The '''siege of Belgrade''', or '''siege of Nándorfehérvár''' ({{langx|hu|Nándorfehérvár ostroma}} or {{lang|hu|nándorfehérvári diadal}}, {{lit}} "Triumph of Nándorfehérvár"; {{lang-sr-Cyrl|Опсада Београда|Opsada Beograda}}) was a military [[blockade]] of [[Belgrade]] that occurred 4–22 July 1456 in the aftermath of the [[fall of Constantinople]] in 1453 marking the Ottomans' attempts to expand further into Europe. Led by Sultan [[Mehmed II]], the Ottoman forces sought to capture the strategic city of Belgrade ({{langx|hu|Nándorfehérvár|link=no}}), which was then under [[Kingdom of Hungary (1301–1526)|Hungarian]] control and was crucial for maintaining control over the Danube River and the Balkans.

The Hungarian defenders, under the leadership of [[John Hunyadi]], who had garrisoned and strengthened the fortress city at his own expense, put up a determined resistance against the larger Ottoman army. The siege lasted for several weeks, during which both sides suffered heavy losses. The defenders used innovative tactics, including the use of heavy artillery and firearms, to repel the Ottoman assaults. Hunyadi's relief force destroyed a Turkish flotilla on 14 July 1456 before repulsing their large scale assault to capture the city on 21 July. Wounded Mehmed II was compelled to lift the siege and retreat on 22 July 1456. This victory boosted the morale of European Christian forces and was seen as a turning point in their efforts as it provided a crucial buffer and temporarily halted [[Ottoman wars in Europe|Ottoman expansion]] in Europe.

John Hunyadi's successful defence of Belgrade earned him widespread acclaim and respect as a military leader though he died of the plague a few weeks later. The Ottomans would continue their expansion in other directions, and the struggle between the Ottoman Empire and European powers persisted for centuries. The battle's significance also extended beyond its immediate aftermath, as it demonstrated the importance of firearms and artillery in warfare, heralding a new era in military technology and tactics.

The Ottoman Empire, under the leadership of Sultan Mehmed II, had recently achieved a significant victory by capturing Constantinople in 1453, making it the new capital of the Ottoman Empire, thereby ending the Byzantine Empire.<ref name="Rogers Caferro Reid 2010 p. 2-PA45">{{cite book |last1=Rogers |first1=C.J. |url=https://books.google.com/books?id=mzwpq6bLHhMC&pg=RA2-PA45 |title=The Oxford Encyclopedia of Medieval Warfare and Military Technology |last2=Caferro |first2=W. |last3=Reid |first3=S. |publisher=Oxford University Press |year=2010 |isbn=978-0-19-533403-6 |page=2-PA45 |issue=v. 1}}</ref> The Ottomans became more ambitious in their expansionist aims, seeking to extend their influence further into Europe. They considered Belgrade, a strategically positioned fortress city at the confluence of the Danube and Sava river, as a crucial gateway for their advance northward. The Ottoman Empire's expansionist ambitions posed a significant challenge to the stability and security of European states, leading to a united effort to resist further Ottoman encroachment.<ref name="Rogers Caferro Reid 2010 p. 2-PA45" /> In 1452 former ''gubernátor'' [[John Hunyadi]] surrendered the regency to King [[Ladislas V]], who came of age, and became Count of [[Beszterce-Naszód County|Besztercze]] and captain general of Hungary.<ref name="Tucker 2009 p. 399">{{cite book |last=Tucker |first=S.C. |url=https://books.google.com/books?id=h5_tSnygvbIC&pg=PR3 |title=A Global Chronology of Conflict: From the Ancient World to the Modern Middle East [6 volumes]: From the Ancient World to the Modern Middle East |publisher=ABC-CLIO |year=2009 |isbn=978-1-85109-672-5}}</ref>

