Yuri Nikolayevich Bogdanovich (Russian: Юрий Николаевич Богданович) (1849–1888) was a Russian revolutionary and Narodnik. His cadre name was Kobozev (Russian: Кобозев)
Bogdanovich was born on April 1, 1849 in Nikolskoye, in Toropets Uyezd, Pskov Governorate, into a noble family.
In 1869 Bogdanovich began work as county surveyor in the Velikiye Luki county of Pskov province. In 1871 he entered the St. Petersburg Medical-Surgical Academy but left in 1873 without being graduated, to concentrate on political activities. He began, with Vera Figner, to agitate among the peasants in the Volsky district of Saratov province.
In 1876 Bogdanovich joined the new Land and Liberty organization. On December 6, 1876, he participated in the "Kazan demonstration" in St. Petersburg.
In 1879, Land and Liberty split into two factions. One faction (the "villagers") supported continued agitation and propaganda in the countryside, the other faction (the "politicals") supported adopting more direct methods: terrorism. Bogdanovich supported the latter position and when Land and Liberty broke in two, he joined the resulting splinter organization, the People's Will (Narodnaya Volya).
In 1880 Bogdanovich became a member of the executive committee of the People's Will and was an active participant in organizing the assassination of Tsar Alexander II on March 1, 1881.
Under his nom de révolution of Kobozeva, Bogdanovich had opened a cheese shop on Malaya Sadovaya Street in St. Petersburg, from which a tunnel was dug to the middle of the street for laying mines. On the day before the assassination (February 28) the shop was raided, but the tunnel was not discovered. The tunnel was not used in the March 1 assassination and Bogdanovich escaped the ensuing dragnet.
