Editing Jadwiga of Poland (section)

== Reign ==

=== Coronation (1384) ===
The interregnum that followed Louis's death and caused such internal strife came to an end with Jadwiga's arrival in Poland.{{sfn|Jackson|1999|p=188}}{{sfn|Halecki|1991|p=113}} A large crowd of clerics, noblemen and burghers gathered at Kraków "to greet her with a display of affection",<ref>''The Annals of Jan Długosz'' (A.D. 1384), p. 344.</ref> according to the 15th-century Polish historian, [[Jan Długosz]].{{sfn|Halecki|1991|p=113}} Nobody protested when Archbishop [[Bodzanta]] crowned her on 16 October 1384.{{sfn|Halecki|1991|p=109}}{{sfn|Davies|2005|p=91}} According to traditional scholarly consensus, Jadwiga was crowned king.{{sfn|Frost|2015|p=17 (note 38)}} Thereby, as Robert W. Knoll proposes, the Polish lords prevented her eventual spouse from adopting the same title without their consent.{{sfn|Knoll|2011|p=37}} Stephen C. Rowell, who says that sources that contradict the traditional view outnumber those verifying it, suggests that sporadic contemporaneous references to Jadwiga as king only reflect that she was not a [[queen consort]], but a [[queen regnant]].{{sfn|Frost|2015|p=17 (note 38)}}

Bodzanta, Archbishop of Gniezno, [[Jan Radlica]], [[Bishop of Kraków]], [[Dobrogost of Nowy Dwór]], [[Bishop of Poznań]], and Duke Vladislaus II of Opole were Jadwiga's most trusted advisers during the first years of her reign.{{sfn|Halecki|1991|pp=114–115}} According to a widely accepted scholarly theory, Jadwiga, who was still a minor, was "a mere tool" to her advisers.{{sfn|Gromada|1999|p=434}}{{sfn|Halecki|1991|p=114}} However, Halecki refutes this view, contending that Jadwiga matured quickly and her personality, especially her charm and kindness, only served to strengthen her position.{{sfn|Halecki|1991|p=114}} Already in late 1384 she intervened on Duke Vladislaus's behalf to reconcile him with her mother's favourite, [[Nicholas I Garai]].{{sfn|Halecki|1991|p=116}}

=== Refusal of William (1385) ===
The Polish lords did not want to accept Jadwiga's fourteen-year-old fiancé, William of Habsburg, as their sovereign.{{sfn|Frost|2015|p=17}}{{sfn|Halecki|1991|pp=116–117}} They thought that the inexperienced William and his Austrian kinsmen could not safeguard Poland's interests against its powerful neighbours, especially the [[House of Luxembourg|Luxemburgs]] which controlled [[Kingdom of Bohemia|Bohemia]] and [[Margraviate of Brandenburg|Brandenburg]], and had a strong claim on Hungary.{{sfn|Frost|2015|pp=17, 33}}{{sfn|Halecki|1991|p=117}} According to Halecki, the lords of Lesser Poland were the first to suggest that Jadwiga should marry the pagan duke Jogaila of Lithuania.{{sfn|Halecki|1991|p=118}}

Jogaila sent his envoys{{spaced ndash}}including his brother, [[Skirgaila]], and a German burgher from [[Riga]], Hanul{{spaced ndash}} to Kraków to request Jadwiga's hand in January 1385.{{sfn|Frost|2015|pp=17, 33}}{{sfn|Halecki|1991|pp=121–123}} Jadwiga refused to answer, stating only that her mother would decide.{{sfn|Halecki|1991|p=123}} Jogaila's two envoys left for Hungary and met Queen Elizabeth.{{sfn|Halecki|1991|p=123}}{{sfn|Frost|2015|p=3}} She informed them that "she would allow whatever was advantageous to Poland and insisted that her daughter and the prelates and nobles of the Kingdom had to do what they considered would benefit Christianity and their kingdom",<ref name="Annals_y1385_p345">''The Annals of Jan Długosz'' (A.D. 1385), p. 345.</ref> according to Jan Długosz's chronicle.{{sfn|Halecki|1991|p=127}} The nobles from Kraków, [[Sandomierz]] and Greater Poland assembled in Kraków in June or July and the "majority of the more sensible"<ref name="Annals_y1385_p345"/> voted for the acceptance of Jogaila's marriage proposal.{{sfn|Halecki|1991|p=129}}

