On 10 November 1444, Murad II defeated the Hungarian, Polish and Wallachian armies under Władysław III of Poland ( also King of Hungary ) and János Hunyadi at the Battle of Varna, which was the final battle of the Crusade of Varna.

On the death of Hunyadi, Ladislaus made Ulrich governor of Hungary in October 1456 at the Diet of Futtak.

Serbia became a battleground between the Kingdom of Hungary and the Ottomans, and the angry Branković captured Hunyadi after his defeat at the Second Battle of Kosovo in 1448.

The main frame of the conflict with the Turks now resided in his jurisdiction and Hunyadi soon showed and displayed extraordinary capacity in marshalling its defenses with the limited resources at his disposal.

Hunyadi arrived at the siege of Nándorfehérvár at the end of 1455, after settling differences with his domestic enemies.

After his father's death in 1456, he was declared by his enemy Ulrich II of Celje ( now Captain General of Hungary with significant power ), responsible for the debts alleged to be owing by the elder Hunyadi to the state ; but he defended himself so ably at the diet of Futak ( October 1456 ) that Ulrich II of Celje feigned a reconciliation, promising to protect the Hunyadis on condition that they first surrendered all the royal castles entrusted to them.

The terrified young king, thereupon pardoned Hunyadi, and at a subsequent interview with his mother at Temesvár swore that he would protect the whole family.

On November 11, 1444, Murad defeated the Polish – Hungarian army of Wladislaus III of Poland led by Janos Hunyadi at the Battle of Varna.

Famous as a preacher, theologian, and inquisitor, he earned himself the nickname ' the Soldier Saint ' when in 1456 at age 70 he led a crusade against the invading Ottoman Empire at the siege of Belgrade with the Hungarian military commander John Hunyadi.

While Hunyadi's victory at Belgrade and the lasting legacy of his political decisions ( Vlad III the Impaler and Stephen III both came to power under Hunyadi, and he went to great lengths to have his son Matthias placed on the throne ) rendered the daunting Mehmed II far less of a threat to Christendom, his ultimate dream of a Christian reconquest of Constantinople would never be realized.

Hunyadi had chosen to stay out of the Siege of Constantinople because he was militarily unprepared to fight Mehmed's mighty army at the time, and instead opted to protect Hungary and fortify the Balkans.

The Second Battle of Kosovo ( Hungarian: második rigómezei csata, Turkish: İkinci Kosova savaşı ) ( 17 October – 20 October 1448 ) was fought at Kosovo Polje between a coalition of the Kingdom of Hungary and Wallachia led by John Hunyadi, against an Ottoman-led coalition under Sultan Murad II.

Hunyadi commanded the center of his army at the battle, while the Crusaders right wing was under the Wallachians.

A crusading army led by Regent John Hunyadi of Hungary was defeated by Sultan Murad II's forces at Kosovo Polje in 1448.

Branković also captured Hunyadi at Smederevo for a short time when he was going home from Kosovo in 1448.

The Eyalet was led by a vali ( governor ) or beylerbey ( sometimes with position of pasha or vizir ), whose residence was at the former Hunyadi Castle in Temeşvar.

Bogdan's son, Stephen, fled Moldavia together with his cousin, Vlad Dracula — who had sought protection at the Moldavian court – to Transylvania, at the court of Hunyadi.

In 1457, Ladislaus Hunyadi was captured with a trick and beheaded, while the king died suddenly in November that year ; rumors of poisoning were dispelled by research in 1985 which gave acute leukemia as the cause of death.

After the battle Hunyadi was captured by Brankovic, who didn't release him until a ransom of 100, 000 florins, the return of the domains that Hunyadi had revocated from Brankovic and the engagement of Hunyadi's heir to Brankovic's daughter were agreed upon.

The Hungarians had, however, to pay dearly for this victory, as plague broke out in the camp, from which John Hunyadi himself died three weeks later ( August 11, 1456 ).

* July 21 – July 22 – Battle of Nándorfehérvár ( Belgrade ): The Hungarians under John Hunyadi rout the Turkish army of Sultan Mehmed II.

Despite their alleged forthcoming help the Venetian fleet carried over the Turkish army from Asia into Europe and failed to sail to Varna, a surprising move that Władysław and his most senior military commander Hunyadi failed to anticipate.

In July 1442, an undaunted and intrepid Hunyadi proceeded march against the enemy with 15, 000 Hungarian and Szekler irregulars against a massed formation of a third Turkish invasion force reinforced by the choicest of Ottoman military numbering 80, 000 in Wallachia sent in retaliation for subsequent defeats.

On 21 July, Szilágyi's forces in the fortress repulsed a fierce assault by the Rumelian army, and Hunyadi pursued the retreating Ottoman forces into their camp, taking advantage of the Turkish army's confused flight from the city.

Other sets included the Austrian soldier ( Osztrák ), Turkish soldier ( Török ), William Tell ( Tell Vilmos ), and the Hunyadi series ( Hunyadi sorozat ).

Branković also imprisoned Hunyadi for a time in the dungeons of the fortress of Smederevo, but he was ransomed by his countrymen and, after resolving his differences with his powerful and numerous political enemies in Hungary, led a punitive expedition against the Serbian prince, who was forced to accept harsh terms of peace.

Christendom found its champion in John Hunyadi who gained a series of victories over the Ottomans after 1441.

In 1456 after the death of his rival John Hunyadi, Ulrich II succeeded him as Captain General of Hungary.

At the end of 1455, after a public reconciliation with all his enemies, Hunyadi began preparations.

At the end of the negotiations, Hunyadi had threatened to kill Brankovic in person after his country was occupied.

After 1450 Tokaj was the property of the Hunyadi family, so after Matthias Hunyadi became king, the town became a royal estate.

The Counts of Celje, raised to immediate Reichsgrafen in 1436, became extinct when Count Ulrich II was killed by the liegemen of László Hunyadi in 1456, after which the Habsburg emperor Frederick III, also Duke of Carinthia, seized his territory.

The Second Battle of Kosovo in 1448 had ended with the defeat of John Hunyadi, voivode of Transylvania after Skanderbeg and his forces did not arrive to provide the help Hunyadi had counted on.

Tourists are told that it was the place where Vlad III of Wallachia ( commonly known as Vlad the Impaler ) was held prisoner by János Hunyadi, Hungary's military leader and regent during the King's minority, for 7 years after Vlad was deposed in 1462.

However, after Branković's dealings with the Turks was discovered in 1455 ( leading among other things to Hunyadi's defeat at the battle of Kosovo ), his estates were confiscated and placed under the stewardship of Hunyadi ( who was acting regent at the time ).
