The current head of the Romanov family is Grand Duke George Mikhailovich of Russia.
He is the great-grandson of Grand Duke Michael Alexandrovich, who was the younger brother of Tsar Nicholas II. The Romanov family line continues through Michael's son, Grand Duke George Mikhailovich.
While the Romanov family was overthrown in the Russian Revolution of 1917, they have continued to exist as a family. The current head of the family is a descendant of the branch of the family that survived the revolution.
Grand Duke George Mikhailovich is a recognized figure in the Romanov family and is considered to be the head of the family by most Romanov descendants. He is not, however, a political figure and does not claim any right to the Russian throne.
He lives privately with his family in Switzerland, although he has made public appearances and spoken about the Romanov family's history.
