After Henry's death his eldest son Bolesław II the Bald followed him as ruler of Lower Silesia until in 1248 his younger brother Henry III the White came of age and claimed his rights of succession.
Backed by the nobility of Wrocław, Henry III forced the duke to cede central parts of Lower Silesia to him, while Bolesław himself retired to Legnica.
Furthermore, he came into conflict with his younger brother Konrad, who, originally predestined for an ecclesiastical career as Bishop of Passau, also demanded his distributive share and had to be paid off by Bolesław with the newly created Duchy of Głogów in 1251.

Nevertheless, Bolesław's son Henry V the Fat, who succeeded his father in 1278, was able to enlarge the duchy's territories by defeating his cousin Henry Probus, Duke of Wrocław, and, with support of King Wenceslaus II of Bohemia succeeded him as duke in 1290.
Thus, the Lower Silesian duchies of Legnica and Wrocław were re-reunited until 1311.

As after the death of Henry V in 1296 his eldest son Bolesław III the Generous was still a minor, King Wenceslaus took over his guardianship, strengthening the Bohemian influence in Silesia.
In 1303 Bolesław III was betrothed to Wenceslaus' daughter Margaret and to no avail tried to follow the extinct Přemyslid dynasty on the Bohemian throne in 1306.
He was not able to retain the united duchy and in 1311 Lower Silesia was split again, with Wrocław going to his younger brother Henry VI the Good.
Even Bolesław's rule over Legnica was contested by his brother Władysław and in 1329 he had to pay homage to the Bohemian King John of Luxembourg to secure his reign.

As the duchy's capital at the beginning of the 14th century, Legnica was an important city of Central Europe, with a population of approximately 16,000 residents.
The city began to expand quickly after the discovery of gold in the Kaczawa.
