Cohors prima Ulpia Galatarum ("1st Ulpian cohort of Galatians") was a Roman auxiliary cohort of infantry.
Name Ulpia: Ulpian. The Imperial family name shows a link to the emperor Trajan (Marcus Ulpius Traianus). Galatarum: Galatians. At the time the unit was raised, the recruits came from the Roman province of Galatia.
Since there is no indication for milliaria and equitata, the unit was a Cohors quingenaria peditata with a nominal strength of 480 infantry (6 centuriae with 80 men each).
History The unit was probably raised by Trajan in preparation for his Parthian campaign around 112/113.Bennett (2011) 267 It is attested on military diplomas for the province of Syria Palaestina issued in 136/137, 139, 142, 149/160, 158, 160 and 186.Spaul (2000) 390,395 In 238 it was at Aquileia in Italy, presumably as part of the exercitus Aquilensis.
