Ancient Egypt was a civilization of ancient North Africa, concentrated along the lower reaches of the Nile River in the place, now the country Egypt. Ancient Egyptian civilization followed prehistoric Egypt and coalesced around 3100 BC with the political unification of Upper and Lower Egypt under Menes; the history of ancient Egypt occurred as a series of stable kingdoms, separated by periods of relative instability known as Intermediate Periods: the Old Kingdom of the Early Bronze Age, the Middle Kingdom of the Middle Bronze Age and the New Kingdom of the Late Bronze Age. Egypt reached the pinnacle of its power in the New Kingdom, ruling much of Nubia and a sizable portion of the Near East, after which it entered a period of slow decline. During the course of its history Egypt was invaded or conquered by a number of foreign powers, including the Hyksos, the Libyans, the Nubians, the Assyrians, the Achaemenid Persians, the Macedonians under the command of Alexander the Great; the Greek Ptolemaic Kingdom, formed in the aftermath of Alexander's death, ruled Egypt until 30 BC, under Cleopatra, it fell to the Roman Empire and became a Roman province.
The success of ancient Egyptian civilization came from its ability to adapt to the conditions of the Nile River valley for agriculture. The predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which supported a more dense population, social development and culture. With resources to spare, the administration sponsored mineral exploitation of the valley and surrounding desert regions, the early development of an independent writing system, the organization of collective construction and agricultural projects, trade with surrounding regions, a military intended to assert Egyptian dominance. Motivating and organizing these activities was a bureaucracy of elite scribes, religious leaders, administrators under the control of a pharaoh, who ensured the cooperation and unity of the Egyptian people in the context of an elaborate system of religious beliefs; the many achievements of the ancient Egyptians include the quarrying and construction techniques that supported the building of monumental pyramids and obelisks.
Ancient Egypt has left a lasting legacy. Its art and architecture were copied, its antiquities carried off to far corners of the world, its monumental ruins have inspired the imaginations of writers for centuries. A new-found respect for antiquities and excavations in the early modern period by Europeans and Egyptians led to the scientific investigation of Egyptian civilization and a greater appreciation of its cultural legacy; the Nile has been the lifeline of its region for much of human history. The fertile floodplain of the Nile gave humans the opportunity to develop a settled agricultural economy and a more sophisticated, centralized society that became a cornerstone in the history of human civilization. Nomadic modern human hunter-gatherers began living in the Nile valley through the end of the Middle Pleistocene some 120,000 years ago. By the late Paleolithic period, the arid climate of Northern Africa became hot and dry, forcing the populations of the area to concentrate along the river region.
In Predynastic and Early Dynastic times, the Egyptian climate was much less arid. Large regions of Egypt were traversed by herds of grazing ungulates. Foliage and fauna were far more prolific in all environs and the Nile region supported large populations of waterfowl. Hunting would have been common for Egyptians, this is the period when many animals were first domesticated. By about 5500 BC, small tribes living in the Nile valley had developed into a series of cultures demonstrating firm control of agriculture and animal husbandry, identifiable by their pottery and personal items, such as combs and beads; the largest of these early cultures in upper Egypt was the Badari, which originated in the Western Desert. The Badari was followed by the Amratian and Gerzeh cultures, which brought a number of technological improvements; as early as the Naqada I Period, predynastic Egyptians imported obsidian from Ethiopia, used to shape blades and other objects from flakes. In Naqada II times, early evidence exists of contact with the Near East Canaan and the Byblos coast.