After conducting [[Mehmed II#Conquest of Serbia (1454–1459)|two campaigns]] against the [[Serbian Despotate]] in 1454 and 1455, Sultan Mehmed decided to continue his conquests towards the northwest by capturing the strategically important city of Belgrade from the [[Kingdom of Hungary (1301–1526)|Kingdom of Hungary]]. Significant preparations were made by the Ottoman sultan for the conquest of the city, including the casting of 22 large cannons alongside many smaller ones and the establishment of a navy that would sail up the Danube to assist the army during the siege.<ref name=":0">{{Cite journal |last=Türkmen |first=İlhan |date=5 January 2015 |title=The Campaigns Against Serbia During the Reign of Mehmed the Conqueror per Ottoman Chronicles |journal=Asia Minor Studies - International Journal of Social Sciences |volume=3 |issue=5 |pages=115–132 |quote=Fatih Belgrad’ı alabilmek için esaslı bir hazırlık yapmıştır. Morava nehri üzerindeki Krusevaç’ta toplar döktürüp bunları Tuna nehri kanalıyla Hırsova’ya yollamıştır ve burada Rumeli Beylerbeyi Dayı Karaca Paşa’ya teslim edilmiştir. Binlerce işçinin çalıştığı bu top dökümhanelerinde yapılan toplar arasında boyları 27 ayak olan 22 büyük top bulunmaktadır. Ayrıca iki yüz çektirmeden oluşan bir ince donanma su yoluyla gelebilecek yardımları engellemek maksadıyla Vidin’den Tuna’ya çıkmıştır... Ümitsizliğin arttığı bu sırada Hunyadi komutasında Tuna’nın öte yakasından bir Macar ordusunun toplandığı haberi gelmiştir... Bu gelişme üzerine Fatih gerekli tedbirleri görüşmek üzere harp meclisini toplamıştır. Mecliste Karaca Bey; bir kısım Osmanlı askerî gücünün Tuna’nın öbür yakasına Padişah geçmese bile kendisi ile gönderilmesi gerektiğini arz etmiştir. Bu suretle Macar güçleri ile Belgrad arasına Osmanlı askerî güçleri girmiş olacaktır. Böylece iki taraf arasındaki irtibat koparılmak istenmiştir. Fakat Karaca Paşa’nın mecliste ortaya attığı bu fikir diğer kumandanlar tarafından uygun görülmemiştir... Fakat şurası bir gerçek ki Karaca Paşa’nın teklifi reddedilmiştir. Burada Fatih’in düşman Tuna’nın öte yakasına gelmiş iken ve bunca askerlik tecrübesine rağmen bu fikre katılmaması da izahı zor bir konudur. Belki Padişah düşman kuvvetlerinin Tuna’nın beri tarafına geçebileceklerine ihtimal vermemiş veya Türk donanmasının bunu durdurabileceğini düşünmüştür... Fakat durum ne olursa olsun Hunyadi, ordusu ile serbestçe gelip Tuna’nın öbür tarafına ordusunu kurmuştur... Surların dışında da şiddetli bir savaş başlamıştır. Türklerin bir hilesinden endişe eden Hunyadi dışarıdaki kuvvetlerine yerlerinden ayrılmamalarını emretmiştir. Fakat bu kuvvetler Türk tarafına doğru bir hücuma geçmiştir. Fatih düşmanı meydana çekerek imha etmek maksadıyla kale dibindeki askerlerin geri çekilmesi emrini verir. Böylece düşman kuvvetleri Türk ordugahına doğru çekilecek ve imha edilecektir. Fakat Hunyadi Fatih’in bu stratejisini anlayarak hemen ordusunun imdadına yetişmiştir... Durum her ne olursa olsun düşman kuvvetleri Türk ordugahına doğru ilerlemeye başlamışlardır. Kritovulos Belgrad müdafilerinin Türk toplarının yanına kadar gelerek ordugahı yağmaladıklarını anlatmaktadır. Ordugahın yağmalanmasının Fatih’in ileri atılıp saldırmasıyla engellediğini nakletmektedir. Vezirler Sultana ordugahı terk etmesini ve emin bir yere çekilmesini telkin ettiler, fakat Fatih Sultan Mehmed “Düşmenden yüz döndürmek sıngun nişanudur...” diyerek düşmanın bu hali karşısında bizzat öne atılarak düşmana hücum etmiştir. Böylece Osmanlılar ordugaha hücum eden öndeki düşman kuvvetlerini geri püskürttüler ve kılıçtan geçirdiler... İleri atılan bu kahraman Osmanlı padişahının bir yanında Özgüroglu İsa Bey, bir yanında da İshak Beyoğlu İsa Bey vardır. Padişah üzerine gelen birkaç kişiyi öldürmeye muvaffak olmuştur. Tam bu sırada alnından ve dizinden yaralanmıştır... Fatih’in düşman ordusunun üzerine atılması ve cesareti büyük bir bozgunu önlemiştir. Yeniden toparlanan ordu tekrar taarruza geçmiştir. Bu arada padişah bin bir güçlükle ikna edilip tehlikeli bölgeden uzaklaştırılmıştır. Türk ordusu da bir hayli yıpranmış ve kayıp vermiştir. Türk ordusunun yıpranması ve Belgrad’ın bu şartlar altında alınamayacağı harp meclisinde münakaşa ve müzakere edilerek muhasaranın kaldırılmasına karar verilmiştir. Böylece Osmanlı ordusu muhasarayı kaldırarak geri dönmüştür. |via=Dergipark}}</ref> At the end of 1455, after receiving reports of the imminent Ottoman attack, Hunyadi began preparations of his own for the fortification of the Danube, informing the [[papal legate]] that he was ready to contribute, at his own expenses, 7,000 men in the fight against the Ottomans and asking for military assistance.{{sfn | Muresanu | Treptow | 2018 | p=211}} Hunyadi then armed the [[Belgrade fortress]] with 5,000 mercenaries that he placed under the command of his brother-in-law [[Michael Szilágyi|Mihály Szilágyi]]{{sfn | Muresanu | Treptow | 2018 | p=214}} and his own eldest son [[Laszlo Hunyadi|László]].<ref name="Tucker 2009 p. 399" /> Belgrade inhabitants came to help transporting the war machines.{{sfn | Muresanu | Treptow | 2018 | p=214}} Hunyadi then proceeded to form a relief army of 12,000.<ref name="Rogers Caferro Reid 2010 p. 2-PA45" /> In April 1456 general mobilisation was decreed following a [[Diet (assembly)|Diet]] between the king and the noblemen.{{sfn | Muresanu | Treptow | 2018 | p=214}}

