full_context: Document 1: Sigismund Casimir: Sigismund Casimir, Crown Prince of Poland (Polish: "Zygmunt Kazimierz Waza" ), (1 April 1640 – 9 August 1647) - was the only legitimate son of King Władysław IV and his first wife Queen Cecilia Renata. He was named after his grandfather Sigismund III, and uncle John Casimir.
Document 2: Sigismund III Vasa: Sigismund III Vasa (also known as "Sigismund III of Poland", Polish: "Zygmunt III Waza" , Swedish: "Sigismund" , Lithuanian: "Žygimantas Vaza" , English exonym: "Sigmund"; 20 June 1566 – 30 April 1632
Document 3: Saint Casimir: Saint Casimir Jagiellon (Polish: "Kazimierz" , Lithuanian: "Kazimieras" ; October 3, 1458 – March 4, 1484) was a prince of the Kingdom of Poland and of the Grand Duchy of Lithuania. Second oldest son of King Casimir IV, he was tutored by Johannes Longinus, a Polish chronicler and diplomat. After his elder brother Vladislaus was elected as King of Bohemia in 1471, Casimir became the heir apparent. At the age of 13, Casimir participated in the failed military campaign to install him as King of Hungary. He became known for his piousness, devotion to God, and generosity towards the sick and poor. He became ill (most likely with tuberculosis) and died at the age of 25. He was buried in Vilnius Cathedral and his cult grew. His canonization was initiated by his brother King Sigismund I the Old in 1514 and the tradition holds that he was canonized in 1521.
Document 4: Barbara Zápolya: Barbara Zápolya (1495–1515) was Queen of Poland and Grand Duchess of Lithuania as the first wife of King Sigismund I the Old. Marriage to Barbara represented an alliance between Sigismund and the House of Zápolya against the Habsburgs in succession disputes over the throne to the Kingdom of Hungary. The alliance was short-lived as the renewed Muscovite–Lithuanian War forced Sigismund to look for Habsburg allies. The marriage was loving, but short. Barbara was the mother of Hedwig, Electress of Bradenburg, but died soon after the birth of her second daughter Anna.
Document 5: Cecilia Renata of Austria: Archduchess Cecilia Renata of Austria (German: "Cäcilia Renata"; Polish: "Cecylia Renata"; 16 July 1611 – 24 March 1644) was Queen of Poland as consort to the Polish-Lithuanian Commonwealth's King Władysław IV Vasa.
Document 6: War of the Polish Succession (1587–88): The War of the Polish Succession or the Habsburg-Polish War took place from 1587 to 1588 over the election of monarch after the death of King of Poland and Grand Duke of Lithuania Stephen Báthory. The war was fought between factions of Sigismund III Vasa and Maximilian III, with Sigismund eventually being crowned King of Poland and Grand Duke of Lithuania. Two major battles of this conflict included the Siege of Kraków, in which Maximilian III failed to capture the capital of the Commonwealth, and the Battle of Byczyna, in which Maximilian was forced to surrender. Sigismund's victory was significantly the doing of Chancellor and Hetman Jan Zamoyski, who stood behind both the political intrigue and the military victories of this conflict.
Document 7: Constance of Austria: Constance of Austria (German: "Konstanza" ; Polish: "Konstancja" ; 24 December 1588 – 10 July 1631) was queen of Poland as the second wife of King Sigismund III Vasa and the mother of King John II Casimir.
Document 8: Barbara Radziwiłł: Barbara Radziwiłł (Polish: "Barbara Radziwiłłówna" , Lithuanian: "Barbora Radvilaitė" ; 6 December 1520/23 – 8 May 1551) was Queen of Poland and Grand Duchess of Lithuania as consort of Sigismund II Augustus, the last male monarch of the Jagiellon dynasty. Barbara, a great beauty and already widowed, became a royal mistress most likely in 1543 and they married in secret in July or August 1547. The marriage caused a scandal; it was vehemently opposed by Polish nobles, including Queen mother Bona Sforza. Sigismund Augustus, assisted by Barbara's cousin Mikołaj "the Black" Radziwiłł and brother Mikołaj "the Red" Radziwiłł, worked tirelessly to gain recognition of their marriage and to crown Barbara as Queen of Poland. They succeeded and Barbara's coronation was held on 7 December 1550 at Wawel Cathedral. However, her health was already failing and she died just five months later. Even though it was brief, her reign propelled the Radziwiłł family to new heights of political power and influence.

Kasimir Wasa" ; Lithuanian: "Jonas Kazimieras Vaza" ; 22 March 1609 – 16 December 1672) was King of Poland and Grand Duke of Lithuania during the era of the Polish–Lithuanian Commonwealth, Duke of Opole in Upper Silesia, and titular King of Sweden 1648–1660. In Poland, he is known and commonly referred as Jan Kazimierz. His parents were Sigismund III Vasa (1566–1632) and Constance of Austria (1588–1631).

Document 11: Casimir IV Jagiellon: Casimir IV KG (Polish: "Kazimierz IV Andrzej Jagiellończyk" ; Lithuanian: "Kazimieras Jogailaitis" ; 30 November 1427 – 7 June 1492 ) of the Jagiellonian dynasty was Grand Duke of Lithuania from 1440 and King of Poland from 1447, until his death. He was one of the most active Polish rulers, under whom Poland, by defeating the Teutonic Knights in the Thirteen Years' War recovered Pomerania, and the Jagiellonian dynasty became one of the leading royal houses in Europe. He was a strong opponent of aristocracy, and helped to strengthen the importance of Parliament and the Senate.
Document 12: Vladislaus II of Hungary: Vladislaus II, also known as Vladislav II, Władysław II or Wladislas II (1 March 1456 – 13 March 1516; ; Hungarian: "II. Ulászló" ; Polish: "Władysław II Jagiellończyk" ; Croatian: "Vladislav II. Jagelović" ; Slovak: "Vladislav II. Jagelovský" ), was King of Bohemia from 1471 to 1516, and King of Hungary and Croatia from 1490 to 1516. As the eldest son of Casimir IV Jagiellon, he was expected to inherit Poland and Lithuania. George of Poděbrady, the Hussite ruler of Bohemia, offered to make Vladislaus his heir in 1468. Poděbrady needed Casimir IV's support against the rebellious Catholic noblemen and their ally, Matthias Corvinus, king of Hungary. The Diet of Bohemia elected Vladislaus king after Poděbrady's death, but he could only rule Bohemia proper, because Matthias (whom the Catholic nobles had elected king) occupied Moravia, Silesia and Lusatia. Vladislaus tried to reconquer the three provinces with his father's assistance, but Matthias repelled them.
Document 13: Władysław IV Vasa: Władysław IV Vasa (Polish: "Władysław IV Waza" ; Russian: Владислав IV Ваза , "Vladislav IV Vaza" ; Latin: "Vladislaus IV Vasa" or "Ladislaus IV Vasa"; Lithuanian: "Vladislovas Vaza" ; 9 June 1595 – 20 May 1648) was a Polish prince from the Royal House of Vasa.

Orphaned at an early age, she spent her childhood in the court of Holy Roman Emperor Frederick III. As one of the three surviving grandchildren of Emperor Sigismund, she had a strong claim to the kingdoms of Hungary and Bohemia. That made her an attractive bride for a Polish prince. The Polish nobility, seeking to increase Polish influence in Hungary and Bohemia, pursued marriage with Elizabeth since she was born and finally succeeded in 1454. Her marriage to Casimir was one of the most exemplary royal marriages in Poland. She gave birth to thirteen children, eleven of whom survived to adulthood. Four of her sons were crowned as kings.