Over a period of about 1,000 years, the Naqada culture developed from a few small farming communities into a powerful civilization whose leaders were in complete control of the people and resources of the Nile valley. Establishing a power center at Nekhen, at Abydos, Naqada III leaders expanded their control of Egypt northwards along the Nile, they traded with Nubia to the south, the oases of the western desert to the west, the cultures of the eastern Mediterranean and Near East to the east, initiating a period of Egypt-Mesopotamia relations. The Naqada culture manufactured a diverse selection of material goods, reflective of the increasing power and wealth of the elite, as well as societal personal-use items, which included combs, small statuary, painted pottery, high quality decorative stone vases, cosmetic palettes, jewelry made of gold and ivory, they developed a ceramic glaze known as faience, used well into the Roman Per
Republicanism is a representative form of government organization. It is a political ideology centered on citizenship in a state organized as a republic, it ranges from the rule of a representative minority or oligarchy to popular sovereignty. It has had different definitions and interpretations which vary based on historical context and methodological approach. Republicanism may refer to the non-ideological scientific approach to politics and governance; as the republican thinker John Adams stated in the introduction to his famous Defense of the Constitution, the "science of politics is the science of social happiness" and a republic is the form of government arrived at when the science of politics is appropriately applied to the creation of a rationally designed government. Rather than being ideological, this approach focuses on applying a scientific methodology to the problems of governance through the rigorous study and application of past experience and experimentation in governance; this is the approach that may best be described to apply to republican thinkers such as Niccolò Machiavelli, John Adams, James Madison.
The word "republic" derives from the Latin noun-phrase res publica, which referred to the system of government that emerged in the 6th century BCE following the expulsion of the kings from Rome by Lucius Junius Brutus and Collatinus. This form of government in the Roman state collapsed in the latter part of the 1st century B. C. giving way to what was a monarchy in form, if not in name. Republics recurred subsequently, for example, Renaissance Florence or early modern Britain; the concept of a republic became a powerful force in Britain's North American colonies, where it contributed to the American Revolution. In Europe, it gained enormous influence through the French Revolution and through the First French Republic of 1792–1804. In Ancient Greece, several philosophers and historians analysed and described elements we now recognize as classical republicanism. Traditionally, the Greek concept of "politeia" was rendered into Latin as res publica. Political theory until recently used republic in the general sense of "regime".
There is no single written expression or definition from this era that corresponds with a modern understanding of the term "republic" but most of the essential features of the modern definition are present in the works of Plato and Polybius. These include theories of civic virtue. For example, in The Republic, Plato places great emphasis on the importance of civic virtue together with personal virtue on the part of the ideal rulers. Indeed, in Book V, Plato asserts that until rulers have the nature of philosophers or philosophers become the rulers, there can be no civic peace or happiness. A number of Ancient Greek city-states such as Athens and Sparta have been classified as "classical republics", because they featured extensive participation by the citizens in legislation and political decision-making. Aristotle considered Carthage to have been a republic as it had a political system similar to that of some of the Greek cities, notably Sparta, but avoided some of the defects that affected them.
Both Livy, a Roman historian, Plutarch, noted for his biographies and moral essays, described how Rome had developed its legislation, notably the transition from a kingdom to a republic, by following the example of the Greeks. Some of this history, composed more than 500 years after the events, with scant written sources to rely on, may be fictitious reconstruction; the Greek historian Polybius, writing in the mid-2nd century BCE, emphasized the role played by the Roman Republic as an institutional form in the dramatic rise of Rome's hegemony over the Mediterranean. In his writing on the constitution of the Roman Republic, Polybius described the system as being a "mixed" form of government. Polybius described the Roman system as a mixture of monarchy and democracy with the Roman Republic constituted in such a manner that it applied the strengths of each system to offset the weaknesses of the others. In his view, the mixed system of the Roman Republic provided the Romans with a much greater level of domestic tranquility than would have been experienced under another form of government.
Furthermore, Polybius argued, the comparative level of domestic tranquility the Romans enjoyed allowed them to conquer the Mediterranean. Polybius exerted a great influence on Cicero as he wrote his politico-philosophical works in the 1st century BCE. In one of these works, De re publica, Cicero linked the Roman concept of res publica to the Greek politeia; the modern term "republic", despite its derivation, is not synonymous with the Roman res publica. Among the several meanings of the term res publica, it is most translated "republic" where the Latin expression refers to the Roman state, its form of government, between the era of the Kings and the era of the Emperors; this Roman Republic would, by a modern understanding of the word, still be defined as a true republic if not coinciding entirely. Thus, Enlightenment philosophers saw the Roman Republic as an ideal system because it included features like a systematic separation of powers. Romans still called their state "Res Publica" in the era of the early emperors because, on the surface, the organization of the state had been preserved by the first emperors without significant alteration.
