An interdisciplinary collection of studies by Bulgarian and Estonian scholars focuses on cultural and religious processes and their current observation results. The topography covers the lands from Spain to Greece, the South-Balkan area more extensively and stretches from Ukraine to modern-day Russia. The national groups under observation (Estonians, Bulgarians, Serbians, Albanians, Roma, Turks and other groups) as well as religious trends and confessions and modern hobby groups, exert a multifaceted effect on transcultural phenomena today.
