Elizabeth Szilágyi
Erzsébet Szilágyi( c. 1410–1483) was a Hungarian noblewoman, spouse of John Hunyadi and mother of Matthias Corvinus, King of Hungary.
Elizabeth was the daughter of the Ladislaus Szilágyi and Catherine Bellyéni, members of two influential Hungarian families of the 15th century that were loyal to the King Sigismund of Hungary.
She had several siblings, including Mihály Szilágyi, who had an important role after the death of Elizabeth's husband, John Hunyadi.
Hunyadi was the regent of the Kingdom of Hungary and supreme commander of the armies, an excellent fighter, that counted with the favor of the Pope for confronting the Ottoman Empire.
He was the most powerful nobleman of the Kingdom and counted with huge properties and centenars of lower noblemen that supported him.
After his death in 1456, his older son Ladislaus Hunyadi became the head of the House of Hunyadi, however after murdering the count Ulrich von Cilli, the counselor of the King Ladislaus V of Hungary, he was executed.
Then Elizabeth's only son Matthias Corvinus of Hungary was taken to Prague by the young King, who felt for his life before the instability caused after the execution of Ladislaus Hunyadi.
Mihály Szilágyi and Elizabeth founded Szilágyi – Hunyadi Liga and became the leaders of this Liga, and after the sudden death of the King Ladislaus( possibly poisoned), she negotiated the release of Matthias, who was soon elected as King of Hungary in 1458.
After this, Elizabeth became the mother of the King, and continued being a great influence in the Kingdom.
Matthias had an illegitimate son in 1473, and soon was sent to the properties of his grandmother, who raised him with the best teachers of the Kingdom.
The illegitimate John Corvinus never became King of Hungary after the death of Matthias because of the pression of the noblemen and the widow of the monarch, but enjoyed titles and properties, fighting the Turkish armies until the end of his life as his grandfather and father did before.
His grandmother Elizabeth lived in Óbuda most of his life, and founded several monasteries and chapels, following her deeply religious beliefs.
She died around 1483.

He was the last male of the senior Angevin line.
He was named in honor of the King Saint Ladislaus I of Hungary, who was highly venerated by the Angevin Kings Charles I of Hungary and Louis I of Hungary, considered the model of the perfect King, Knight, and Christian man in Central Europe during that time.
Ladislaus of Naples became a skilled political and military leader, protector and controller of Pope Innocent VII; however, he earned a bad reputation concerning his personal life.
He profited from disorder throughout Italy to greatly expand his kingdom and his power, appropriating much of the Papal States to his own use.
Moreover, he murdered many of his enemies.
Ladislaus I of Hungary
Ladislaus I or Ladislas I, also Saint Ladislaus or Saint Ladislas (1040 – 29 July 1095) was King of Hungary from 1077 and King of Croatia from 1091.
He was the second son of King Béla I of Hungary.
After Béla's death in 1063, Ladislaus and his elder brother, Géza, acknowledged their cousin, Solomon as the lawful king in exchange for receiving their father's former duchy, which included one-third of the kingdom.
They cooperated with Solomon for the next decade.
Ladislaus's most popular legend, which narrates his fight with a "Cuman" (a Turkic nomad marauder) who abducted a Hungarian girl, is connected to this period.
The brothers' relationship with Solomon deteriorated in the early 1070s, and they rebelled against him.
Géza was proclaimed king in 1074, but Solomon maintained control of the western regions of his kingdom.
During Géza's reign, Ladislaus was his brother's most influential adviser.
Géza died in 1077, and his supporters made Ladislaus king.
Solomon resisted Ladislaus with assistance from King Henry IV of Germany.
Ladislaus supported Henry IV's opponents during the Investiture Controversy.
In 1081, Solomon abdicated and acknowledged Ladislaus's reign, but he conspired to regain the royal crown and Ladislaus imprisoned him.
Ladislaus canonized the first Hungarian saints (including his distant relatives, King Stephen I and Duke Emeric) in 1085.
He set Solomon free during the canonization ceremony.
After a series of civil wars, Ladislaus's main focus was the restoration of public safety.
He introduced severe legislation, punishing those who violated property rights with death or mutilation.
He occupied almost all Croatia in 1091, which marked the beginning of an expansion period for the medieval Kingdom of Hungary.
Ladislaus's victories over the Pechenegs and Cumans ensured the security of his kingdom's eastern borders for about 150 years.
His relationship with the Holy See deteriorated during the last years of his reign, as the popes claimed that Croatia was their fief, but Ladislaus denied their claims.
Ladislaus was canonized on 27 June 1192 by Pope Celestine III.
Legends depict him as a pious knight-king, "the incarnation of the late-medieval Hungarian ideal of chivalry.
" He is a popular saint in Hungary and neighboring nations, where many churches are dedicated to him.

Béla settled in Poland and married Richeza (or Adelaide), daughter of King Mieszko II of Poland.
He returned to his homeland upon the invitation of his brother Andrew, who had in the meantime been crowned King of Hungary.
Andrew assigned the administration of the so-called "ducatus" or "duchy", which encompassed around one-third of the territory of the Kingdom of Hungary, to Béla.
The two brothers' relationship became tense when Andrew had his own son, Solomon, crowned king, and forced Béla to publicly confirm Solomon's right to the throne in 1057 or 1058.
Béla, assisted by his Polish relatives, rebelled against his brother and dethroned him in 1060.
He introduced monetary reform and subdued the last uprising aimed at the restoration of paganism in Hungary.