Several offices from the Republican era, held by individuals, were combined under the control of a single person. These changes became permanent, conferred sovereignty on the Emperor. Cicero's description of the ideal state, in De re Pu
Asimov's Science Fiction
Asimov's Science Fiction is an American science fiction magazine which publishes science fiction and fantasy named after science fiction author Isaac Asimov. It is published by Penny Publications. From January 2017, the publication frequency is bimonthly. Circulation in 2012 was 22,593. Asimov's Science Fiction began life as the digest-sized Isaac Asimov's Science Fiction Magazine in 1977. Joel Davis of Davis Publications approached Asimov to lend his name to a new science fiction magazine, after the fashion of Ellery Queen's Mystery Magazine or Alfred Hitchcock's Mystery Magazine. Asimov refused to act as editor, but served instead as editorial director, writing editorials and replying to reader mail until his death in 1992. At Asimov's request George Scithers, the first editor, negotiated an acquisitions contract with the Science Fiction Writers of America providing better terms for writers than had been the periodical standard up to that time. A quarterly, its first issue was dated December 1976.
It changed to a bimonthly in 1978 and began publishing monthly in 1979. In the mid-1980s it was published once every four weeks, with an extra "mid-December" issue. Double issues were added in the early 1990s before the schedule was scaled back to 10 issues per year by 2004. From January 2017, the schedule was changed to six "double-sized" issues per year; the magazine was sold to Bantam Doubleday Dell in January 1992, a few months before Asimov's death, the title changed to Asimov's Science Fiction. In 1996, Dell Magazines was acquired from BDD by Crosstown Publications, as of 2012 is part of Penny Publications, under the same ownership as Crosstown Publications has been, with headquarters in Norwalk and uses a combined Customer Service labelled Penny Press/Dell Magazines. In 1998, the magazine's size changed. Asimov's Science Fiction celebrated its thirtieth anniversary in 2007, with an anthology edited by the magazine's current editor, Sheila Williams. Drawing on stories published from 1977 to the present day, it was published by Tachyon Publications.
Martin Gardner wrote a regular column of "puzzle tales" for the magazine from 1977 to 1986. He produced 111 columns in all, many published in book form. George H. Scithers, 1977–1982 Kathleen Moloney, 1982-1983 Shawna McCarthy, 1983–1985 Gardner Dozois, 1986–2004 Sheila Williams, 2004–presentScithers left the magazine after five years, winning two Hugo awards as best editor, was succeeded by Shawna McCarthy. McCarthy held the position for three years. Gardner Dozois edited the magazine from 1985 to 2004, winning 15 Hugo awards, before stepping down and becoming its contributing editor. Sheila Williams is the current editor and won the Hugo Awards for Best Short Form Editor in 2011.

Dewey Decimal Classification
The Dewey Decimal Classification, colloquially the Dewey Decimal System, is a proprietary library classification system first published in the United States by Melvil Dewey in 1876. Described in a four-page pamphlet, it has been expanded to multiple volumes and revised through 23 major editions, the latest printed in 2011, it is available in an abridged version suitable for smaller libraries. OCLC, a non-profit cooperative that serves libraries maintains the system and licenses online access to WebDewey, a continuously updated version for catalogers; the Decimal Classification introduced the concepts of relative location and relative index which allow new books to be added to a library in their appropriate location based on subject. Libraries had given books permanent shelf locations that were related to the order of acquisition rather than topic; the classification's notation makes use of three-digit Arabic numerals for main classes, with fractional decimals allowing expansion for further detail.
Using Arabic numerals for symbols, it is flexible to the degree that numbers can be expanded in linear fashion to cover special aspects of general subjects. A library assigns a classification number that unambiguously locates a particular volume in a position relative to other books in the library, on the basis of its subject; the number makes it possible to find any book and to return it to its proper place on the library shelves. The classification system is used in 200,000 libraries in at least 135 countries. Melvil Dewey was self-declared reformer, he was a founding member of the American Library Association and can be credited with the promotion of card systems in libraries and business. He developed the ideas for his library classification system in 1873 while working at Amherst College library, he applied the classification to the books in that library, until in 1876 he had a first version of the classification. In 1876, he published the classification in pamphlet form with the title A Classification and Subject Index for Cataloguing and Arranging the Books and Pamphlets of a Library.
