tes'' and ''strategoi'' of Strymon are known from the second quarter of the 9th century.
[.] In addition, the bishop of Serres was elevated to an archbishop at about the same time, a possible indication of the establishment of a thematic capital there.
Several authors like the French Byzantinist
Paul Lemerle support its creation in the late 840s, during
Theoktistos's anti-Slavic campaigns, but historian
Warren Treadgold considers it to have become a full theme in c. 896, to counter the threat of the
Bulgarian tsar
Symeon I (r. 893–927).

In the late 10th century, the theme was divided in two parts: Strymon proper, also known as Chryseuba or Chrysaba (Χρυσεύβα/Χρυσάβα, according to the Greek scholar
Nikolaos Oikonomides a
Hellenized form of "Krushevo", modern
Achladochori), and the theme of New Strymon (Νέος Στρυμών). The latter is known only through the ''
Escorial Taktikon'' of c. 975. Oikonomides identifies it either with the portion of the old theme east of the Nestos, which was later raised to a separate theme as
Boleron (Greek: Βολερόν), or with a northern portion along the upper Strymon, possibly acquired after Emperor
John I Tzimiskes's (r. 969–976)
conquest of Bulgaria in 971.
Towards the end of the 10th century, the theme of Strymon appears to have been united with that of Thessalonica and perhaps also
Drougoubiteia, while in the 11th century it appears united with Boleron.
The theme continued in existence until the dissolution of the Byzantine Empire by the
Fourth Crusade (1204), when it became part of the short-lived

John III Vatatzes (r. 1221–1254) conquered Macedonia, the theme was re-established as a separate province. In the 14th century, however, it again appears as combined with other provinces such as the themes of Boleron and Thessalonica or as the theme of "Serres and Strymon".
