Wer datete Sigismund II. August?

Sigismund II. August (polnisch Zygmunt II. August, litauisch Žygimantas Augustas; * 1. August 1520 in Krakau, Polen; † 7. Juli 1572 in Knyszyn, Polen) war ab 1529 als Sigismund III. Großfürst von Litauen, ab 1530 als Sigismund II. König von Polen und ab 1548, nach dem Tod seines Vaters, Alleinherrscher. Er war ab 1569 der erste Regent des unierten Staates Polen-Litauen.

Barbara Giza (Polish: Barbara Gizanka; c. 1550 – May 1589), was a mistress of King Sigismund II Augustus of Poland during 1570–72. She was a daughter of a Warsaw burgher Jan Giza, a merchant and usurer, and his wife Anna, whose origins are unknown.

Barbara was a Protestant, and she is sometimes given credit for influencing the King towards religious tolerance of Protestants.

Near the end of King Sigismund II Augustus' life, after the death of his wife, he expressed a desire to marry Barbara with the hope of producing an heir. However, he died before a marriage could take place.
