Economiya was, before the Revolution, the name for a large landed estate in the south of Russia and Ukraine that used hired labor and agricultural machinery.
Pyotr Nikolayevich Trubetskoy was the eldest son of Prince Nikolai Petrovich Trubetskoy, director of the Moscow branch of the Imperial Russian Musical Society. He and his sisters, Sofya and Maria, lost their mother early—Princess Lyubov Vasilyevna Trubetskaya, née Countess Orlova-Denisova.
On the economiya at Kazatskoye, which he inherited from his mother, there were numerous vineyards; their harvest served as raw material for magnificent wines made according to the prince’s recipes.
P. N. Trubetskoy died on October 4, 1911, killed by one of his own nephews, V. G. Kristi. The tragedy occurred in Novocherkassk, where the Trubetskoy and Kristi families had gathered for the ceremonial reburial of the remains of Don military figures, among them their ancestor Count V. V. Orlov-Denisov, into the crypt of the newly built Host Cathedral. After attending the mourning ceremony, Pyotr Nikolayevich went for a drive in an automobile with his nephew’s wife, the beautiful blonde Maria (Maritsa) Alexandrovna Kristi, née Mikhalkova (1883–1966). The pair arrived at the station and made themselves comfortable in the prince’s private railcar. The attendant was sent out for coffee and cognac. Before he returned, V. G. Kristi burst into the carriage; having searched for his wife for a long time, without saying a word he drew a Browning pistol and shot P. N. Trubetskoy. The lady tried to help the fallen man, but he died in her arms. “My mad husband has killed the prince!” she said to the attendant who ran into the compartment.
After the October Revolution, the princely economiya became the Lenin Wine State Farm; today it is JSC “Knyaz Trubetskoy.”
