British MuseumThe full extent of the Roman Empire at its height.Many places around the globe contain traces of the Roman Empire to this day. There are Roman ruins in Africa, the Middle East, and Europe; crumbled arenas, cracked columns, and stone walls still stand as a reminder of the ancient superpower. But just how big was the Roman Empire? The sprawling empire reached its peak in 117 C.E., when it stretched from the northern border of England down to North Africa and from the Atlantic Ocean in the west to the Persian Gulf in the east. While it was by no means the largest empire in world history, it was certainly impressive for its time.However, its size would ultimately lead to its downfall. By the fourth century C.E., the Roman Army had pulled back from some of the farther reaches of the territory to focus on impending threats to the heart of the realm. Then, in 286, the empire permanently split in half.The Western Roman Empire collapsed in 476, bringing an end to a power that had once seemed unstoppable. But the immense size of the Roman Empire cemented its legacy as one of historys most famous domains.The Expansion Of Rome Before It Became An EmpireAccording to legend, Rome was founded in 753 B.C.E. by Romulus, the citys first king. The Etruscans soon took over, but in 510 B.C.E., the Roman Republic was formed. It was at this point that the Romans set out to conquer their neighbors.By 272 B.C.E., the entire Italian peninsula was under Romes control. And in 241 B.C.E., at the end of the First Punic War against Carthage, the Romans seized their first foreign territory, Sicily. As Cicero later proclaimed, Sicily was the first who taught our ancestors how glorious a thing it was to rule over foreign nations.Over the next two centuries, Rome continued to grow, first conquering Sardinia and Corsica, then moving on to Spain, North Africa, and Anatolia. Soon, almost all of the land surrounding the Mediterranean Sea belonged to the Romans.During the Gallic Wars, between 58 and 50 B.C.E., Julius Caesar defeated the people of Gaul (including modern-day France, Belgium, Luxembourg, and Switzerland), adding to the ever-growing empire. It was during one of his conquests in present-day Turkey that Caesar purportedly declared, Veni, vidi, vici, or, I came, I saw, I conquered. Of course, he later crossed the Rubicon and declared himself dictator for life, which led to his assassination in 44 B.C.E.Anassagora/Wikimedia CommonsA statue of Julius Caesar in Turin, Italy.Caesars successor, Octavian, then claimed victory over Mark Antony and Cleopatra at the Battle of Actium in 31 B.C.E., bringing the majority of Egypt under Roman control. Four years later, the Roman Empire was officially established, with Octavian adopting the title Augustus as the first emperor.So, how big was the Roman Empire at its height?How Big Was The Roman Empire? Its True Size At Its PeakAfter Augustus seized power, Rome enjoyed a period of peace and prosperity known as the Pax Romana, which lasted from 27 B.C.E. until 180 C.E. During this time, the empire continued to expand. Emperor Claudius (41 C.E. to 54 C.E.) finished what Caesar had started and conquered Britain, while Trajan (98 C.E. to 117 C.E.) added Dacia (modern-day Romania) and Parthia (parts of modern-day Iran and Turkmenistan) to Romes territory, pushing the borders of the empire all the way to the Persian Gulf. Under Trajan, the size of the Roman Empire reached its peak.Indeed, Trajans successor, Hadrian (117 C.E. to 138 C.E.), set a limit to the empire. He built Hadrians Wall along the northernmost reaches of the Roman frontier, near the border of England and Scotland. {"div_id":"expansion-of-the-roman-empire.gif.b2156","plugin_url":"https:\/\/allthatsinteresting.com\/wordpress\/wp-content\/plugins\/gif-dog","attrs":{"src":"https:\/\/allthatsinteresting.com\/wordpress\/wp-content\/uploads\/2024\/06\/expansion-of-the-roman-empire.gif","alt":"Size Of The Roman Empire","width":"900","height":"855","class":"size-full wp-image-486280 post-img-landscape"},"base_url":"https:\/\/allthatsinteresting.com\/wordpress\/wp-content\/uploads\/2024\/06\/expansion-of-the-roman-empire.gif","base_dir":"\/vhosts\/all-that-is-interesting\/wordpress\/\/wp-content\/uploads\/2024\/06\/expansion-of-the-roman-empire.gif"}Smhur/Wikimedia CommonsThe Roman Republic and the Roman Empire expanded quickly, which later contributed to the fall of Rome.By this point, the size of the Roman Empire had grown to incredible proportions. It had a population of at least 45 million and spanned 50 modern countries. In terms of land mass, it covered nearly two million square miles about half the size of the United States and stretched from Portugal to Mesopotamia and England to Africa.But the size of the Roman Empire would also be one major factor in its collapse. How The Size Of Rome Led To Its CollapseThere were many issues that led to the fall of Rome, but the size of the Roman Empire was certainly a key one.At first, Romes vast expanse had been a source of pride to its citizens. The gradual conquest of land in Europe, Africa, Asia, and the Middle East had brought riches, slave labor, and new cultures into the empire. But as Roman expansion ceased, these resources increasingly dwindled. Meanwhile, though Rome had grown in part to protect itself, each land it conquered added to the territory it had to defend. More and more of its wealth was funneled into the empires army, but military rule could only do so much. Romes far-flung provinces had become impossible to govern.Johnnie Shannon/Wikimedia CommonsParts of Hadrians Wall, which marked the northern limits of the Roman Empire, still stand in England today.Near the end of the third century C.E., Emperor Diocletian devised a solution to the problem of Romes size. He split it up into the Western Roman Empire and the Eastern Roman Empire. The seat of the Western Roman Empire would be in Milan (though Rome maintained its status as a ceremonial capital), and the seat of the Eastern Roman Empire would be in Byzantium (later renamed Constantinople and then Istanbul).Initially, it seemed that Diocletian had solved the issues caused by the size of the Roman Empire. But the two empires began to drift apart, and the Western Roman Empire was increasingly battered by invasions from Germanic tribes. In 476 C.E., the Germanic leader Odoacer overthrew Romes emperor, Romulus Augustus, and the Western Roman Empire officially fell. Still, the Eastern Roman Empire continued until the 15th century (which is why theres some debate over when exactly the Roman Empire fell). So, how big was the Roman Empire? It never really grew any larger than it was under Trajan, as wars and plagues decimated its population in the years after his rule. There have certainly been larger empires in world history, and many countries today have more citizens than Rome ever did, but the Roman Empire continues to loom large in culture. Not only did it spread over much of the world, but it also left behind incredible traces of its lost might. In Roman ruins that still exist today, we can see a reflection of the Roman Empires ravenous sprawl across the globe.
