Sigismund, Holy Roman Emperor

Born in Nuremberg, Sigismund was the son of the Holy Roman Emperor, Charles IV, and of his fourth wife, Elizabeth of Pomerania, who was the granddaughter of King Casimir III of Poland and the great-granddaughter of the Grand Duke of Lithuania, Gediminas. He was named after Saint Sigismund of Burgundy, the favourite saint of Sigismund's father. From Sigismund's childhood he was nicknamed the "ginger fox" (liška ryšavá) in the Crown of Bohemia, on account of his hair colour.

Sigismund's first wife, Mary I, Queen of Hungary.

King Louis the Great of Hungary and Poland always had a good and close relationship with Emperor Charles IV, and Sigismund was betrothed to Louis' eldest daughter, Mary, in 1374, when he was six years old. Upon his father's death in 1378, young Sigismund became Margrave of Brandenburg and was sent to the Hungarian court, where he soon learnt the Hungarian language and way of life, and became entirely devoted to his adopted country.[2] King Louis named him as his heir and appointed him his successor as King of Hungary.

In 1381, the then 13-year-old Sigismund was sent to Kraków by his eldest half-brother and guardian Wenceslaus, King of Germany and Bohemia, to learn Polish and to become acquainted with the land and its people. King Wenceslaus also gave him Neumark to facilitate communication between Brandenburg and Poland.

The disagreement between Polish landlords of Lesser Poland on one side and landlords of Greater Poland on the other, regarding the choice of the future King of Poland, finally ended in choosing the Lithuanian side. The support of the lords of Greater Poland was however not enough to give Prince Sigismund the Polish crown. Instead, the landlords of Lesser Poland gave it to Mary's younger sister Jadwiga I of Poland, who married Jogaila of Lithuania.

On the death of her father in 1382, his betrothed, Mary, became queen of Hungary and Sigismund married her in 1385 in Zólyom (today Zvolen). The next year, he was accepted as Mary's future co-ruler by the Treaty of Győr. However, Mary was captured, together with her mother, Elizabeth of Bosnia, who had acted as regent, in 1387 by the rebellious House of Horvat, Bishop Paul Horvat of Mačva, his brother John Horvat and younger brother Ladislav. Sigismund's mother-in-law was strangled, while Mary was liberated.

Having secured the support of the nobility, Sigismund was crowned King of Hungary at Székesfehérvár on 31 March 1387.[3] Having raised money by pledging Brandenburg to his cousin Jobst, margrave of Moravia (1388), he was engaged for the next nine years in a ceaseless struggle for the possession of this unstable throne.[2] The central power was finally weakened to such an extent that only Sigismund's alliance with the powerful Czillei-Garai League could ensure his position on the throne.[4] It was not for entirely selfless reasons that one of the leagues of barons helped him to power: Sigismund had to pay for the support of the lords by transferring a sizeable part of the royal properties. (For some years, the baron's council governed the country in the name of the Holy Crown). The restoration of the authority of the central administration took decades of work. The bulk of the nation headed by the House of Garai was with him; but in the southern provinces between the Sava and the Drava, the Horvathys with the support of King Tvrtko I of Bosnia, Mary's maternal uncle, proclaimed as their king Ladislaus, king of Naples, son of the murdered Charles II of Hungary. Not until 1395 did Nicholas II Garai succeed in suppressing them.[2] Mary died heavily pregnant in 1395.

To ease the pressure from Hungarian nobles, Sigismund tried to employ foreign advisors, which was not popular, and he had to promise not to give land and nominations to anyone other than Hungarian nobles. However, this was not applied to Stibor of Stiboricz, who was Sigismund's closest friend and advisor. On a number of occasions, Sigismund was imprisoned by nobles, but with help of the armies of Garai and Stibor of Stiboricz, he would regain power.