An Italian [[Franciscan]] friar allied to Hunyadi, [[Giovanni da Capistrano]], sent as an [[inquisitor]] to Hungary to eliminate or convert so-called [[heretics]], (non-Catholics){{sfn|Housley|2012|p=30}} started preaching a [[crusade]] to attract [[peasantry|peasants]] and local countryside [[gentry|landlords]] to join the defence of Europe.{{sfn | Muresanu | Treptow | 2018 | p=213}} 
The crusaders numbering about 25,000 included an inexperienced peasant force of about 18,000 some of them carrying only clubs and slings. The [[Conscription|recruits]] came under Hunyadi's banner, the core of which consisted of smaller bands of seasoned mercenaries and a few groups of minor knights. All in all, Hunyadi managed to build a force of 25–30,000 men.<ref name="Rogers Caferro Reid 2010 p. 2-PA45" />

As the Ottoman army neared Belgrade, it passed through Sofia and proceeded towards the Danube, traversing the [[Morava Valley|valley of Morava]]. On 18 of June, it encountered a Serbian Army of approximately 9,000 soldiers, dispatched to halt the Ottoman progress. The smaller Serbian forces were utterly devastated and defeated by the advancing Ottoman troops; towards the end of the month the Ottomans appeared near Belgrade.{{sfn | Muresanu | Treptow | 2018 | p=218}}

== Siege ==

=== Preparation ===
[[File:Thuróczy krónika - Nándorfehérvár ostroma.jpg|thumb|250x250px|The Siege of Belgrade ([[Chronica Hungarorum]], 1488)]]
Before Hunyadi could assemble his forces, the Ottoman troops from the army of [[Mehmed II]] (160,000 men in early accounts, 60–70,000 according to newer research) started appearing near Belgrade in the last days of June.{{sfn | Muresanu | Treptow | 2018 | p=218}}

