Russian Empire

Romanov Empire (micronation)
Bakov declared the new Russian Empire to be the successor to the historical Russian Empire that ceased to exist in 1917. The Imperial Throne also claimed the right to maritime territories that were either claimed by the Russian Empire or discovered by the Imperial Russian Navy but never absorbed into the Soviet Union. The 17 claimed territories include the entire continent of Antarctica and land under the jurisdiction of Japan, the United Kingdom, the United States, and other nations.
