Casimir I the Restorer (Polish: Kazimierz I Odnowiciel; born 25 July 1016 – died 28 November 1058) was a very important ruler of Poland. He was a member of the Piast dynasty and served as the duke of Poland from 1040 until his death.
Casimir was the son of Mieszko II Lambert and Richeza of Lotharingia. He earned the nickname "the Restorer" because he successfully brought parts of the Kingdom of Poland back together after a difficult time. He managed to get back areas like Masovia, and also conquered Silesia and Pomerania. Even though he did a lot for Poland, he was never crowned King of Poland. This was mainly because of problems both inside and outside his country.

Casimir's Early Life
We don't know a lot about Casimir's very early years. He likely grew up at the royal court in Gniezno, Poland. To get a good education, he was sent to a Polish monastery around 1026.
Casimir's father, Mieszko II Lambert, became King of Poland in 1025. However, many powerful nobles in the country didn't want a strong king like Mieszko's father, Bolesław I the Brave. This caused a lot of arguments between the King and the nobles. Mieszko II's half-brother, Bezprym, and younger brother, Otto Bolesławowic, used this chance to turn against him. They even teamed up with the Holy Roman Emperor Conrad II. The Emperor's forces attacked Poland and took back some land.
During this troubled time, Casimir and his sisters went with their mother, Queen Richeza, to Germany for safety. It's believed that Queen Richeza took the Polish royal crown and other important items to Emperor Conrad II. This might have been to show that Bezprym accepted the Emperor's power, or perhaps the Queen took them to keep them safe. When his father died in 1034, Casimir was about 18 years old. He was in Germany, staying with his uncle, Archbishop Hermann II of Cologne.
A Time of Trouble in Poland
After Casimir's father died, Poland faced a lot of problems. The central region of Greater Poland (Wielkopolska) rebelled against the nobles and the Catholic Church. There was also a "pagan revival" where people went back to old beliefs. The region of Masovia broke away, and a local leader named Miecław created his own state. The same thing happened in Pomerania.
In 1037, young Casimir and his mother returned to Poland. They tried to take control of the throne, but local nobles rebelled. This, along with the "Pagan Reaction," forced Casimir and Richeza to flee to Saxony. Casimir tried again in 1038 to regain power with his mother's help, but it failed. He had to flee again, this time to the Kingdom of Hungary, where he was even put in prison by King Stephen I. Richeza stayed in Germany as a nun until she died.
While Poland was in chaos, Duke Bretislaus I of Bohemia took advantage of the situation. He invaded and damaged the country in 1039. Areas like Lesser Poland and Greater Poland were badly looted. Bretislaus captured Poznań and even stole important relics from Gniezno, including those of Saint Adalbert. On his way back, he conquered part of Silesia, including Wrocław. He also destroyed religious buildings and even looted the tomb of Mieszko I.
Casimir Becomes "The Restorer"
After escaping from Hungary, Casimir went to Germany. In 1039, his relative, Emperor Henry III, gave him military and financial help. The Emperor was worried about the growing power of the Bohemian ruler. Casimir received 1,000 soldiers and a lot of gold to help him get his power back in Poland.
Casimir also made an alliance with Yaroslav I the Wise, the Prince of Kievan Rus'. This alliance was made stronger by Casimir marrying Yaroslav's sister, Maria Dobroniega. With this support, Casimir returned to Poland and managed to take back most of his lands. In 1041, Bretislaus of Bohemia was defeated by Emperor Henry III. They signed a treaty in 1042 where Bretislaus gave up his claims to all Polish lands except for Silesia. Silesia was to become part of the Bohemian Kingdom. Casimir's success in making royal power stronger and ending the internal fights earned him the name "the Restorer."
The treaty gave Casimir a time of peace on his southern border. The capital of Poland was moved to Kraków, which was one of the few major Polish cities not badly damaged by the wars. It's likely that the Holy Roman Emperor was happy with the balance of power and didn't want Casimir to crown himself King of Poland.
In 1047, Casimir, with help from his brother-in-law from Kievan Rus', fought a war against Masovia and took control of that land. He probably also defeated Masovia's allies from Pomerania and added Gdańsk to Poland. This made his power strong in central Poland. Three years later, Casimir took Bohemian-controlled Silesia, even though the Emperor didn't want him to. This helped him get back most of the lands his father had ruled. In 1054, at a meeting in Quedlinburg, the Emperor decided that Silesia would stay with Poland. In return, Poland had to pay a yearly tribute of silver and gold.
After securing his borders, Casimir focused on making Poland stronger from the inside. To strengthen his rule, he brought back bishoprics in Kraków and Wrocław. He also built the new Wawel Cathedral. During Casimir's time, heraldry (the use of symbols like coats of arms) was introduced in Poland. Unlike earlier rulers, he gave more power to landed nobles instead of just his personal guard. One of his important changes was bringing a key part of feudalism to Poland. He gave land to his warriors, slowly turning them into medieval knights.
Family Life
Casimir married Maria Dobroniega (around 1012–1087), who was the daughter of Grand Duke Vladimir I of Kiev. Historians are not sure exactly when they got married, but it was likely between 1039 and 1043.
Casimir and Maria had five children:
- Bolesław II the Bold (born around 1043 – died 2 or 3 April 1081/82)
- Władysław I Herman (born around 1044 – died 4 June 1102)
- Mieszko (born 16 April 1045 – died 28 January 1065)
- Otto (born around 1046 – died 1048)
- Świętosława (born around 1048 – died 1 September 1126), who married Duke (later King) Vratislaus II of Bohemia around 1062.
