Connection to assassination plots
In 1885, Baron Arthur von Mohrenheim, head of the Russian Okhrana (secret police) in Paris, reported to his replacement, Pyotr Rachkovsky, that the widowed Princess Yurievskaya had been using her money to finance a group of Russian nihilists who were attempting to kill Emperor Alexander III and his family. Rachkovsky dismissed the rumor as absurd.
However, the rumor gained traction when a young Georgian nationalist, Prince Viktor Nakachidze, was convicted in late 1885 for participating in a nihilist bomb plot to kill the Emperor. Through his Mingrelian relatives, Prince Victor Nakashidze had connections to Princess Agrippina Japaridze, the wife of Duke Constantine Petrovich, and to the Dadiani family Archived 2012-07-23 at the Wayback Machine -- Salome, Niko and Andria Dadiani—the Georgian royal family then living in exile at Nice.
For his role in the bomb plot, Prince Victor Nakachidze was sentenced to death and sent to Siberia. However, with the aid of his wife, Mlle. Roedel, he managed to escape, travelling across the Pacific to the United States. The couple eventually resurfaced in London.
In 1890, Rachkovsky managed to entrap and convict Prince Victor Nakachidze and 26 of his associates as they prepared to set off bombs at the 1890 "Exposition Universelle" (World Fair) in Paris. Once again, after serving only a few years in prison, Prince Nakachidze escaped.
In 1896, Prince Viktor Nakachidze resurfaced in Italy, where he gave up making bombs and masterminded an attempt to kill Emperor Nicholas II with poison. Observing that the Emperor often wore dress gloves, Nakachidze's circle studied the history of the Borgias at a local library in Milan, learned how to make powerful poisons, and recruited an agent in the palace at St. Petersburg to replace the Emperor's dress gloves with poison-coated gloves.
This murder attempt, reported in September 1896 by the international press, was very nearly successful. Doctors specializing in toxicology were summoned quickly to the palace and Emperor Nicholas made no public appearances for more than a week.
Shortly after the marriage of Prince George Yurievsky to Countess Alexandra von Zarnekau at Nice in 1901, a connection between Prince Viktor Nakachidze and the Yurievsky circle in Nice became clear.
Nakachidze was arrested in Nice by French police "who affirm that they have full proof that the Prince was engaged in a plot to assassinate the Russian Emperor should he visit the Riviera." The French jailed Nakachidze for two weeks, then released him. While attempting to rejoin his group in Milan, Prince Nakachidze was arrested again by Italian police at Rome.
On this occasion he gave a brief interview to the press and claimed that he was not an anarchist, but a patriot and a Georgian nationalist. He said he had returned to France, despite a long-standing banishment, because he was homeless and in great need of financial help.
Strangely, Prince Viktor Nakachidze claimed that he represented "a legitimate pretender to the Russian crown." The only person living in Nice, France, who could reasonably have made a legitimate claim to the Russian crown was Prince George Yurievsky.
Emperor Nicholas II therefore had reason to look with suspicion on the marriage arranged in 1900 between the eldest daughter of Duke Constantine Petrovich and Prince George Yurievsky. Duke Constantine Petrovich appeared to be forging an alliance with the Yurievsky circle in Nice — a group that had a potentially valid claim to the Russian crown, and a wealthy group that now appeared to be offering financial aid to Prince Viktor Nakachidze, a well-known Georgian assassin and bomb-maker.
