An empire is a geographically extensive group of diverse states and peoples (ethnic groups) united and ruled by a central authority, either by a monarch (emperor, empress) or an oligarchy. The term empire is derived from the Latin term imperium (a rule, a command; authority, control, power; supreme power, sole dominion; military authority; a dominion, realm), the 'ruling’ of territories that are far beyond the homeland.1
Aside from the more formal usage, the term "empire" can also be used to refer to a large-scale business enterprise (e.g. a transnational corporation), a political organisation controlled by a single individual (a political boss) or a group (political bosses).2 The term empire is associated with other words such as imperialism, colonialism, and globalization. Empire is often used to describe a displeasure to overpowering situations.1 The effects of imperialism exist throughout the world today.
An imperial political structure can be established and maintained in two ways: (i) as a territorial empire of direct conquest and control with force or (ii) as a coercive, hegemonic empire of indirect conquest and control with power. The former method provides greater tribute and direct political control, yet limits further expansion because it absorbs military forces to fixed garrisons. The latter method provides less tribute and indirect control, but avails military forces for further expansion.3 Territorial empires (e.g., the Mongol Empire and Median Empire) tend to be contiguous areas. The term, on occasion, has been applied to maritime empires or thalassocracies, (e.g., the Athenian and British empires) with looser structures and more scattered territories. Empires are usually larger than kingdoms.
This aspiration to universality resulted in conquest by converting ‘outsiders’ or ‘inferiors’ into the colonialized religion. This association of nationality and race became complex and has had a more intense drive for expansion.4

An empire is a multi-ethnic or multinational state with political and/or military dominion of populations who are culturally and ethnically distinct from the imperial (ruling) ethnic group and its culture.5 This is in contrast to a federation, which is an extensive state voluntarily composed of autonomous states and peoples. An empire is a large political party who rules over territories outside of its original borders.
Definitions of what physically and politically constitute an empire vary. It might be a state affecting imperial policies or a particular political structure. Empires are typically formed from diverse ethnic, national, cultural, and religious components.6 Empire and colonialism are used to refer to relationships between powerful state or society versus a less powerful one.
extend relations of power across territorial spaces over which they have no prior or given legal sovereignty, and where, in one or more of the domains of economics, politics, and culture, they gain some measure of extensive hegemony over those spaces for the purpose of extracting or accruing value.7
Sometimes, an empire is a semantic construction, such as when a ruler assumes the title of "emperor". That ruler's nation logically becomes an "empire", despite having no additional territory or hegemony. Examples of this form of empire are the Central African Empire, or the Korean Empire proclaimed in 1897 when Korea, far from gaining new territory, was on the verge of being annexed by the Empire of Japan, the last to use the name officially. Among the last of the empires in the 20th century were the Central African Empire, Ethiopia, Vietnam, Manchukuo, the German Empire, and Korea.
The terrestrial empire's maritime analogue is the thalassocracy, an empire composed of islands and coasts which are accessible to its terrestrial homeland, such as the Athenian-dominated Delian League.
Furthermore, empires can expand by both land and sea. Stephen Howe notes that empires by land can be characterized by expansion over terrain, “extending directly outwards from the original frontier” 8 while an empire by sea can be characterized by colonial expansion and empire building “by an increasingly powerful navy”.9
Empires originated as different types of states, although they commonly began as powerful monarchies. Ideas about empires changed throughout century varying from approval from the public to becoming universally distasteful. Empires are built out of separate units with some kind of diversity – ethnic, national, cultural, religious – and imply at least some inequality between the rulers and the ruled. Without this inequality, the system would be seen as commonwealth.
Many empires were the result of military conquest, incorporating the vanquished states into a political union, but imperial hegemony can be established in other ways. The Athenian Empire, the Roman Empire, and the British Empire developed at least in part under elective auspices. The Empire of Brazil declared itself an empire after separating from the Portuguese Empire in 1822. France has twice transitioned from being called the French Republic to being called the French Empire, while France remained an overseas empire.
Weaker states may seek annexation into the empire. An example is the bequest of Pergamon to the Roman Empire by Attalus III. The Unification of Germany as the empire accreted to the Prussian metropole was less a military conquest of the German states than their political divorce from the Austrian Empire. Having convinced the other states of its military prowess, and having excluded the Austrians, Prussia dictated the terms of imperial membership.
Politically, it was typical for either a monarchy or an oligarchy, rooted in the original core territory of the empire, to continue to dominate. If governmental authority was maintained by controlling water supplies, vital to colonial subjects, such régimes were called hydraulic empires.
