Page "History of Bulgaria" Paragraph 17

Sometime before 300 AD, Diocletian further divided Thracia into four smaller provinces.

Later in the 4th century, a group of Goths arrived in northern Bulgaria and settled in and around Nicopolis ad Istrum.

There the Gothic bishop Ulfilas translated the Bible from Greek to Gothic, creating the Gothic alphabet in the process.

This was the first book written in a Germanic language, and for this reason at least one historian refers to Ulfilas as " the father of Germanic literature ".

Due to the rural nature of the local population, Roman control of the region remained weak.

In the 5th century, Attila's Huns attacked the territories of today's Bulgaria and pillaged many Roman settlements.

By the end of the 6th century, Avars organized regular incursions into northern Bulgaria, which were a prelude to the en masse arrival of the Slavs.
