Boleslaw I the Brave (1025): Poland's First Crowned King
Boleslaw I the Brave was crowned Poland's first king in 1025, weeks before his death. His wars, the Congress of Gniezno in 1000 and his long road to a crown.

Contents
Bolesław I the Brave, known in Polish as Bolesław Chrobry, was crowned the first King of Poland in 1025, after more than thirty years as duke. His reign turned the young Piast state into a major Central European power, and the Congress of Gniezno in 1000 gave Poland its own church province. He died on 17 June 1025, only weeks after his coronation.
Background: Mieszko’s heir
Bolesław was born in 967, the son of Duke Mieszko I and the Bohemian princess Dobrawa. His father’s acceptance of Christianity in 966, described in the Baptism of Poland, brought the Polans into the Latin Christian world.
When Mieszko died in 992, Bolesław quickly removed his stepmother Oda and her sons and took control of the whole realm. He held Silesia and Lesser Poland, with Kraków, which his father had acquired around 990, and extended Polish power over Pomerania towards the Baltic.
Saint Adalbert and the Congress of Gniezno
In 997 Bolesław supported the mission of Adalbert, the former Bishop of Prague, to the pagan Prussians on the Baltic coast. Adalbert was killed there in April 997. Bolesław ransomed his body, according to tradition for its weight in gold, and buried it at Gniezno. Adalbert was canonised in 999, making Gniezno a place of pilgrimage.
In March 1000 the young emperor Otto III, a friend of Adalbert, travelled to Gniezno. Bolesław met him at Iława (Eulau) on the border, as the chronicler Thietmar of Merseburg records, and escorted him to Gniezno with great splendour. Thietmar adds that Otto approached the city barefoot as a pilgrim. At Gniezno an archbishopric was founded with suffragan bishops at Kraków, Wrocław and Kołobrzeg, giving Poland a church independent of German archbishops.
According to the 12th-century chronicler Gallus Anonymus, Otto placed his own imperial diadem on Bolesław’s head and gave him a copy of the Holy Lance. Historians debate how far this was meant as a royal elevation. It was part of Otto’s vision of a Christian empire of allied peoples, the same vision that helped Stephen I of Hungary obtain his crown at about the same time.
Wars with the empire and Kyiv
Otto III died in 1002, and his successor Henry II took a very different view. Bolesław occupied Lusatia and Milsko (Upper Lusatia) and in 1003–1004 briefly ruled Bohemia, including Prague. Three wars with Henry followed, ending with the Peace of Bautzen in 1018, which left Bolesław in possession of Lusatia and Milsko. The wars showed that Poland could hold its own against the strongest power in Latin Europe.
The same year Bolesław marched east to support his son-in-law Sviatopolk against Yaroslav the Wise. He defeated Yaroslav on the Bug river and entered Kyiv on 14 August 1018. On his way home he took the Cherven towns, a border region later recovered by Rus.
The coronation of 1025
Henry II died in July 1024, removing the main obstacle to a Polish crown. Bolesław had himself crowned king in 1025, most probably at Easter (18 April) in Gniezno Cathedral, apparently without the agreement of the new German king Conrad II. Contemporary sources are brief, and the exact date and the role of the papacy remain uncertain. The German chronicler Wipo complained that the Polish ruler had taken the royal title as an insult to Conrad, a sign of how political the crown remained.
Bolesław died on 17 June 1025 and was buried in Poznań Cathedral. His son Mieszko II was crowned later the same year, probably at Christmas.
Key people
- Bolesław I the Brave (967–1025), Duke of Poland from 992 and King in 1025.
- Otto III, Holy Roman Emperor, who came to Gniezno in 1000.

Legacy
Bolesław’s kingdom did not hold together. Under Mieszko II, attacks from neighbours and internal revolt led to a deep crisis in the 1030s, and Poland was not ruled by a crowned king again for decades. Yet the idea of a Polish kingdom with its own archbishopric survived. Later Polish tradition celebrated Bolesław as a warrior king, and the legend that he notched his sword, Szczerbiec, on the Golden Gate of Kyiv is still told, though the gate was built only after his campaign.

Why it matters
Bolesław’s coronation completed a process begun with his father’s baptism: Poland became a Christian kingdom with its own church and a recognised place among the states of Europe. The Congress of Gniezno and the crown of 1025 remain founding moments of Polish statehood.
Frequently asked questions
Who was the first King of Poland?
Bolesław I the Brave (Bolesław Chrobry) is regarded as the first crowned King of Poland. He was crowned in 1025, probably at Easter in Gniezno, and died a few weeks later on 17 June 1025.
What happened at the Congress of Gniezno?
In March 1000 Emperor Otto III made a pilgrimage to the tomb of Saint Adalbert in Gniezno. He and Bolesław agreed the creation of an archbishopric in Gniezno, and Otto honoured Bolesław as a friend and ally of the empire.
Why was Bolesław not crowned in 1000?
The Congress of Gniezno raised Bolesław's status, but a full royal coronation did not follow, probably because Otto III died in 1002 and his successor Henry II opposed a Polish crown. Bolesław was crowned only after Henry's death in 1024.
Did Bolesław the Brave capture Kyiv?
Yes. In 1018 Bolesław led an expedition to Kyiv to restore his son-in-law Sviatopolk to the throne, entering the city in August. On his return he took the Cherven towns on the border for Poland.
What does Chrobry mean?
Chrobry is an old Polish word meaning brave or valiant. The nickname became attached to him in later medieval tradition and reflects his reputation as a warrior king.