Europeans began applying the designation of "empire" to non-European monarchies, such as the Qing dynasty and the Mughal Empire, as well as the Maratha Empire, eventually leading to the looser denotations applicable to any political structure meeting the criteria of "imperium".
Some empires styled themselves as having greater size, scope, and power than the territorial, politico-military, and economic facts support. As a consequence, some monarchs assumed the title of "emperor" (or its corresponding translation, tsar, empereur, kaiser, etc.) and renamed their states as "The Empire of ...."
Empires were seen as an expanding power, administration, ideas and beliefs followed by cultural habits from place to place. Empires tend to impose their culture on the subject states to strengthen the imperial structure. This can have notable effects that outlast the empire itself, both positive and negative.
The Akkadian Empire, established by Sargon the Great (24th century BC), was an early large empire. In the 15th century BC, the New Kingdom of Ancient Egypt, ruled by Thutmose III, was ancient Africa's major force upon incorporating Nubia and the ancient city-states of the Levant. The first empire comparable to Rome in organization was the Neo-Assyrian Empire (916–612 BC). The Median Empire was the first empire within the territory of Persia. By the 6th century BC, after having allied with the Babylonians to defeat the Neo-Assyrian Empire, the Medes were able to establish their own empire, which was the largest of its day and lasted for about sixty years. The successful, and extensive, Achaemenid Empire (550–330 BC), also known as the first Persian Empire, covered Mesopotamia, Egypt, parts of Greece, Thrace, the Middle East, much of Central Asia, and Pakistan, until it was overthrown and replaced by the short-lived empire of Alexander the Great.
The Maurya Empire was a geographically extensive and powerful empire in ancient India, ruled by the Mauryan dynasty from 321–185 BC. The empire was founded in 322 BC by Chandragupta Maurya, who rapidly expanded his power westward across central and western India, taking advantage of the disruptions of local powers following the withdrawal by Alexander the Great. By 320 BC, the Maurya Empire had fully occupied northwestern India as well as defeating and conquering the satraps left by Alexander. It has been estimated that the Maurya dynasty controlled an unprecedented one-third of the world's entire economy, was home to one-third of the world's population at the time (an estimated 50 million out of 150 million humans), contained the world's largest city of the time (Pataliputra, estimated to be larger than Rome under Emperor Trajan) and according to Megasthenes, the empire wielded a military of 600,000 infantry, 30,000 cavalry, and 9,000 war elephants.
In western Asia, the term "Persian Empire" denotes the Iranian imperial states established at different historical periods of pre–Islamic and post–Islamic Persia. In East Asia, various Celestial empires arose periodically between periods of war, civil war, and foreign conquests. In India, Chandragupta expanded the Mauryan Empire to Northwest India (modern day Pakistan and Afghanistan). This also included the era of the spread of Buddhism under Ashoka the Great. In China, the Han Empire, one of East Asia's most long-lived dynasties, was preceded by the short-lived Qin Empire. The Kingdom of Macedonia, under Alexander the Great, became an empire that spanned from Greece to Northwestern India. After Alexander's death, his empire separated into four discrete kingdoms ruled by the Diadochi, which, despite being independent, are called the "Hellenistic Empire" by virtue of their similarities in culture and administration. These successor empires were ultimately absorbed into the Roman Empire.
The Romans were the first nation to invent and embody the concept of empire in their two mandates: to wage war and to make and execute laws.10 They were the most extensive Western empire until the early modern period, and left a lasting impact on Western Europe. Many languages, cultural values, religious institutions, political divisions, urban centers, and legal systems can trace their origins to the Roman Empire. The Roman Empire governed and rested on exploitative actions. They took slaves and money from the peripheries to support the imperial center.10 However, the absolute reliance on conquered peoples to carry out the empire's fortune, sustain wealth, and fight wars would ultimately lead to the collapse of the Roman Empire.10 The Romans were strong believers in what they called their "civilizing mission". This term was legitimized and justified by writers like Cicero who wrote that only under Roman rule could the world flourish and prosper.10 This ideology, that was envisioned to bring a new world order, was eventually spread across the Mediterranean world and beyond. People started to build houses like Romans, eat the same food, wear the same clothes and engage in the same cruel games.10 Even rights of citizenship and authority to rule were granted to people not of Roman or Italian birth.10 This authority given to people outside of Roman culture is an example of how its empire collapsed, with a strong dependence on "foreign" rulers.