Szilágyi could rely on a force of only 5,000–7,000 men in the castle. Mehmed set up his siege on the neck of the headland and started heavily bombarding the city's walls on July 4. He arrayed his men in three sections: The [[Rumelia Eyalet|Rumelian]] corps had the majority of his 300 cannons, while his fleet of 200 river war vessels had the rest of them. The Rumelians were arrayed on the right wing and the [[Anatolia]]n corps were arrayed on the left. In the middle were the personal guards of the [[Sultan]], the [[Janissary|Janissaries]], and his command post. The Anatolian corps and the Janissaries were both heavy infantry troops. Mehmed posted his river vessels mainly to the northwest of the city to patrol the marshes and ensure that the fortress was not reinforced. They also kept an eye on the [[Sava]] river to the southwest to avoid the infantry from being outflanked by Hunyadi's army. The zone from the [[Danube]] eastwards was guarded by the [[Sipahi]], the Sultan's feudal heavy cavalry corps, to avoid being outflanked on the right.[[File:Kalemegdanska tvrđava IMG 1941.JPG|thumb|Part of [[Belgrade Fortress]] from the 17th century]]When Hunyadi was informed of this, he was in the south of Hungary recruiting additional light cavalry troops for the army, with which he would intend to lift the siege. Although relatively few, his fellow nobles were willing to provide manpower, and the peasants were more than willing to do so. Capistrano, the Friar sent to Hungary by the Vatican both to find heretics and to preach a [[crusade]] against the [[Ottoman Empire|Ottomans]], managed to raise a large, albeit poorly trained and equipped, peasant army, with which he advanced towards Belgrade. Capistrano and Hunyadi travelled together though commanding the army separately. Both of them had gathered around 40,000–50,000 troops altogether. Once reports of the assembled relief army approaching reached the Ottoman camp, Mehmed held a war council with his generals to determine his army's next actions.<ref name=":0" /> [[Karaca Pasha]] recommended that a part of Ottoman army should cross the Danube to counter the approaching relief force.<ref name=":1">{{Cite book |last=Tansel |first=Selahattin |title=Osmanlı Kaynaklarına Göre Fatih Sultan Mehmed'in Siyasi ve Askeri Faaliyeti |publisher=Türk Tarih Kurumu |year=1953 |isbn=9789751610812 |pages=122–123 |language=tr |trans-title=Mehmed the Conqueror's Political and Military Activity per Ottoman Sources |quote=Tuna'nın öte yakasında Macar ordusunun toplanmaya başlandığı duyuldu.

Bu mecliste Karaca Bey çok enteresan bir fikir ortaya attı.

The outnumbered defenders relied mainly on the strength of the formidable castle of Belgrade, which was at the time one of the best engineered in the Balkans. Belgrade had been designated as the capital of the [[Serbian Despotate]] by [[Stefan Lazarević]] 53 years prior, in 1403–1404, and remained in Serbian hands until 1427, when it was returned to Hungarian king [[King Sigismund of Hungary|Sigismund]].{{sfn|Ćirković|2004|p=89, 102}} The fortress was located on a hill and designed in an elaborate form with three lines of defence: the inner castle with the palace, a huge upper town with the main military camps, four gates and a double wall, as well as the lower town with the cathedral in the urban centre and a port at the Danube. This building endeavour was one of the most elaborate military architecture achievements of the Middle Ages as it also benefitted from the natural obstacle of the rivers being at the junction of the Danube and the Sava.{{sfn | Muresanu | Treptow | 2018 | p=218}} On 2 July Capistrano arrived at Belgrade.{{sfn | Muresanu | Treptow | 2018 | p=219}}

=== Naval battle ===
[[File:fortress Belgrade.jpg|thumb|Fortress of Belgrade as it looked in the Middle Ages. The lower and upper town with the palace are visible.]]Hunyadi established his camp in the vicinity of the Zemun fortress, while the Ottoman fleet encircled Belgrade along the Danube to put a stop to the provisioning of the city.{{sfn | Muresanu | Treptow | 2018 | p=218}} Hunyadi's primary objective was to secure the river passage to support and supply the besieged garrison. To achieve this, he commanded the assembly of all ships on the Danube and communicated with Szilágyi, instructing him to be prepared to launch an attack on the Ottoman fleet from a strategic position. Szilágyi readied around forty vessels, crewed by Serbians from the city.{{sfn | Muresanu | Treptow | 2018 | p=218}} The Ottoman Naval [[Flotilla]] facing them, depending on the source, was made up of 21 to as much as 200 vessels.<ref name="papacy">{{Cite book |last=Setton |first=Kenneth Meyer |url=https://books.google.com/books?id=0Sz2VYI0l1IC |title=The Papacy and the Levant, 1204-1571 |publisher=American Philosophical Society |year=1978 |isbn=0-87169-127-2 |pages=173–175 |language=en |quote=Western contemporaries and some modern historians have reported, with much exaggeration, that more than 150,000 men had been mustered in the plains between Istanbul and Adrianople, and that the sultan had prepared a fleet of some two hundred river boats to be sent up the Danube and assembled at Vidin. A German source of late August, 1456, says, however, that Mehmed had no more than twenty-one ships! The ships were easier to count than the men. If Mehmed maintained as many as thirty thousand men at the siege of Belgrade, he did well.}}</ref>

