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 Second Northern War (1655–60), 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. The Dutch Republic waged an informal trade war against Sweden and seized the colony of New Sweden in 1655, but was not a recognized part of the Polish–Danish alliance.
The Time of Troubles, or Smuta, was a period of political crisis in the Tsardom of Russia which began in 1598 with the death of Feodor I, the last of the Rurik dynasty, and ended in 1613 with the accession of Michael I of the House of Romanov.
Prince Ivan Andreyevich Khovansky was a Russian boyar who led the Streltsy during the Moscow Uprising of 1682, alternatively known as the Khovanshchina. His life was dramatized by Modest Mussorgsky in the opera called after the name of the uprising. Khovansky's moniker, Tararui, derives from the old Russian word for "chatterbox".
The Ingrian War between the Swedish Empire and the Tsardom of Russia lasted between 1610 and 1617. It can be seen as part of Russia's Time of Troubles and is mainly remembered for the attempt to put a Swedish duke on the Russian throne. It ended with a large Swedish territorial gain in the Treaty of Stolbovo, which laid an important foundation to Sweden's Age of Greatness.
The Livonian War (1558–1583) was fought for control of Old Livonia. The Tsardom of Russia faced a varying coalition of the Dano-Norwegian Realm, the Kingdom of Sweden, and the Union of the Grand Duchy of Lithuania and the Kingdom of Poland.
The Russo-Swedish War of 1656-1658 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 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 Swedish Deluge.
The siege of Wesenberg was an abortive Swedish siege of the Russian-held town of Wesenberg in Estonia from January through March 1574, during the Livonian War. The siege is infamous for a brawl and subsequent combat between German and Scottish mercenaries within the besieging army, which claimed the lives of about 1,500 Scots. Wesenberg was seized in a renewed Swedish assault in 1581.
Novgorodian Land was one of the largest historical territorial–state formations in Russia, covering its northwest and north. Novgorod Land, centered in Veliky Novgorod, was in the cradle of Kievan Rus' under the rule of the Rurikovich dynasty and one of the most important princely thrones of the era. During the collapse of Kievan Rus' and in subsequent centuries, Novgorod Land developed as the Novgorod Republic: an autonomous state with republican forms of government under the suzerainty of the great princes of Vladimir-Suzdal. During the period of greatest development, it reached north to the White Sea, and in the east it spread beyond the Ural Mountains. It had extensive trade relations within the framework of the Hanseatic League and with the rest of Rus'. Muscovy conquered the Novgorod Republic in 1478, and annexed it in 1578, although Novgorod Land continued to exist as an administrative unit until 1708.
The Battle of Petschora took place on February 23, 1701 near the village of Pechory, Russia during the second year of the Great Northern War. The Swedish army of about 2,100 men assisted by approximately 2,000 peasants under the command of Jacob Spens defeated a Russian force of about 6,000 men.
