The Roman emperor was the ruler of the Roman Empire during the imperial period. The emperors used a variety of different titles throughout history; when a given Roman is described as becoming "emperor" in English, it reflects his taking of the title Augustus or Caesar. Another title used was imperator a military honorific. Early Emperors used the title princeps. Emperors amassed republican titles, notably princeps senatus and pontifex maximus; the legitimacy of an emperor's rule depended on his control of the army and recognition by the Senate. The first emperors reigned alone; the Romans considered the office of emperor to be distinct from that of a king. The first emperor, resolutely refused recognition as a monarch. Although Augustus could claim that his power was authentically republican, his successor, could not convincingly make the same claim. Nonetheless, for the first three hundred years of Roman emperors, from Augustus until Diocletian, efforts were made to portray the emperors as leaders of a republic.
From Diocletian, whose tetrarchic reforms divided the position into one emperor in the West and one in the East, until the end of the Empire, emperors ruled in an monarchic style and did not preserve the nominal principle of a republic, but the contrast with "kings" was maintained: although the imperial succession was hereditary, it was only hereditary if there was a suitable candidate acceptable to the army and the bureaucracy, so the principle of automatic inheritance was not adopted. Elements of the republican institutional framework were preserved after the end of the Western Empire; the Western Roman Empire collapsed in the late 5th century after multiple invasions of imperial territory by Germanic barbarian tribes. Romulus Augustulus is considered to be the last emperor of the West after his forced abdication in 476, although Julius Nepos maintained a claim recognized by the Eastern Empire to the title until his death in 480. Following Nepos' death, the Eastern Emperor Zeno abolished the division of the position and proclaimed himself as the sole Emperor of a reunited Roman Empire.
The Eastern imperial lineage continued to rule from Constantinople. Constantine XI Palaiologos was the last Roman emperor in Constantinople, dying in the Fall of Constantinople to the Ottomans in 1453; the "Byzantine" emperors from Heraclius in 629 and onwards adopted the title of basileus, which had meant king in Greek but became a title reserved for the Roman emperor and the ruler of the Sasanian Empire. Other kings were referred to as rēgas. In addition to their pontifical office, some emperors were given divine status after death. With the eventual hegemony of Christianity, the emperor came to be seen as God's chosen ruler, as well as a special protector and leader of the Christian Church on Earth, although in practice an emperor's authority on Church matters was subject to challenge. Due to the cultural rupture of the Turkish conquest, most western historians treat Constantine XI as the last meaningful claimant to the title Roman Emperor. From 1453, one of the titles used by the Ottoman Sultans was "Caesar of Rome", part of their titles until the Ottoman Empire ended in 1922.
A Byzantine group of claimant Roman emperors existed in the Empire of Trebizond until its conquest by the Ottomans in 1461, though they had used a modified title since 1282. Eastern emperors in Constantinople had been recognized and accepted as Roman emperors both in the East, which they ruled, by the Papacy and Germanic kingdoms of the West until the deposition of Constantine VI and accession of Irene of Athens as Empress regnant in 797. Objecting to a woman ruling the Roman Empire in her own right and issues with the eastern clergy, the Papacy would create a rival lineage of Roman emperors in western Europe, the Holy Roman Emperors, which ruled the Holy Roman Empire for most of the period between 800 and 1806; these Emperors were never recognized as Roman emperors by the court in Constantinople. Modern historians conventionally regard Augustus as the first Emperor whereas Julius Caesar is considered the last dictator of the Roman Republic, a view having its origins in the Roman writers Plutarch and Cassius Dio.
However, the majority of Roman writers, including Josephus, Pliny the Younger and Appian, as well as most of the ordinary people of the Empire, thought of Julius Caesar as the first Emperor. At the end of the Roman Republic no new, no single, title indicated the individual who held supreme power. Insofar as emperor could be seen as the English translation of imperator Julius Caesar had been an emperor, like several Roman generals before him. Instead, by the end of the civil wars in which Julius Caesar had led his armies, it became clear that there was no consensus to return to the old-style monarchy, but that the period when several officials, bestowed with equal power by the senate, would fight one another had come to an end. Julius Caesar, Augustus after him, accumulated offices and titles of the highest importance in the Republic, making the power attached to those offices permanent, preventing anyone with similar aspirations from accumulating or maintaining power for themselves. However, Julius Caesar, unlike those after
Tactica of Emperor Leo VI the Wise
The Tactica is a military treatise written by or on behalf of Byzantine Emperor Leo VI the Wise in c. 895–908 and edited by his son, Constantine VII. Drawing on earlier authors such as Aelian and the Strategikon of emperor Maurice, it is one of the major works on Byzantine military tactics, written on the eve of Byzantium's "age of reconquest"; the original Greek title is τῶν ἐν πολέμοις τακτικῶν σύντομος παράδοσις. The Tactica elaborates on a wide variety of issues, such as infantry and cavalry formations, drills and naval warfare etc, it is written in a legislative form of language and comprises 20 Constitutions and an Epilogue and is concluded by 12 additional chapters, the latter focusing on ancient tactics. The text of the Tactica is transmitted in several manuscript prototypes, of which the most authoritative date to within a generation of Leo himself. Leo mentions within the Tactica, that Christianity could adopt Islam's doctrine of a "holy war" for its military applications. An edition with English translation by G. T. Dennis, The Taktika of Leo VI.