In 1396, Sigismund led the combined armies of Christendom against the Turks, who had taken advantage of the temporary helplessness of Hungary to extend their dominion to the banks of the Danube. This crusade, preached by Pope Boniface IX, was very popular in Hungary. The nobles flocked in their thousands to the royal standard, and were reinforced by volunteers from nearly every part of Europe. The most important contingent being that of the French led by John the Fearless, son of Philip II, Duke of Burgundy. Sigismund set out with 90,000 men and a flotilla of 70 galleys. After capturing Vidin, he camped with his Hungarian armies before the fortress of Nicopolis. Sultan Bayezid I raised the siege of Constantinople and, at the head of 140,000 men, completely defeated the Christian forces in the Battle of Nicopolis fought between the 25 and 28 September 1396.[2] Sigismund returned by sea and through the realm of Zeta, where he ordained a local Montenegrin lord Đurađ II with the islands of Hvar and Korčula for resistance against the Turks; the islands were returned to Sigismund after Đurađ's death in April 1403.

The disaster at Nicopolis angered several Hungarian lords, leading to instability in the kingdom. Deprived of his authority in Hungary, Sigismund then turned his attention to securing the succession in Germany and Bohemia, and was recognized by his childless half-brother Wenceslaus IV as Vicar-General of the whole Empire. However, he was unable to support Wenceslaus when he was deposed in 1400, and Rupert of Germany, Elector Palatine, was elected German king in his stead.[2]

On his return to Hungary in 1401, Sigismund was imprisoned once and deposed twice. In 1401, Sigismund helped an uprising against Wenceslaus IV, during the course of which the Bohemian king was taken prisoner, and Sigismund ruled Bohemia for nineteen months. He released Wenceslaus in 1403. In the meantime, a group of Hungarian noblemen swore loyalty to the last Anjou monarch, Ladislaus of Naples, putting their hands on the relic of Saint Ladislas of Hungary in Nagyvárad (today Oradea). Ladislaus was the son of the murdered Charles II of Hungary, and thus a distant relative of the long dead King Louis I of Hungary. Ladislaus captured Zara (today Zadar) in 1403, but soon stopped any military advance. This struggle in turn led to a war with the Republic of Venice, as Ladislaus had sold the Dalmatian cities to the Venetians for 100,000 ducats[2] before leaving for his own land. In the following years Sigismund acted indirectly to thwart Ladislaus' attempts to conquer central Italy, by allying with the Italian cities resisting him and by applying diplomatic pressure on him.

Due to his frequent absences attending to business in the other countries over which he ruled, he was obliged to consult Diets in Hungary with more frequency than his predecessors and institute the office of Palatine as chief administrator while he was away.[5] In 1404, Sigismund introduced the Placetum Regium. According to this decree, Papal bulls could not be pronounced in Hungary without the consent of the king.

During his long reign, the royal castle of Buda became probably the largest Gothic palace of the late Middle Ages.

In about 1406, Sigismund married Mary's cousin Barbara of Celje, daughter of Count Hermann II of Celje. Hermann's mother Catherine (of the House of Kotromanic) and Mary's mother Queen Elisabeth of Bosnia were sisters, or cousins who were adoptive sisters.

Sigismund managed to establish control in Slavonia. He did not hesitate to use violent methods (see Bloody Sabor of Križevci), but from the river Sava to the south his control was weak. Sigismund personally led an army of almost 50,000 "crusaders" against the Bosnians, culminating with the Battle of Dobor in 1408, a massacre of about 200 noble families.

Threatened by Ottoman expansion, king Sigismund managed to strengthen the security of southern Hungarian borders by entering into a defensive alliance with despot Stefan Lazarević of Serbia. In 1403, Hungarian possessions in northwestern regions of Serbia (city of Belgrade and the Banate of Macsó), were given to despot Stefan, who pledged his allegiance to king Sigismund, remaining kings loyal vassal until death in 1427. Stefan's successor George Branković of Serbia also pledged his allegiance to Sigismund, returning Belgrade to the king. By maintaining close relations with Serbian rulers, Sigismund succeeded in securing southern borders of his realm.[6][7]

Sigismund founded his personal order of knights, the Order of the Dragon, after the victory at Dobor. The main goal of the order was fighting the Ottoman Empire. Members of the order were mostly his political allies and supporters. The main members of the order were Sigismund's close allies Nicholas II Garay, Hermann II of Celje, Stibor of Stiboricz, and Pippo Spano. The most important European monarchs became members of the order. He encouraged international trade by abolishing internal duties, regulating tariffs on foreign goods and standardizing weights and measures throughout the country.

