Empire

[33] Stephen Howe writes that with the exception of the Roman, Chinese and "perhaps ancient Egyptian states", early empires seldom survived the death of their founder and were usually limited in scope to conquest and collection of tribute, having little impact on the everyday lives of their subjects.

[48] 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.

Through a strong centralized administration and an aggressive military stance towards invaders, the Ajuran Sultanate successfully resisted an Oromo invasion from the west and a Portuguese incursion from the east during the Gaal Madow and the Ajuran-Portuguese wars.

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 Ivory Coast, bordered by the Dagomba kingdom to the north and Dahomey to the east.

The extensive overseas expansion, particularly in the South Asia and Americas by the Portuguese and Spanish, later joined by the English, French and Dutch, created empires on which the Sun never sets.

[92] The impacts of this period are still prominent in the current age "including widespread use of the English language, belief in Protestant religion, economic globalization, modern precepts of law and order, and representative democracy.

Though the American Revolutionary War (1775–1783) and the collapse of the Spanish Empire in Latin America in the 1820s ended the first era of European colonialism, the period featured an unprecedented pursuit of overseas territorial acquisitions.

[103] Correspondingly, the thesis continues,[104] when the space for expansion ended, the empires became destined for head-on collisions, as reflected in the anxious, claustrophobic mood of the Fin de siècle.

The time that now followed lay in the chests of men like a heavy nightmare... And then the first mighty lightening flash struck the earth ... and with the thunder of heaven there mingled the roar of World War batteries...

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.

The dissolution of the Austro-Hungarian Empire after 1918 provides an example of a multi-ethnic superstate broken into constituent nation-oriented states: the republics, kingdoms, and provinces of Austria, Hungary, Transylvania, Croatia, Slovenia, Bosnia and Herzegovina, Czechoslovakia, Ruthenia, Galicia, et al.

[122] Stuart Creighton Miller posits that the public's sense of innocence about Realpolitik (politics based on practical considerations, rather than ideals) impacts popular recognition of US imperial conduct since it governed other countries via surrogates.

[149]Similarly, Anthony Pagden, Eliot A. Cohen, Jane Burbank and Frederick Cooper estimate that "empires have always been more frequent, more extensive political and social forms than tribal territories or nations have ever been.

The endurance of empire challenges the notion that the nation-state is natural, necessary, and inevitable ...[152]Political scientist Hedley Bull wrote that "in the broad sweep of human history ... the form of states system has been the exception rather than the rule".

[158]German Sociologist Friedrich Tenbruck finds that the macro-historic process of imperial expansion gave rise to global history in which the formations of universal empires were most significant stages.

[163]Fichte's later compatriot, Geographer Alexander von Humboldt, in the mid-Nineteenth century observed a macro-historic trend of imperial growth in both Hemispheres: "Men of great and strong minds, as well as whole nations, acted under influence of one idea, the purity of which was utterly unknown to them.

Writing during the First, Oswald Spengler in The Decline of the West compared two emergences of universal empires and implied for the modern world: The Chinese League of States failed as well as the Taoist idea of intellectual self-disarmament.

[175] Writing during the next World War, political scientists Derwent Whittlesey, Robert Strausz-Hupé and John H. Herz concluded: "Now that the earth is at last parceled out, consolidation has commenced.

[178]Writing in the last year of the War, American theologian Parley Paul Wormer, German historian Ludwig Dehio, and Hungarian-born writer Emery Reves drew similar conclusions.

[181] Reves added "Postscript" to the Anatomy, opening: "A few weeks after the publication of this book, the first atomic bomb exploded over the city of Hiroshima…" This new physical fact however has changed nothing in the political situation.

[192] Section VIII, "Atomic Armaments", of the famous National Security Council Report 68 (NSC 68), approved by President Harry Truman in 1951, uses the term "blow" 17 times, mostly preceded by such adjectives as "powerful", "overwhelming", or "crippling".

"[214] Hans Morgenthau wrote that the very imperial expansion into relatively empty geographical spaces in the Eighteenth and Nineteenth centuries, in Africa, Eurasia, and western North America, deflected great power politics into the periphery of the earth, thereby reducing conflict.

The unexplored and unclaimed "blank" spaces on the world map were rapidly diminishing ... and the sense of "global closure" prompted an anxious fin-de-siècle debate about the future of the great empires ...

[235]Walter Russell Mead observes that the United States attempts to recreate "globally" what the ancient empires of Egypt, China and Rome had each accomplished on a regional basis.

"[213] The "Father of American Anthropology," Franz Boas, known for his historical particularism and cultural relativism, outlined the "inexorable laws of history" by which political units grow larger in size and smaller in number.

"[243] Seven later scholars—Hornell Hart,[244] Raoul Naroll,[245] Louis Morano,[246] Rein Taagepera,[247] the author of the circumscription theory Robert Carneiro[248][249] and Jesse H. Ausubel & Cesare Marchetti[250]—researched expanding imperial cycles.

"[251] The founder of the Paneuropean Union, Richard von Coudenhove-Kalergi, writing yet in 1943, drew a more specific and immediate future imperial project: After the War America is bound "to take over the command of the skies."

Consequently, as President Dwight Eisenhower put it, the NATO allies became "almost psychopathic" whenever anyone talked about a US withdrawal, and the reception of his successor John F. Kennedy in Berlin was "almost hysterical," as Chancellor Konrad Adenauer characterized it.

Two years later, he wrote: When it was decided to deploy US divisions to Europe, no one had "for an instant" thought that they would remain there for "several decades"—that the United States could "build a sort of Roman Wall with its own troops and so protect the world.

Both "were good auguries for the prospect that, in a post-Modern chapter of Western history, a supranational commonwealth originally based on the hegemony of a paramount power over its satellites might eventually be put on the sounder basis of a constitutional partnership in which all the people of all the partner states would have their fare share in the conduct of common affairs.