He used the pamphlet, published in more than one version during the year, to solicit comments from other librarians. It is not known who received copies or how many commented as only one copy with comments has survived, that of Ernest Cushing Richardson, his classification system was mentioned in an article in the first issue of the Library Journal and in an article by Dewey in the Department of Education publication "Public Libraries in America" in 1876. In March 1876, he applied for, received copyright on the first edition of the index; the edition was 44 pages in length, with 2,000 index entries, was printed in 200 copies. The second edition of the Dewey Decimal system, published in 1885 with the title Decimal Classification and Relativ Index for arranging and indexing public and private libraries and for pamflets, notes, scrap books, index rerums, etc. comprised 314 pages, with 10,000 index entries. Five hundred copies were produced. Editions 3–14, published between 1888 and 1942, used a variant of this same title.
Dewey modified and expanded his system for the second edition. In an introduction to that edition Dewey states that "nearly 100 persons hav contributed criticisms and suggestions". One of the innovations of the Dewey Decimal system was that of positioning books on the shelves in relation to other books on similar topics; when the system was first introduced, most libraries in the US used fixed positioning: each book was assigned a permanent shelf position based on the book's height and date of acquisition. Library stacks were closed to all but the most privileged patrons, so shelf browsing was not considered of importance; the use of the Dewey Decimal system increased during the early 20th century as librarians were convinced of the advantages of relative positioning and of open shelf access for patrons. New editions were readied as supplies of published editions were exhausted though some editions provided little change from the previous, as they were needed to fulfill demand. In the next decade, three editions followed on: the 3rd, 4th, 5th.
Editions 6 through 11 were published from 1899 to 1922. The 6th edition was published in a record 7,600 copies, although subsequent editions were much lower. During this time, the size of the volume grew, edition 12 swelled to 1243 pages, an increase of 25% over the previous edition. In response to the needs of smaller libraries which were finding the expanded classification schedules difficult to use, in 1894, the first abridged edition of the Dewey Decimal system was produced; the abridged edition parallels the full edition, has been developed for most full editions since that date. By popular request, in 1930, the Library of Congress began to print Dewey Classification numbers on nearly all of its cards, thus making the system available to all libraries making use of the Library of Congress card sets. Dewey's was not the only library classification available. Charles Ammi Cutter published the Expansive Classification in 1882, with initial encouragement from Melvil Dewey. Cutter's system was not adopted by many libraries, with one major exception: it was used as the basis for the Library of Congress Classification system.
In 1895, the International Institute of Bibliography, located in Belgium and led by Paul Otlet, contacted Dewey about the possibility of translating the classification into French, using the classification system for bibliographies. This would have
Science fiction is a genre of speculative fiction dealing with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, extraterrestrials in fiction. Science fiction explores the potential consequences of scientific other various innovations, has been called a "literature of ideas." "Science fiction" is difficult to define as it includes a wide range of concepts and themes. James Blish wrote: "Wells used the term to cover what we would today call'hard' science fiction, in which a conscientious attempt to be faithful to known facts was the substrate on which the story was to be built, if the story was to contain a miracle, it ought at least not to contain a whole arsenal of them."Isaac Asimov said: "Science fiction can be defined as that branch of literature which deals with the reaction of human beings to changes in science and technology." According to Robert A. Heinlein, "A handy short definition of all science fiction might read: realistic speculation about possible future events, based solidly on adequate knowledge of the real world and present, on a thorough understanding of the nature and significance of the scientific method."Lester del Rey wrote, "Even the devoted aficionado or fan—has a hard time trying to explain what science fiction is," and that the reason for there not being a "full satisfactory definition" is that "there are no delineated limits to science fiction."
Author and editor Damon Knight summed up the difficulty, saying "science fiction is what we point to when we say it." Mark C. Glassy described the definition of science fiction as U. S. Supreme Court Justice Potter Stewart did with the definition of pornography: "I know it when I see it." Science fiction had its beginnings in a time when the line between myth and fact was arguably more blurred than the present day. Written in the 2nd century CE by the satirist Lucian, A True Story contains many themes and tropes that are characteristic of contemporary science fiction, including travel to other worlds, extraterrestrial lifeforms, interplanetary warfare, artificial life; some consider it the first science-fiction novel. Some of the stories from The Arabian Nights, along with the 10th-century The Tale of the Bamboo Cutter and Ibn al-Nafis's 13th-century Theologus Autodidactus contain elements of science fiction. Products of the Age of Reason and the development of modern science itself, Johannes Kepler's Somnium, Francis Bacon's New Atlantis, Cyrano de Bergerac's Comical History of the States and Empires of the Moon and The States and Empires of the Sun, Margaret Cavendish's "The Blazing World", Jonathan Swift's Gulliver's Travels, Ludvig Holberg's Nicolai Klimii Iter Subterraneum and Voltaire's Micromégas are regarded as some of the first true science-fantasy works.