The Latin word imperium, referring to a magistrate's power to command, gradually assumed the meaning "The territory in which a magistrate can effectively enforce his commands", while the term "imperator" was originally an honorific meaning "commander". The title was given to generals who were victorious in battle. Thus, an "empire" may include regions that are not legally within the territory of a state, but are under either direct or indirect control of that state, such as a colony, client state, or protectorate. Although historians use the terms "Republican Period" and "Imperial Period" to identify the periods of Roman history before and after absolute power was assumed by Augustus, the Romans themselves continued to refer to their government as a republic, and during the Republican Period, the territories controlled by the republic were referred to as "Imperium Romanum". The emperor's actual legal power derived from holding the office of "consul", but he was traditionally honored with the titles of imperator (commander) and princeps (first man or, chief). Later, these terms came to have legal significance in their own right; an army calling their general "imperator" was a direct challenge to the authority of the current emperor.11
The legal systems of France and its former colonies are strongly influenced by Roman law.12 Similarly, the United States was founded on a model inspired by the Roman Republic, with upper and lower legislative assemblies, and executive power vested in a single individual, the president. The president, as "commander-in-chief" of the armed forces, reflects the ancient Roman titles imperator princeps.13 The Roman Catholic Church, founded in the early Imperial Period, spread across Europe, first by the activities of Christian evangelists, and later by official imperial promulgation.
The 7th century saw the emergence of the Islamic Empire, also referred to as the Arab Empire. The Rashidun Caliphate expanded from the Arabian Peninsula and swiftly conquered the Persian Empire and much of the Byzantine Roman Empire. Its successor state, the Umayyad Caliphate, expanded across North Africa and into the Iberian Peninsula. By the beginning of the 8th century, the Umayyad Caliphate had become the largest empire in history, it would not be surpassed in size until the establishment of the Mongol Empire in the 13th century. In the 7th century, Maritime Southeast Asia witnessed the rise of a Buddhist thallasocracy, the Srivijaya Empire, which thrived for 600 years and was succeeded by the Hindu-Buddhist Majapahit Empire that ruled from the 13th to 15th centuries. In the Southeast Asian mainland, the Hindu-Buddhist Khmer Empire was centered in the city of Angkor and flourished from the 9th to 13th centuries. Following the demise of the Khmer Empire, the Siamese Empire flourished alongside the Burmese and Lan Chang Empires from the 13th through the 18th centuries. In Eastern Europe, during the year of 917, the Byzantine Empire was forced to recognize the Imperial title of Bulgarian rulers (who were called Tsars). The Bulgarian Empire remained a major power in the Balkans until its fall in the late 14th century.
At the time, in the Medieval West, the title "empire" had a specific technical meaning that was exclusively applied to states that considered themselves the heirs and successors of the Roman Empire. Among these were the Byzantine Empire, which was the actual continuation of the Eastern Roman Empire, the Carolingian Empire, the largely Germanic Holy Roman Empire, and the Russian Empire. Yet, these states did not always fit the geographic, political, or military profiles of empires in the modern sense of the word. To legitimise their imperium, these states directly claimed the title of Empire from Rome. The sacrum Romanum imperium (Holy Roman Empire), which lasted from 800 to 1806, claimed to have exclusively comprehended Christian principalities, and was only nominally a discrete imperial state. The Holy Roman Empire was not always centrally-governed, as it had neither core nor peripheral territories, and was not governed by a central, politico-military elite. Hence, Voltaire's remark that the Holy Roman Empire "was neither holy, nor Roman, nor an empire" is accurate to the degree that it ignores14 German rule over Italian, French, Provençal, Polish, Flemish, Dutch, and Bohemian populations, and the efforts of the ninth-century Holy Roman Emperors (i.e., the Ottonians) to establish central control. Voltaire's "... nor an empire" observation applies to its late period.
In 1204, after the Fourth Crusade conquered Constantinople, the crusaders established a Latin Empire (1204–1261) in that city, while the defeated Byzantine Empire's descendants established two smaller, short-lived empires in Asia Minor: the Empire of Nicaea (1204–1261) and the Empire of Trebizond (1204–1461). Constantinople was retaken in 1261 by the Byzantine successor state centered in Nicaea, re-establishing the Byzantine Empire until 1453, by which time the Turkish-Muslim Ottoman Empire (ca. 1300–1918), had conquered most of the region. The Ottoman Empire was a successor of the Abbasid Empire and it was the most powerful empire to succeed the Abbasi empires at the time, as well as one of the most powerful empires in the world.15 The Ottoman Empire centered on modern day Turkey, dominated the eastern Mediterranean, overthrew the Byzantine Empire to claim Constantinople and it would start battering at Austria and Malta, which were countries that were key to central and to south-west Europe respectivelymainly for their geographical location.15 The reason these occurrences of batterings were so important was because the Ottomans were Muslim and the rest of Europe was Christian so there was a sense of religious fighting going on.16 This was not just a rivalry of East and West but a rivalry between Christians and Muslims.17 Both the Christians and Muslims had alliances with other countries and they had problems in them as well.18 The flows of trade and of cultural influences across the supposed great divide never ceased so the countries never stopped bartering with each other.19 These epochal clashes between civilizations profoundly shaped many people's thinking back then and continues to do so in the present day.20 Modern hatred against Muslim communities in South-Eastern Europe, mainly in Bosnia and Kosovo, has often been articulated in terms of seeing them as unwelcome residues of this imperialism: in short, as Turks.21 Moreover, Eastern Orthodox imperialism was not re-established until the coronation of Peter the Great as Emperor of Russia in 1721. Likewise, with the collapse of the Holy Roman Empire in 1806 during the Napoleonic Wars (1803–1815), the Austrian Empire (1804–1867) emerged reconstituted as the Empire of Austria–Hungary (1867–1918), having "inherited" the imperium of Central and Western Europe from the losers of said wars.