[[File:Dymitr z Goraja.jpg|thumb|left|alt=A bearded man on his knees by a young woman who stands at a door holding an axe |''Dymitr of Goraj'' by [[Jan Matejko]] depicts Jadwiga trying to break the castle gate to join William]]
In the meantime, William's father, Leopold III hurried to Buda in late July 1385, demanding the consummation of the marriage between William and Jadwiga before 16 August.{{sfn|Halecki|1991|pp=127, 129}} Queen Elizabeth confirmed the previous agreements about the marriage, ordering Vladislaus II of Opole to make preparations for the ceremony.{{sfn|Frost|2015|p=34}}{{sfn|Halecki|1991|p=130}} According to [[Canon law (Catholic Church)|canon law]], Jadwiga's marriage sacrament could only be completed before her twelfth birthday if the competent prelate testified her precocious maturity.{{sfn|Halecki|1991|p=130}} [[Demetrius of Esztergom|Demetrius]], [[Archbishop of Esztergom]], issued the necessary document.{{sfn|Halecki|1991|p=131}} William went to Kraków in the first half of August, but his entry to Wawel Castle was barred.{{sfn|Halecki|1991|p=132}} Długosz states that Jadwiga and William would only be able to meet in the nearby [[Franciscan]] convent.{{sfn|Halecki|1991|p=132}}

Contemporary or nearly contemporaneous records of the completion of the marriage between William and Jadwiga are contradictory and unclear.{{sfn|Halecki|1991|pp=132–135}}{{sfn|Frost|2015|p=34}} The official accounts of the municipal authorities of Kraków record that on 23 August 1385, an amnesty was granted to the prisoners in the city jail on the occasion of the celebration of the Queen's marriage.{{sfn|Halecki|1991|pp=132–133}} On the other hand, a contemporary Austrian chronicle, the ''Continuatio Claustroneubuzgis'' states that the Poles had tried to murder William before he consummated the marriage.{{sfn|Halecki|1991|p=135}} In the next century, Długosz states that William was "removed in a shameful and offensive manner and driven from the castle" after he entered "the Queen's bedchamber"; but the same chronicler also mentions that Jadwiga was well aware that "many people knew {{nobr|that ...}} she had for a fortnight shared her bed with Duke William and that there had been physical consummation".<ref>''The Annals of Jan Długosz'' (A.D. 1385 and 1386), pp. 346–347.</ref>{{sfn|Halecki|1991|pp=134–135}}

During the night that William entered the queen's bedchamber, a group of Polish noblemen broke into the castle, forcing William to flee, according to Długosz.{{sfn|Halecki|1991|p=135}} After this humiliation, Długosz continued, Jadwiga decided to leave Wawel and join William, but the gate of the castle was locked.{{sfn|Halecki|1991|p=135}} She called for "an axe and [tried] to break it open",<ref>''The Annals of Jan Długosz'' (A.D. 1385), p. 346.</ref> but [[Dymitr of Goraj]] convinced her to return to the castle.{{sfn|Halecki|1991|p=138}}{{sfn|Frost|2015|p=34}} Oscar Halecki says that Długosz's narrative "cannot be dismissed as a romantic legend";{{sfn|Halecki|1991|p=139}} [[Robert I. Frost]] writes that it is a "tale, almost certainly apocryphal".{{sfn|Frost|2015|p=34}} There is no doubt, however, that William of Austria was forced to leave Poland.{{sfn|Davies|2005|p=95}}

=== Marriage to Jogaila (1385–92) ===
Jogaila signed the [[Union of Krewo]] in August 1385, promising Queen Elizabeth's representatives and the Polish lords' envoys that he would convert to Catholicism, together with his pagan kinsmen and subjects, if Jadwiga married him.{{sfn|Frost|2015|pp=47, 50}}{{sfn|Gromada|1999|pp=434–435}} He also pledged to pay 200,000 florins to William of Habsburg in compensation. William never accepted it.{{sfn|Frost|2015|pp=34, 47}} Two days after the Union of Krewo, the [[Teutonic Knights]] invaded Lithuania.{{sfn|Halecki|1991|p=157}}

The ''Aeltere Hochmeisterchronik'' and other chronicles written in the Knights' territory accused the Polish prelates and lords of forcing Jadwiga to accept Jogaila's offer.{{sfn|Halecki|1991|pp=139–140}} According to a Polish legend, Jadwiga agreed to marry Jogaila due to [[divine inspiration]] during her long prayers before a [[crucifix]] in Wawel Cathedral.{{sfn|Halecki|1991|p=139}} Siemowit IV of Mazovia resigned his claim to Poland in December.{{sfn|Frost|2015|p=4}}

