Cohors I Thracum (Britannia)

from Wikipedia, the free encyclopedia

The Cohors I Thracum [civium Romanorum] [equitata] ( German  1st cohort of the Thracians [of the Roman citizens] [partly mounted] ) was a Roman auxiliary unit . It is evidenced by military diplomas and inscriptions.

Name components

  • I : The Roman number stands for the ordinal number, the first ( Latin prima ). Hence the name of this military unit is pronounced as Cohors prima ...
  • Thracum : The soldiers of the cohort were recruited from the Thracian people on the territory of the Roman province of Thrace when the unit was established .
  • civium Romanorum : the Roman citizen. The soldiers of the unit had been granted Roman citizenship at one point in time. However, this did not apply to soldiers who were accepted into the unit after this point in time. They received Roman citizenship only with their honorable farewell ( Honesta missio ) after 25 years of service. The addition appears in an inscription.
  • equitata : partially mounted. The unit was a mixed association of infantry and cavalry. The addition appears in an inscription.

Since there is no evidence of the addition of milliaria (1000 men) to the name , the unit was a Cohors quingenaria equitata . The nominal strength of the cohort was 600 men (480 infantry and 120 horsemen), consisting of 6 centuries of infantry with 80 men each and 4 tower cavalry with 30 horsemen each.

history

The cohort was stationed in the province of Britannia . It is listed on military diplomas for the years AD 122 to 178.

Unity has been attested in Britain since Flavian times. A diploma is the first to prove it in the province. In the diploma, the cohort is listed as part of the troops (see Roman Forces in Britannia ) that were stationed in the province. Other diplomas, dated 127 to 178, prove unity in the same province.

The last evidence of the cohort is based on two inscriptions dated 205/208.

Locations

Cohort locations in Britain may have been:

Remarks

  1. The scenario given here follows the explanations of John Spaul . It is based on a single Cohors I Thracum , which was stationed in the province of Britannia . Other historians, however, assume that two different cohorts, the Cohors I Thracum civium Romanorum and the Cohors I Thracum equitata , were stationed in Britain.
  2. a b The assignment to the unit is assumed, but is not certain.
