The first written record of a Romance language spoken in the Middle Ages in the Balkans was written by the Byzantine chronicler Theophanes Confessor in the 6th century about a military expedition against the Avars from 587, when a Vlach muleteer accompanying the Byzantine army noticed that the load was falling from one of the animals and shouted to a companion Torna, torna fratre (meaning “Return, return brother!”).
The oldest written text in Romanian is a letter from late June 1521, in which Neacșu of Câmpulung wrote to the mayor of Brașov about an imminent attack of the Turks. It was written using the Cyrillic alphabet, like most early Romanian writings. The earliest writing in Latin script was a late 16th century Transylvanian text which was written with the Hungarian alphabet conventions.
In the late 18th century, Transylvanian scholars noted the Latin origin of Romanian and adapted the Latin alphabet to the Romanian language, using some orthographic rules from Italian, recognized as Romanian’s closest relative. The Cyrillic alphabet remained in (gradually decreasing) use until 1860, when Romanian writing was first officially regulated.
In the Soviet Republic of Moldova, a special version of the Cyrillic alphabet derived from the Russian version was used, until 1989, when Romanian language, spoken there, has officialy returned to the Romanian Latin alphabet.
