Thrace (theme)

The Theme of Thrace ( el, ) was a province (''thema'' or theme) of the Byzantine Empire located in the south-eastern Balkans, comprising varying parts of the eponymous geographic region during its history.

History

Traditionally, it has been held that the theme (at the time primarily a military command) was constituted in c. 680, as a response to the Bulgar threat... This is based on the mention of a certain ''patrikios'' Theodore, Count of the ''Opsikion'' and '' hypostrategos'' of Thrace, in 680/681. However, it is unclear whether this implies the existence of Thrace as a separate command, with Theodore holding a dual post, or whether Thrace was administratively united to the ''Opsikion''. In fact, separate ''strategoi'' of Thrace are not clearly attested in literary sources until 742, while seals of ''strategoi'' are also extant only from the eighth century on. Initially, Adrianople was probably the theme's capital.

Under Empress Irene of Athens, in the late eighth century, the theme was divided, with the western part being constituted as the separate theme of Macedonia. From then on, the theme's capital was at Arcadiopolis, with subordinate '' tourmarchai'' at Bizye and Sozopolis. Another, called ''tourmarches tes Thrakes'' ("of Thrace") is also attested, possibly the ''strategos deputy at Arcadiopolis. The Arab geographers Ibn Khordadbeh (wrote ca. 847) and Ibn al-Faqih (wrote ca. 903) mention the theme as extending "from the long wall he_he_Anastasian_Wall">Anastasian_Wall.html"_;"title="he_Anastasian_Wall">he_Anastasian_Wall_to_the_theme_of_Macedonia,_and_north_up_to_the_country_of_the_First_Bulgarian_Empire.html" "title="Anastasian_Wall.html" ;"title="Anastasian_Wall.html" ;"title="he Anastasian Wall">he Anastasian Wall">Anastasian_Wall.html" ;"title="he Anastasian Wall">he Anastasian Wall to the theme of Macedonia, and north up to the country of the First Bulgarian Empire">Bulgars, counting 10 fortified places and 5,000 troops.. Indeed, the boundaries of the theme fluctuated along with the northern frontier of Byzantium during the Byzantine–Bulgarian Wars. Initially, the theme must have comprised most of the ancient Diocese of Thrace, except for the country along the Danube overrun by the Bulgars (Lower Moesia), but after the conquests of Krum (r. 803–814), Omurtag (r. 814–831), and Symeon (r. 893–927) the border moved by stages south of the Balkan mountains to roughly the line of the present Bulgarian frontier with Greece and Turkey. Thus, at around the start of the tenth century, the theme comprised essentially the eastern half of modern Eastern Thrace, although it extended north along the coast to include Anchialos..

From the eleventh century, Thrace and Macedonia appear to have been usually combined, as attested by numerous ''strategoi'' and judges ('' kritai'') holding jurisdiction over both themes.. The name fell out of use as an administrative term in the Palaiologan period, but it is still encountered in some historians of the time as an antiquarian term.
