Between 1000 and 1011 CE, East Central Europe—encompassing present-day Poland, Czechia, Slovakia, Hungary, and the eastern parts of Germany and Austria east of 10°E and north of the previously defined southeastern boundary—experienced pivotal transformations. This era witnessed the formal recognition of Polish sovereignty with Bolesław I’s coronation-like elevation, the foundation and official Christianization of the Kingdom of Hungary under Stephen I, and sustained imperial influence from the late Ottonian emperors, particularly Otto III and Henry II. These critical events fundamentally reshaped the region’s medieval political and cultural landscape.

Boleslaus's kinsman Vladivoj, probably a Přemyslid, or their distant relative, had taken the Bohemian throne, but he is a drunk and dies within a year.
After Vladivoj's death, the nobles invite Boleslaus’s brothers Jaromir and Oldrich from exile, but Jaromir is unable to secure the throne.
Boleslaus the Red, with armed support from Boleslaw the Brave of Poland, is restored to authority on February 9, 1003.
Jaromír and Oldřich flee to Germany and place themselves under the protection of Henry II.
Jaromír‘s promise, made at Merseburg, to hold Bohemia as a vassal of Henry definitively places Bohemia within the jurisdiction of the Holy Roman Empire.
The duke soon undermines his own position by ordering a massacre of the Vršovci, his leading nobles, at Vyšehrad.
According to Thietmar, Boleslaus slashes to death his son-in-law with his own sword.
The tragedy occurs during Lent.

Long-Term Consequences and Historical Significance
The era 1012–1023 CE significantly shaped medieval East Central Europe, with Bolesław’s Poland reaching its territorial peak, Stephen I establishing firm foundations for a unified Hungarian monarchy, and Bohemia enduring critical dynastic turmoil. These developments solidified regional political identities, expanded cultural influence, and strengthened the institutional frameworks central to the High Medieval history of East Central Europe.
Jaromír, the second son of Bohemian duke Boleslaus II the Pious and Emma of Melník, had rebelled in 1003 against his elder brother Boleslaus III, who had had him emasculated, but was unable to secure the throne, which had subsequently been taken by Boleslaw the Brave, King of Poland.
Jaromír and his brother Oldrich had then sought military backing from the German King Henry II.
At Merseburg, Jaromír had promised to hold Bohemia as a vassal of Henry, placing the country definitively within the jurisdiction of the Holy Roman Empire.
Jaromír had occupied Prague with a German army in 1004 and made himself Duke.
The state he has regained is a small one, as Polish forces still hold Moravia, Silesia, and Lusatia.
Jaromír's reign—like so many of the other early Czech rulers—has been a struggle to regain the lost lands.
On April 12, 1012, Jaromír is dethroned by Oldrich and forced once again into exile.
Oldrich recognizes the suzerainty of the Holy Roman Emperor.
According to legend, Oldrich married a woman known as Božena, daughter of Kresina, after discarding his first wife on the grounds that they were childless.
Judith of Schweinfurt, whose parents were Henry, Margrave of Nordgau (Bavaria), and his wife Gerberga, is a scion of the House of Babenberg.
The House of Premysl wished to confirm its good relationship with the Babenbergs through a marriage to Judith in 1020.
Judith was a desirable bride, but Oldrich of Bohemia had only one son, Bretislaus, and he was of illegitimate birth, thus complicating the prospect of a marriage with the highborn Judith.
Bretislaus had solved the problem by kidnapping Judith from a monastery, although he is never punished for the crime.
He had married Judith some time later.
Their first son, Spytihněv, was born after almost ten years, which led to the hypothesis that the kidnapping happened in 1029, although Judith may have given birth to daughters before her first son.
Oldrich and his son Bretislaus had sought to win back Moravia from the Poles and in 1029 Bretislaus had driven the Poles out of the eastern lands.
Bretislaus' efforts in today’s Slovakia against Hungary had failed in 1030 due to the jealousy of the Emperor Conrad II.
In the following year, Czech forces refuse to take the field for the emperor.
Oldrich had been invited to the Diet of Merseburg in 1032 and had not appeared.
His absence had raised the ire of the emperor and Conrad, busy with events in Burgundy, charges his son Henry VI, Duke of Bavaria, with punishing the recalcitrant Bohemian.
Jaromír, twice Duke of Bohemia and twice deposed, manages, in a surprise campaign, to depose his brother in 1033.
Oldrich is sent to Bavaria.
Jaromír’s third reign is short-lived.
He is in turn was captured, blinded, and deposed by Oldrich, who seizes power again and drives out Jaromír's son from Moravia.
Oldrich dies abruptly on November 11, 1034 and later examination of his skeleton reveals his skull to have suffered a fatal blow.
Jaromír now renounces the throne in favor of Bretislaus, called the Restorer, who had fled beyond the Bohemian border.
Jaromír, who has been imprisoned at Lysá nad Labem and dies (assassinated by one of the Vršovci) on November 6, 1035, a year after the death of his brother.
