Hey kiddo! Did you know that a long time ago, back in the 1700s, there was a country called the Polish-Lithuanian Commonwealth? This was a big country made up of both Poland and Lithuania. People who lived there called themselves Poles and Lithuanians, and they all spoke a language called Polish.
Now, back then, there was a king named Stanisław August Poniatowski who ruled over this big country. But even though he was king, there were also other people who had a lot of power and influence in the country, such as the nobles, who owned a lot of land.
Things were not always peaceful in the Polish-Lithuanian Commonwealth. Some of the people who lived there wanted more say in how the country was run. They believed that the king and the nobles had too much power and that they needed to share it more fairly.
One of the people who believed this was a man named Tadeusz Kościuszko. He was a soldier and a hero to many people in the country. He helped lead a rebellion against the government in 1794. This was called the Kościuszko Uprising.
Unfortunately, the rebellion was not successful, and the Polish-Lithuanian Commonwealth was eventually divided up and taken over by its neighboring countries, such as Russia, Austria, and Prussia. This happened in 1795, and it was the end of the Polish-Lithuanian Commonwealth.
Overall, the history of the Polish-Lithuanian Commonwealth during this time period was one of political unrest and division. But it is an important part of the history of Poland and Lithuania, and it shows how people can come together to fight for what they believe in, even if they don't always succeed.