Cambridge University Press
Cambridge University Press is the publishing business of the University of Cambridge. Granted letters patent by King Henry VIII in 1534, it is the world's oldest publishing house and the second-largest university press in the world, it holds letters patent as the Queen's Printer. The press mission is "to further the University's mission by disseminating knowledge in the pursuit of education and research at the highest international levels of excellence". Cambridge University Press is a department of the University of Cambridge and is both an academic and educational publisher. With a global sales presence, publishing hubs, offices in more than 40 countries, it publishes over 50,000 titles by authors from over 100 countries, its publishing includes academic journals, reference works and English language teaching and learning publications. Cambridge University Press is a charitable enterprise that transfers part of its annual surplus back to the university. Cambridge University Press is both the oldest publishing house in the world and the oldest university press.
It originated from letters patent granted to the University of Cambridge by Henry VIII in 1534, has been producing books continuously since the first University Press book was printed. Cambridge is one of the two privileged presses. Authors published by Cambridge have included John Milton, William Harvey, Isaac Newton, Bertrand Russell, Stephen Hawking. University printing began in Cambridge when the first practising University Printer, Thomas Thomas, set up a printing house on the site of what became the Senate House lawn – a few yards from where the press's bookshop now stands. In those days, the Stationers' Company in London jealously guarded its monopoly of printing, which explains the delay between the date of the university's letters patent and the printing of the first book. In 1591, Thomas's successor, John Legate, printed the first Cambridge Bible, an octavo edition of the popular Geneva Bible; the London Stationers objected strenuously. The university's response was to point out the provision in its charter to print "all manner of books".
Thus began the press's tradition of publishing the Bible, a tradition that has endured for over four centuries, beginning with the Geneva Bible, continuing with the Authorized Version, the Revised Version, the New English Bible and the Revised English Bible. The restrictions and compromises forced upon Cambridge by the dispute with the London Stationers did not come to an end until the scholar Richard Bentley was given the power to set up a'new-style press' in 1696. In July 1697 the Duke of Somerset made a loan of £200 to the university "towards the printing house and presse" and James Halman, Registrary of the University, lent £100 for the same purpose, it was in Bentley's time, in 1698, that a body of senior scholars was appointed to be responsible to the university for the press's affairs. The Press Syndicate's publishing committee still meets and its role still includes the review and approval of the press's planned output. John Baskerville became University Printer in the mid-eighteenth century.
Baskerville's concern was the production of the finest possible books using his own type-design and printing techniques. Baskerville wrote, "The importance of the work demands all my attention. Caxton would have found nothing to surprise him if he had walked into the press's printing house in the eighteenth century: all the type was still being set by hand. A technological breakthrough was badly needed, it came when Lord Stanhope perfected the making of stereotype plates; this involved making a mould of the whole surface of a page of type and casting plates from that mould. The press was the first to use this technique, in 1805 produced the technically successful and much-reprinted Cambridge Stereotype Bible. By the 1850s the press was using steam-powered machine presses, employing two to three hundred people, occupying several buildings in the Silver Street and Mill Lane area, including the one that the press still occupies, the Pitt Building, built for the press and in honour of William Pitt the Younger.
