He was the eldest son of the Polish king Bolesław the Brave, but was deprived of the succession by his father, who around 1001 sent him to Italy in order to become a monk at one of Saint Romuald's hermitages in Ravenna.

[1] Due to tradition and the impossibility of determining the correct version of the name, Bezprym remains the form used, although, according to K. Jasiński, it probably requires modifications.

Marian Gumowski also suggested, on the basis of numismatic research, that this "combined" prince could have governed the Duchy of Bohemia in 1003.

[5] Though opinions vary about the actual identity of Bolesław I 's second wife, there are a number of researchers who still support the hypothesis that she was a daughter of Géza.

This probably showed that his father disliked him and considered Mieszko II as his successor since his birth, which was confirmed by Bolesław I's later political activity.

Bezprym took refuge in Kievan Rus' and probably used the weakened position of Mieszko II as an excuse to gain the alliance of the Rurikid rulers Yaroslav I the Wise and Mstislav.

It has been postulated that Yaroslav I's troops intervened directly in the central provinces of Poland, aimed at embedding the new Duke on the throne, but this is now considered doubtful.

At the court of Emperor Conrad II, the deposed queen was received with all honors, and was also allowed to continue to use her royal title.

Perhaps among the victims of the repression were two bishops, Roman and Lambert, whose date of death was recorded in 1032 in the Chronicles of the Chapter of Kraków.

The brutal fight with the opposition could have led to the above-mentioned Pagan Reaction, but it was probably instigated by discontent against the power of the Church and with the state apparatus.

Mainly it was a reflection of the economic situation caused by the aggressive policy of Bolesław I the Brave and the less successful rule of Mieszko II.

The defeat in the battle in the west during that period cut off the basic source of livelihood of the Polish troops, who were forced to loot the western lands.

Probably the instigators of his death were his half-brothers, although the main conspirator was thought to be Otto, who remained free in Germany.
