg dynasty, as well as growing Ottoman pressures from the south. Diplomatic realignments, including strategic dynastic marriages, reshaped alliances, setting the stage for future Habsburg dominance and enduring regional tensions.

Political and Military Developments

Jagiellonian Rule and Internal Struggles

• Under Vladislaus II Jagiellon (r. 1490–1516), Hungary and Bohemia increasingly faced internal aristocratic conflicts and weakening royal authority. Vladislaus’s ineffective governance led to greater political fragmentation and noble autonomy.

• Poland-Lithuania, ruled by Sigismund I the Old (r. 1506–1548), faced continued threats from the Teutonic Order and Moldavia, prompting intensified military and diplomatic efforts to secure eastern and northern frontiers.

Escalation of Jagiellonian-Habsburg Rivalry

• Habsburg Emperor Maximilian I (r. 1493–1519) pursued an aggressive strategy to assert dominance over Hungarian and Bohemian territories, heightening rivalry with the Jagiellonians.

• Diplomatic tensions culminated in the First Congress of Vienna (1515), resulting in strategic marriages between the Jagiellonian and Habsburg houses, profoundly influencing future dynastic successions. The treaties at this congress arranged double marriages: Vladislaus’s children, Louis II of Hungary and Bohemia, and Anne Jagiellon, married into the Habsburg dynasty, profoundly reshaping regional alliances.

Increasing Ottoman Threats to Hungary

• The Ottoman Empire, under Sultan Selim I (r. 1512–1520), intensified its incursions into southern Hungarian territories, significantly straining Hungary’s resources and defenses. Frequent Ottoman raids prompted increased military expenditures and defensive strategies.

Economic and Technological Developments

Continued Urban Prosperity and Trade

• Economic vitality persisted, particularly within Hanseatic cities (Gdańsk, Toruń, Elbląg, Stettin) and urban centers such as Prague, Kraków, Vienna, and Buda, driven by strong commercial networks trading grain, textiles, metals, and luxury goods.

• Increased artisanal productivity and expanding mercantile activities significantly enhanced regional economic stability and urban wealth.

Mining and Metallurgical Growth

• Notably in Hungarian and Slovak mining centers (Banská Štiavnica, Banská Bystrica, Kremnica), robust extraction of precious metals (gold, silver, copper) continued, significantly contributing to regional prosperity and enhancing Hungary’s economic influence.

Cultural and Artistic Developments

Renaissance Flourishing under Jagiellonian and Habsburg Patronage

• Hungarian Renaissance culture thrived under Vladislaus II, who continued fostering intellectual, artistic, and architectural developments, especially in Buda and Esztergom, further enhancing Hungary’s cultural prestige.

• Polish cities, notably Kraków under Sigismund I, experienced significant Renaissance cultural patronage, reflected in humanist scholarship, artistic achievements, and architectural innovations.

Bohemian Artistic Continuity

• Bohemian culture continued blending Gothic and emerging Renaissance influences, particularly in Prague, where royal patronage sustained artistic and architectural projects, despite Vladislaus’s largely absent governance.

Settlement and Urban Development

Defensive Urban Fortification

• Persistent Ottoman threats and regional conflicts led to enhanced urban fortifications across Hungary, notably Buda, Pest, Székesfehérvár, and along frontier regions, significantly shaping urban development and military infrastructure.

Expansion and Urbanization in Poland and Bohemia

• Urban centers like Kraków, Lublin, and Prague continued to expand and prosper, driven by robust trade, artisanal activities, and growing populations, reflecting stable urban economies and effective civic governance.

Social and Religious Developments

Nobility’s Growing Power and Influence

• Aristocratic power significantly expanded, particularly in Hungary, Bohemia, and Poland-Lithuania. Noble diets, notably the Hungarian Diet and Polish Sejm, increasingly dominated royal decision-making, fiscal policy, and regional governance.

• Nobility’s rising influence contributed to weakened royal authority, internal divisions, and more decentralized governance structures, profoundly shaping regional political dynamics.

Religious Stability and Ecclesiastical Influence

• The Catholic Church remained influential across East Central Europe, promoting ecclesiastical scholarship, education, and artistic patronage, reinforcing cultural cohesion. Monastic and ecclesiastical institutions notably influenced education, religious practices, and social norms.