Under the stewardship of C. J. Clay, University Printer from 1854 to 1882, the press increased the size and scale of its academic and educational publishing operation. An important factor in this increase was the inauguration of its list of schoolbooks. During Clay's administration, the press undertook a sizeable co-publishing venture with Oxford: the Revised Version of the Bible, begun in 1870 and completed in 1885, it was in this period as well that the Syndics of the press turned down what became the Oxford English Dictionary—a proposal for, brought to Cambridge by James Murray before he turned to Oxford. The appointment of R. T. Wright as Secretary of the Press Syndicate in 1892 marked the beginning of the press's development as a modern publishing business with a defined editorial policy and administrative structure, it was Wright who devised the plan for one of the most distinctive Cambridge contributions to publishing—the Cambridge Histories. The Cambridge Modern History was published
War is a state of armed conflict between states, governments and informal paramilitary groups, such as mercenaries and militias. It is characterized by extreme violence, aggression and mortality, using regular or irregular military forces. Warfare refers of wars in general. Total war is warfare, not restricted to purely legitimate military targets, can result in massive civilian or other non-combatant suffering and casualties; the scholarly study of war is sometimes called polemology, from the Greek polemos, meaning "war", -logy, meaning "the study of". While some scholars see war as a universal and ancestral aspect of human nature, others argue it is a result of specific socio-cultural or ecological circumstances; the English word war derives from the 11th century Old English words wyrre and werre, from Old French werre, in turn from the Frankish *werra deriving from the Proto-Germanic *werzō'mixture, confusion'. The word is related to the Old Saxon werran, Old High German werran, the German verwirren, meaning “to confuse”, “to perplex”, “to bring into confusion”.
War must entail some degree of confrontation using weapons and other military technology and equipment by armed forces employing military tactics and operational art within a broad military strategy subject to military logistics. Studies of war by military theorists throughout military history have sought to identify the philosophy of war, to reduce it to a military science. Modern military science considers several factors before a national defence policy is created to allow a war to commence: the environment in the area of combat operations, the posture national forces will adopt on the commencement of a war, the type of warfare troops will be engaged in. Asymmetric warfare is a conflict between belligerents of drastically different levels of military capability and/or size. Biological warfare, or germ warfare, is the use of weaponized biological toxins or infectious agents such as bacteria and fungi. Chemical warfare involves the use of weaponized chemicals in combat. Poison gas as a chemical weapon was principally used during World War I, resulted in over a million estimated casualties, including more than 100,000 civilians.
Civil war is a war between forces belonging to political entity. Conventional warfare is declared war between states in which nuclear, biological, or chemical weapons are not used or see limited deployment. Cyberwarfare involves the actions by a nation-state or international organization to attack and attempt to damage another nation's information systems. Insurgency is a rebellion against authority, when those taking part in the rebellion are not recognized as belligerents. An insurgency can be fought via counter-insurgency warfare, may be opposed by measures to protect the population, by political and economic actions of various kinds aimed at undermining the insurgents' claims against the incumbent regime. Information warfare is the application of destructive force on a large scale against information assets and systems, against the computers and networks that support the four critical infrastructures. Nuclear warfare is warfare in which nuclear weapons are the primary, or a major, method of achieving capitulation.
Total war is warfare by any means possible, disregarding the laws of war, placing no limits on legitimate military targets, using weapons and tactics resulting in significant civilian casualties, or demanding a war effort requiring significant sacrifices by the friendly civilian population. Unconventional warfare, the opposite of conventional warfare, is an attempt to achieve military victory through acquiescence, capitulation, or clandestine support for one side of an existing conflict. War of aggression is a war for gain rather than self-defense. War of liberation, Wars of national liberation or national liberation revolutions are conflicts fought by nations to gain independence; the term is used in conjunction with wars against foreign powers to establish separate sovereign states for the rebelling nationality. From a different point of view, these wars are called insurgencies, rebellions, or wars of independence; the earliest recorded evidence of war belongs to the Mesolithic cemetery Site 117, determined to be 14,000 years old.
About forty-five percent of the skeletons there displayed signs of violent death. Since the rise of the state some 5,000 years ago, military activity has occurred over much of the globe; the advent of gunpowder and the acceleration of technological advances led to modern warfare. According to Conway W. Henderson, "One source claims that 14,500 wars have taken place between 3500 BC and the late 20th century, costing 3.5 billion lives, leaving only 300 years of peace." An unfavorable review of this estimate mentions the following regarding one of the proponents of this estimate: "In addition feeling that the war casualties figure was improbably high, he changed "approximately 3,640,000,000 human beings have been killed by war or the diseases produced by war" to "approximately 1,240,000,000 human beings...&c."" The lower figure is more plausible, but could be on the high side, considering that the 100 deadliest acts of mass violence between 480 BCE and 2002 CE claimed about 455 million human lives in total.
