Meaning and history
From a Bulgar Turkic name, also recorded as Bogoris, perhaps meaning “short,” “wolf,” or “snow leopard.” It was borne by Boris I of Bulgaria in the 9th century; after converting his realm to Christianity, he is thus regarded as a saint in the Orthodox Church. In Kievan Rus, the name was also borne by another saint, a son of Vladimir the Great who was murdered with his brother Gleb in the 11th century, and whose mother may have been Bulgarian. Other notable bearers include the Russian emperor Boris Godunov (1552-1605), later the subject of a play by Aleksandr Pushkin, the Russian author Boris Pasternak (1890-1960), the Bulgarian king Boris III (1894-1943), and the Russian president Boris Yeltsin (1931-2007).
Boris rose from #944 to #891 for boys between 1969 and 1970. That year also produced its highest recorded birth count, at 82.
