In 1310 he offered some of Masovia to his son (the Duchy of Warsaw and the Duchy of Czersk).
At first it was part of another Polish fiefdom, the Duchy of Masovia, as in 1388 the king of Poland, Władysław Jagiełło, granted Belz to Siemowit IV, Duke of Masovia, for his recognition of Masovia as a fiefdom of Poland and as a dowry for Siemowit's marriage with Jagiełło's sister, Alexandra.
The first waves of Slavic migration settled the area of the upper Vistula River and elsewhere in the lands of present-day southeastern Poland and southern Masovia, coming from the upper and middle regions of the Dnieper River.
In 1374 he inherited Zakroczym and in 1381 the lands of Czersk, Liw and Wyszogród as the result of partition of Masovia between his younger brother Siemowit IV and himself.

When his father died in 1313 he inherited parts of Warsaw and Liw in addition to his duchy, which allowed Trojden to reign over Eastern Masovia.