In the thirteenth century, Genghis Khan expanded the Mongol Empire to be the largest contiguous empire in the world. Genghis Khan's grandson, Kublai Khan, was proclaimed emperor, and established his imperial capital at Beijing. However, during his reign, the empire separated into four discrete khanates. Nevertheless, the emergence of the Pax Mongolica had significantly eased trade and commerce across Asia.2223
In the 15th century, European landings in the so-called "New World" (first, the Americas, and later Australia), along with Portuguese travels around the Cape of Good Hope and along the coast of Africa bordering the southeast Indian Ocean, proved ripe opportunities for the continent's Renaissance-era monarchies to establish colonial empires like those of the ancient Romans and Greeks. In the Old World, colonial imperialism was attempted and established on the Canary Islands and Ireland. These conquered lands and people became de jure subordinates of the empire, rather than de facto imperial territories and subjects. Such subjugation often elicited "client-state" resentment that the empire unwisely ignored, leading to the collapse of the European colonial imperial system in the late 19th century and the early and mid-20th century. Spanish discovery of the New World gave way to many expeditions led by England, Portugal, France, the Dutch Republic, and Spain. In the 18th century, the Spanish Empire was at its height because of the great mass of goods taken from conquered territory in the Americas (Mexico, parts of the United States, the Caribbean, most of Central America, and South America) and the Philippines.
The French emperors Napoleon I and Napoleon III (See: Premier Empire, Second French Empire, and French colonial empire) each attempted establishing a western imperial hegemony centered in France. The German Empire (1871–1918), another "heir to the Holy Roman Empire", arose in 1871.
The Ashanti Empire (or Confederacy), also Asanteman (1701–1896), was a West African state of the Ashanti, the Akan people of the Ashanti Region, Akanland in modern day Ghana. The Ashanti (or Asante) were a powerful, militaristic and highly disciplined people in West Africa. Their military power, which came from effective strategy and an early adoption of European firearms, created an empire that stretched from central Akanland (in modern-day Ghana) to present day Benin and Côte d'Ivoire, bordered by the Dagomba kingdom to the north and Dahomey to the east. Due to the empire's military prowess, sophisticated hierarchy, social stratification and culture, the Ashanti empire had one of the largest historiographies of any indigenous Sub-Saharan African political entity.
The Sikh Empire (1799–1846) was established in the Punjab region of India. The empire collapsed when its founder, Ranjit Singh, died and its army fell to the British. During the same period, the Maratha Empire (also known as the Maratha Confederacy) was a Hindu state located in present-day India. It existed from 1674 to 1818, and at its peak, the empire's territories covered much of Southern Asia. The empire was founded and consolidated by Shivaji. After the death of Mughal Emperor Aurangzeb, it expanded greatly under the rule of the Peshwas. In 1761, the Maratha army lost the Third Battle of Panipat, which halted the expansion of the empire. Later, the empire was divided into a confederacy of states which, in 1818, were lost to the British during the Anglo-Maratha wars.25
The British established their first empire (1583–1783) in North America by colonising lands that made up British America, including parts of Canada and the Thirteen Colonies. In 1776, the Continental Congress of the Thirteen Colonies declared itself independent from the British Empire, thus beginning the American Revolution. Britain turned towards Asia, the Pacific, and later Africa, with subsequent exploration leading to the rise of the Second British Empire (1783–1815), which was followed by the Industrial Revolution and Britain's Imperial Century (1815–1914).26
In time, an empire may change from one political entity to another. To wit, the Holy Roman Empire, a German re-constitution of the Roman Empire, metamorphosed into various political structures (i.e., federalism), and eventually, under Habsburg rule, re-constituted itself as the Austrian Empire, an empire of much different politics and vaster extension.
