History of Estonia between 1561 - 1721
The Duchy of Estonia, also known as Swedish Estonia, was a dominion of the Swedish Empire from 1561 until 1721, when it was ceded to Russia in the Treaty of Nystad, following its capitulation, during the plague, 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" 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 support of German nobility, Russia gave them more power over peasantry).
Křivoklát Castle was founded in the 12th century, belonging to the kings of Bohemia. During the reign of Přemysl Otakar II a large, monumental royal castle was built, later rebuilt by king Václav IV and later enlarged by king Vladislav of Jagellon.
The castle was damaged by fire several times. It was turned into a harsh prison and the building slowly deteriorated. During the 19th century, the family of Fürstenberg became the owners of the castle and had it reconstructed after a fire in 1826.
Today the castle serves as a museum, tourist destination and place for theatrical exhibitions. Collections of hunting weapons, Gothic paintings and books are stored there.
