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).
The Externsteine (Extern stones) is a distinctive sandstone rock formation located in the Teutoburg Forest, near the town of Horn-Bad Meinberg. The formation is a tor consisting of several tall, narrow columns of rock which rise abruptly from the surrounding wooded hills. Archaeological excavations have yielded some Upper Paleolithic stone tools dating to about 10,700 BC from 9,600 BC.
In a popular tradition going back to an idea proposed to Hermann Hamelmann in 1564, the Externsteine are identified as a sacred site of the pagan Saxons, and the location of the Irminsul (sacral pillar-like object in German paganism) idol reportedly destroyed by Charlemagne; there is however no archaeological evidence that would confirm the site's use during the relevant period.
The stones were used as the site of a hermitage in the Middle Ages, and by at least the high medieval period were the site of a Christian chapel. The Externsteine relief is a medieval depiction of the Descent from the Cross. It remains controversial whether the site was already used for Christian worship in the 8th to early 10th centuries.
The Externsteine gained prominence when Völkisch and nationalistic scholars took an interest in the late 19th and early 20th centuries. This interest peaked under the Nazi regime, when the Externsteine became a focus of nazi propaganda. Today, they remain a popular tourist destination and also continue to attract Neo-Pagans and Neo-Nazis.
