As a given name, Diana has been regularly used since the Renaissance. It became more common in the English-speaking world following Walter Scott's novel Rob Roy (1817), which featured a character named Diana Vernon. It also appeared in George Meredith's novel Diana of the Crossways (1885). A notable bearer was the British royal Diana Spencer (1961-1997), the Princess of Wales.
In the Middle Ages this name was common in England due to the popularity of medieval tales about the Trojan War. It subsequently became rare, but was revived in the 20th century.
Other notable bearers of the name include the Russian emperor Boris Godunov (1552-1605), later the subject of a play of that name by Aleksandr Pushkin, as well as the Russian author Boris Pasternak (1890-1960), the Bulgarian king Boris III (1894-1943), and the Russian president Boris Yeltsin (1931-2007).