The Polish lords' envoys informed Jogaila that they would obey him if he married Jadwiga on 11 January 1386.{{sfn|Frost|2015|p=49}}{{sfn|Halecki|1991|p=147}} Jogaila went to [[Lublin]] where a general assembly unanimously declared him "king and lord of Poland" in early February.{{sfn|Monter|2012|p=74}}{{sfn|Frost|2015|pp=49–50}}{{sfn|Halecki|1991|pp=150–151}} Jogaila went on to Kraków where he was baptized, receiving the Christian name, Władysław, in Wawel Cathedral on 15 February.{{sfn|Davies|2005|p=95}}{{sfn|Halecki|1991|p=152}} Three days later, Władysław-Jogaila, who was between 23- and 35-year old, married 12-year-old Jadwiga.{{sfn|Jackson|1999|p=190}}{{sfn|Halecki|1991|p=152}}{{sfn|Borkowska|2012|p=476}} Władysław-Jogaila styled himself as ''dominus et tutor regni Poloniae'' ("lord and guardian of the Kingdom of Poland") in his first charter issued after the marriage.{{sfn|Halecki|1991|p=155}}

Archbishop Bodzanta crowned Władysław-Jogaila king on 4 March 1386.{{sfn|Frost|2015|p=4}} Poland was transformed into a [[diarchy]]{{spaced ndash}}a kingdom ruled over by two sovereigns.{{sfn|Halecki|1991|p=155}} Jadwiga and her husband did not speak a common language, but they cooperated closely in their marriage.{{sfn|Monter|2012|p=74}} She accompanied him to Greater Poland to appease the local lords who were still hostile to him.{{sfn|Halecki|1991|p=160}} The royal visit caused damage to the peasants who lived in the local prelates' domains, but Jadwiga persuaded her husband to compensate them, saying: "We have, indeed, returned the peasants' cattle, but who can repair their tears?",<ref>''The Annals of Jan Długosz'' (A.D. 1386), p. 348.</ref> according to Długosz's chronicle.{{sfn|Halecki|1991|p=160}} A court record of her order to the judges in favour of a peasant also shows that she protected the poor.{{sfn|Halecki|1991|p=160}}

[[Pope Urban VI]] sent his legate, [[Maffiolus de Lampugnano]], to Kraków to enquire about the marriage of the royal couple.{{sfn|Halecki|1991|p=158}} Lampugnano did not voice any objections, but the Teutonic Knights started a propaganda campaign in favour of William of Habsburg.{{sfn|Halecki|1991|pp=157–159}} Queen Elizabeth pledged to assist Władysław-Jogaila against his enemies on 9 June 1386,{{sfn|Halecki|1991|p=158}} but Hungary had sunken into anarchy.{{sfn|Deletant|1986|p=202}} A group of [[Slavonia]]n lords captured and imprisoned Jadwiga's mother and sister on 25 July.{{sfn|Engel|2001|p=198}} The rebels murdered Queen Elizabeth in January 1387.{{sfn|Engel|2001|pp=198–199}}{{sfn|Halecki|1991|p=164}} A month later, Jadwiga marched at the head of Polish troops to Ruthenia where all but one of the governors submitted to her without opposition.{{sfn|Halecki|1991|pp=165–166}}{{sfn|Gromada|1999|p=435}}
[[File:Simmler Queen Jadwiga's oath.jpg|thumb|alt=A crowned young woman on her knees with her hand on the Bible which is held by an old bearded man |''Queen Jadwiga's Oath'', by [[Józef Simmler]], 1867]]

Duke Vladislaus of Opole also had a claim on Ruthenia but could not convince [[Wenceslaus IV of Bohemia|King Wenceslaus of Germany]] to intervene on his behalf.{{sfn|Halecki|1991|p=166}} Jadwiga confirmed the privileges of the local inhabitants and promised that Ruthenia would never again be separated from the Polish Crown.{{sfn|Halecki|1991|p=166}} After the reinforcements that Władysław-Jogaila sent from Lithuania arrived in August, Halych, the only fortress to resist, also surrendered.{{sfn|Deletant|1986|p=203}} Władysław-Jogaila also came to Ruthenia in September.{{sfn|Deletant|1986|p=203}} Voivode [[Petru II of Moldavia]] visited the royal couple and paid homage to them in [[Lviv]] on 26 September.{{sfn|Deletant|1986|p=203}} Władysław-Jogaila confirmed the privileges that Jadwiga had granted the Ruthenians in October.{{sfn|Halecki|1991|p=166}} She also instructed her subjects to show the same respect for her husband as for herself: in a letter addressed to the burghers of Kraków in late 1387, she stated that her husband was their "natural lord".{{sfn|Monter|2012|p=74}}{{sfn|Halecki|1991|p=156}}

