He was the Head of the Imperial Family of Russia, a position which he claimed from 1938 until his death in 1992.
On 13 August 1948 he married Princess Leonida Georgievna Bagration of Mukhrani and they had a daughter Grand Duchess Maria Vladimirovna of Russia.
Grand Duke Vladimir of Russia died of an apparent heart attack while addressing a gathering of Spanish-speaking bankers and investors in Miami in the United States on 21 April 1992.
His body was returned to Russia and he was buried with full pomp and splendour in the Peter and Paul Fortress in St Petersburg, the first Romanov to be honoured in this way since before the revolution. The press noted that the funeral "was regarded by civic and Russian authorities as an obligation to the Romanov family rather than a step toward restoration of the monarchy."
