John III Sobieski was a major political and military leader. He served as the King of Poland and the Grand Duke of Lithuania. His reign lasted from 1674 until his death in 1696. 

Sobieski received a very thorough education in his youth. He graduated from the University of Kraków in 1646. After his studies, he spent two years traveling through Western Europe. He visited cities like Paris, London, and Antwerp. During these travels, he learned several languages. He became fluent in French, German, Italian, and Latin. 
His military career began during the Khmelnytsky Uprising in 1648. He and his brother, Marek, commanded their own cavalry units. These units included light "cossack" cavalry and heavy Polish hussars. 

Sobieski became an expert in Ottoman military tactics. He spent time as a hostage in the Crimean Tatar capital, Bakhchysarai. While there, he learned the Turkish and Tatar languages. This experience made him a very effective commander against the Ottoman Empire. He held many high offices, such as the Field Crown Hetman. Eventually, he reached the rank of Grand Hetman of the Crown. This was the highest military rank in the Commonwealth. 
Politics within the Commonwealth were often unstable. Different groups in the government often fought for power. In 1672, the pro-French group and the pro-court group formed rival confederations. This division led to the Treaty of Buchach, which was a difficult moment for the country. However, Sobieski used his military success to gain political strength. In 1673, he won a major victory at the Battle of Khotyn. 
As king, Sobieski worked to stabilize a country devastated by war. The national treasury was nearly empty. He focused on reforming the military to make it stronger. He organized the army into specific regiments. He also changed the equipment used by soldiers. For example, the infantry stopped using pikes and began using battle-axes.
His most famous achievement occurred at the Battle of Vienna in 1683.