On William's demand, Pope Urban VI initiated a new investigation into the marriage of Jadwiga and Władysław-Jogaila.{{sfn|Halecki|1991|pp=167–168}} They sent Bishop Dobrogost of Poznań to Rome to inform the pope of the [[Christianization of Lithuania]].{{sfn|Halecki|1991|p=170}} In his letter to Bishop Dobrogost, Pope Urban jointly mentioned the royal couple in March 1388, which implied that he had already acknowledged the legality of their marriage.{{sfn|Halecki|1991|p=170}} However, [[Gniewosz of Dalewice]], who had been William of Habsburg's supporter, spread rumours about secret meetings between William and Jadwiga in the royal castle.{{sfn|Halecki|1991|p=170}} Jadwiga took a solemn oath before Jan Tęczyński, stating that she had only had marital relations with Władysław-Jogaila.{{sfn|Halecki|1991|pp=137, 180}} After all witnesses confirmed her oath, Gniewosz of Dalewice confessed that he had lied.{{sfn|Halecki|1991|p=180}} She did not take vengeance on him.{{sfn|Halecki|1991|p=180}}

=== Strife with Sigismund (1392–95) ===

Jadwiga's brother-in-law, Sigismund, who had been crowned King of Hungary,{{sfn|Engel|2001|p=199}} started negotiations with the Teutonic Knights about partitioning Poland in early 1392.{{sfn|Halecki|1991|p=194}} Jadwiga met Mary in [[Stará Ľubovňa]] in May and returned to Kraków only in early July.{{sfn|Halecki|1991|pp=195–197}} She most probably accompanied her husband to Lithuania, according to Oscar Halecki, because she was far from Kraków till the end of August.{{sfn|Halecki|1991|p=198}} On 4 August, Władysław-Jogaila's cousin, [[Vytautas]], who had earlier fled from Lithuania to the Teutonic Knights, paid homage to Władysław-Jogaila near [[Lida]] in Lithuania on 4 August.{{sfn|Halecki|1991|p=198}}

Negotiations between Sigismund and the [[Grand Master of the Teutonic Knights]], [[Konrad von Wallenrode]], continued with the mediation of Vladislaus of Opole.{{sfn|Halecki|1991|pp=200–201}} However, Hungary's southern border was exposed to Ottoman incursions, preventing Sigismund from taking military measures against Poland.{{sfn|Halecki|1991|p=207}} Wallenrode died on 25 July 1393.{{sfn|Halecki|1991|p=211}} His successor, [[Konrad von Jungingen]], opened negotiations with the Poles.{{sfn|Halecki|1991|p=211}} During the discussions, [[Pope Boniface IX]]'s legate, John of Messina, supported the Poles.{{sfn|Halecki|1991|p=211}}
[[File:Stefan wojewoda moldawski slubuje wiernosc.png|thumb|Stephen I of Moldavia's promise of loyalty to Jadwiga and Jogaila against Sigismund]]
Jadwiga was a skilful mediator, famed for her impartiality and intelligence.{{sfn|Gromada|1999|p=435}} She went to Lithuania to reconcile her brother-in-law, Skirgaila, with Vytautas in October 1393.{{sfn|Halecki|1991|p=199}} Relations between Poland and Hungary remained tense.{{sfn|Halecki|1991|p=214}} Sigismund invaded Moldavia, forcing [[Stephen I of Moldavia]] to accept his [[suzerainty]] in 1394.{{sfn|Halecki|1991|p=214}} Soon after the Hungarian troops left Moldavia, Stephen sent his envoys to Jadwiga and Jogaila, promising to assist Poland against Hungary, the [[Ottoman Empire]] and the Teutonic Knights.{{sfn|Halecki|1991|p=214}}

