This was the name of a 9th-century ruler of Bulgaria. It was also borne by an 11th-century grand prince of Kyiv, Vladimir the Great, who is venerated as a saint because of his efforts to Christianize his realm. Other notable bearers include the revolutionary and first leader of the Soviet state Vladimir Lenin (1870-1924), the Russian author Vladimir Nabokov (1899-1977), and the Russian president and prime minister Vladimir Putin (1952-).
In Japan the same sound and meaning was given to the kanji 零 (rei), probably after the contact with Western cultures. Zero has been used for some manga and anime characters.
