List of Polish monarchs

Poland has a long history of rulers, from early dukes to later kings. From the 10th century to 1795, many leaders guided the country. These rulers helped shape Poland and its place in the world.

Duke Mieszko I brought Christianity to Poland in 966. His son, Bolesław I the Brave, became the first king in 1025. Over time, different families ruled, including the Piast dynasty and the Jagiellonian dynasty. During the time of kings like Casimir IV Jagiellon and Sigismund I the Old, Poland grew in culture and cities, known as the Polish Renaissance.

Later, kings were chosen by nobles, and many came from other countries. Leaders like John III Sobieski fought in important battles. However, problems with rule and outside influences made times hard for Poland. By the late 1700s, Poland was divided among neighboring powers. Even after efforts to bring back an independent Poland during the Napoleonic Wars, the monarchy ended when Poland became a sovereign state in 1918.

Legendary

Main article: Poland in the Early Middle Ages

Many stories about early Polish rulers were written in the 13th century. We do not know if these rulers really existed.

House of Piast

Main article: History of Poland during the Piast dynasty

Mieszko I started ruling the Polans tribe and later united many lands to create Poland. He also chose Christianity, connecting Poland with western Europe. His family kept ruling, but the land often split among sons when a ruler died.

Main articles: Fragmentation of the realm and Testament of Bolesław III Wrymouth

After hard times, Bolesław III Wrymouth decided to split the land among his sons. One son would be the main ruler in Kraków, but this system didn’t last. Over time, the rules changed, and local leaders stopped obeying the main ruler.

In the 1300s, people wanted Poland to become one country again. Some leaders tried to make this happen, but they died before they could finish. Przemysł II tried to bring all the lands together but was killed in 1296, which slowed things down for many years.

Přemyslid House

The House of Přemyslid were kings of Bohemia and had close family ties with the Piast dynasty. In 1291, Wenceslaus II of Bohemia took control of Kraków during a time when Poland had internal problems. He claimed this was right because of distant family links to past leaders. Later, he married the daughter of Przemysł II, which helped him become a ruler in Poland.

House of Piast (restored)

Main article: Reunited Kingdom of Poland

Near the end of Wenceslaus II of Bohemia’s rule in Poland, some Polish dukes did not agree with him. One of them was Władysław I the Elbow-high, who had been sent away by Wenceslaus but had a strong right to the throne after Przemysł II passed. Another was Henry III, Duke of Głogów, who was also an heir of Przemysł.

When Wenceslaus III of Bohemia passed away, it caused problems in Bohemia and helped Władysław’s group in Poland. Later, Władysław united the main parts of Poland, Greater Poland and Lesser Poland, and became king in 1320. This ended a time when Poland was split into smaller pieces.

House of Anjou

Main article: Louis I and Jadwiga of the Anjou dynasty (1370–1399)

Casimir III the Great did not have a son to take over after him. His nephew, Louis I of Hungary, the king of Hungary, became the next ruler of Poland. This started a time when Poland and Hungary were ruled together. After Louis passed away, Poland and Hungary had separate rulers again. Louis's younger daughter, Jadwiga of Poland, became the queen of Poland. Meanwhile, Mary, Queen of Hungary became the queen of Hungary.

House of Jagiellon

Main article: History of Poland during the Jagiellonian dynasty

Jadwiga of Poland became queen when she was very young. She married Jogaila, the Grand Duke of Lithuania, who then became Władysław II Jagiełło. This marriage brought Poland and Lithuania closer together. After Jadwiga passed away, Władysław kept ruling Poland. He and the kings who came after him sometimes needed to promise special rights to the nobility to keep their support.

Polish–Lithuanian Commonwealth, 1569–1795

Main articles: Rzeczpospolita, History of the Polish–Lithuanian Commonwealth (1569–1648), History of the Polish–Lithuanian Commonwealth (1648–1764), and History of the Polish–Lithuanian Commonwealth (1764–1795)

In 1569, King Sigismund II Augustus joined Poland and Lithuania into one country called the Polish–Lithuanian Commonwealth. He did this because he had no children and wanted both countries to stay together after he passed away. He also made a big change: instead of the next ruler being from the same family, the nobles would choose the new king. This meant that any noble, not just the richest ones, could have a say.

The first king chosen this way was Henry III of France. He agreed to rules called the Henrician Articles, which let the nobles have a big role in how the country was run. Every king after him had to promise to follow certain policies in a document called a "pacta conventa." When a king died, the leader of the church in Poland would temporarily lead the country until a new king was chosen.

Duchy of Warsaw, 1807–1815

Main article: Duchy of Warsaw

After a difficult time, the land that was once the Polish–Lithuanian Commonwealth was divided by Russia, Prussia, and Austria. During the wars led by Napoleon, he created the Duchy of Warsaw using land from Prussia. Later, some land from Austria was added. The Duchy had its own leader and government but relied on France for support. When Napoleon’s time ended, the Duchy was divided again between Russia and Prussia.

Poland from 1815 to 1918

After the fall of the Duchy of Warsaw, Poland's lands were changed. Prussia took Greater Poland and made the Grand Duchy of Posen. Kraków became a free city, and the rest joined the Russian Empire as Congress Poland. In 1846, Austria took over Kraków, and in 1848, the Grand Duchy of Posen ended. In 1867, after the failed January Uprising, Congress Poland lost its independence.

During World War I, the Regency Kingdom was formed in German-occupied Congress Poland from 1917 to 1918. After Poland became independent again in 1918, it started a republican system with a president as the head of state.