On 17 May 1395, Mary died after a riding accident.{{sfn|Engel|2001|p=201}} According to the 1383 agreement between their mother and the Polish lords, Jadwiga was her childless sister's heir in Hungary.{{sfn|Halecki|1991|p=220}} [[Vlad I of Wallachia]], a Hungarian vassal, issued an act of submission on 28 May, acknowledging Jadwiga and her husband as Mary's legitimate successors.{{sfn|Halecki|1991|p=221}} The widowed king's close supporter, [[Stibor of Stiboricz]], expelled Vlad from Wallachia.{{sfn|Halecki|1991|p=222}} Władysław-Jogaila gathered his troops on the Polish-Hungarian border, but {{ill|Eustache Jolsvai|hu|Jolsvai Leusták}}, [[Palatine of Hungary]], and {{ill|John Kanizsai|hu|Kanizsai János}}, [[Archbishop of Esztergom]], stopped his invasion of Hungary.{{sfn|Engel|2001|p=201}}{{sfn|Halecki|1991|p=222}} In September, Konrad von Jungingen told the [[prince-electors]] of the [[Holy Roman Empire]] that the union of Poland, Lithuania, and Hungary under Władysław-Jogaila's rule would endanger Christendom.{{sfn|Halecki|1991|p=224}} However, most of Sigismund's opponents, who were especially numerous in Croatia, supported the claim of [[Ladislaus of Naples]], the last male member of the Capetian House of Anjou.{{sfn|Halecki|1991|pp=223–224}} On 8 September, the most influential Hungarian lords declared that they would not support any change in government while Sigismund was far from Hungary fighting against the Ottoman Turks.{{sfn|Halecki|1991|p=224}} Before the end of the year, peace negotiations between the representatives of Hungary and Poland ended with an agreement.{{sfn|Halecki|1991|p=225}} Jadwiga adopted the title "heir to Hungary", but she and her husband took no further action against Sigismund.{{sfn|Halecki|1991|pp=226–227}}

=== Conflict with the Teutonic Knights (1395–99) ===

The relationship between Lithuania and the Teutonic Knights remained tense.{{sfn|Halecki|1991|pp=230–233}} Jadwiga and her Polish advisers invited the Grand Master, Konrad von Jungingen, to Poland to open new negotiations in June 1396.{{sfn|Halecki|1991|p=233}} Conflicts with Vladislaus of Opole and Siemowit of Masovia, who had not given up their claims to parts of Ruthenia and [[Cuyavia]], also intensified.{{sfn|Halecki|1991|pp=234–235}} To demonstrate that the territories were under Jadwiga's direct control, Władysław-Jogaila granted the [[Duchy of Belz]] (in Ruthenia) and [[Cuyavia]] to her in early 1397.{{sfn|Halecki|1991|p=235}} However, Jadwiga and her Polish advisers wanted to avoid a war with the Teutonic Order.{{sfn|Frost|2015|p=89}} In response, Władysław-Jogaila replaced most Polish "starostas" (aldermen) in Ruthenia with local Orthodox noblemen.{{sfn|Frost|2015|p=89}} According to German sources, Władysław-Jogaila and Vytautas jointly asked [[Pope Boniface IX]] to sanction Vytautas' coronation as king of Lithuania and Ruthenia.{{sfn|Frost|2015|p=89}}

Jadwiga and Jungingen met in [[Włocławek]] in the middle of June, but they did not reach a compromise.{{sfn|Halecki|1991|pp=236–237}} The Teutonic Order entrusted Vladislaus of Opole with the task of representing their claims to Dobrzyń against Jadwiga.{{sfn|Halecki|1991|p=237}} Jadwiga and her husband met Sigismund of Hungary, who had returned there after his catastrophic defeat in the [[Battle of Nicopolis]], on 14 July.{{sfn|Halecki|1991|pp=236, 238}} They seem to have reached a compromise because Sigismund offered to mediate between Poland, Lithuania and the Teutonic Knights.{{sfn|Halecki|1991|p=240}} On Jadwiga's request, Wenceslaus of Bohemia granted permission for the establishment of a college for Lithuanian students in Prague on 20 July 1397.{{sfn|Halecki|1991|p=247}} Jadwiga, who had spent "many sleepless nights" thinking of this project, according to herself, issued a charter of establishment for the college on 10 November.{{sfn|Halecki|1991|p=247}}