Primitive warfare is estimated to have accounted for 15
Macedonia (ancient kingdom)
Macedonia called Macedon, was an ancient kingdom on the periphery of Archaic and Classical Greece, the dominant state of Hellenistic Greece. The kingdom was founded and ruled by the royal Argead dynasty, followed by the Antipatrid and Antigonid dynasties. Home to the ancient Macedonians, the earliest kingdom was centered on the northeastern part of the Greek peninsula, bordered by Epirus to the west, Paeonia to the north, Thrace to the east and Thessaly to the south. Before the 4th century BC, Macedonia was a small kingdom outside of the area dominated by the great city-states of Athens and Thebes, subordinate to Achaemenid Persia. During the reign of the Argead king Philip II, Macedonia subdued mainland Greece and Thrace through conquest and diplomacy. With a reformed army containing phalanxes wielding the sarissa pike, Philip II defeated the old powers of Athens and Thebes in the Battle of Chaeronea in 338 BC. Philip II's son Alexander the Great, leading a federation of Greek states, accomplished his father's objective of commanding the whole of Greece when he destroyed Thebes after the city revolted.
During Alexander's subsequent campaign of conquest, he overthrew the Achaemenid Empire and conquered territory that stretched as far as the Indus River. For a brief period, his empire was the most powerful in the world – the definitive Hellenistic state, inaugurating the transition to a new period of Ancient Greek civilization. Greek arts and literature flourished in the new conquered lands and advances in philosophy and science spread throughout much of the ancient world. Of particular importance were the contributions of Aristotle, tutor to Alexander, whose writings became a keystone of Western philosophy. After Alexander's death in 323 BC, the ensuing wars of the Diadochi, the partitioning of Alexander's short-lived empire, Macedonia remained a Greek cultural and political center in the Mediterranean region along with Ptolemaic Egypt, the Seleucid Empire, the Kingdom of Pergamon. Important cities such as Pella and Amphipolis were involved in power struggles for control of the territory. New cities were founded, such as Thessalonica by the usurper Cassander.
Macedonia's decline began with the Macedonian Wars and the rise of Rome as the leading Mediterranean power. At the end of the Third Macedonian War in 168 BC, the Macedonian monarchy was abolished and replaced by Roman client states. A short-lived revival of the monarchy during the Fourth Macedonian War in 150–148 BC ended with the establishment of the Roman province of Macedonia; the Macedonian kings, who wielded absolute power and commanded state resources such as gold and silver, facilitated mining operations to mint currency, finance their armies and, by the reign of Philip II, a Macedonian navy. Unlike the other diadochi successor states, the imperial cult fostered by Alexander was never adopted in Macedonia, yet Macedonian rulers assumed roles as high priests of the kingdom and leading patrons of domestic and international cults of the Hellenistic religion; the authority of Macedonian kings was theoretically limited by the institution of the army, while a few municipalities within the Macedonian commonwealth enjoyed a high degree of autonomy and had democratic governments with popular assemblies.
The name Macedonia comes from the ethnonym Μακεδόνες, which itself is derived from the ancient Greek adjective μακεδνός, meaning "tall" descriptive of the people. It has the same root as the adjective μακρός, meaning "long" or "tall" in Ancient Greek; the name is believed to have meant either "highlanders", "the tall ones", or "high grown men". Linguist Robert S. P. Beekes claims that both terms are of Pre-Greek substrate origin and cannot be explained in terms of Indo-European morphology; the Classical Greek historians Herodotus and Thucydides reported the legend that the Macedonian kings of the Argead dynasty were descendants of Temenus, king of Argos, could therefore claim the mythical Heracles as one of their ancestors as well as a direct lineage from Zeus, chief god of the Greek pantheon. Contradictory legends state that either Perdiccas I of Macedon or Caranus of Macedon were the founders of the Argead dynasty, with either five or eight kings before Amyntas I; the assertion that the Argeads descended from Temenus was accepted by the Hellanodikai authorities of the Ancient Olympic Games, permitting Alexander I of Macedon to enter the competitions owing to his perceived Greek heritage.
Little is known about the kingdom before the reign of Alexander I's father Amyntas I of Macedon during the Archaic period. The kingdom of Macedonia was situated along the Haliacmon and Axius rivers in Lower Macedonia, north of Mount Olympus. Historian Robert Malcolm Errington suggests that one of the earliest Argead kings established Aigai as their capital in the mid-7th century BC. Before the 4th century BC, the kingdom covered a region corresponding to the western and central parts of the region of Macedonia in modern Greece, it expanded into the region of Upper Macedonia, inhabited by the Greek Lyncestae and Elimiotae tribes, into regions of Emathia, Bottiaea, Mygdonia and Almopia, which were inhabited by various peoples such as Thracians and Phrygians. Macedonia's non-Greek neighbors included Thracians, inhabiting territories to the northeast, Illyrians to the northwest, Paeonians to the north, while the lands of Thessaly to the south and Epirus to the west were inhabited by Greeks with similar cultures to that of the Macedonians.

