Nomenclature

The First Bulgarian Empire became known simply as Bulgaria since its recognition by the Byzantine Empire in 681. Some historians use the terms Danube Bulgaria, First Bulgarian State or First Bulgarian Tsardom (Empire). Between 681 and 864 the country was also known as the Bulgarian Khanate, Danube Bulgarian Khanate or Danube Bulgar Khanate in order to differentiate it from Volga Bulgaria

 which emerged from another Bulgar group. During its early existence the country is also called Bulgar state or Bulgar qaghnate. Between 864 and 917/927 the country was known as Principality of Bulgaria or Knyazhestvo Bulgaria.

In English language sources the country is often known as the Bulgarian Empire.

Created as a union between Bulgars and Slavs, for mutual protection against the Byzantine Empire to the south and the Avars to the north-west, the First Bulgarian Empire was ruled according to the Bulgar tradition with the head of state being the Khan. The Slavs kept significant autonomy and eventually their language and traditions shaped the Bulgarian culture and people with Bulgaria becoming a Slavic country

Establishment of Bulgaria

There are two different dates for the year of establishment of present-day Bulgaria, based upon two different interpretations of history. According to the first, after their defeat by the Khazars, another Bulgar tribe, led by Khan Asparuh

Another theory is that although Great Bulgaria suffered major territorial losses from the Khazars

Establishing a firm foothold in the Balkans

After the decisive victory at Ongala in 680 the armies of the Bulgars and Slavs advanced to the South of the Balkan mountains, defeating again the Byzantines who were then forced to sign a humiliating peace treaty which acknowledged the establishment of a new state on the borders of the Empire. They were also to pay an annual tribute to Bulgaria. In the same time the war with the Khazars

Ceramics

One of the most famous features of the Pliska-Preslav culture was the decoration of palaces and churches with lacquered ceramic plates, which may indicate a Near Eastern (Arabic) influence. The ceramic plates were painted mostly with geometric or vegetative elements, while a few feature depictions of saints. Among the most notable of the latter is the well-preserved 20-tile Icon of St Theodore, found in the ruins of the Saint Panteleimon Monastery in the outskirts of Preslav. The tiles were either flat or tubular, and were arranged to form friezes of repeating motifs. Due to the destruction of Pliska and Preslav only fragments and details of the ceramic decoration have survived. Most finds of tiles, as well as archaeological evidence of the workshops producing them, come from Preslav and the surrounding region (chiefly the village of Patleina).