She opened new negotiations with the Teutonic Knights, but Konrad von Jungingen dispatched a simple knight to meet her in May 1398.{{sfn|Halecki|1991|p=241}} Władysław-Jogaila's cousin Vytautas also entered into negotiations with the Teutonic Knights because he wanted to unite Lithuania and Ruthenia under his rule and to receive a royal crown from the Holy See.{{sfn|Halecki|1991|pp=242–243}} According to the chronicle of [[John of Posilge]], who was an official of the Teutonic Order, Jadwiga sent a letter to Vytautas, reminding him to pay the annual tribute that Władysław-Jogaila had granted her as [[dower]].{{sfn|Frost|2015|p=89}}{{sfn|Halecki|1991|pp=243–244}} Offended by Jadwiga's demand, Vytautas sought the opinion of the Lithuanian and Ruthenian lords who refused Jadwiga's claim to a tribute.{{sfn|Frost|2015|p=89}} On 12 October 1398, he signed a peace treaty with the Teutonic Knights, without referring to Władysław-Jogaila's right to confirm it.{{sfn|Halecki|1991|pp=242–243}} Oscar Halecki says that Posilge's "sensational story" is either an invention based on gossip or a guess by the chronicler.{{sfn|Halecki|1991|p=244}}

=== Pregnancy and death (1399) ===
[[File:Nagrobek Jadwigi Andegaweńskiej.jpg|thumb|right|Jadwiga's sarcophagus, [[Wawel Cathedral]], [[Kraków]]]]
Jadwiga was childless for over a decade, which, according to chronicles written in the Teutonic lands, caused conflicts between her and her husband.{{sfn|Halecki|1991|p=245}} She became pregnant in late 1398 or early 1399.{{sfn|Halecki|1991|p=252}} Sigismund, King of Hungary, came to Kraków in early March to negotiate for a campaign to defend [[Wallachia]] against the Ottoman Turks.{{sfn|Halecki|1991|pp=252–253}} Vytautas, in order to bolster his authority over the Rus' principalities, decided to launch an expedition against [[Timur]], who had subdued the [[Golden Horde]].{{sfn|Halecki|1991|pp=256–257}} According to [[Jan Długosz]]'s chronicle, Jadwiga warned the Polish noblemen not to join Vytautas' campaign because it would end in failure.{{sfn|Halecki|1991|pp=256–257}} Halecki says that the great number of Polish knights who joined Vytautas's expedition proves that Długosz's report is not reliable.{{sfn|Halecki|1991|p=257}}

On the occasion of the expected birth to the royal couple, Jogaila's cousin [[Vytautas]], [[Grand Duke of Lithuania]], sent expensive gifts, including a silver cradle, to the royal court on behalf of himself and his wife, [[Anna, Grand Duchess of Lithuania|Anna]].<ref>{{cite web|url=http://www.muzeumhistoriipolski.pl/kalendarium/8/zmarla-jadwiga-krolowa-polski-wywiad-1399-7-17.html|title=Interview about Queen Jadwiga of Poland|access-date=23 December 2011|author=Jadwiga Krzyżaniakowa|language=hu|archive-date=2 April 2012|archive-url=https://web.archive.org/web/20120402214023/http://www.muzeumhistoriipolski.pl/kalendarium/8/zmarla-jadwiga-krolowa-polski-wywiad-1399-7-17.html|url-status=dead}}</ref> The first horoscopes written for Jadwiga's and Jogaila's child predicted a son in mid-September 1398.<ref>Ozog, pp. 135, 322</ref> However, a girl was delivered on 22 June 1399 at [[Wawel Castle]].

The newborn princess was named Elizabeth Bonifacia ({{langx|pl|Elżbieta Bonifacja}}, {{langx|lt|Elżbieta Bonifacija}}), after Jadwiga's mother and Pope Boniface IX who, in a letter of 5 May 1399, had agreed to be godfather under the condition that the infant be called Boniface or Bonifacia. She was baptised by [[Piotr Wysz Radoliński]], [[Bishop of Kraków]].<ref>Wdowiszewski, p. 250</ref> However, the infant died after only three weeks, on 13 July 1399.{{sfn|Frost|2015|p=91}} Jadwiga, too, was on her deathbed. [[Stanisław of Skarbimierz]] expressed hope that she would survive, describing her as the spiritual mother of the poor, weak, and ill of Poland.{{sfn|Brzezińska|1999|pp=407–408}} She advised her husband to marry [[Anna of Cilli]], Casimir the Great's granddaughter{{sfn|Halecki|1991|pp=264–265}}—which he did—and died on 17 July 1399, four days after her newborn daughter.{{sfn|Frost|2015|p=91}}{{sfn|Halecki|1991|p=257}}

Jadwiga and her daughter were buried together in [[Wawel Cathedral]], on 24 August 1399,{{sfn|Frost|2015|p=91}}{{sfn|Halecki|1991|p=257}} as stipulated in the Queen's last will.