On July 14, 1456, after 5 hours of battle on the river, Hunyadi broke the naval blockade sinking three large Ottoman galleys and capturing four large vessels and 20 smaller ones. By destroying the Sultan's fleet, Hunyadi was able to transport his troops and much-needed food into the city. The fort's defenders were also reinforced.

=== Ottoman assault ===

Infuriated by the failure on the Danube, Mehmed ordered his cannoneers to continuously fire upon the city walls, in preparation for a final offensive to take the city.<ref name=":5">{{Cite book |last=Babinger |first=Franz |title=Fatih Sultan Mehmed ve Zamanı |publisher=Oğlak Yayıncılık |isbn=975-329-417-4 |publication-date=2003 |pages=132–137 |language=tr |trans-title=Mehmed the Conqueror and His Times}}</ref> The defenders responded with fire of their own, managing to kill Karaca Pasha with a cannonball.<ref name=":2">{{Cite book |last=Mureșanu |first=Camil |title=John Hunyadi: Defender of Christendom |publisher=Histria Books |year=2021 |isbn=978-1-59211-115-2 |pages=221–224 |language=en |quote=The Ottoman cannons fired incessantly at the fortress... The defenders shot a flight of arrows at the Ottoman soldiers who were busy preparing for the general assault. They were constantly firing their cannons as well. Each day, the Ottomans launched small attacks, which were forcefully rejected. A cannonball killed Tadji Karadja, the beylerbey of Rumelia, who was in direct command of the siege. This incident demoralized the soldiers in the Rumelian army... Mehmed II decided to call for a general assault on July 21... The reinforcements that kept coming across the Sava allowed, toward evening, the launching of a counterattack that repelled the Ottomans completely. The city was reconquered, the janissaries ran back to the cannons where they had started a few hours earlier. The battle continued after dark, but Hunyadi gave orders to halt the pursuit, thus giving the troops time to rest. At the break of dawn on July 22 things remained quiet. But gradually battle began again. Animated by the victory of the previous day and evening, the Christian troops could not be restrained. Without waiting for any orders, the people’s detachments began to harass the Ottomans, engaging in isolated confrontations with units of Ottoman cavalry. The battle quickly gained proportion. The entire camp of crusaders crossed the Sava and rushed upon the armies from Anatolia. At that time, John Hunyadi was near the ships. Seeing that the army could not be stopped from the struggle it had begun, he decided to intervene with his troops, scattered inside the fortress and throughout the city. A general attack broke out against the Ottoman camp. The cannons of the sultan were captured and turned against the Ottomans who fled. The janissaries, however, were still fighting vigorously. Mehmed II, although wounded by an arrow in his calf, stayed among them... Mehmed repelled the troops that had penetrated into his camp and ordered that the cannons be recovered at any price. The Ottomans attacked three times, but the deadly fire they confronted vanquished them... The sultan and the troops around him resisted in their camp until evening. During the night of July 22 to 23, the Ottomans buried their dead according to their custom, loaded their wounded in a long row of wagons, and evacuated the camp in a hurry, heading southeast. The victorious army entered the Ottoman camp. They found immense loot there, left behind by the retreating Ottoman army.}}</ref> In the build-up to the general assault, the Ottomans launched small attacks each day, which were forcefully rejected.<ref name=":2" /> The continuous bombardment resulted in several breaches opening on the walls of the fortress. On July 21 Mehmed launched an all-out assault that began at sundown and continued all night. The besieging army flooded the city and then started its assault on the fort. As this was the most crucial moment of the siege, Hunyadi ordered the defenders to throw tarred wood and other flammable material, and then set it afire. Soon a wall of flames separated the Janissaries fighting in the city from their fellow soldiers trying to breach through the gaps into the upper town. The battle between the encircled Janissaries and Szilágyi's soldiers inside the upper town was turning in favour of the Christians, and the Hungarians managed to beat off the fierce assault from outside the walls. The Janissaries remaining inside the city were thus massacred while the Ottoman troops trying to breach the upper town suffered heavy losses.