Military tactics encompasses the art of organising and employing fighting forces on or near the battlefield. They involve the application of four battlefield functions which are related – kinetic or firepower, protection or security, shock action. Tactics are a separate function from control and logistics. In contemporary military science, tactics are the lowest of three levels of warfighting, the higher levels being the strategic and operational levels. Throughout history, there has been a shifting balance between the four tactical functions based on the application of military technology, which has led to one or more of the tactical functions being dominant for a period of time accompanied by the dominance of an associated fighting arm deployed on the battlefield, such as infantry, cavalry or tanks. Beginning with the use of melee and missile weapons such as clubs and spears, the kinetic or firepower function of tactics has developed along with technological advances so that the emphasis has shifted over time from the close-range melee and missile weapons to longer-range projectile weapons.
Kinetic effects were delivered by the sword, spear and bow until the introduction of artillery by the Romans. Until the mid 19th century, the value of infantry-delivered missile firepower was not high, meaning that the result of a given battle was decided by infantry firepower alone relying on artillery to deliver significant kinetic effects; the development of disciplined volley fire, delivered at close range, began to improve the hitting power of infantry, compensated in part for the limited range, poor accuracy and low rate of fire of early muskets. Advances in technology the introduction of the rifled musket, used in the Crimean War and American Civil War, meant flatter trajectories and improved accuracy at greater ranges, along with higher casualties; the resulting increase in defensive firepower meant infantry attacks without artillery support became difficult. Firepower became crucial to fixing an enemy in place to allow a decisive strike. Machine guns added to infantry firepower at the turn of the 20th century, the mobile firepower provided by tanks, self-propelled artillery and military aircraft rose in the century that followed.
Along with infantry weapons and other armoured vehicles, self-propelled artillery, guided weapons and aircraft provide the firepower of modern armies. Mobility, which determines how a fighting force can move, was for most of human history limited by the speed of a soldier on foot when supplies were carried by beasts of burden. With this restriction, most armies could not travel more than 32 kilometres per day, unless travelling on rivers. Only small elements of a force such as cavalry or specially trained light troops could exceed this limit; this restriction on tactical mobility remained until the latter years of World War I when the advent of the tank improved mobility sufficiently to allow decisive tactical manoeuvre. Despite this advance, full tactical mobility was not achieved until World War II when armoured and motorised formations achieved remarkable successes. However, large elements of the armies of World War II remained reliant on horse-drawn transport, which limited tactical mobility within the overall force.
Tactical mobility can be limited by the use of field obstacles created by military engineers. Personal armour has been worn since the classical period to provide a measure of individual protection, extended to include barding of the mount; the limitations of armour have always been weight and bulk, its consequent effects on mobility as well as human and animal endurance. By the 18th and 19th centuries, personal armour had been discarded, until the re-introduction of helmets during World War I in response to the firepower of artillery. Armoured fighting vehicles proliferated during World War II, after that war, body armour returned for the infantry in Western armies. Fortifications, which have been used since ancient times, provide collective protection, modern examples include entrenchments, barbed wire and minefields. Like obstacles, fortifications are created by military engineers. Shock action is as much a psychological function of tactics as a physical one, can be enhanced by the use of surprise.
It has been provided by charging infantry, well as by chariots, war elephants and armoured vehicles which provide momentum to an assault. It has been used in a defensive way, for example by the drenching flights of arrows from English longbowmen at the Battle of Agincourt in 1415 which caused the horses of the French knights to panic. During early modern warfare, the use of the tactical formations of columns and lines had a greater effect than the firepower of the formations alone. During the early stages of World War II, the combined effects of German machine gun and tank gun firepower, enhanced by accurate indirect fire and air attack broke up Allied units before their assault commenced, or caused them to falter due to casualties among key unit leaders. In both the early modern and World War II examples, the cumulative psychological shock effect on the enemy was greater than the actual casualties incurred; the development of tactics has involved a shifting balance between the four tactical functions since ancient times, changes in firepower and mobility have been fundamental to these changes.
Various models have been proposed to explain the interaction between the tactical functions and the dominance of individual fighting arms during different periods. J. F. C. Fuller proposed three "tactical cycles" in each of the classical and Chri
