Slavic name

Given names originating from the Slavic languages are most common in Slavic countries.

In pre-Christian traditions, a child less than 7–10 years old would bear a "substitutional name", the purpose of which was to deflect attention from the child and thereby to protect it from the curiosity of evil powers. The practice was largely the effect of the high mortality rate for young children at the time. A child who survived to 7–10 years was considered worthy of care and was granted adult status and a new adult name during a ritual first haircut.

Traditional names remained dominant until the Slavic nations converted to Christianity. Finally, the Council of Trent (1545–63) decreed that every Catholic should have a Christian name instead of a native one.

After the ban on native non-Christian names imposed by the Council of Trent, the Polish nobility (especially Protestants) attempted to preserve traditional names, such as Zbigniew and . Ordinary people, however, tended to choose names solely from the Christian calendar, which contained only a handful of Slavic saints' names, in particular: Kazimierz (St. Casimir), Stanisław (St. Stanislaus), and Władysław (St. Ladislaus). Slavic names that referred to God (e.g. Bogdan, Bogumił) were also permitted.

Old Rus' names were based on common Slavic names such as Vladimir (Old East Slavic form Volodimer), Svyatopolk (holy regiment), Yaropolk, Voislav (glorious warrior), Borislav (glorious wrestler), Boris (fighter), Lyubomir (loves the world), Ratibor (war fighter), Vadim, , Izyaslav, Mstislav, Vsevolod. In the 11th century, after the growing influence of the Christian Church, the tendency to use the names of saints of the Greek Church has increased and most of old Rus' names were displaced by Dmytriy, Andrey, Nikolay, Terentiy, Sergey, Anton, Kirill, Georgiy, Konstantin, Alexandr, Foma, Akakiy, etc.
