Roman army was among the most homogenous Roman structures, and the organization of the army in Egypt differed little from its organization elsewhere in the Roman Empire. The
Roman legions were recruited from
Roman citizens and the
Roman auxilia recruited from the non-citizen subjects. Egypt was unique in that its garrison was commanded by the
praefectus Aegypti, an official of the equestrian order, rather than, as in other provinces, a governor of the senatorial class. Alexandria was the Mediterranean's second city in the early Roman empire, the cultural capital of the Greek East and rival to Rome under Antony and Cleopatra. Because only a few papyri are preserved from the area, little more is known about the legionaries' everyday life than is known from other provinces of the empire, and little evidence exists of the military practices of the prefect and his officers. Most papyri have been found in
Middle Egypt's villages, and the texts are primarily concerned with local affairs, rarely giving space to high politics and military matters. Not much is known about the military encampments of the
Roman imperial period, since many are underwater or have been built over and because
Egyptian archaeology has traditionally taken little interest in Roman sites. Because they supply a record of soldiers' service history, six bronze
Roman military diplomas dating between 83 and 206 are the main source of documentary evidence for the in Egypt; these inscribed certificates rewarded 25 or 26 years of military service in the with Roman citizenship and the right of
conubium. That the army was more Greek-speaking than in other provinces is certain. The heart of the Army of Egypt was the Nicopolis garrison at Alexandria, with at least one legion permanently stationed there, along with a strong force of cavalry. These troops would both guard the residence of the against uprisings among the Alexandrians and were poised to march quickly to any point at the prefect's command. At Alexandria too was the , the provincial fleet of the
Roman Navy in Egypt. In the 2nd and 3rd centuries, there were around 8,000 soldiers at Alexandria, a fraction of the
megalopolis's huge population. Initially, the legionary garrison of Roman Egypt consisted of three legions: the
Legio III Cyrenaica, the
Legio XXII Deiotariana, and one other legion. The station and identity of this third legion is not known for sure, and it is not known precisely when it was withdrawn from Egypt, though it was certainly before 23 AD, during the reign of
Tiberius (). In the reign of Tiberius's step-father and predecessor Augustus, the legions had been stationed at Nicopolis and at Egyptian Babylon, and perhaps at
Thebes. After August 119, the
III Cyrenaica was ordered out of Egypt; the
XXII Deiotariana was transferred sometime afterwards, and before 127/8, the
Legio II Traiana arrived, to remain as the main component of the Army of Egypt for two centuries. After some fluctuations in the size and positions of the garrison in the early decades of Roman Egypt, relating to the conquest and pacification of the country, the contingent was mostly stable during the
Principate, increasing somewhat towards the end of the 2nd century, and with some individual formations remaining in Egypt for centuries at a time. Three or four
alae of cavalry were stationed in Egypt, each
ala numbering around 500 horsemen. There were between seven and ten
cohortes of infantry, each
cohors about 500 strong, although some were
cohortes equitatae – mixed units of 600 men, with infantry and cavalry in a roughly 4:1 ratio. Besides the stationed at Alexandria, at least three detachments permanently garrisoned the southern border, on the Nile's
First Cataract around
Philae and Syene (
Aswan), protecting Egypt from enemies to the south and guarding against rebellion in the
Thebaid. Besides the main garrison at Alexandrian Nicopolis and the southern border force, the disposition of the rest of the Army of Egypt is not clear, though many soldiers are known to have been stationed at various outposts (), including those defending roads and remote natural resources from attack. Roman detachments,
centuriones, and
beneficiarii maintained order in the Nile Valley, but about their duties little is known, as little evidence survives, though they were, in addition to the
strategoi of the
nomoi, the prime local representatives of the Roman state. Archaeological work led by
Hélène Cuvigny has revealed many
ostraca (inscribed ceramic fragments) which give unprecedently detailed information on the lives of soldiers stationed in the
Eastern Desert along the
Coptos–
Myos Hormos road and at the imperial granite quarry at
Mons Claudianus. Another Roman outpost, known from an inscription, existed on
Farasan, the chief island of the
Red Sea's
Farasan Islands off the west coast of the
Arabian Peninsula. As in other provinces, many of the Roman soldiers in Egypt were recruited locally, not only among the non-citizen , but among the legionaries as well, who were required to have Roman citizenship. An increasing proportion of the Army of Egypt was of local origin in the reign of the
Flavian dynasty, with an even higher proportion – as many as three quarters of legionaries – under the
Severan dynasty. Of these, around one third were themselves the offspring () of soldiers, raised in the
canabae settlements surrounding the army's base at Nicopolis, while only about one eighth were Alexandrian citizens. Egyptians were given Roman-style Latin names on joining the army; unlike in other provinces, indigenous names are nearly unknown among the local soldiers of the Army of Egypt. One of the surviving military diplomas lists the soldier's birthplace as
Coptos, while others demonstrate that soldiers and centurions from elsewhere retired to Egypt: veterans from
Chios and
Hippo Regius (or
Hippos) are named. Evidence from the 2nd century suggests most came from Egypt, with others drawn from the provinces of
Africa and
Syria, and from Roman
Asia Minor. from the Balkans, who served throughout the Roman army, also served in Egypt: many
Dacian names are known from
ostraca in the Trajanic period, perhaps connected with the recruitment of
Dacians during and after
Trajan's Dacian Wars; they are predominantly cavalrymen's names, with some infantrymen's.
Thracians, common in the army in other Roman provinces, were also present, and an auxiliary diploma from the Egyptian garrison has been found in
Thracia. Two diplomas connect Army of Egypt veterans with Syria, including one naming
Apamea. Large numbers of recruits mustered in Asia Minor may have supplemented the garrison after the
Diaspora Revolt, a Jewish uprising in Egypt, Libya and Cyprus. == Society ==
