The king's power remains paramount in Hungary until the end of the twelfth century.

He is the largest landowner, and income from the crown lands nearly equals the revenues generated  from mines, customs, tolls, and the mint.

In the thirteenth century, however, the social structure changes, and the crown's absolute power begins to wane.

As the crown lands become a less important source of royal revenues, the king finds it expedient to make land grants to nobles to ensure their loyalty.

King Andrew II (1205-35), a profligate spender on foreign military adventures and domestic luxury, makes huge land grants to nobles who fight for him.

These nobles, many of whom are foreign knights, soon make up a class of magnates whose wealth and power far outstrip that of the more numerous, and predominantly Magyar, lesser nobles.

When Andrew tries to meet burgeoning expenses by raising the serfs' taxes, thereby indirectly slashing the lesser nobles' incomes, the lesser nobles rebels.

In 1222 they force Andrew to sign the Golden Bull, which limits the king's power, declares the lesser nobles (all free men not included among the great Barons or magnates) legally equal to the magnates, and gives them the right to resist the king's illegal acts.

The lesser nobles also begin to present Andrew with grievances, a practice that evolves into the institution of the parliament, or Diet.

Andrew II's son Béla IV (1235-79) tries with little success to reestablish royal preeminence by reacquiring lost crown lands.

His efforts, however, create a deep rift between the crown and the magnates just as the Mongols are sweeping westward across Russia toward Europe.

Aware of the danger, Béla orders the magnates and lesser nobles to mobilize.

Few respond, and the Mongols rout Béla's army at Mohi on April 11, 1241.

Béla flees first to Austria, where Duke Frederick of Babenberg holds him for ransom, then to Dalmatia.

The Mongols reduce Hungary's towns and villages to ashes and slaughter half the population before news arrives in 1242 that the Great Khan Ögedei has died in Karakorum.

The Mongols withdraw, sparing Béla and what remains of his kingdom.

Prince Vladimir II Yaroslavich of Halych, who had been dethroned by his boyars, seeks refuge in the court of Béla III in 1188.

Béla leads his armies against Halych and occupies it, but afterwards he grants the principality to his second son, Andrew and has prince Vladimir arrested.

Béla had on May 31, 1189, welcomed Frederick I, who is making his Crusade to the Holy Land, and on the emperor's request he had set free his brother, Géza, who then departed for Constantinople.

Afterwards, when Emperor Frederick I enters into a controversy with Emperor Isaac II, Béla mediates between them.

However, in the meantime, Prince Vladimir II escapes from Hungary and reoccupies his principality.

East Central Europe (1192–1203 CE): Přemyslid Restoration under Ottokar I, Emergence of Andrew II in Hungary, Continued Polish Decentralization, and Austria’s Ascendant Babenberg Dynasty

Between 1192 and 1203 CE, East Central Europe—including modern-day Poland, Czechia, Slovakia, Hungary, and eastern regions of Germany and Austria east of 10°E and north of the defined southeastern boundary—experienced critical political transitions, dynastic realignments, and continued territorial consolidation. Bohemia saw renewed Přemyslid strength under Ottokar I, Hungary navigated succession struggles leading toward the ascendancy of Andrew II, Poland remained politically fragmented with strong regional principalities, and Austria continued its growth and stabilization under the prominent Babenberg dynasty. This era was pivotal in establishing lasting political frameworks, economic prosperity, and enduring cultural traditions across the region.

Political and Military Developments

Přemyslid Restoration under Ottokar I in Bohemia

• In 1197, Ottokar I Přemysl (r. 1197–1230) secured power, bringing renewed stability and reinvigorating Přemyslid authority after prolonged dynastic strife. His effective governance restored Bohemia’s regional influence and solidified its alliance with the Holy Roman Empire.

• Ottokar’s political acumen laid foundations for future Bohemian royal autonomy, leading eventually to his hereditary royal title recognition in 1198 by Philip of Swabia, bolstering the Přemyslid dynasty’s long-term prominence.

Hungarian Succession Struggles and Rise of Andrew II

• Hungary entered a period of complex succession disputes after Béla III’s death (1196). His sons, Emeric (1196–1204) and Andrew II (1205–1235), contended for power, causing brief internal instability.

• Emeric, ruling from 1196, attempted to stabilize royal power but faced challenges from his ambitious younger brother Andrew, whose eventual ascendancy in the following era (1205) would profoundly impact Hungarian politics.

Persistent Polish Decentralization and Regional Autonomy

• Poland continued its fragmented political landscape, divided among powerful Piast principalities such as Silesia under Duke Henry I the Bearded, Greater Poland, Masovia, and Lesser Poland. Rivalry among these territories persisted, further decentralizing political authority and strengthening local aristocratic rule.

King Emeric's five-year-old son, crowned on August 26, 1204, while his dying father was still alive, had in June 1205 upon his father's death of acceded to the Hungarian throne as Ladislaus III.

With the coronation, Emeric had wanted to ensure his son's succession to the throne.

Emeric had made his brother, Duke Andrew, who had rebelled against the king several times, promise that he would protect the child and help him in the governance until he became an adult.

Andrew, promising this, had been released from prison and is appointed as regent during the minority of his nephew.

The following year Andrew deposes Ladislaus and takes the throne as Andrew II.

The Dowager Queen, Constance of Aragon, escapes with her son to Vienna to Leopold VI, Duke of Austria, but Ladislaus soon dies there on May 7.

The former Regent and now King Andrew II of Hungary takes the body of his nephew and buries him in the Royal Crypt of Székesfehérvár.

Duke Leopold sends Constance back to Aragon.

The first German colonists (the future Transylvanian Saxon community) arrive in Transylvania, following grants by Andrew II of Hungary.

The Teutonic Knights, under the leadership of the grand master Hermann von Salza, begin transferring their main center of activity from the Holy Land to eastern Europe.

The order's first European enterprise starts in Hungary in 1211, when King Andrew II invites a group of the Teutonic Knights to protect his Transylvanian borderland against the Cumans by colonizing it and by converting its people to Christianity.

The Knights establish Kronstadt (modern Brasov), a city in the region of present central Romania on the northern slope of the Transylvanian Alps, in 1211.

East Central Europe (1216–1227 CE): Golden Bull of Hungary, Bohemian Consolidation, Polish Regional Rivalries, and Babenberg Influence in Austria
