What it is

The first alphabet created to write Slavic, devised by Constantine-Cyril before the mission to Great Moravia. It made it possible to translate the liturgy and the gospels into a Slavic language.

It is attributed to Constantine-Cyril (born in Thessaloniki), who worked in Constantinople around 862-863; the place of creation is the Byzantine capital, not a present-day Balkan territory, but the milieu and disciples are Balkan. The order relative to Cyrillic is now accepted (Glagolitic is the older).

What it led to

  • Church literature in Old Church Slavonic and the spread of Christianity among the Slavs
  • Glagolitic use in Croatia into the 20th century, with printed books from 1483
  • inspiration for the Cyrillic alphabet