After the death of King Rupert of Germany in 1410, Sigismund – ignoring the claims of his half-brother Wenceslaus – was elected as successor by three of the electors on 10 September 1410, but he was opposed by his cousin Jobst of Moravia, who had been elected by four electors in a different election on 1 October. Jobst's death 18 January 1411 removed this conflict and Sigismund was again elected king on 21 July 1411. His coronation was deferred until 8 November 1414, when it took place at Aachen.[2]

On a number of occasions, and in 1410 in particular, Sigismund allied himself with the Teutonic Knights against Władysław II of Poland. In return for 300.000 ducats he would attack Poland from the south after the truce on St. John's Day, 24 June expired. Sigismund ordered his most loyal friend Stibor of Stiboricz to set up the attack on Poland. Stibor of Stiboricz was of Polish origin and from the main line of the powerful Clan of Ostoja that had also been against choosing Jagiello as King of Poland. With the support of Sigismund, Stibor become one of the most influential men in late medieval Europe, holding titles as Duke of Transylvania and owning about 25% of modern-day Slovakia, including 31 castles of which 15 were situated around the 406 km long Váh river with surrounding land that was given to him by Sigismund. In the diplomatic struggle to prevent war between Poland-Lithuania, which was supported by the Muscovites, and the Teutonic Knights, Sigismund used Stibor's fine diplomacy to gain financially. The Polish side appointed several negotiators and most of them were also from the Clan of Ostoja, distant relations of the Stibors. However, those "family meetings" could not prevent the war and an alliance of twenty-two western states formed an army against Poland in the Battle of Grunwald in July 1410. Stibor attacked then Nowy Sącz and burned it to the ground, but after that he returned with his army back to the Beckov Castle. After the Polish-Lithuanian victory in the Battle of Grunwald, the Teutonic knights had to pay a huge sum of silver to Poland as reparation and again, through diplomacy of his friend Stibor, Sigismund was able to borrow all this silver from King Władysław II of Poland on good conditions. In the light of facts about the diplomatic work of Stibor and the Clan of Ostoja that was following the politics of King Sigismund, one can question whether Sigismund actually joined the anti-Polish alliance.[8]

From 1412 to 1423, Sigismund campaigned against the Venetians in Italy. The king took advantage of the difficulties of Antipope John XXIII to obtain a promise that a council should be called in Constance in 1414 to settle the Western Schism. He took a leading part in the deliberations of this assembly, and during the sittings made a journey to France, England and Burgundy in a vain attempt to secure the abdication of the three rival popes. The council ended in 1418, solving the Schism and — of great consequence to Sigismund's future career — having the Czech religious reformer, Jan Hus, burned at the stake for heresy in July 1415. The complicity of Sigismund in the death of Hus is a matter of controversy. He had granted him a safe-conduct and protested against his imprisonment;[2] and Hus was burned during Sigismund's absence.

When at one point during the council a cardinal corrected Sigismund's Latin, Sigismund replied Ego sum rex Romanus et super grammaticam ("I am king of the Romans and above grammar").[9] Thomas Carlyle nicknamed Sigismund "Super Grammaticam".[10][11]

An alliance with England against France, and a failed attempt, owing to the hostility of the princes, to secure peace in Germany by a league of the towns,[2] were his main acts during these years. Also, Sigismund granted control of the Margraviate of Brandenburg (which he had received back after Jobst's death) to Frederick I of Hohenzollern, burgrave of Nuremberg (1415). This step made the Hohenzollern family one of the most important in Germany.

