The Theme of Cherson ( el, , ''thema Chersōnos''), originally and formally called the Klimata (Greek: ) and Korsun', was a
Byzantine theme (a military-civilian province) located in the southern
Crimea, headquartered at
Cherson.
The theme was officially established in the early 830s and was an important centre of
Black Sea commerce. Despite the destruction of the city of Cherson in the 980s, the theme recovered and prospered, enduring until it became a part of the
Empire of Trebizond

dissolution of the Byzantine Empire in 1204.
History
The region had been under
Roman and later Byzantine imperial control until the early 8th century, but passed under
Khazar control thereafter. Byzantine authority was re-established by Emperor
Theophilos (r. 829–842), who displayed interest in the northern littoral of the Black Sea and especially his relations with the Khazars. Traditional scholarship dates the establishment of Cherson as the seat of a theme in ca. 833/4,
[.][.] but more recent researchers have linked it with the Byzantine mission to construct the new Khazar capital at
Sarkel in 839, and identify
Petronas Kamateros, the architect of Sarkel, as the theme's first governor (''

'') in 840/1.
The new province was at first called ''ta Klimata'', "the regions/districts", but due to the prominence of the capital Cherson, by ca. 860 it was known even in official documents as the "Theme of Cherson".
The province played an important role in Byzantine relations with the Khazars and later, after the Khazar Khaganate's collapse, with the
Pechenegs and the
Rus'. It was a center for

rather than military activity, since the military establishment in the theme seems to have been small and to have chiefly consisted of a locally raised militia. Its weakness is underlined by the stipulation, in the Byzantine treaties with the Rus' of

The city recovered quickly: the city's fortifications were restored and extended to the harbour in the early 11th century. At the same time, possibly after the defeat of
Georgius Tzul in 1016, the theme was extended over the eastern Crimea as well, as evidenced by the styling of a certain Leo Aliates as "''strategos'' of Cherson and
Sougdaia" in 1059. The region however was lost again in the late 11th century to the
Cumans.
Almost nothing is known of Cherson in the 12th century, pointing to a rather tranquil period. Cherson and its province remained under Byzantine control until the dissolution of the Empire by the

Administration

The Theme of Cherson appears to have been organized in typical fashion, with the full array of thematic officials, of whom a ''
tourmarches'' of
Gothia is known at the turn of the 11th century, as well as the ubiquitous fiscal and customs officials known as ''
kommerkiarioi''.
The cities of the theme, however, appear to have retained considerable autonomy in their own government, as exemplified by Cherson itself, which was administered by the local magnates (''

Cherson also retained the right to issue its own

Its autonomy is also evidenced by the fact that the imperial government paid annual subsidies (''pakta'') to the city leaders in the fashion of allied rulers, and in the advice of Emperor

In the late 11th century, the theme was governed by a ''
