The borders of the Roman Empire , which fluctuated throughout the empire's history, were realised as a combination of military roads and linked forts, natural frontiers (most notably the Rhine and Danube rivers) and man-made fortifications which separated the lands of the empire from the countries beyond.
The word limes is sometimes used by modern scholars to denote the frontier of the Roman Empire but was not used by the Romans as such. After the third century it was an administrative term, indicating a military district, commanded by a dux limitis. [1]
The Latin noun limes had a number of different meanings: a path or balk marking off the boundaries of fields; a boundary line or marker; any road or path; any channel, such as a stream channel; or any distinction or difference between two things.
In Britannia the Empire built two walls one behind the other; for Mauretania there was a single wall with forts on both sides of it. In other places, such as Syria and Arabia Petraea, there was no continuous wall; instead there was a net of border settlements and forts occupied by the Roman army. In Dacia, the limes between the Black Sea and the Danube were a mix of the latter and the wall defenses: the Limes Moesiae was the conjunction of two, and sometimes three, lines of vallum , with a Great Camp and many minor camps spread through the fortifications.[ citation needed ]

In continental Europe, the borders were generally well defined, usually following the courses of major rivers such as the Rhine and the Danube. Nevertheless, those were not always the final border lines; the province of Dacia, modern Romania, was completely on the far side of the Danube, and the province of Germania Magna, which must not be confused with Germania Inferior and Germania Superior, was the land between the Rhine, the Danube and the Elbe (Although this province was lost three years after its creation as a result of the Battle of Teutoburg Forest).
In Great Britain both Hadrian and Antoninus Pius built defences to protect the province of Britannia from the Caledonians. Hadrian's Wall, constructed in 122 held a garrison of 50,000 soldiers, while the Antonine Wall, constructed between 142 and 144, was abandoned by 164 and briefly reoccupied in 208, under the reign of Septimius Severus.
The eastern borders changed many times, as the Roman Empire was facing two major powers, The Parthian Empire and the Sasanian Empire. The Parthians were a group of Iranian peoples ruling most of Greater Iran that is in modern-day Iran, western Iraq, Armenia and the Caucasus. [2] The Sasanians succeeded the Parthians in 224–226 and were recognised as one of the leading world powers alongside its neighbouring arch-rival the Roman (Byzantine) Empire for a period of more than 400 years.
At the greatest extent of the Empire, the southern border lay along the deserts of Arabia in the Egyptian region and the Sahara in North Africa, which represented a natural barrier against expansion. The Empire controlled the Mediterranean shores and the mountain ranges further inland. The Romans attempted twice to occupy the Siwa Oasis and finally used Siwa as a place of banishment. However, the Romans controlled the Nile many kilometres into Africa up to Syena, Berenice, Hyerasykaminos and even Qasr Ibrim (the southernmost of all), near the modern border between Egypt and Sudan, then Meroe, lying very near the tropic.[ citation needed ] The period in which each aforementioned town represented the final frontier of Rome is uncertain.
In Africa the Romans controlled the area north of the Sahara, from the Atlantic Ocean to Egypt, with the borders being controlled by many sections of fortifications such as the Limes Arabicus (called the Limes Uranus), Limes Mauretaniae, Fossatum Africae, Fossa Regia, Limes Tripolitanus, Limes Numidiae, etc. [3]
In the south of Mauritania Tingitana Romans made a limes in the third century, just north of the area of actual Casablanca near Sala and stretching to Volubilis.
Septimius Severus expanded the "Limes Tripolitanus" dramatically, even briefly holding a military presence in the Garamantian capital Garama in AD 203. Much of the initial campaigning success was achieved by Quintus Anicius Faustus, the legate of Legio III Augusta.
Following his African conquests, the Roman Empire may have reached its greatest extent during the reign of Septimius Severus, [4] [5] under whom the empire encompassed an area of 5 million square kilometres (2 million square miles). [4]
Lucius Septimius Severus was a Roman politician who served as emperor from 193 to 211. He was born in Leptis Magna in the Roman province of Africa. As a young man he advanced through the customary succession of offices under the reigns of Marcus Aurelius and Commodus. Severus was the final contender to seize power after the death of the emperor Pertinax in 193 during the Year of the Five Emperors.
The 2nd century is the period from AD 101 through AD 200 (CC) in accordance with the Julian calendar. It is considered part of the Classical era, epoch, or historical period.
Limes is a term used primarily for the Germanic border defence or delimiting system of Ancient Rome marking the borders of the Roman Empire. The term has been extended in modern times to refer to the frontier defences in other parts of the empire, such as in the east and in Africa.
Legio I Minervia was a legion of the Imperial Roman army founded in AD 82 by emperor Domitian, for his campaign against the Germanic tribe of the Chatti. Its cognomen refers to the goddess Minerva, the legion's protector. There are still records of the I Minervia in the Rhine border region in the middle of the 4th century. The legion's emblem is an image of goddess Minerva.
