The Greatest Empires in World History

The Greatest Empires in World History Which was the Biggest Empire Ever? ChaptersWhat is an Empire?The First EmpiresThe Roman EmpireThe Mongol EmpireThe Ottoman EmpireThe Qing DynastyThe Russian EmpireThe British EmpireIf you spend ten minutes looking through history, you’ll certainly notice that this word ‘empire’ comes up an awful lot: the Roman Empire, the British Empire, etc. But what exactly do we mean when we say this? What does this word actually refer to? And, importantly, what is the difference between a kingdom, just a big country, and an empire?In this article, we’ll look at what an empire actually is, how the term is used in history, and where this whole idea started. We’ll also consider the biggest empires ever â€" longer articles about which you’ll find links to â€" and the factors that brought them into existence and then made them decline.Julius Caesar, whilst not officially an emperor, helped to establish the Roman Empire.semantic, meaning that it is a problem of language.Conquest and TerritoriesIn the first case, historians h ave designated as empires groups of territories that are all subject to one ruler â€" directly or indirectly. This means that whilst Russia now might be very large, it doesn’t mean it’s an empire.But, if it were to invade Mongolia and replace its government, then we would have something of an empire: two territories â€" or more, if it then went on to conquer China â€" would now be under the control of one ruler or government. As such, empires often show a significant ethnic, religious, linguistic, and cultural diversity.Let’s take the Ottoman Empire as another example. At one point, countries as diverse as Egypt, Bulgaria, Greece, and Lebanon were all under the domination of the Ottomans, who were based primarily in Turkey. These countries made up different ‘eyalet’ â€" or administrative units â€" of the Empire and were ruled by governors under the supervision of the Sultan or Emperor. This subordination, following imperial expansion and conquest, is thought to be a defini ng feature of an empire.Land and SeaIt is important to point out that there are two main types of empire within this idea. These are known as ‘terrestrial empires’ and ‘thalassocracies’, the first being empires conquered by land and the latter being those dominated by sea.The Mongol Empire is a great example of the former, as it spread outward, under Genghis Khan, from the Mongolian steppes. At the start of the empire, Genghis sent invasions in all directions to defeat and reign over as much land as quickly as possible.Whilst terrestrial empires are often contiguous â€" meaning all joined up â€" thalassocracies, or sea empires, do not need to be. The British Empire is an example of this, as it captured territories across the world â€" islands and ports as much as countries â€" through its incredibly powerful navy.The Name ‘Empire’The second definition of an empire is essentially that it calls itself an empire. This happens when a ruler changes his title of ‘king’, sa y, to that of ‘emperor’. This happened quite a lot.The Russian Empire is a famous example. Here, the kings had been engaging in imperial activity since Ivan the Great and even before â€" conquering territories and the like. Yet, it wasn’t until 1721 that Peter the Great decided to call Russia an Empire, changing its official name from a tsardom.The Roman Empire did something quite similar, as, whilst Octavian, or Augustus, took the title of Emperor, the Roman Senate in Rome had been expanding its borders for a long time previous to this.On the flip side, Korea, in 1897, started calling itself the Great Korean Empire, even though it owned no further land than Korea and was swallowed up eight years later by Japan.Decline: Why do Empires Fall?It’s something of a truism these days that ‘all empires fall’, no matter the prosperity or peace that they may bring to their people eventually. Herodotus, the Greek historian who lived even before the Roman Empire, already knew this. Nonetheless, historians today are still not one hundred percent agreed as to why empires collapse. They all do, however â€" usually as a result of their rulers becoming complacent and weak. Others, such as the Mongolian Empire, might become too big to manage, whilst others still faced invasions from outside â€" such as the Roman and the Qing empires. Four of the empires we look at collapsed â€" or were seriously weakened â€" due to war. It just happened to be the same war that did it!The First EmpiresImperial activity has probably been going on since human civilization first existed. Yet, the first we know about for sure is the Egyptian empire of about 3000BC, in which King Narmer of Egypt’s Upper Valley conquered the Lower Valley and brought it all under one rule. Some six hundred years later, the Akkadian Empire conquered much of Mesopotamia, which now makes up Iraq, Kuwait, and parts of Syria, Saudi Arabia, and Turkey.The Shang and the Zhou Empires, both in China between 1500 a nd 770BC, were both huge and pre-existed the Roman Empire by over seven centuries.The Roman EmpireHowever, it was the Romans who first used the term ‘empire’ as we know it now, deriving as it does from the Latin ‘imperator’, meaning commander. The Romans really set the bar for subsequent western imperialism, setting the administrative and political bases for later western governments.The Roman Empire lasted between 27BC and 476CE and, at its peak under Emperor Trajan, ruled over twenty-one percent of the population of the world at the time â€" stretching from Persia in the east to England in the west with the Mediterranean as its heart.

After that, he set out to conquer the world, and he wasn’t too far off succeeding. His empire stretched from Beijing in East Asia to the Danube and the Persian Gulf in the west â€" a whopping nine million square miles.Yet, despite establishing an unprecedented period of peace in the lands he conquered â€" known as the Pax Mongolica â€" the empire only lasted in its entirety until 1294, when it broke into four parts. These parts became politically independent and eventually collapsed one by one.The Ottoman EmpireAfter the Roman Empire had split into two, the Eastern half became known as the Byzantine Empire, and it was based in Constantinople.It lasted until 1453, when Constantinople was conquered by Mehmed the Conqueror, the descendant of Osman I, the first Ottoman Emperor who established the Empire in 1301. His dynasty led the emperor from Istanbul (the new name for Constantinople) for over six centuries.This spread over three continents and is remarkable for its combination of terrestrial conquest and naval proficiency. Whilst the sultans were Muslim, the empire was highly diverse and without any form of enforced religion.Topkapi Palace was the beautiful home of the Ottoman Emperor.The Qing DynastyStarting life in Manchuria, northern China, in the seventeenth century, the Qing Dynasty was one of the longest surviving of Chinese dynasties and the largest empire in Chinese history.It succeeded to form the borders of modern China and to unify Manchus, Mongols, and Han Chinese under the same ruler. It wasn’t until the nineteenth century that p roblems started, with the rise of Christianity in China and the outbreak of revolt and revolution throughout the century.Part of the cause of the decline of the Qing was its failure to modernise in the face of incredibly technologically advanced powers. This meant that when war came, it didn’t stand a chance.The Russian EmpireThe Russian Empire was only one incarnation of the Russian kingdom, which began in 1547 as the Tsardom of Russia. In 1721, under the rule of Peter the Great, however, it changed its name to Imperial Russia â€" and became something of a world power. At its peak â€" through the reigns of Peter and Catherine the Great â€" the Russian Empire was vast, having extended its territory across three continents: Europe, Asia, and North America, where it owned Alaska. It was so large in fact that it is considered one of the three largest empires after the British and the Mongolian.The Russian Empire entered into a period of decline when rebellion and assassination threat ened the stability of the throne. The monarchy was overthrown in 1917 by the Bolshevik Revolution, which turned the Empire into a republic â€" a state with an elected head.The British Empire ruled nearly a quarter of the planet.The British EmpireIt is not an exaggeration to say that the British Empire shaped the modern world, as the extent of its colonies was enormous. Following exploration by the Spanish and Portuguese in the Americas, Britain â€" at that point England and Scotland separately â€" began to accumulate colonial assets across the world.At its peak in the nineteenth century, the British Empire had a colonial presence on every continent on the planet â€" from Australia to the Caribbean, with the entirety of India and parts of Africa in between. Twenty-three percent of the world’s population was at that point under British rule.It fell due to the eventual weakness of Britain and due to the calls for independence and autonomy from colonial societies across the globe.

Equivalent Ratios Online Tutoring - Maths Tutors

Equivalent Ratios Online Tutoring - Maths Tutors Equivalent ratios are basically defined as the two equivalent ratios. For example, a/b and c/d are said to be equivalent ratio if and only if a/b = c/d. This is really advantageous in finding out the value of one unknown variable when the ratios are equivalent and other parameters are also given. This type of ratio generally use cross multiplication concept to evaluate the unknown variable. This can be better clarified by taking the suitable examples and the examples are as follows:- Question 1:- If the following relation holds: (x+8) /20 = 400/20 then evaluate the value of x. Solution 1:- Given (x+8)/20 = 400/20 Step 1:- First let us solve Right hand side (x+8)/20 = 20 Step 2:- Now solving the above expression by cross multiplication, (x+8) = 20 *20 (x+8) = 400 Step 3:- To evaluate the value of x, subtract 8 from both sides, (x+8-8) = 400 -8 So the value of x = 392 Question 2:- If (2x-4)/4 = (x+4)/16 Solution 2:- Given expression is:- (2x-4)/4 = (x+4)/16 Step 1:- In this problem, to evaluate the value of x, we need to cross multiply first. So 16 (2x-4) = 4 (x+4) On solving, 32x -64 = 4x + 16 32x -4x = 64 + 16 28 x = 80 Step 2:- Now to evaluate the value of x, we need to divide both sides by 28 Therefore 28x/28 = 80/28 So x = 80/28 On dividing, We get x = 2.86 as the final answer.

Online Ratios and Rates Tutors

Online Ratios and Rates Tutors Rates ratio is one of the very useful concept in Math. The rate is defined as the ratio between two different quantities. Ratio is the quantitative comparison between the given quantities. Therefore the rate ratio is where two different quantities are compared. Some examples for the rate ratio are centimeter per minute written as cm/min; kilometers per second written as km/sec. Example 1: A vehicle A can cover a distance of 50 miles in 2 hours. Another vehicle B covers 45 miles in 3 hours. Find who travels faster. A travels with the speed (distance per time ratio i.e. miles travelled per hour) = 50 miles/ 2 hours = 25 miles/ hours. B travels with the speed (distance per time ratio i.e. miles travelled per hour) = 45 miles/ 3 hours = 15 miles/ hours. Comparing the speeds, miles / hour ratio for A and B i.e. 25 miles / hour and 15 miles / hours gives A has greater speed. Hence A has greater speed = 25 miles/hour. Example 2: Jack can cycle a distance of 18 miles in 3 hours. John can covers 28 miles in 4 hours by cycling. Find who travels faster. Jack travels with the speed (distance per time ratio i.e. miles travelled per hour) = 18 miles/ 3 hours = 6 miles/ hours. John travels with the speed (distance per time ratio i.e. miles travelled per hour) = 28 miles/ 4 hours = 7 miles/ hours. Comparing the cycling speeds for Jack and John. Hence John has greater speed = 7 miles/hour.