An autocratic empire can become a republic (e.g., the Central African Empire in 1979), or it can become a republic with its imperial dominions reduced to a core territory (e.g., Weimar Germany (1918–1919) and the Ottoman Empire (1918–1923)). The dissolution of the Austro–Hungarian Empire after 1918 is an example of a multi-ethnic superstate broken into its constituent states: the republics, kingdoms, and provinces of Austria, Hungary, Transylvania, Croatia, Slovenia, Bosnia and Herzegovina, Czechoslovakia, Ruthenia, Galicia, et al.
After the Second World War (1939–1945), the process became commonly known as decolonisation. The British Empire evolved into a loose, multinational Commonwealth of Nations, while the French colonial empire metamorphosed to a Francophone commonwealth. The French territory of Kwang-Chou-Wan was given back to China in 1946. The British gave Hong Kong back to China in 1997 after 150 years of rule. The Portuguese territory of Macau was given back to China in 1999. Macau and Hong Kong were not incorporated into the provincial structure of China; they have an autonomous system of government as Special Administrative Regions of the People's Republic of China.
France still governs colonies (French Guyana, Martinique, Réunion, French Polynesia, New Caledonia, St Martin, Saint-Pierre-et-Miquelon, Guadeloupe, TAAF, Wallis and Futuna, Saint Barthélemy, and Mayotte) and exerts hegemony in Francophone Africa (29 francophone countries such as Chad, Rwanda, et cetera). Fourteen British Overseas Territories remain under British sovereignty. Sixteen countries of the Commonwealth of Nations share their head of state, Queen Elizabeth II, as Commonwealth realms.
While the notion of "formal empire" may have ended, it is important to note that many of these former colonial populations still continue to face the historical legacy of colonialism. While traditional sovereignty has been granted to these political units, one must not forget the economic, political and cultural entanglements that continue to affect these subject populations. Therefore, discursive practices of Empire are still present in countries today.
Contemporaneously, the concept of empire is politically valid, yet is not always used in the traditional sense. For example, Japan is considered the world's sole remaining empire because of the continued presence of the Japanese Emperor in national politics. Despite the semantic reference to imperial power, Japan is a de jure constitutional monarchy, with a homogeneous population of 127 million people that is 98.5 percent ethnic Japanese, making it one of the largest nation-states.27
Characterizing some aspects of American foreign policy and international behavior as "American Empire" is controversial but not uncommon. Stuart Creighton Miller posits that the public's sense of innocence about Realpolitik (cf. American Exceptionalism) impairs popular recognition of US imperial conduct since it governed other countries via surrogates. These surrogates were domestically-weak, right-wing governments that would collapse without US support.28 Former President G.W. Bush's Secretary of Defense, Donald Rumsfeld, said: "We don't seek empires. We're not imperialistic; we never have been."29 This statement directly contradicts Thomas Jefferson who, in the 1780s while awaiting the fall of the Spanish empire, said: "...till our population can be sufficiently advanced to gain it from them piece by piece".303132 In turn, historian Sidney Lens argues that from its inception, the US has used every means available to dominate other nations.33
Since the European Union began in 1993 as a west European trade bloc, it has established its own currency, the Euro (1999), established discrete military forces, and exercised its limited hegemony in parts of eastern Europe and Asia. The political scientist Jan Zielonka suggests that this behaviour is imperial because it coerces its neighbouring countries into adopting its European economic, legal, and political structures.343536373839
In his book review of Empire (2000) by Michael Hardt and Antonio Negri, Mehmet Akif Okur posits that since the 11 September 2001 terrorist attacks in the US, the international relations determining the world's balance of power (political, economic, military) have been altered. These alterations include the intellectual (political science) trends that perceive the contemporary world's order via the re-territorrialisation of political space, the re-emergence of classical imperialist practices (the "inside" vs. "outside" duality, cf. the Other), the deliberate weakening of international organisations, the restructured international economy, economic nationalism, the expanded arming of most countries, the proliferation of nuclear weapon capabilities and the politics of identity emphasizing a state's subjective perception of its place in the world, as a nation and as a civilisation. These changes constitute the "Age of Nation Empires"; as imperial usage, nation-empire denotes the return of geopolitical power from global power blocs to regional power blocs (i.e., centred upon a "regional power" state [China, Russia, U.S., et al.]) and regional multi-state power alliances (i.e., Europe, Latin America, South East Asia). Nation-empire regionalism claims sovereignty over their respective (regional) political (social, economic, ideologic), cultural, and military spheres.40
