Last Tsar's Murder Probe Raises Divisive Questions About Bolshevik Crimes - February 18, 2010 - The Kremlin has often tapped into the country's prerevolutionary past in a bid to revive a sense of national identity and pride in post-Soviet Russia. This has included steps such as canonizing the last imperial family in 2000 or reburying in St. Petersburg the tsar's mother, Empress Maria Fyodorovna, who died in exile in Denmark. Vladimir Putin, then president, attended the 2006 ceremony alongside descendants of the Romanov dynasty.
Maria Vladimirovna has said she is ready to step in as empress should Russians ever opt for the restoration of monarchy. So far, her overtures have remained unanswered.
Perhaps, but their claims are extremely weak, with Nicholas and his line being completely wiped out by the Bolsheviks.
