During the 17th century, despite having scarcely more than 1 million inhabitants, Sweden emerged to have greater foreign influence, after winning wars against Denmark–Norway, the Holy Roman Empire, Russia, and the Polish–Lithuanian Commonwealth.

The Polish–Swedish War (1617–1618) was a phase of the longer Polish–Swedish War of 1600–1629. It continued the war of 1600–1611 and was an attempt by Sweden to take Polish pressure off Russia. The Polish–Lithuanian Commonwealth was then also fighting Tartars and the Ottoman Empire. Russia and Sweden were at that stage allied, prior to the Ingrian War, part of Russia's Time of Troubles. The 1617–1618 war's cause was a dispute over Livonia and Estonia, and a dispute between Sigismund III Vasa and Gustavus Adolphus over the Swedish throne.
The Swedish Empire or the Age of Greatness was the period in Swedish history spanning much of the 17th and early 18th centuries during which Sweden became a European great power that exercised territorial control over much of the Baltic region. During this period it also held territories on the North Sea and some overseas colonies, including New Sweden. The beginning of the period is usually taken as the reign of Gustavus Adolphus, who ascended the throne in 1611, and its end as the loss of territories in 1721 following the Great Northern War.

The Battle of Gniew or the Battle of Mewe was fought during the Polish–Swedish War (1626–1629), between Sweden and the Polish–Lithuanian Commonwealth from 22 September with initial skirmishes, to the main battle of October 1 1626. Both the Swedish and Polish army were commanded by their kings – Gustavus Adolphus of Sweden and Sigismund III Vasa. The battle ended indecisively. However, Polish and Swedish armies had different objectives. Sigismund Vasa wanted to protect Gdańsk from besieging. Gustav had to protect Gniew, which was important for the prestige of his army. The battle ended in a Swedish victory.
Gustavus Adolphus, also known in English as Gustav II Adolf or Gustav II Adolph, was King of Sweden from 1611 to 1632, and is credited with the rise of Sweden as a great European power.
