Joanna of Castile
Joanna (6 November 1479 – 12 April 1555), known historically as Joanna the Mad , was Queen of Castile from 1504, and of Aragon from 1516.
Modern Spain evolved from the union of these two crowns.
Joanna was married by arrangement to Philip the Handsome, Archduke of the House of Habsburg, on 20 October 1496.
Following the deaths of her brother, John, Prince of Asturias, in 1497, her elder sister Isabella in 1498, and her nephew Miguel in 1500, Joanna became the heir presumptive to the crowns of Castile and Aragon.
When her mother Queen Isabella I of Castile died in 1504, Joanna became Queen of Castile, while her father, King Ferdinand II of Aragon, proclaimed himself 'Governor and Administrator of Castile'.
In 1506 Archduke Philip became King of Castile "jure uxoris", initiating the rule of the Habsburgs in the Spanish kingdoms, and died that same year.
Despite being the ruling Queen of Castile, she had little effect on national policy during her reign as she was declared insane and imprisoned in Tordesillas under the orders of her father, who ruled as regent until his death in 1516, when she inherited his kingdom as well.
From 1516, when her son Charles I ruled as king, she was nominally co-monarch but remained imprisoned until her death.

Andrew III of Hungary
Andrew III the Venetian( 126514 January 1301) was King of Hungary and Croatia between 1290 and 1301.
His father, Stephen the Posthumous, was the posthumous son of Andrew II of Hungary although Stephen's brothers considered him a bastard.
Andrew grew up in Venice, and first arrived in Hungary upon the invitation of a rebellious baron, Ivan Kőszegi, in 1278.
Kőszegi tried to play Andrew off against Ladislaus IV of Hungary, but the conspiracy collapsed and Andrew returned to Venice.
Being the last male member of the House of Árpád, Andrew was elected king after the death of King Ladislaus IV in 1290.
He was the first Hungarian monarch to issue a coronation diploma confirming the privileges of the noblemen and the clergy.
At least three pretenders — Albert of Austria, Mary of Hungary, and an adventurer — challenged his claim to the throne.
Andrew expelled the adventurer from Hungary and forced Albert of Austria to conclude a peace within a year, but Mary of Hungary and her descendants did not renounce their claim.
The Hungarian bishops and Andrew's maternal family from Venice were his principal supporters, but the leading Croatian and Slavonian lords were opposed to his rule.
Hungary was in a state of constant anarchy during Andrew's reign.
The Kőszegis, the Csáks, and other powerful families autonomously governed their domains, rising up nearly every year in open rebellion against Andrew.
With Andrew's death, the House of Árpád became extinct.
A civil war ensued which lasted for more than two decades and ended with the victory of Mary of Hungary's grandson, Charles Robert.
Mary of Hungary (governor of the Netherlands)
Mary of Austria (15 September 1505 – 18 October 1558), also known as Mary of Hungary, was queen consort of Hungary and Bohemia as the wife of King Louis II, and was later Governor of the Habsburg Netherlands.
The daughter of Queen Joanna and King Philip I of Castile, Mary married King Louis II of Hungary and Bohemia in 1515.
Their marriage was happy but short and childless.
Upon her husband's death following the Battle of Mohács in 1526, Queen Mary governed Hungary as regent in the name of the new king, her brother, Ferdinand I.
Following the death of their aunt Margaret in 1530, Mary was asked by her eldest brother, Emperor Charles V, to assume the governance of the Netherlands and guardianship over their nieces, Dorothea and Christina of Denmark.
As governor of the Netherlands, Mary faced riots and a difficult relationship with the Emperor.
Throughout her tenure she continuously attempted to ensure peace between the Emperor and the King of France.
Although she never enjoyed governing and asked for permission to resign several times, the Queen succeeded in creating a unity between the provinces, as well as in securing for them a measure of independence from both France and the Holy Roman Empire.
After her final resignation, the very frail Queen moved to Castile, where she died.
Having inherited the Habsburg lip and not very feminine looks, Mary was not considered physically attractive.
Her portraits, letters, and comments by her contemporaries do not assign her the easy Burgundian charm possessed by her grandmother, Duchess Mary of Burgundy, and her aunt Margaret.
Nevertheless, she proved to be a determined and skillful politician, as well as an enthusiastic patron of literature, music, and hunting.