Indeed, Isaac Asimov and Carl Sagan considered Somnium the first science-fiction story. Following the 18th-century development of the novel as a literary form, Mary Shelley's books Frankenstein and The Last Man helped define the form of the science-fiction novel. Brian Aldiss has argued. Edgar Allan Poe wrote several stories considered science fiction, including "The Unparalleled Adventure of One Hans Pfaall" which featured a trip to the Moon. Jules Verne was noted for his attention to detail and scientific accuracy Twenty Thousand Leagues Under the Sea which predicted the contemporary nuclear submarine. In 1887, the novel El anacronópete by Spanish author Enrique Gaspar y Rimbau introduced the first time machine. Many critics consider H. G. Wells one of science fiction's most important authors, or "the Shakespeare of science fiction." His notable science-fiction works include The Time Machine, The Island of Doctor Moreau, The Invisible Man, The War of the Worlds. His science fiction imagined alien invasion, biological engineering and time travel.
In his non-fiction futurologist works he predicted the advent of airplanes, military tanks, nuclear weapons, satellite television, space travel, something resembling the World Wide Web. In 1912, Edgar Rice Burroughs published A Princess of Mars, the first of his three-decade-long planetary romance series of Barsoom novels, set on Mars and featuring John Carter as the hero. In 1926, Hugo Gernsback published the first American science-fiction magazine, Amazing Stories, in which he wrote: By'scientifiction' I mean the Jules Verne, H. G. Wells and Edgar Allan Poe type of story—a charming romance intermingled with scientific fact and prophetic vision... Not only do these amazing tales make tremendously interesting reading—they are always instructive, they supply knowledge... in a palatable form... New adventures pictured for us in the scientifiction of today are not at all impossible of realization tomorrow... Many great science stories destined to be of historical interest are still to be written...
Posterity will point to them as having blazed a new trail, not only in literature and fiction, but progress as well. In 1928, E. E. "Doc" Smith's first published work, The Skylark of Space, written in collaboration with Lee Hawkins Garby, appeared in Amazing Stories. It is called the first great space opera; the same year, Philip Francis Nowlan's original Buck Rogers story, Armageddon 2419 appeared in Amazing Stories. This was followed by the first serious science-fiction comic. In 1937, John W. Campbell became editor of Astounding Science Fiction, an event, sometimes conside
OCLC Online Computer Library Center, Incorporated d/b/a OCLC is an American nonprofit cooperative organization "dedicated to the public purposes of furthering access to the world's information and reducing information costs". It was founded in 1967 as the Ohio College Library Center. OCLC and its member libraries cooperatively produce and maintain WorldCat, the largest online public access catalog in the world. OCLC is funded by the fees that libraries have to pay for its services. OCLC maintains the Dewey Decimal Classification system. OCLC began in 1967, as the Ohio College Library Center, through a collaboration of university presidents, vice presidents, library directors who wanted to create a cooperative computerized network for libraries in the state of Ohio; the group first met on July 5, 1967 on the campus of the Ohio State University to sign the articles of incorporation for the nonprofit organization, hired Frederick G. Kilgour, a former Yale University medical school librarian, to design the shared cataloging system.
Kilgour wished to merge the latest information storage and retrieval system of the time, the computer, with the oldest, the library. The plan was to merge the catalogs of Ohio libraries electronically through a computer network and database to streamline operations, control costs, increase efficiency in library management, bringing libraries together to cooperatively keep track of the world's information in order to best serve researchers and scholars; the first library to do online cataloging through OCLC was the Alden Library at Ohio University on August 26, 1971. This was the first online cataloging by any library worldwide. Membership in OCLC is based on use of services and contribution of data. Between 1967 and 1977, OCLC membership was limited to institutions in Ohio, but in 1978, a new governance structure was established that allowed institutions from other states to join. In 2002, the governance structure was again modified to accommodate participation from outside the United States.
