siege of Constantinople in 717–718. The
Nominalia of the Bulgarian khans states that Tervel belonged to the
Dulo clan and reigned for 21 years. The testimony of the source and some later traditions allow identifying Tervel as the son of
Asparukh.

, Justinian again sought the aid of Tervel, but obtained only lukewarm support manifested in an army of 3,000. Outmaneuvered by the rebel emperor
Philippicus, Justinian was captured and executed, while his Bulgarian allies were allowed to retire to their country. Tervel took advantage of the disorders in Byzantium and raided Thrace in 712, plundering as far as the vicinity of Constantinople.
Given the chronological information of the ''Imennik'', Tervel would have died in 715. However, the Byzantine Chronicler
Theophanes the Confessor ascribes Tervel a role in an attempt to restore the deposed Emperor
Anastasius II in 718 or 719. If Tervel had survived this long, he would have been the Bulgarian ruler who concluded a
new treaty (confirming the annual tribute paid by the Byzantines to Bulgaria, the territorial concessions in Thrace, regulating commercial relations and the treating of political refugees) with Emperor
Theodosius III in 716. However, elsewhere Theophanes records the name of the Bulgarian ruler who concluded the treaty of 716 as ''Kormesios'', i.e., Tervel's eventual successor
Kormesiy. It is probable that the chronicler ascribed the events of 718 or 719 to Tervel simply because this was the last name of a Bulgar ruler that he was familiar with, and that his sources had been silent about the name, as in his account of the siege of Constantinople. According to another theory Kermesios was authorized by Tervel to sign the treaty.
Most researches agree that it was during the time of Tervel when the famous rock relief the
Madara Rider was created as a memorial to the victories over the Byzantines, to honour his father Asparukh and as an expression of the glory of the Bulgarian state.

and besieged Constantinople with a large army and navy.
Leo III made a plea to Tervel for help, relying on the treaty of 716, and Tervel agreed. The first clash between the Bulgars and the Arabs ended with a Bulgar victory. During the very first stages of the siege the Bulgars appeared in the Muslim rear and large part of their army was destroyed and the rest were trapped. The Arabs built two trenches around their camp facing the Bulgarian army and the
walls of the city. They persisted with the siege despite the severe winter with 100 days of snowfall. In the spring, the

. Finally, in early summer the Arabs engaged the Bulgars in battle but suffered a crushing defeat. According to
Theophanes the Confessor, the Bulgars slaughtered some 22,000 Arabs in the battle. Shortly after, the Arabs raised the siege.
In 719, Tervel again interfered in the internal affairs of the Byzantine Empire when the deposed emperor
Anastasios II asked for his assistance to regain the throne. Tervel provided him with troops and 360,000 gold coins. Anastasios marched to Constantinople, but its population refused to cooperate. In the meantime Leo III sent a letter to Tervel in which he urged him to respect the treaty and to prefer peace to war. Because Anastasios was abandoned by his supporters, the Bulgarian ruler agreed to Leo III's pleas and broke relations with the usurper. He also sent Leo III many of the conspirators who had sought refuge in

The cult of St. Trivelius
In his
''Slav-Bulgarian History'' (1762),
Paisius of Hilendar interprets Tervel's character based on a copperplate engraving from
Hristofor Žefarović's ''
Stemmatografia'' (1741), which depicts St. David, king of Bulgaria and St. Theoctistus. In the image of Saint Theoctistus, which is the monastic name of the Serbian king
Stefan Dragutin
Stefan Dragutin ( sr-Cyrl, Стефан Драгутин, ; died 12 March 1316), was List of Serbian monarchs, King of Serbia from 1276 to 1282. From 1282, he ruled a Realm of Stefan Dragutin, separate kingdom which included northern Serbia, and ...
, Paisius recognized King Trivelius or Tervel.
Among other things, Paisius wrote about this Bulgarian ruler:

"''Zographic History''" (1760's) will even try to locate the monastery of St. Teoctist close to
Ohrid
Ohrid ( ) is a city in North Macedonia and is the seat of the Ohrid Municipality. It is the largest city on Lake Ohrid and the eighth-largest city in the country, with the municipality recording a population of over 42,000 inhabitants as of ...
, and the hieromonk
Spiridon Gabrovski in his "''Istoriya''" from 1792, points out that in Ohrid "in his monastery until today lie his relics". It is striking that the "''Zographic History''" and "''Slav-Bulgarian History''", which appeared almost simultaneously, are the first texts that mention King Trivelius, in general, in Balkan literature, which is not the case in Western literature, where he has been strongly present since the 16th century. In the western literature, which was apparently also a source for the mentioned
Athonian monks, there is also the episode about his monasticism, but in no source before the "''History of Paisius''" his monastic name is mentioned, which is obviously an original construction of Paisius in order to connect Trivelius with the figure of Theoctistus from the "''Stematographia''".
In addition, it is important to emphasize that Paisius was aware of the fact that the Serbian king Dragutin received monasticism with the name Theoctistus, so it is even more surprising that he connected the figure of the monk Theoctistus from the "''Stematographia''" with the Bulgarian ruler Trivelius.
Another copperplate engraving by Žefarović from the same year 1741, which was made just a few months before the publication of the "''
Stemmatografia''", is particularly useful for identifying the image of St. Theoctistus from the Stematography. This copperplate depicting Saint Sava with Serbian saints from the house of Nemanjic was conceived as a kind of propaganda political memorandum, and was sent as a congratulatory message to Empress
Maria Theresa
Maria Theresa (Maria Theresia Walburga Amalia Christina; 13 May 1717 – 29 November 1780) was the ruler of the Habsburg monarchy from 1740 until her death in 1780, and the only woman to hold the position suo jure, in her own right. She was the ...
on the occasion of her ascension to the throne. Seventeen holy figures are represented on the copperplate. In the second row of saints, Saint Theoctistus is represented, with clearly written signatures. All the characters presented, without exception, find their analogy in the saints from the house of Nemanja, so such an analogy should be sought for the character of Saint Theoctist.
The interpretations by Paisius, by analogy and without critical analysis, will be taken up in the later Bulgarian literature and will create a fictitious and until then non-existent saint cult, which will be reflected in the paintings of the 18th and 19th centuries.

Tervel Peak on Livingston Island in the South Shetland Islands, Antarctica is named after Tervel of Bulgaria.
