Prince Pyotr Vladimirovich Dolgorukov (Russian: Пётр Владимирович Долгоруков) (1816–1868) was a Russian historian and journalist known for his genealogical research and as a critic of the Imperial Russian government. His father was the general Vladimir Petrovich Dolgorukov.
Dolgorukov was known for his anti-government publications. He moved to Paris in 1859 and refused to return to Russia.
As a result, he was deprived by the authorities of all titles and property, and declared a permanent exile. After Dolgorukov's death, his archives were acquired by the Russian government.
Some of Dolgorukov’s chief works include:
