Top 10 Most Important Empires In World History


Being an imperial power doesn’t impress people the way it used to.  A century ago, countries strived to be a dominating world power and were willing to fight wars to either acquire an Empire, or hold on to the one they already had.  Nowadays, of course, in this “kinder, gentler” world, imperialism is considered politically incorrect.  As a result—and because maintaining an empire is prohibitively expensive—they are basically no more, though a few remnants hang on (such as the Falkland Islands for the British and the Comoro Islands for France).  At one time, however, they were all the rage, with some of them extending around the globe and a few of them lasting for hundreds and, in a few cases, even thousands of years.

So which were the largest or most important ones, and which lasted the longest?  I realize that how one defines “important” can be subjective; I define it to mean its impact upon history or, more precisely, the ways in which it shaped the geopolitical map we see today.  With that in mind, then, below is my top ten list of the ten largest, most powerful and important Empires in history.

10.  The Mayan Empire (ca. 2000 BCE-1540 CE)


How does the Mayan Empire make it onto the list alongside such well-known empires like the Roman, British, and Mongol Empires?  Easy.  It holds the record for the longest running empire—almost 3500 years!  That’s more than twice as long as the Roman Empire, and 1500 years longer than the various Chinese dynasties combined!  While very little is known about its first 3,000 years, its demise and brief interaction with the Spanish in the 16th century is the stuff of legends (see the Mel Gibson-directed film Apocalypto to get a good idea of what the Mayan Empire looked like at its height).  Today, all we have left of the Mayans is their impressive pyramid-like structures scattered across the Yucatan peninsula, and a doomsday calendar that seems to have everybody up in arms nowadays.

9.  The French Empire (1534-1962)


Eventually becoming the second-largest empire in history (second only to the British Empire), at its zenith the French Colonial Empire extended over 4.9 million square miles, and covered almost 1/10 of the Earth’s total land area.  Its influence made French one of the most widely-spoken languages in the world for a time, and brought French architecture, culture, and cuisine to the four corners of the globe. Alas, like all the great European empires, its collapse came about incrementally over a long period of time, as it lost territories to other emerging nations—especially to the British—and it suffered through two World Wars, which drained it financially. Though it continued to hold onto to some of its territories well into the 20th century (and still does to this day), by 1962, with the granting of independence to rebellious Algeria, the French Empire was basically no more, bringing a close to a long and cultured era in human history.

8.  The Spanish Empire (1492-1976)


One of the first global empires, at its height it possessed territories and colonies in Europe, the Americas, Africa, Asia and Oceania, making it one of the most important political and economic powers in the world for several hundred years.  Its establishment in the 15th century also ushered in the modern global era, and five centuries of European dominance of global affairs before competition from other European powers—particularly the French and British—weakened Spain to the point that, by the end of the 19th century, it was but a shadow of its former greatness. The end didn’t finally come until the 1970s, however, when it granted its last colonies in Africa and South America their independence, spelling finito to 600 years of Spanish colonialism.  Its chief contribution came in its discovery of the New World in 1492 and the spread of Christianity to the western world, both of which was to dramatically change the geo-political dynamics of the planet and lay the foundation for the modern western world.

7.  The Qing Dynasty (1644-1912)


This was the last ruling dynasty of China before the country became a Republic, bringing an end to many hundreds of years of imperial rule. Preceded by the better-known Ming Dynasty, the Qing dynasty was founded by the Manchu clan Aisin Gioro in what is today Manchuria in 1644.  It grew quickly until, by the 18th century, it covered all of what is today’s modern China, Mongolia, and even parts of Siberia—an area of over 5.7 million square miles (and making it the 5th largest empire in history, according to land mass.)  The Qing Dynasty was finally overthrown following the Xinhai Revolution, however, when the Empress Dowager Longyu abdicated on behalf of the last emperor, Puyi, in February of 1912, bringing an end to a long line of Emperors stretching back over 1500 years.  Not a bad run by any standards!

6.  The Umayyad Caliphate (661-750)


I bet you’ve never heard of this one, but it proved to be one of the fastest growing—though shortest-lived—Empires in history.  Organized in the aftermath of the death of the venerated prophet Muhammad, it was the mechanism by which Islam was spread across the Middle East and into North Africa, sweeping aside everything in its path.  Actually, the Umayyad Caliphate was the second of the four Islamic caliphates established after the death of Muhammad but, at its height, it would cover more than five million square miles, making it the largest empire the world had yet seen (modern Arab nationalism regards the period of the Umayyads as part of the Arab Golden Age of Islam).  Though it was eventually superseded by various other caliphates and empires (including the Ottoman Empire), it laid the foundation for what was to be a nearly unbroken string of Muslim control in the region, that continues to this day.

5.  The Achaemenid Empire (ca. 550-330 BCE)


More commonly referred to as the Medo-Persian Empire, this Asian Empire was the largest one in ancient history which, at its height, extended from the Indus valley of modern day Pakistan to Libya, and into the Balkans.  Forged by Cyrus the Great, it is best remembered as the chief foe of the Greek city states during the Greco-Persian Wars, for emancipating its slaves and releasing the Jews from their Babylonian captivity, and for instituting the usage of official languages throughout its territories.  It wasn’t very long, however, before it fell victim to Alexander the Great in the 4th century BCE, and was quickly defeated and absorbed into Alexander’s own vast, but short-lived, Empire.

Upon his death, it splintered into two smaller Empires, the Ptolemaic Kingdom and Seleucid Empire, as well as into other minor territories, many of which gained independence after its collapse.  Perhaps its greatest contribution was in its creation of a centralized administration that kept it running efficiently and profitably for centuries, and served as a model for future and modern governments.  So these are the folks that invented bureaucracy, is it?

4.  The Ottoman Empire (1299-1922)


The Ottoman Empire was one of the largest and longest lasting empires in history.  During its height (under Suleiman the Magnificent) in the 16th century, it stretched from the southern borders of the Holy Roman Empire to the Persian Gulf, and from the Caspian Sea to modern day Algeria, giving it de facto control of much of southeast Europe, Western Asia and North Africa.  At the beginning of the 17th century the empire contained no fewer than 32 provinces, along with numerous vassal states, making it one of the truly great empires whose influence continues to be felt to this day.

As is the case with most large empires, however, ethnic and religious tensions, and increasing competition from other emerging powers, whittled away at the Ottoman’s power until it finally began dissolving in the 19th century.  In many ways, the circumstances surrounding the Ottoman Empire’s fall closely paralleled those surrounding the decline of the Roman Empire, particularly in regards to the ongoing tensions between the Empire’s different ethnic groups, and the various governments’ inability to deal with these tensions.  Attempts to improve cultural rights and civil liberties came too late to reverse its demise, though it did lay the foundation for secularist governments in the Muslim world, as exemplified by modern-day Turkey.

3.  The Mongol Empire (1206-1368)


Though short-lived as Empires go—it lasted a mere 162 years—while it was around, few were as frightening, or grew as quickly, as this one.  Under the leadership of Ghengis Khan (1163-1227), it started small—basically just present-day Mongolia—but within seventy years it had grown into the largest contiguous land Empire in human history, eventually stretching from Eastern Europe to the Sea of Japan.  At its height, it covered an area of 9 million square miles, and held sway over a population of 100 million.

It would probably have been even larger—and possibly have lasted longer—had it managed to invade Japan, but its fleet lost bouts with first-class tsunamis in 1274 and 1281, ending Kublai Khan’s plans to expand eastward.  By the middle of fourteenth century, the empire began slowly falling apart through infighting and political instability until it finally folded, with its far-flung territories breaking away or being absorbed by other emerging powers.  While it existed, however, few Empires had as big an impact on trade, religion, and culture in Asia as did the Mongols.

2.  The British Empire (1603 to 1997)


Though it lasted a mere 400 years, no empire was larger than the one the comparatively-small island nation of Great Britain was able to maintain until fairly recently.  How big was it?  At its zenith in 1922, the British Empire held sway over nearly half a billion people (a fifth of the world’s population at the time) and covered more than 13 million square miles (almost a quarter of the Earth’s total land area)!  Not bad for a country slightly smaller than the state of Oregon.  In fact, at one point the sun never set on the British Empire, not because God couldn’t trust an Englishman in the dark, but because of its global reach (with colonies and possessions on every continent—including, believe it or not, Antarctica).

Alas, all good things must come to an end, and that end came in the twentieth century, when two World Wars drained England financially, making it cheaper to dissolve her empire than keep it.  Of course, once they lost India in 1947 it was all over; except for a couple of small possessions (the aforementioned Falkland Islands and a few islands scattered around the globe), the sun really has set on the British Empire.  Its most important possession remains Gibraltar, the gateway to the Mediterranean, and one that is supposed to remain in British hands as long as its population of Barbary Macaques—a type of obnoxious monkey—remains on the peninsula.

1.  The Roman Empire (27 BCE to 1453)


This is a no-brainer, as absolutely no Empire is as well known and has been as thoroughly studied as is the one that owned the Mediterranean and much of Europe for almost 1,500 years.  Founded in 27 BCE, when the Roman senate granted Octavian the title of Augustus—thereby ending the old Roman Republic (which itself had already stood a good 500 years)—it ended nearly 1500 years later when the Ottoman Turks, under Mehmed II, sacked the last vestiges of the old Empire’s capitol, Constantinople, in 1453. Of course, by that time it was a mere shadow of its former glory (and was no longer even ruled from Rome) but, at its zenith in 117 CE, it was the most powerful nation on the planet, bar none.  While it wasn’t the largest, or even the longest-lasting Empire in history, its influence on western culture—especially in regards to architecture, language, literature, art, and science—cannot be underestimated.  In fact, it’s difficult to imagine how the world would look today if there hadn’t been a Roman Empire those many centuries ago.

Others empires worthy of note: The Assyrian Empire (mentioned prominently in the Bible), the Byzantine Empire (the long-lived successor to the Roman Empire), The Holy Roman Empire (which owned Europe for nearly 900 years), the Egyptian Empire (regional but nearly as famous as the Roman Empire), and the Greek—or, more precisely—the Macedonian Empire (one of the shortest-lived but most powerful empires in the world, under Alexander the Great).

    ‘1. The Roman Empire (27 BCE to 1453)’

    The Roman Empire did not last from 27 BCE to 1453.
    The Empire was split into two parts, the dates usually given for this are either:
    285 AD, under Diocletian and the Tetrarchy or
    395 AD, when Theodosius split the Empire between his two sons, giving one the Western part, the the other the Eastern one.
    The Western Roman Empire was mostly made up of modern day England, France, Spain, Portugal, and Italy.
    The Western Roman fell around 476 AD after several pressures, including the Huns at the Sack of Rome and various ‘tribes’ at it’s doorstep.

    The Eastern Roman Empire, also known as the Byzantine Empire fared a bit better. It was even able to reunify Rome and Constantinople, though not on the scale of Rome. However, as time marched on, their power declined and they fell when the Ottomans took Constantinople in 1453.

    To conclude,
    The Roman Empire (27 BCE-285 AD)
    The Western Roman Empire (285 AD-476 AD)
    The Eastern Roman/Byzantine Empire (285 AD-1453 AD)
    The complete unified Roman Empire ceased to exist in 285 AD, instead there were two parts. You [the author] have made the slight error that the Roman Empire was the Byzantine Emperor, those are my two cents on this.

    Best Regards

  2. Yes, what about the Austro-Hungarian Empire – if we talk about “Important Empires”. The author of the article made some mistake here, if we talk about important – not biggest, longest etc. This looks like a highschool article with a touch of “hollywood history”.

  3. ancient indian empires like the Mauryan and Guptas were most IMPORTANT in terms of knowledge and education…such large population even then ,they never had the time to move out of the subcontinent.

  4. Oh andHan empire WAs more advanceed and civilized than Roman empire. Tang empire was far more advanced and civilized than ANY Islamic thing in the medieval times.

    I would place Spain first since they were the first Europe power house who opened the doors to America for the rest of Europe. At one point the owned most of Latin America and a huge chunk of what is now the USA. They established the fist city in what is now the USA which is still present with the same name: St Augustine Florida founded in 1565. And still has its original Spanish coat of arms. They also ruled parts of Europe” Holland, Italy etc Queen Isabel is probably the most powerful ruler in history and many historical events were done under her period. Heck she kicked the Arabs out of Europe.

  6. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, 23% of the world population at the time, and by 1920, it covered 35,500,000 km2 (13,700,000 sq mi), 24% of the Earth’s total land area.

  7. Spain only APPEARED to have the biggest empire, the only problem though was that at least 1/2 of it was usurped by the takeover of Portugal by Phillip of Spain from 1580 until 1640. As a result of that tragic event, Portugal lost most of its strongholds / territories in Asia.

    I love how Hispanics complain that Portugal took more land in South America than they should have. To that I say that those were very different times, and back then it was a survival of the fittest game…some got more, and some got less. Let me remind that the Philippines were actually within the Portuguese part of the world as designated by the parameters of the Tordesillas treaty outlined by the pope. So Spain got away with that. All is fair in love and war.

    Without question, the Portuguese empire was the first global empire and effectively the pioneers of globalization. They introduced the world to itself! The global commercial economy was controlled by Portugal. Portugal spearheaded the Renaissance and mapped the world. There is hardly any place in the world that was not touched, influenced by Portugal in some way, shape or form, either linguistically, culturally, religiously, architecturally, technologically/scientifically, intellectually, etc, etc. Portugal was great little country that was greater than the sum of its parts.

    Today, the Portuguese language is spoken officially by some 260 million people, on 5 continents. It is the 3rd most spoken European language, and the most spoken language of Souther Hemisphere. Powerful countries such as the USA, China, Japan, India, etc., are major trading partners of the Community of Portuguese Speaking Countries known as CPLP. Brazil alone has the 5th strongest economy in the world! Another remarkable thing is that all of the above mentioned countries, and many, many more, are fervently learning the Portuguese language, as they realize the importance of knowing a language that is day by day more important in global trade. Furthermore, Portuguese has been added to the school curriculums of countries like: Japan, China, India, South Africa, Namibia, Senegal, USA, Canada, Ukraine, Turkey, Australia, Korea, France, Colombia, Venezuela, Argentina, Paraguay, Uruguay, and many more. They all want membership in CPLP that’s how en vogue the Portuguese language has become! Additionally, the Portuguese language is a compulsory subject in a few countries Uruguay being one of them.
