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-).
Due to the renown of the saint, this name has been widely used in the Christian world. It has been common in England since the 12th century, though it became a bit less popular after the Protestant Reformation. The name has been borne by five popes and two tsars of Russia.
In the United States it became more common for girls in the early 1980s, shortly after the debut of the television sitcom The Facts of Life (1979-1988), which featured a character named Blair Warner. The name left the American top 1000 rankings two decades later, but was resurrected by another television character, this time Blair Waldorf from the series Gossip Girl (2007-2012).
A famous bearer was the Cuban-French writer Anaïs Nin (1903-1977), known for her diaries.
The name has been used by kings of Scotland, Poland and Yugoslavia, emperors of Russia, and eight popes. Other notable bearers include English poet Alexander Pope (1688-1744), American statesman Alexander Hamilton (1755-1804), Scottish-Canadian explorer Alexander MacKenzie (1764-1820), Russian poet Alexander Pushkin (1799-1837), and Alexander Graham Bell (1847-1922), the Scottish-Canadian-American inventor of the telephone.
