Перевести)The Russian flag is sometimes called the IMPERIAL FLAG. It consists of three equal stripes of white, blue and red. The first flag of this design appeared more than 300 year ago. Peter the Great adapted the flag from the National flag of the Netherlands. Later a black two – headed eagle on a golden background was added to the flag of Russia. The flag existed until the revolution in 1917. In the nineties, with the democratic changes, the tree – colour flag was restored again. On 21 August 1991, the flag was officially adopted by the Russian President and the Russian Parliament.

In Russia the colours of the current flag symbolise:
white-frankness and generosity;
blue-honesty and wisdom;
red-courage and love.
