The review of the XVIII International Scientific Conference "State and Law: evolution, current state, development prospects (to the 300th anniversary of the Russian Empire)" was held on April 29-30, 2021 at the St. Petersburg University of the Ministry of Internal Affairs. The Russian Empire existed on the political map of the world from October 22 (November 2), 1721 until the February Revolution and the overthrow of the Monarchy on March 3, 1917. The Russian Empire was the third largest state that ever existed (after the British and Mongolian Empires): It extended to the Arctic Ocean in the north and the Black Sea in the south, to the Baltic Sea in the west and the Pacific Ocean in the east. The Russian Empire was one of the great powers along with Great Britain, France, Prussia (Germany) and Austria-Hungary, and since the second half of the XIX century – also Italy and the United States. The capital of the Russian Empire was St. Petersburg (1721 - 1728), Moscow (1728 - 1732), then again St. Petersburg (1732 - 1917), renamed Petrograd in 1914. Therefore, it is natural that a conference dedicated to the 300th anniversary of the formation of the Russian Empire was held in St. Petersburg, the former imperial capital. The conference was devoted to problems concerning various aspects of the organization and functioning of the state and law, a retrospective analysis of the activities of state bodies in the Russian Empire. The discussion focused on various issues: the character of the Russian Empire as a socio-legal phenomenon and the subject of the legitimate use of state coercion, the development of political and legal thought, the regulatory and legal foundations of the organization and functioning of the Russian state in the XVIII century – at the beginning of the XX century, the characteristics of state bodies as an element of the mechanism of the imperial state in Russia, the organizational and legal bases of the activities of bodies that manage the internal affairs of the Russian Empire, as well as the image of state authorities and officials-representatives of state power.