=== Final battle ===
[[File:Siege of Belgrade (Nándorfehérvár) 1456.jpg|thumb|Siege of Belgrade (in Hungarian: Nándorfehérvár) 1456. Hünername 1584]]

The next day, by some accounts, the peasant crusaders started a spontaneous action, and forced Capistrano and Hunyadi to make use of the situation. Despite Hunyadi's orders to the defenders not to try to loot the Ottoman positions, some of the units crept out from demolished ramparts, took up positions across from the Ottoman line, and began harassing enemy soldiers. Ottoman [[Sipahi]]s tried without success to disperse the harassing force. At once, more defenders joined those outside the wall. What began as an isolated incident quickly escalated into a full-scale battle.

John of Capistrano at first tried to order his men back inside the walls, but soon found himself surrounded by about 2,000 peasant levymen. He then began leading them toward the Ottoman lines, crying, "The Lord who made the beginning will take care of the finish!" Capistrano led his crusaders to the Ottoman rear across the [[Sava]] river. At the same time, Hunyadi started a desperate charge out of the fort to capture the cannons in the Ottoman encampment.

The Christian counter offensive managed to gain significant ground against the Ottoman troops, eventually reaching as far as the Ottoman camp<ref name=":3">{{Cite book |last=Uzunçarşılı |first=İsmail Hakkı |title=Osmanlı Tarihi Cilt II |publisher=Türk Tarih Kurumu |year=2019 |isbn=9789751600127 |pages=15–18 |language=tr |trans-title=History of the Ottomans Volume II |quote=Kara tarafındaki hendeği doldurmuş olan Türk muhasara kuvvetleri şiddetli bir hücum neticesinde Belgrad'a girdikleri sırada diğer taraftan da şehrin yardımına yetişen Jan Hunyadi içeri girmiş ve iki taraf arasında şiddetli bir mücadele olmuştu.

In part their advance may have been possible because Hunyadi had deliberately withdrawn to the citadel that Stefan Lazarević had refurbished decades before. From there the garrison’s defenders launched a counterattack that drove the Ottomans from the Upper Town. The fighting among the ruined walls was fierce - as Hunyadi later recalled, in an oft-repeated line, it unfolded “not in a fortress, but in a field” - and seems to have lasted well into the next day. Mehmed and his generals soon realized that the city would not fall so easily, and they changed tactics. The sultan ordered a feigned retreat, hoping to draw the defenders out for a battle in the open field. It was a tactic Hunyadi knew well, and he ordered his troops to hold back. Capistrano’s followers, though, seem not to have known, or not to have cared. They advanced across the Sava, by some accounts under Capistrano’s direction, and began pillaging the abandoned Ottoman positions. A full counterattack soon erupted. Whether by accident or by design, the end result was the same: Belgrade’s defenders captured the Ottoman artillery positions and drove the sultan’s troops all the way back to his own tents. There, again, Mehmed himself is said by at least some accounts to have been wounded, and to have killed many with his own hands.

== Aftermath ==
It is claimed that after the defeat, while he and his army were retreating into [[Ottoman Bulgaria|Bulgaria]], the failure as well as the ensuing loss of no less than 24,000 of his best soldiers angered Mehmed in such a manner that, in an uncontrollable fit of fury, he wounded a number of his generals with his own sword, before ordering their executions.<ref>{{cite book |author=Radu R Florescu |url=https://archive.org/details/draculaprinceofm00flor/page/80 |title=Dracula, Prince of Many Faces: His Life and His Times |author2=Raymond T.

However, the Hungarians paid dearly for this victory. Plague broke out in the camp, from which [[John Hunyadi]] himself died three weeks later in Zimony, Hungary (later Zemun, Serbia) on 11 August 1456.<ref name="Tucker 2009 p. 399" /> He was buried in the Cathedral of ''Gyulafehérvár'' (now [[Alba Iulia]]), the capital of [[Transylvania]].

