Bolesław's son Władysław II received the Duchy of Silesia and, as the eldest, was also granted the title of a High Duke among with the Seniorate Province. Nevertheless, after he had tried to gain control over all Poland, he was banned and expelled by his younger half-brothers in 1146. Bolesław's second eldest son Bolesław IV the Curly, Duke of Masovia, became Polish High Duke. When, in 1163, Władysław's three sons, backed by Emperor Frederick I Barbarossa returned to Poland, Bolesław IV had to restore their heritage.
After ten years of joint rule, Władysław's sons finally divided Silesia in 1173:
Bolesław I the Tall, the eldest, received the core territory around the residences of Wrocław, Legnica and Opole. In 1180, he granted the Duchy of Opole to his son Jarosław, who ruled until his death in March 1201. Upon Bolesław's death in December 1201, his lands were inherited by his only remaining son Henry I the Bearded.
Konrad Spindleshanks (Konrad Laskonogi), the youngest, in 1177 also claimed his rights and received the Duchy of Głogów from his brother Bolesław, who after Konrad's death about 1180/90 again inherited it.

After his brother Bolesław I had died, Mieszko I Tanglefoot also conquered and took the Duchy of Opole from his nephew Henry I the Bearded. He ruled over the Racibórz and Opole duchies, which emerged as Upper Silesia, until his death in 1211. Henry I the Bearded remained sovereign of the Lower Silesian Duchy of Wrocław, he acquired the Greater Polish lands of Kalisz in 1206, which he granted to his Piast cousin Władysław Odonic, as well as Lubusz Land in 1210. High Duke of Poland from 1232, he conquered further Greater Polish territories around Santok in 1234.
Mieszko's heir was Duke Casimir I of Opole, who died in 1230. Thereupon, Henry I managed to reunite whole Silesia under his reign. He was succeeded by his son Henry II the Pious in 1238, while Upper Silesia was inherited by Casimir's son Mieszko II the Fat in 1239. He and his younger brother, Władysław Opolski, had already received Greater Polish Kalisz in 1234.
Henry II was killed at the Battle of Legnica in 1241. His eldest son and heir, Duke Bolesław II the Bald temporarily gave Lubusz Land to his younger brother Mieszko († 1242). He reconciled with his Greater Polish cousin Duke Przemysł I and finally returned Santok in 1247 and remained sole ruler of Lower Silesia until 1248.
Mieszko II the Fat, of Upper Silesia, in 1244, returned Kalisz to Duke Przemysł I of Greater Poland. He died in 1246 and his possessions were inherited by his brother Władysław Opolski.
In 1327, King John I of Bohemia began accepting the fealty of the Silesian dukes as part of his claim on the Polish crown. At the Treaty of Trentschin on 24 August 1335 it was agreed that John would abandon his claim and in return receive the suzerainty of the Silesian duchies and a one-time payment (20,000 threescores of Prague groschen). This was finalized at the Congress of Visegrád in the same year, although some Piast-ruled duchies remained outside of Bohemian suzerainty until 1392.
Under the Bohemian crown, the duchies continued to be ruled by branches of the Piast dynasty known as the Silesian Piasts until their last lineage died out in 1675. When a ducal lineage died out, the duchy passed to the crown and became a state country.
Henry II the Pious was Duke of Silesia and High Duke of Poland as well as Duke of South-Greater Poland from 1238 until his death. Between 1238 and 1239 he also served as regent of Sandomierz and Opole–Racibórz. He was the son of Henry the Bearded and a member of the Silesian Piast dynasty. In October 2015, the Roman Catholic Diocese of Legnica opened up his cause for beatification, obtaining him the title of Servant of God.
The Duke of Silesia was the sons and descendants of the Polish Duke Bolesław III Wrymouth. In accordance with the last will and testament of Bolesław, upon his death his lands were divided into four or five hereditary provinces distributed among his sons, and a royal province of Kraków reserved for the eldest, who was to be High Duke of all Poland. This was known as the fragmentation of Poland. Subsequent developments lead to further splintering of the duchies.
The Duchy of Greater Poland was a district principality in Greater Poland that was a fiefdom of the Kingdom of Poland. It was formed in 1138 from the territories of the Kingdom of Poland, following its fragmentation started by the testament of Bolesław III Wrymouth. In 1177, the state broke had separated into the duchies of Poznań, Gniezno and Kalisz, and united again in 1279, lasting in that form until 1320, when it was incorporated back into the Kingdom of Poland. Its capital was Poznań.

The Duchy of Silesia with its capital at Wrocław was a medieval duchy located in the historic Silesian region of Poland. Soon after it was formed under the Piast dynasty in 1138, it fragmented into various Silesian duchies. In 1327, the remaining Duchy of Wrocław as well as most other duchies ruled by the Silesian Piasts passed to the Kingdom of Bohemia as Duchies of Silesia. The acquisition was completed when King Casimir III the Great of Poland renounced his rights to Silesia in the 1335 Treaty of Trentschin.

The Duchy of Bytom or Duchy of Beuthen was one of many Silesian duchies.

The duchy's capital was Bytom (Beuthen), formerly part of Lesser Poland until in 1177 the Polish High Duke Casimir II the Just had attached it to the Silesian Duchy of Racibórz.
The Silesian Piasts were the elder of four lines of the Polish Piast dynasty beginning with Władysław II the Exile (1105–1159), eldest son of Duke Bolesław III of Poland. By Bolesław's testament, Władysław was granted Silesia as his hereditary province and also the Lesser Polish Seniorate Province at Kraków according to the principle of agnatic seniority.
The Duchy of Nysa or Duchy of Neisse was one of the duchies of Silesia with its capital at Nysa in Lower Silesia.
