¿Quién se casó con Радзивилл, Барбара?

Ба́рбара Радзиви́лл (Варва́ра Радзиви́лл, бел. Барбара Радзівіл, пол. Barbara Radziwiłłówna, 6 декабря 1520, Вильна — 8 мая 1551, Краков) — королева польская и великая княгиня литовская, наследница владений Гаштольдов. Жена Станислава Гаштольда, а затем великого князя литовского и короля польского Сигизмунда II Августа.

Stanislovas Goštautas (also called Stanisław Gasztołd or Gasztołt of Abdank in Polish) (ca. 1507 in Vilnius – 1542) was a member of the Lithuanian nobility and a high-ranking member of the Lithuanian administration. Born to Albertas Goštautas, the Voivode of Vilnius and Princess Sofia of Vereya, he was the last direct male descendant of the – once mighty – Goštautai family.

A prominent member of the Grand Duchy's administration in the early times of the Polish–Lithuanian union, Goštautas held a number of important posts in the state's administration. Among others, since 1522 he held the post of the voivode of Navahrudak, although he did not rise to that office until 1530. Since 1542 he was also a voivode of Trakai. As one of the most notable and influential noblemen of his epoch, in 1542 he was also awarded with a royal pension of 600 times the number of 60 Prague groschen in exchange for his town of Upytė, which was bought by Sigismund Augustus of Poland.

On 17 May 1537 he married Barbara Radziwiłł, later the second wife of the Grand Duke of Lithuania and King of Poland Sigismund II Augustus. Goštautas died on 18 December 1542, leaving some of his family fortune to his wife, who later might have passed it on to her branch of the Radziwiłł family, while the bulk of his estates was taken by the Grand Duke of Lithuania Sigismund II Augustus, as a matter of sovereign's right.

Sigismund II Augustus (Polish: Zygmunt II August, Lithuanian: Žygimantas Augustas; 1 August 1520 – 7 July 1572) was King of Poland and Grand Duke of Lithuania, the son of Sigismund I the Old, whom Sigismund II succeeded in 1548. He was the first ruler of the Polish–Lithuanian Commonwealth and the last male monarch from the Jagiellonian dynasty.

Sigismund was elder of two sons of Italian-born Bona Sforza and Sigismund the Old, and the only one to survive infancy. From the beginning he was groomed and extensively educated as a successor. In 1529 he was chosen as king in vivente rege election while his father was still alive. Sigismund Augustus continued a tolerance policy towards minorities and maintained peaceful relations with neighbouring countries, with the exception of the Northern Seven Years' War which aimed to secure Baltic trade. Under his patronage, culture flourished in Poland; he was a collector of tapestries from the Low Countries and collected military memorabilia as well as swords, armours and jewellery. Sigismund Augustus' rule is widely considered as the apex of the Polish Golden Age; he established the first regular Polish navy and the first regular postal service in Poland, known today as Poczta Polska. In 1569, he oversaw the signing of the Union of Lublin between Poland and the Grand Duchy of Lithuania, which formed the Polish–Lithuanian Commonwealth and introduced an elective monarchy.

Sigismund Augustus married three times; his first wife, Elizabeth of Austria, died in 1545 at just eighteen. He was then involved in several relationships with mistresses, the most famous being Barbara Radziwiłł, who became Sigismund's second wife and Queen of Poland in spite of his mother's disapproval. The marriage was deemed scandalous and was fiercely opposed by the royal court and the nobility. Barbara died five months after her coronation, due to heavy illness. Sigismund finally wedded Catherine of Austria. Neither marriage resulted in living children.

Sigismund Augustus was the last male member of the Jagiellonian dynasty. Following the death of his sister Anna in 1596 the Jagiellonian dynasty came to an end.
