Janusz was the younger son of
Konrad III Rudy and Anna Radziwiłł, born in winter 1502. After his father's death in 1503 Janusz and his brother Stanisław inhertited theCzersk Land , and with support ofAlexander Jagiellon , the throne ofDuchy of Masovia , but due to their young age the throne was taken by their mother, Anna, who became theregent .In 1518, both brothers were invited to the wedding of
Sigismund I the Old andBona Sforza . Janusz and Stanisław fought on the Polish side during thePolish-Teutonic War (1519–1521) .Anna reigned until 1518, past the time both brothers reached the age in which they could became rulers. Eventually the disapproval of local nobility resulted in her officially transferring the power to her sons, but in fact she continued to rule the Duchy until 1522.
After their mother's death, both brothers quickly became known for their love of "women and wine". Both brothers acted as co-rulers until Stanisław's death in 1524. However Janusz ruled only until his death in the night of 9 to 10 March, 1526. He was buried in the
St. John's Cathedral, Warsaw . With his death, the male line of Masovian Piasts - originating fromSiemowit III of Masovia - died out.The death of both brothers caused unrest, as accusations that they were murdered became widespread. Eventually king Sigismund himself looked into the matter, and concluded that there was no foulplay. A contemporary historian,
Marcin Bielski , suggested that both brothers died due toalcohol poisoning ; others suggestedtuberculosis .Soon after his death, the
Duchy of Masovia wasannexed into the kingdom of Poland, despite resistance from some of the Masovian nobility. They tried to retain their independence and argued that the Duchy should be inherited by the female relatives (such asAnna of Masovia ). The Polish king refused to recognize their demands, and stood by the agreements that made him the heir to the Duchy, reuniting it with Poland. The Duchy, which would became a significant asset of the PolishJagiellon dynasty , would retain some autonomy till 1576.
