[edit] History
In the year 743, the Byzantine emperor Constantine V retook Constantinople from the rebellious Count of the Opsician thema, Artabasdus. Soon after, Constantine broke up the rebellious Opsician theme. Apparently, roughly half of the soldiers assigned to the theme were used to create six new military units known as the tagmata (brigades). In order to ensure their loyalty, the commanders were directly responsible to the emperor.
These new units were assigned to the capital, the former Opsician theme, and the theme of Thrace. The four most prestigious tagmata, in order, were the Scholae (Gr. Σχολαι, "Scholars"), the Excubitors (Gr. Εξκουβιτοι, "Watchers"); the Aritmoi (Gr. Αριτμοι, "Numbers") or Vigiles (Gr. υιγλα, "Watch"), and the Hikanatoi (Gr. Ικανατοι, "Worthies"). All of these were cavalry units consisting of from 1-6,000 men each. The Numeroi (Gr. Νουμηροι, "Bathhouse boys"), Optimatoi (Gr. Οπτιματοι, "Best"), and ton Teikhon (Gr. Tών Τειχών, "of the Walls") were infantry tagmata.
Some of the tagmata (especially the Scholae) began as an honorary post for well-connected citizens (δυνατοι). One emperor even amused himself by placing it on the active duty roster for an upcoming campaign only to see the panicked reaction of its senators, aristocrats, and merchants. Other units, such as the Vigiles, were used basically as policemen and firefighters for the capital Constantinople. Eventually, however, the tagmata all became practical, crack units.
Despite the main purpose of suppressing military rebellion, the tagmata turned out to have practical uses. For one, they were more mobile than the theme troops. While they still held land in return for military service, the tagmata tended to sublet their estates and were primarily used for offensive action rather than garrison duty. This made them a good supplement to the theme troops, who were more concerned with local defense.
The following table illustrates the Tagmatic structure as found in the Tagma of the Scholae, circa 902-936
| Thematic Equivalent | Name | No. of personnel | No. of subordinate units | Officer in command |
|---|---|---|---|---|
| Themata | Tagmata | 4 000 | 2 Merẽ | Domestic |
| Turma, Meros | n/a | 2 000 | 2 Drungi | Topoteretae |
| Drungus | Drungus | 1 000 | 5 Banda | Drungary |
| Bandum | Bandum | 200 | 2 "Centuria" | Count |
| "Century" | 100 | 10 "Contubernia" | Centarch | |
| "Contubernium" | 10 | 1 "Vanguard*" + 1 "Rear Guard*" | Decarch | |
| "Vanguard*" | 5 | n/a | Pentrarch | |
| "Rear Guard*" | 4 | n/a | Tetrarch |
- Note: At the Banda level, Thematic and Tagmatic unit names followed the same hierarchy, excluding the Pentecontarchs. Terms in quotations are contignuations of the roman Legion system or * direct translations.[1]
