Swedish Livonia was a dominion of the Swedish Empire from 1629 until 1721. The territory, which constituted the southern part of modern Estonia and the northern part of modern Latvia, represented the conquest of the major part of the Polish-Lithuanian Duchy of Livonia during the 1600–1629 Polish-Swedish War. Parts of Livonia and the city of Riga were under Swedish control as early as 1621 and the situation was formalized in the Truce of Altmark 1629, but the whole territory was not ceded formally until the Treaty of Oliva in 1660. The minority part of the Wenden Voivodeship retained by the Polish–Lithuanian Commonwealth was renamed the Inflanty Voivodeship, which today corresponds to the Latgale region of Latvia.
Field Marshal and Count Jacob Pontusson De la Gardie was a statesman and a soldier of the Swedish Empire, and a Marshal from 1620 onward.
The Deluge was a series of mid-17th-century military campaigns in the Polish–Lithuanian Commonwealth. In a wider sense, it applies to the period between the Khmelnytsky Uprising of 1648 and the Truce of Andrusovo in 1667, comprising the Polish theatres of the Russo-Polish and Second Northern Wars. In a stricter sense, the term refers to the Swedish invasion and occupation of the Commonwealth as a theatre of the Second Northern War (1655–1660) only; in Poland and Lithuania this period is called the Swedish Deluge, or less commonly the Russo–Swedish Deluge due to the simultaneous Russo-Polish War. The term "deluge" was popularized by Henryk Sienkiewicz in his novel The Deluge (1886).
The Northern War of 1655–1660, also known as the Second Northern War, First Northern War or Little Northern War, was fought between Sweden and its adversaries the Polish–Lithuanian Commonwealth (1655–60), the Tsardom of Russia (1656–58), Brandenburg-Prussia (1657–60), the Habsburg monarchy (1657–60) and Denmark–Norway.

Prince Ivan Andreyevich Khovansky was a Russian boyar who led the Streltsy during the Moscow Uprising of 1682, alternatively known as the Khovanshchina.

The Ingrian War was a conflict fought between the Swedish Empire and the Tsardom of Russia which lasted between 1610 and 1617.

The Russo-Swedish War of 1656–1658, known as the War of Rupture, was fought by Russia and Sweden as a theater of the Second Northern War. It took place during a pause in the contemporary Russo-Polish War (1654–1667) as a consequence of the Truce of Vilna. Despite initial successes, Tsar Alexis of Russia failed to secure his principal objective—to revise the Treaty of Stolbovo, which had stripped Russia of the Baltic coast at the close of the Ingrian War. The war ended in a Swedish victory.
The Russo-Polish War of 1654–1667, also called the Thirteen Years' War, Muscovite War of 1654–1667 and the First Northern War, was a major conflict between the Tsardom of Russia and the Polish–Lithuanian Commonwealth. Between 1655 and 1660, the Swedish invasion was also fought in the Polish–Lithuanian Commonwealth and so the period became known in Poland as "The Deluge" or Russian Deluge.