Long-Term Consequences and Historical Significance

The era 1504–1515 CE proved pivotal for East Central Europe, significantly reshaped by escalating Jagiellonian-Habsburg rivalry, strategic dynastic marriages from the Congress of Vienna (1515), and intensified Ottoman threats. Diplomatic alliances secured at Vienna laid foundations for eventual Habsburg dominance in Bohemia and Hungary, significantly influencing Central European geopolitics throughout the 16th century. Continued economic vitality and cultural flourishing under Renaissance patronage strengthened regional prosperity, despite rising external threats and internal divisions. These developments profoundly influenced East Central Europe’s trajectory, establishing political and cultural patterns that endured through the early modern period.

Maximilian, in order to reduce the growing pressures on the Empire brought about by treaties between the rulers of France, Poland, Hungary, Bohemia, and Russia, as well as to secure Bohemia and Hungary for the Habsburgs, meets with the Jagiellonian kings Ladislaus II of Hungary and Bohemia and Sigismund I of Poland at the First Congress of Vienna on July 22, 1515.

Here they arrange for Maximilian's granddaughter Mary to marry Louis, the son of Ladislaus, and for Anne (the sister of Louis) to marry Maximilian's grandson Ferdinand (both grandchildren being the children of Philip the Handsome, Maximilian's son, and Joanna of Castile.

The broad coalition against Lithuania and Poland ceases, but the war between the Grand Duchy of Lithuania and Grand Duchy of Moscow will last until 1520.

East Central Europe (1516–1527 CE): Ottoman Conquest of Hungary, End of the Jagiellonians, and Rise of Habsburg Dominance

Between 1516 and 1527 CE, East Central Europe experienced dramatic geopolitical changes marked by the collapse of Jagiellonian power in Hungary and Bohemia, the devastating Battle of Mohács (1526), and the decisive expansion of Habsburg authority into the region. This era witnessed the irreversible transformation of Hungary’s medieval kingdom, significant shifts in regional alliances, and increasing Ottoman dominance, profoundly reshaping East Central Europe's political landscape.

Political and Military Developments

End of Jagiellonian Rule and the Battle of Mohács (1526)

• Following the death of Vladislaus II Jagiellon in 1516, his young son Louis II ascended the thrones of Hungary and Bohemia, inheriting weakened royal authority and an unstable kingdom.

• On 29 August 1526, Hungarian forces suffered catastrophic defeat at the Battle of Mohács against Ottoman Sultan Suleiman the Magnificent (r. 1520–1566). Louis II was killed, leading to Hungary's political fragmentation and subsequent partition.

Fragmentation of Hungary and Ottoman Occupation

• The aftermath of Mohács shattered the medieval Kingdom of Hungary, partitioning it into three parts:

  • Royal Hungary under Habsburg control in the north and west (including parts of modern Slovakia, western Hungary, and Croatia).

  • Ottoman Hungary (central and southern regions), directly administered by the Ottomans.

  • Principality of Transylvania in the east, a semi-autonomous entity under Ottoman suzerainty, governed by Hungarian princes.

• These divisions significantly reshaped Hungary’s political and cultural identity for centuries.

Rise of Habsburg Dominance in Bohemia and Hungary

• Following Mohács, Ferdinand I of Habsburg (brother of Emperor Charles V and husband of Louis II's sister, Anne Jagiellon) asserted dynastic claims, being crowned King of Bohemia in 1526, and subsequently as King of Hungary in 1527 at Székesfehérvár.

• Ferdinand’s accession marked a fundamental shift toward long-term Habsburg rule, effectively ending Jagiellonian influence in these key Central European kingdoms.

Polish-Lithuanian Stability under Sigismund I

• Poland-Lithuania, ruled by Sigismund I the Old (1506–1548), maintained relative stability, successfully repelling external threats, notably from Muscovy and Crimean Tatars, reinforcing Poland’s eastern borders.