Sigismund began to shift his alliance from France to England after the French defeat at the Battle of Agincourt. The signing of the Treaty of Canterbury on 15 August 1416 culminated diplomatic efforts between Henry V of England and Sigismund and resulted in a defensive and offensive alliance against France. This, in turn, led the way to the resolution of the papal schism.[12] The close relationship that developed between Henry V and the Emperor resulted in Sigismund being inducted into the Order of the Garter.[13]

In 1419, the death of Wenceslaus IV left Sigismund titular King of Bohemia, but he had to wait for seventeen years before the Czech Estates would acknowledge him. Although the two dignities of King of the Romans and King of Bohemia added considerably to his importance, and indeed made him the nominal temporal head of Christendom, they conferred no increase of power and financially embarrassed him. It was only as King of Hungary that he had succeeded in establishing his authority and in doing anything for the order and good government of the land. Entrusting the government of Bohemia to Sofia of Bavaria, the widow of Wenceslaus, he hastened into Hungary.[2]

The Bohemians, who distrusted him as the betrayer of Hus, were soon in arms; and the flame was fanned when Sigismund declared his intention of prosecuting the war against heretics. Three campaigns against the Hussites ended in disaster although the army of his most loyal ally Stibor of Stiboricz and later his son Stibor of Beckov could hold the Hussite side away from the borders of the Kingdom. The Turks were again attacking Hungary. The king, unable to obtain support from the German princes, was powerless in Bohemia. His attempts at the diet of Nuremberg in 1422 to raise a mercenary army were foiled by the resistance of the towns; and in 1424 the electors, among whom was Sigismund's former ally, Frederick I of Hohenzollern, sought to strengthen their own authority at the expense of the king. Although the scheme failed, the danger to Germany from the Hussites led to the Union of Bingen, which virtually deprived Sigismund of the leadership of the war and the headship of Germany.[2]

In 1428, Sigismund led another campaign against the Turks, but again with few results. In 1431, he went to Milan where on 25 November he received the Iron Crown as King of Italy; after which he remained for some time at Siena, negotiating for his coronation as emperor and for the recognition of the Council of Basel by Pope Eugenius IV. He was crowned emperor in Rome on 31 May 1433, and after obtaining his demands from the Pope returned to Bohemia, where he was recognized as king in 1436, though his power was little more than nominal.[2] Shortly after he was crowned, Pope Eugenius began attempts to create a new anti-Ottoman alliance.[14] This was sparked by an Albanian revolt against the Ottomans, which had begun in 1432. In 1435, Sigismund sent Fruzhin, a Bulgarian nobleman, to negotiate an alliance with the Albanians. He also sent Daud, a pretender to the Ottoman throne, in early 1436.[15] However, following the defeat of the rebels in 1436, plans for an anti-Ottoman alliance ended.[15]

Sigismund died on 9 December 1437 at Znojmo (German: Znaim), Moravia (now Czech Republic), and as ordered in life, he was buried at Nagyvárad, Hungary (today Oradea, Romania), next to the tomb of the king Saint Ladislaus I of Hungary, who was the ideal of the perfect monarch, warrior and Christian for that time and was deeply venerated by Sigismund.[16] By his second wife, Barbara of Celje, he left an only daughter, Elisabeth of Luxembourg, who was married to Albert V, duke of Austria (later German king as Albert II) whom Sigismund named as his successor. As he left no sons, his line of the House of Luxembourg became extinct on his death.[2]

Sigismund was known to speak fluent Hungarian, wore Hungarian-style royal clothes, and even grew his beard in the Hungarian fashion.[17] He also spent huge amounts of money during his reign to rebuild the Gothic castles of Buda and Visegrád in the Kingdom of Hungary, ordering the transportation of materials from Austria and Bohemia.[18]

His many affairs with women led to the birth of several legends, as the one that existed decades later during the reign of the King Matthias Corvinus of Hungary. According to this, John Hunyadi was Sigismund's illegitimate son. Sigismund gave a ring to the boy's mother when he was born, but one day in the forest a raven stole it from her, and the ring was only recovered after the bird was hunted down. It is said that this incident inspired the coat of arms of the Hunyadis, and later also appeared in the coat of arms of Matthias "Corvinus".[19]

Sigismund adopted the Hungarian reverence for Saint Ladislaus I of Hungary, who was considered to be an ideal Christian knight at that time. He went on pilgrimage several times to his tomb in Nagyvárad. Before Sigismund died, in Znaim, Moravia, he ordered to be buried next to the king saint.[20]
