Janusz I. Starszy (Janusz I "the Elder"; * approx. 1346 ; † December 8, 1429 in Czersk ) was Duke of Mazovia in Warsaw from 1373/1374 , and from 1381 by dividing the estate, he was also Lord of Nur , Łomża , Liw , Ciechanów , Wyszogród , Zakroczym and Podlachia .
As Duke of Mazovia he was a vassal of the Polish crown and came from the Mazovian line of the Piasts.
Janusz I was the eldest son of Duke Siemowit III. of Mazovia. His brother was Siemowit IV .
Polish politics
In his politics, Janusz I stuck to the close cooperation with Poland and his subsequent rulers Ludwig I of Anjou , Hedwig of Anjou and Władysław II Jagiełło . In this way Janusz I protested against the policy of his brother Siemowit IV, with which he wanted to win the Polish crown for himself. After the death of Kasimir “the Great” he handed over the Polish crown directly to Louis I, King of Hungary and Croatia and nephew of the last Piast from the line of the Kujavian Piasts on the Polish throne.
Janusz I and the German Order
The friendly relations between Poland and Lithuania after the decision of the union resulted in the permanent state of hostility on the part of the Teutonic Order . In 1393, for unknown reasons, the prince was kidnapped in connection with the construction of his castle on the Mazovian border near the Narew river by Commander Rudolf on behalf of Grand Master Konrad von Jungingen . King Władysław II Jagiełło intervened and the Teutonic Order released him again. In 1404, the knights of the order kidnapped Duke Janusz I with his wife and sons again. Here too, King Władysław II Jagiełło's second intervention brought about the release of the Duke of Mazovia. In 1409 Komtur Ostróda and Komtur Brandenburg went to the Principality of Janusz I.