Economic and Technological Developments

Economic Disruption and Regional Reorientation

• Hungary’s partition severely disrupted traditional economic networks, prompting substantial commercial realignments. Trade shifted northward toward Bohemia, Poland-Lithuania, and the Habsburg lands, notably benefiting Vienna, Prague, Kraków, and the northern Hanseatic cities (Gdańsk, Toruń, Elbląg).

• The collapse of Hungarian control of key southern trade routes to the Balkans and Mediterranean significantly reshaped regional commerce, redirecting flows through safer northern routes.

Cultural and Artistic Developments

Impact of Ottoman Occupation on Hungarian Culture

• Ottoman occupation deeply impacted Hungarian culture, introducing Islamic and Ottoman architectural and artistic styles in occupied regions, notably in southern Hungarian towns and fortresses.

• Conversely, regions under Habsburg influence experienced increased cultural alignment with Renaissance Vienna, fostering intensified artistic and intellectual exchanges.

Bohemian and Polish Renaissance Flourishing

• Bohemia under Ferdinand I and Poland under Sigismund I continued experiencing Renaissance cultural prosperity. Prague and Kraków emerged as prominent cultural centers, promoting humanist scholarship, architectural innovation, and literary production, strongly influenced by Italian and German Renaissance trends.

Settlement and Urban Development

Urban Fortification and Military Infrastructure

• Cities throughout East Central Europe, particularly along new Ottoman borders (e.g., Vienna, Győr, Esztergom), significantly reinforced defensive infrastructure, reflecting heightened military threats.

• Kraków, Prague, and major Hanseatic cities continued prospering economically and expanding urban fortifications to secure trade routes against disruptions and regional instability.

Social and Religious Developments

Increased Noble Autonomy and Feudal Fragmentation

• The collapse of centralized Hungarian royal authority accelerated noble autonomy, particularly in Ottoman Hungary and Transylvania. Local magnates increasingly dominated regional governance, fostering decentralized and feudalized political structures.

• Polish and Bohemian aristocratic diets maintained significant influence, balancing noble privileges against royal authority, reflecting stable yet decentralized governance patterns.

Religious Resilience and Ecclesiastical Influence

• The Catholic Church faced significant challenges in Ottoman-occupied regions but maintained strong influence in Habsburg-controlled Bohemia and Royal Hungary, actively supporting religious education, monastic patronage, and ecclesiastical arts.

• Emerging Protestant Reformation ideas began influencing East Central Europe, notably among urban elites and nobility in Bohemia, Poland, and Royal Hungary, foreshadowing future religious conflicts.

Long-Term Consequences and Historical Significance

The era 1516–1527 CE marked a watershed moment in East Central Europe's historical trajectory, defined by Hungary's devastating defeat at Mohács and the subsequent rise of Habsburg rule. The partition of Hungary profoundly transformed regional geopolitics, embedding long-lasting divisions that endured for centuries. Increased Ottoman threats reshaped military priorities and economic networks, while the Jagiellonian dynasty’s collapse fundamentally realigned political alliances. Concurrently, Polish and Bohemian cultural flourishing continued, reinforcing distinct national identities and intellectual traditions. These complex transformations critically shaped East Central Europe's subsequent development, decisively influencing regional dynamics into the early modern era.

The absolutist king Matthias Corvinus, son of John Hunyadh, was the last strong king of medieval Hungary.

His election was the first time that a member of the nobility mounted to the Hungarian royal throne without dynastic background.

A successful military leader and an enlightened patron of the arts and learning, his library, the Bibliotheca Corviniana, was Europe's greatest collection of historical chronicles, philosophic and scientific works in the fifteenth century, and second only in size to the Vatican Library.

The library is a UNESCO World Heritage Site.

The serfs and common people considered him a just ruler because he protected them from excessive demands from and other abuses by the magnates.

Under his rule, in 1479, the Hungarian army destroyed the Ottoman and Wallachian troops at the Battle of Breadfield.

Abroad he defeated the Polish and German imperial armies of Frederick at Breslau (Wrocław).

Matthias' mercenary standing army, the Black Army of Hungary, was an unusually large army for its time, and it conquered parts of Austria, Vienna (1485) and parts of Bohemia.

