Abstract
In this article of 1995, which had been translated into Russian already in 2013, the German Historian Stefan Troebst studied the question of the « breakthrough of the modern age » in Russia, usually attributed to tsar Peter I « the Great », suspecting that the new Era had in fact begun earlier, in the XVIIth century. After a theoretical reflexion about periodization in history, and its application to the history of Russia, he demonstrates that the « threshold year » takes place in 1667, examining this theory from different points of view: state and institutions, international relations, economical policy, religion, culture and fine arts. But this modernization has also caused violent revolts and oppositions during the reign of tsar Alexis Mikhailovitch.
