Dominions of Sweden in the context of "Uniformity policy"

Swedish Livonia (Swedish: Svenska Livland) was a dominion of the Swedish Empire from 1629 until 1721. The territory, which constituted the southern part of modern Estonia (including the island of Ösel ceded by Denmark after the Treaty of Brömsebro) and the northern part of modern Latvia (the Vidzeme region), 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 ("Livonian Principality"), which today corresponds to the Latgale region of Latvia.

Riga was the second largest city in the Swedish Empire at the time. Together with other Baltic Sea dominions, Livonia served to secure the Swedish dominium maris baltici. In contrast to Swedish Estonia, which had submitted to Swedish rule voluntarily in 1561 and where traditional local laws remained largely untouched, the uniformity policy was applied in Swedish Livonia under Karl XI of Sweden: serfdom was abolished, peasants were offered education as well as military, administrative or ecclesiastical careers, and nobles had to transfer domains to the king in the Great Reduction.

Swedish Pomerania (Swedish: Svenska Pommern; German: Schwedisch-Pommern) was a dominion of Sweden from 1630 to 1815 on what is now the Baltic coast of Germany and Poland. Following the Polish War and the Thirty Years' War, Sweden held extensive control over the lands on the southern Baltic coast, including Pomerania and parts of Livonia and Prussia (dominium maris baltici).

Sweden, which had been present in Pomerania with a garrison at Stralsund since 1628, gained effective control of the Duchy of Pomerania with the Treaty of Stettin in 1630. At the Peace of Westphalia in 1648 and the Treaty of Stettin in 1653, Sweden received Western Pomerania (German Vorpommern), with the islands of Rügen, Usedom, and Wolin, and a strip of Farther Pomerania (Hinterpommern). The peace treaties were negotiated while the Swedish queen Christina was a minor, and the Swedish Empire was governed by members of the high aristocracy. As a consequence, Pomerania was not annexed to Sweden like the French war gains, which would have meant abolition of serfdom, as the Pomeranian peasant and shepherd regulation of 1616 was practised there in its most severe form. Instead, it remained part of the Holy Roman Empire, making the Swedish rulers Reichsfürsten (imperial princes) and leaving the nobility in full charge of the rural areas and its inhabitants. While the Swedish Pomeranian nobles were subjected to reduction when the late 17th-century kings regained political power, the provisions of the peace of Westphalia continued to prevent the pursuit of the uniformity policy in Pomerania until the Holy Roman Empire was dissolved in 1806.

The Duchy of Estonia (Swedish: Hertigdömet Estland; Estonian: Eestimaa hertsogkond; German: Herzogtum Estland), also known as Swedish Estonia (Swedish: Svenska Estland), was a dominion of the Swedish Empire from 1561 until 1721 during the time that most or all of Estonia was under Swedish rule. The territory was eventually ceded to Russia in the Treaty of Nystad, following its capitulation during a plague outbreak in the Great Northern War.

The dominion arose during the Livonian War, when the northern parts of present-day Estonia — Reval (Tallinn) and the counties of Harjumaa, Western Virumaa, Raplamaa and Järvamaa — submitted to the Swedish king in 1561, and Läänemaa in 1581. It is also colloquially known as the "good old Swedish times" (Estonian: vana hea Rootsi aeg) by Estonians, but this expression was not used before the following Russian rule, in the beginning of which the situation of Estonian peasantry declined rapidly; to gain the support of the German Baltic nobility, Russia gave them more power over the peasantry.

With the Capitulation of Estonia and Livonia in 1710 the Swedish dominions Estonia and Livonia were integrated into the Russian Empire following their conquest during the Great Northern War. The Livonian nobility and the city of Riga capitulated on 4 July (O.S.) / 15 July 1710 (N.S.), Pernau (Pärnu) in August, and the Estonian nobility and the city of Reval (Tallinn) on 29 September (O.S.) / 10 October (N.S.). Russia left the local institutions in place and confirmed the traditional privileges of the German nobles and burghers as was established in Privilegium Sigismundi Augusti, especially with respect to the Protestant faith. The land reform of the so-called reduction which had been introduced by the Swedish king Charles XI, and transformed many serfs to subjects of the Crown, was reversed.

The Swedish Empire formally accepted the capitulations in the Treaty of Nystad in 1721. The transfer of the Baltic provinces marked the end of Sweden's and the beginning of Russia's time as a great power. The Baltic provinces retained their special status until the late 19th century.

Charles XI or Carl (Swedish: Karl XI; 4 December [O.S. 24 November] 1655 – 15 April [O.S. 5 April] 1697) was King of Sweden from 1660 until his death in 1697.

He was the only son of King Charles X Gustav and Hedwig Eleonora of Holstein-Gottorp. His father died when he was four years old, so Charles was educated by his governors until his coronation at the age of seventeen. Soon afterward, he was forced out on military expeditions to secure the recently acquired dominions from Danish troops in the Scanian War. Having successfully fought off the Danes, he returned to Stockholm and engaged in correcting the country's neglected political, financial, and economic situation. He managed to sustain peace during the remaining 20 years of his reign. Changes in finance, commerce, national maritime and land armaments, judicial procedure, church government, and education emerged during this period. Charles XI was succeeded by his only son Charles XII, who made use of the well-trained army in battles throughout Europe.

Swedish Ingria (Swedish: Svenska Ingermanland, ‘land of Ingrians’) was a dominion of the Swedish Empire from 1583 to 1595 and then again from 1617 to 1721 in what is now the territory of Russia. At the latter date, it was ceded to the Russian Empire in the Treaty of Nystad, at the end of the Great Northern War between the two empires.