King Matthias died in 1490 without lawful sons, and the Hungarian magnates had procured the accession of the Pole Vladislaus II as King of Bohemia and Hungary, supposedly because of his weak influence on Hungarian aristocracy.

He is known as King Dobře, or Dobzse in Hungarian orthography (meaning "good" or, loosely, "OK") from his habit of accepting, without question, every petition and document laid before him.

The freshly elected King Vladislaus II had donated most of the royal estates, régales and royalties to the nobility.

By this method, the king had tried to stabilize his new reign and preserve his popularity among the magnates.

After the naive fiscal and land policy of the royal court, the central power had begun to experience severe financial difficulties, largely due to the enlargement of feudal lands at his expense.

The noble estate of the parliament had succeeded in reducing the tax burden by seventy to eighty percent, at the expense of the country's ability to defend itself.

Vladislaus has become the magnates' helpless "prisoner"; he can make no decision without their consent.

The Black Army had been dissolved in 1494 by the aristocracy.

The magnates had also dismantled the national administration systems and bureaucracy throughout the country.

The country's defenses sag as border guards and castle garrisons go unpaid, fortresses fall into disrepair, and initiatives to increase taxes to reinforce defenses are stifled.

Hungary's international role has declined, its political stability shaken, and social progress is deadlocked.

In 1514, the weakened and aging Vladislaus had faced a major peasant rebellion led by György Dózsa, which had been ruthlessly crushed by the nobles.

The Hungarians are no longer a politically united people; the resulting degradation of order has paved the way for Ottoman preeminence.

George of Brandenburg was born in Ansbach, the third of eight sons of Margrave Frederick the Elder and his wife Sophia of Poland, daughter of Casimir IV of Poland and Elisabeth of Habsburg.

Through his mother, he is related to the royal court in Buda.

He had entered the service of his uncle, King Vladislaus II, living at his court from 1506.

The king had received him as an adopted son, entrusted him in 1515 with the Duchy of Oppeln, and in 1516 makes him member of the tutelary government instituted for Hungary, and tutor of his son Lajos, or Louis, by his third wife, Anne of Foix-Candale.

Louis’s paternal grandfather was Casimir IV of Poland.

His son had been previously crowned as King of Hungary in 1508 and on March 3, 1509 as King of Bohemia in the St. Vitus Cathedral in Prague, so the succession is assured.

Vladislaus has called Tamás Bakócz, John Bornemissza and George of Brandenburg, and named them the bearers and custodians of the young prince Louis.

Vladislaus dies on March 13, 1516, two weeks after his sixtieth birthday, in the city of Buda.

His funeral is held six days after that in the city of Székesfehérvár's main cathedral, where all the Kings of Hungary are customarily buried.

The monarch leaves a kingdom in political ruins and with a debt of four hundred and three thousand Hungarian florins.

Archduchess Mary of Austria, becomes queen of Hungary and Bohemia on the death of her father-in-law in 1516.

Born in Brussels on September 15, 1505, between ten and eleven in the morning, Mary was the fifth child of King Philip I and Queen Joanna of Castile.

Her birth was very difficult; the Queen's life was in danger and it took her a month to recover.

On September 20, she was baptized by Nicolas Le Ruistre, Bishop of Arras, and named after her paternal grandmother, Mary of Burgundy, who had died in 1482.

Her godfather is her paternal grandfather, Holy Roman Emperor Maximilian I, who had promised, on March 17, 1506, to marry her to the first son born to King Vladislaus II of Hungary.

At the same time, the two monarchs decided that a brother of Mary would marry Vladislaus' daughter Anne.

Three months later, Vladislaus' wife, Anne of Foix-Candale, gave birth to a son, Louis Jagiellon.

Queen Anne died in childbirth and the royal physicians made great efforts to keep the sickly Louis alive.

After the death of Mary's father in September 1506, her mother's mental health had begun to deteriorate.

Mary, along with her brother, Archduke Charles, and her sisters, Archduchesses Eleanor and Isabella, had been put into the care of her paternal aunt, Archduchess Margaret, while two other siblings, Archduke Ferdinand and posthumously born Archduchess Catherine, remained in Castile.

Mary, Isabella, and Eleanor had been educated together at their aunt's court in Mechelen.

