In the first years of his government, young Bolesław remained under the strong influence of his mother Salomea and the Voivode Wszebor, who feared the ambition of his elder half-brother High Duke Władysław II (the first-born son of the late duke by his first wife Zbyslava of Kiev

First Part of the conflict with High Duke Władysław II

 was not popular with Wladyslaw, who thought that the land was only temporarily separated from his Dzielnica senioralna and now in its entirety should be returned. Outbreak of civil war was therefore only a matter of time.

The war erupted with full force in 1145, and it seemed that the Junior Dukes were defeated and the High Duke finally achieved the unification of the country. At first the combined forces of Bolesław IV and his brothers prevented the disaster and demanded a hasty reorganization of the forces of Władysław at the Battle on the Pilicą River. The major significance of this battle was to the former voivode Wszebor, whose military experience far exceeded the ability of Władysław's commanders. Soon, however, the situation was totally reversed as a result of the Kievan troops who entered in the country as Władysław's allies. Bolesław then had to agree to step down and renounce any pretension over the lands belonging to his mother.

The concessions of the Junior Dukes ultimately didn't resolve the problem. Moreover, Władysław's confidence in his forces had him embark on a final solution, the removal of his stepbrothers from their lands. Suddenly, the Junior Dukes could rely on the support of the High Duke's all-powerful voivoide Piotr Włostowic, for whom Władysław's plans were too radical and threatened to weaken his position. While Władysław opted for a quick response against him (the voivode was blinded and muted), forcing Włostowic to go to Kiev

, the High Duke's final decision on his confrontation with the voivode considerably weakened his position. What's more, Włostowic convinced the Kievans to break his alliance with Władysław.

Władysław II is expelled from the country. Bolesław IV, High Duke of Poland

At the beginning of 1146 the rebellions against Władysław's government rose mighty, sparked by the fate of Piotr Włostowic. Nevertheless, the final victory of Władysław seemed likely, especially after the conquest of Masovia (forcing Bolesław to escape) and the siege of Poznan

The whole efforts and attempts to acquire these province were finally defeated in 1166. Furthermore during one of the battles the younger brother of the High Duke, Henry of Sandomierz, was killed.

Rebellion of Casimir II the Just. Relations with the Silesian Dukes

After Henry's death, against the dispositions of the Bolesław III's Testament, the High Duke incorporated Sandomierz into the Seniorate Province. This caused the anger and frustration of his youngest brother, Casimir II the Just, who was the next in line to inherit the lands and was the only of Bolesław III' sons still without any land.

Casimir was supported in his rebellion by his elder brother Duke Mieszko III the Old of Greater Poland, the magnate Jaksa of Miechów and Sviatoslav, son of Voivode Piotr Włostowic, as well as the Archbishops of Gniezno and Kraków; also, almost all Leeser Polish

, and there they proclaimed Mieszko III as the new High Duke and Casimir was formally invested with Sandomierz. But at the end Bolesław maintained his rule by largely accepting the demands of rebels; he divided late Henry's duchy in three parts: the lands of Wiślica

 were granted to Casimir, Bolesław himself obtained Sandomierz proper and the rest passed to Mieszko III.

After the disaster of the Prussian Crusade, the Silesian dukes Bolesław I the Tall and Mieszko IV Tanglefoot attempted to dethrone the High Duke and to recover the Seniorate Province and thereby the Polish overlordship. Bolesław's reprisal expedition in the following year ended with a total disaster, so the High Duke eventually had to reconcile with his Silesian nephews.

In 1172 Duke Mieszko III rebelled again; this time supporting his grandnephew Jarosław of Opole (the eldest son of Bolesław I the Tall), who, forced to become a priest in his early years, was barred from the Silesian succession. Unsatisfied with this, Jarosław tried to gain power and obtain his own lands. The support of this rebellion was so strong, that his father was forced to escape to Erfurt

. This originated another expedition in his aid by Emperor Frederick Barbarossa, who again invaded Poland and defeated the rebels. The High Duke ordered Mieszko III to Magdeburg where peace was made with the Empire after the payment of 8,000 pieces of silver and the Silesian duchy was again granted to Bolesław I the Tall at the Emperor's mercy; despite his victory, the High Duke finally accepted the autonomy of his Silesian nephews.

Shortly afterwards another rebellion took place, this time of the Lesser Polish nobles, who were extremely dissatisfied with the harsh and dictatorial High Duke's government. The rebels invited Casimir II, then Duke of Wiślica, to take the Kraków throne, but Bolesław's resistance against his younger brother was so strong that both parties made concessions, who led finished with any riots until the end of the High Duke's reign. Casimir succeeded Bolesław in Sandomierz upon his death in 1173 and became High Duke four years later.

Relations with the Church

Bolesław was also known for his many gifts and grants to the Church. Particularly enriched thanks to him, among others were: the Church of St. Mary and St. Catherine and of St. Vincent near Wrocław, the Benedictine monastery in Trzemeszno