Legio I Adiutrix, was a legion of the Imperial Roman army founded in AD 68, possibly by Galba when he rebelled against emperor Nero. The last record mentioning the Adiutrix is in 344, when it was stationed at Brigetio, in the Roman province of Pannonia. The emblem of the legion was a capricorn, used along with the winged horse Pegasus, on the helmets the symbol used by I Adiutrix legionaries was a dolphin.
Legio XXX Ulpia Victrix was a legion of the Imperial Roman army. Their emblems were the gods Neptune and Jupiter and the Capricorn. Ulpia is Trajan's own gens, while the cognomen "Victrix" means "victorious," and it was awarded after their valiant behaviour in the Dacian Wars. The legion was active until the disbandment of the Rhine frontier in the beginning of the 5th century.
The Roman provinces were the administrative regions of Ancient Rome outside Roman Italy that were controlled by the Romans under the Roman Republic and later the Roman Empire. Each province was ruled by a Roman appointed as governor.
The Limes Germanicus, or 'Germanic Limes', is the name given in modern times to a line of frontier fortifications that bounded the ancient Roman provinces of Germania Inferior, Germania Superior and Raetia, dividing the Roman Empire and the unsubdued Germanic tribes from the years 83 to about 260 AD. The frontier used either a natural boundary such as a river or typically an earth bank and ditch with a wooden palisade and watchtowers at intervals, and a system of linked forts was built behind them.
The Marcomannic Wars were a series of wars lasting from about AD 166 until 180. These wars pitted the Roman Empire against principally the Germanic Marcomanni and Quadi and the Sarmatian Iazyges; there were related conflicts with several other Germanic, Sarmatian, and Gothic peoples along both sides of the whole length of the Roman Empire's northeastern European border, the river Danube.
Roman military borders and fortifications were part of a grand strategy of territorial defense in the Roman Empire, although this is a matter of debate. By the early 2nd century, the Roman Empire had reached the peak of its territorial expansion and rather than constantly expanding their borders as earlier in the Empire and Republic, the Romans solidified their position by fortifying their strategic position with a series of fortifications and established lines of defense. Historian Adrian Goldsworthy argues that the Romans had reached the natural limits which their military traditions afforded them conquest over and that beyond the borders of the early-to-mid Empire lay peoples whose military traditions made them militarily unconquerable, despite many Roman battle victories. In particular, Goldsworthy argues that the cavalry-based warfare of the Parthians, Sarmatians and Persians presented a major challenge to the expansion of Rome's infantry-based armies.
The Limes Tripolitanus was a frontier zone of defence of the Roman Empire, built in the south of what is now Tunisia and the northwest of Libya. It was primarily intended as a protection for the tripolitanian cities of Leptis Magna, Sabratha and Oea in Roman Libya.
The Moesian Limes is the modern term given to a linked series of Roman forts on the northern frontier of the Roman province of Moesia along the Danube between the Black Sea shore and Pannonia and dating from the 1st century AD. It was the eastern section of the so-called Danubian Limes and protected the Roman provinces of Upper and Lower Moesia south of the river. The eastern section is often called the limes Scythiae minoris as it was located in the late Roman province of Scythia Minor.
The Wall of Severus is believed to be a defensive fortification built by the Roman Emperor Septimius Severus during his military campaigns in northern Britannia in the early 3rd century. Although the structure is mentioned in several classical texts, its precise location is academically disputed due to inconsistencies between sources. Scholarly consensus believes they are most likely referring to the Antonine Wall. However, Hadrian's Wall and Offa's Dyke have both been suggested as possible candidates. Archaeological evidence has been discovered showing parts of Offa's Dyke, on the England-Wales border, is at least as old as the mid 5th century, predating the 8th-century reign of the Saxon King Offa of Mercia by 300 years.
The area of North Africa which has been known as Libya since 1911 was under Roman domination between 146 BC and 672 AD. The Latin name Libya at the time referred to the continent of Africa in general. What is now coastal Libya was known as Tripolitania and Pentapolis, divided between the Africa province in the west, and Crete and Cyrenaica in the east. In 296 AD, the Emperor Diocletian separated the administration of Crete from Cyrenaica and in the latter formed the new provinces of "Upper Libya" and "Lower Libya", using the term Libya as a political state for the first time in history.
Gaius Julius Sohaemus was a Roman client king of Armenia.

The frontier of the Roman Empire in Britain is sometimes styled Limes Britannicus by authors for the boundaries, including fortifications and defensive ramparts, that were built to protect Roman Britain. These defences existed from the 1st to the 5th centuries AD and ran through the territory of present-day England, Scotland and Wales.
The Dacian Limes is the generic modern term given to a collection of ramparts and linked series of Roman forts on the frontiers of the Roman province of Dacia dating from the early 2nd century AD. They ran for about 1,000 km and included the:
The Geopolitics of the Roman Empire deals with the "inalienable relationship between geography and politics of the Roman Empire". Once the Roman Empire had reached its natural borders, the location of potential threats to the empire and Roman troop locations played a major role in the elevation of Roman Emperors. Access to the troops, their location were crucial to the empire's internal politics, civil wars, and the eventual Fall of the Western Roman Empire.