As the design of the fortress had proved its merits during the siege, some additional reinforcements were made by the Hungarians. The weaker eastern walls, where the Ottomans broke through into the upper town were reinforced by the [[Zindan Gate]] and the heavy [[Nebojša Tower]]. This was the last of the great modifications to the fortress until 1521, when Mehmed's great-grandson [[Suleiman the Magnificent|Suleiman]] [[Siege of Belgrade (1521)|eventually captured it]].

As he had previously ordered all [[Catholic Church in Europe|Catholic kingdoms]] to pray for the victory of the defenders of Belgrade, the Pope celebrated the victory by making an enactment to commemorate the day. This led to the legend that the noon bell ritual undertaken in [[Roman Catholicism|Catholic]] and old [[Protestant]] churches, enacted by the [[Pope]] before the battle, was founded to commemorate the victory.<ref>{{Cite web |last= |first= |date=November 9, 2015 |title=Hunyadi and the noon bell ritual |url=https://dailynewshungary.com/hunyadi-and-the-noon-bell-ritual/ |website=Daily News Hungary}}</ref> The day of the victory, July 22, has been a [[Public holidays in Hungary|memorial day in Hungary]] ever since.<ref>[http://www.politics.hu/20110705/anniversary-of-1456-victory-over-ottomans-becomes-memorial-day/ Anniversary of 1456 victory over Ottomans becomes memorial day] politics.hu</ref>

This custom still exists also among Protestant and Orthodox congregations. In the history of the [[University of Oxford]], the victory was welcomed with the ringing of bells and great celebrations in England. Hunyadi sent a special courier, Erasmus Fullar, among others to Oxford with the news of the victory.<ref>Imre Lukinich: ''A History of Hungary in Biographical Sketches'' (p. 109.) {{ISBN?}}</ref>

The victory stopped the Ottoman advance towards Europe beyond the Balkans for 70 years, though they made other incursions such as the taking of [[Otranto]] between 1480 and 1481; and the raid of [[Croatia in the union with Hungary|Croatia]] and [[Styria (duchy)|Styria]] in 1493. Belgrade would continue to protect Hungary from Ottoman attacks until the fort [[Siege of Belgrade (1521)|fell to the Ottomans in 1521]].

After the siege of Belgrade stopped the advance of Mehmed II towards Central Europe, Serbia and Bosnia were absorbed into the Empire. [[Principality of Wallachia|Wallachia]], the [[Crimean Khanate]], and eventually [[Principality of Moldavia|Moldavia]] were merely converted into vassal states due to the strong military resistance to Mehmed's attempts of conquest. There were several reasons of why the Sultan did not directly attack Hungary and why he gave up the idea of advancing in that direction after his unsuccessful siege of Belgrade. The mishap at Belgrade indicated that the Empire could not expand further until Serbia and Bosnia were transformed into a secure base of operations. Furthermore, the significant political and military power of [[Kingdom of Hungary (1301–1526)|Hungary]] under [[Matthias Corvinus]] in the [[Balkans|region]] surely influenced this hesitation too. Moreover, Mehmed was also distracted in his attempts to suppress insubordination from his [[Principality of Moldova|Moldovan]] and [[Principality of Wallachia|Wallachian]] vassals.

With Hunyadi's victory at Belgrade, both [[Vlad III the Impaler]] and [[Stephen III of Moldavia]] came to power in their own domains, and Hunyadi himself went to great lengths to have his son [[Matthias Corvinus|Matthias]] placed on the [[Kingdom of Hungary (1301–1526)|Hungarian throne]]. While fierce resistance and Hunyadi's effective leadership ensured that the daring and ambitious Sultan Mehmed would only get as far into Europe as the Balkans, the Sultan had already managed to transform the Ottoman Empire into what would become one of the most feared powers in Europe (as well as in Asia) for centuries. Most of Hungary was eventually conquered in 1526 at the [[Battle of Mohács]]. Ottoman [[Sunni Islam|Muslim]] [[Ottoman wars in Europe|expansion into Europe]] continued with menacing success until the [[Siege of Vienna (1529)|siege of Vienna]] in 1529, although Ottoman power in Europe remained strong and still threatening to Central Europe at times until the [[Battle of Vienna]] in 1683.
