Gustavus Adolphus was born in Stockholm on December 9, 1594. He was the eldest son of King Charles IX and Queen Christina of Holstein-Gottorp. His education was managed by the intellectual Johan Skytte. He studied history, politics, law, and several languages. These included Swedish, German, Latin, French, Dutch, and Italian. He became king in 1611 at the age of sixteen. Because he was so young, the Swedish Riksdag ruled he could not be formally crowned until age twenty-four. Axel Oxenstierna, the Lord High Chancellor, served as regent during this time.
Upon his ascension, the young king inherited three active wars. He faced conflicts with Denmark–Norway, Russia, and Poland-Lithuania. The war with Denmark–Norway was considered the most serious at first. It threatened the very existence of the Swedish realm. The conflict with Russia ended in 1617 with the Treaty of Stolbovo. This treaty excluded Russia from the Baltic Sea. The war against Poland ended in 1629 with the Truce of Altmark. This truce transferred the province of Livonia to Sweden. These victories allowed Sweden to focus its resources on the Thirty Years' War.
In June 1630, Gustavus Adolphus intervened in the Thirty Years' War. He launched an invasion of northern Germany and Pomerania. He initially had only 4,000 troops but soon received reinforcements and French money. His most famous victory occurred at the Battle of Breitenfeld in 1631.

His military successes also had lasting impacts on his followers. He taught commanders like Lennart Torstensson, who later expanded Swedish power. Even after his death, the Swedish state remained strong under the leadership of Axel Oxenstierna.
