Queen and Regent
Given her illustrious family connections, it is not surprising that Mary would be thrust into the political world of Renaissance Europe, but she became more than just a queen by virtue of a political marriage; she became an important ruler in her own right.
As the daughter of Juana, Queen of Castile, and Philip of Burgundy, the only son of Maximilian I, the Holy Roman Emperor, Mary was born into the most powerful dynasty of the Renaissance.

When she was only an infant, Mary was promised in marriage to the yet unborn heir to the throne of Hungary and Bohemia. The expected male heir arrived, though prematurely, so his physicians put him in an incubator of freshly killed pigs to keep him warm.

This union between the Hapsburgs and the Hungarian and Bohemian Crown was further cemented with a marriage between Mary's brother Ferdinand and Louis's sister Anna. Politically advantageous marriages were also arranged for Mary's three sisters: Isabel was married to Christian II of Denmark; Eleanor was the queen of Francis I of France; and Catherine was the bride of John III of Portugal. Mary's two brothers were destined for even greater positions of power: Ferdinand as the Archduke of Austria and Charles as Europe's most powerful leader, the Holy Roman Emperor Charles V.
