Russia is washed by twelve seas and three oceans: the Arctic, the Atlantic, the Pacific. Russia borders on many countries, such as Mongolia and China in the south-east, Finland and Norway in the north-west and so on.

The State symbol of Russia is a three-coloured flag. It has three horisontal stripes: white, blue and red. White colour represents “peace”, blue colour represents “loyalty” and red colour stands for “valour”.
The state emblem of Russia is a double-headed eagle, the most ancient symbol going back to the dynasty of the Riuricovichies. Russia's hymn was created by Alexandrov and Mikhalkov.
According to the Chronicle the history of Early Russia began in the year 862. That year Rurik became the first Russian prince having merged Novgorod and Kiev. Rurik's successor Prince Oleg did his best to strengthen and expand the nascent state. In 988 Prince Vladimir, the Red Sun, baptised Russia. For the first time Moscow was mentioned by the chroniclers in 1147. At that time Russian lands began to unite round Moscow, which led to the establishment of a strong centralised state.