Their music teacher was Henry Bredemers.

Mary had been summoned to the court of her grandfather Maximilian in 1514.

On July 22, 1515, Mary and Louis had been married in St. Stephen's Cathedral, Vienna.

At the same time, Louis' sister Anne had been betrothed to an as yet unspecified brother of Mary, with Emperor Maximilian acting as proxy.

Due to their age, it was decided that the newly married couple would not live together for a few more years.

Anne had eventually married Mary's brother Ferdinand and had come to Vienna, where the double sisters-in-law are educated together until 1516, when the death of Mary's father-in-law makes Louis and Mary king and queen of Hungary and Bohemia.

Mary moves to Innsbruck, where she will be educated until 1521.

Maximilian encourages her interest in hunting, while childhood lessons prompt an interest in music.

This passion will later be demonstrated during her tenure as governor of the Netherlands.

Maximilian, Holy Roman Emperor from 1493, has sought to extend his sphere of influence through his own marriages and those of his descendants (attempted unsuccessfully and successfully alike), as is current practice for dynastic states at this time.

The marriages he had arranged for both of his children had more successfully fulfilled the specific goal of thwarting French interests, and after the turn of the sixteenth century, his matchmaking had focused on his grandchildren, for whom he had looked away from France towards the east.

These political marriages are summed up in the following Latin elegiac couplet: Bella gerant aliī, tū fēlix Austria nūbe/ Nam quae Mars aliīs, dat tibi regna Venus, "Let others wage war, but thou, O happy Austria, marry; for those kingdoms which Mars gives to others, Venus gives to thee.”

Maximilian had appointed his daughter Margaret as both Regent of the Netherlands and the guardian and educator of his grandsons Charles and Ferdinand (their father, Philip, having predeceased Maximilian), and she has fulfilled this task well.

Through wars and marriages he has extended the Habsburg influence in every direction: to the Netherlands, Spain, Bohemia, Hungary, Poland, and Italy.

This influence will last for centuries and shape much of European history.

After it became clear that Maximilian's policies in Italy had been unsuccessful, and after 1517 Venice reconquered the last pieces of their territory from Maximilian, the emperor has now started to focus entirely on the question of his succession.

His goal is to secure the throne for a member of his house and prevent Francis I of France from gaining the throne; the resulting "election campaign" is unprecedented due to the massive use of bribery.

The Fugger family has provided Maximilian a credit of one million gulden, which has been used to bribe the prince-electors.

At first, this policy seemed successful, and Maximilian had managed to secure the votes from Mainz, Cologne, Brandenburg and Bohemia for his grandson Charles V.

The death of Maximilian on January 2, 1519, seems to put the succession at risk, but in a few months the election of Charles V will be secured.

Hungary’s sickly and frivolous King Louis II, on ascending to the thrones of Hungary and Bohemia, had been adopted by Holy Roman Emperor Maximilian I.

When Maximilian died in 1519, Louis had been raised by his legal guardian, his cousin George of Brandenburg.

Louis is declared of age in 1521, but remains under control of the Hungarian magnates.

At the Hungarian court there are two parties arrayed against each other: the Magyar party under the leadership of John Zápolya, Voivode of Transylvania, and the German party under the leadership of George of Brandenburg, whose authority has been increased by the acquisition of the duchies of Ratibor and Oppeln by hereditary treaties with their respective dukes and of the territories of Oderberg, Beuthen, and Tarnowitz as pledges from the king, who cannot redeem his debts.

George makes made an arrangement with Petar Keglević, who is captain of Jajce, in 1521 and pulls back from Hungary and Croatia; this arrangement, which will be accepted by Louis II in 1526, will not be not accepted by Holy Roman Emperor Ferdinand I until 1559.

The Hungarians have long opposed Ottoman expansion in southeastern Europe, but the fall of Nándorfehérvár (present-day Belgrade, Serbia) and Szabács (now Šabac, Serbia) in 1521 means that most of southern Hungary is left indefensible.

The strongest nobles are so busy oppressing the peasants and quarreling with the gentry class in the parliament that they fail to heed the agonized calls of King Louis against the Turks.