As OCLC expanded services in the United States outside Ohio, it relied on establishing strategic partnerships with "networks", organizations that provided training and marketing services. By 2008, there were 15 independent United States regional service providers. OCLC networks played a key role in OCLC governance, with networks electing delegates to serve on the OCLC Members Council. During 2008, OCLC commissioned two studies to look at distribution channels. In early 2009, OCLC negotiated new contracts with the former networks and opened a centralized support center. OCLC provides bibliographic and full-text information to anyone. OCLC and its member libraries cooperatively produce and maintain WorldCat—the OCLC Online Union Catalog, the largest online public access catalog in the world. WorldCat has holding records from private libraries worldwide; the Open WorldCat program, launched in late 2003, exposed a subset of WorldCat records to Web users via popular Internet search and bookselling sites.
In October 2005, the OCLC technical staff began a wiki project, WikiD, allowing readers to add commentary and structured-field information associated with any WorldCat record. WikiD was phased out; the Online Computer Library Center acquired the trademark and copyrights associated with the Dewey Decimal Classification System when it bought Forest Press in 1988. A browser for books with their Dewey Decimal Classifications was available until July 2013; until August 2009, when it was sold to Backstage Library Works, OCLC owned a preservation microfilm and digitization operation called the OCLC Preservation Service Center, with its principal office in Bethlehem, Pennsylvania. The reference management service QuestionPoint provides libraries with tools to communicate with users; this around-the-clock reference service is provided by a cooperative of participating global libraries. Starting in 1971, OCLC produced catalog cards for members alongside its shared online catalog. OCLC commercially sells software, such as CONTENTdm for managing digital collections.
It offers the bibliographic discovery system WorldCat Discovery, which allows for library patrons to use a single search interface to access an institution's catalog, database subscriptions and more. OCLC has been conducting research for the library community for more than 30 years. In accordance with its mission, OCLC makes its research outcomes known through various publications; these publications, including journal articles, reports and presentations, are available through the organization's website. OCLC Publications – Research articles from various journals including Code4Lib Journal, OCLC Research, Reference & User Services Quarterly, College & Research Libraries News, Art Libraries Journal, National Education Association Newsletter; the most recent publications are displayed first, all archived resources, starting in 1970, are available. Membership Reports – A number of significant reports on topics ranging from virtual reference in libraries to perceptions about library funding. Newsletters – Current and archived newsletters for the library and archive community.
Presentations – Presentations from both guest speakers and OCLC research from conferences and other events. The presentations are organized into five categories: Conference presentations, Dewey presentations, Distinguished Seminar Series, Guest presentations, Research staff
The Byzantine Empire referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic and military force in Europe. Both the terms "Byzantine Empire" and "Eastern Roman Empire" are historiographical terms created after the end of the realm. Several signal events from the 4th to 6th centuries mark the period of transition during which the Roman Empire's Greek East and Latin West diverged. Constantine I reorganised the empire, made Constantinople the new capital, legalised Christianity. Under Theodosius I, Christianity became the Empire's official state religion and other religious practices were proscribed.
Under the reign of Heraclius, the Empire's military and administration were restructured and adopted Greek for official use in place of Latin. Thus, although the Roman state continued and its traditions were maintained, modern historians distinguish Byzantium from ancient Rome insofar as it was centred on Constantinople, oriented towards Greek rather than Latin culture, characterised by Eastern Orthodox Christianity; the borders of the empire evolved over its existence, as it went through several cycles of decline and recovery. During the reign of Justinian I, the empire reached its greatest extent after reconquering much of the Roman western Mediterranean coast, including North Africa and Rome itself, which it held for two more centuries; the Byzantine–Sasanian War of 602–628 exhausted the empire's resources and contributed to major territorial losses during the Early Muslim conquests of the 7th century, when it lost its richest provinces and Syria, to the Arab caliphate. During the Macedonian dynasty, the empire expanded again and experienced the two-century long Macedonian Renaissance, which came to an end with the loss of much of Asia Minor to the Seljuk Turks after the Battle of Manzikert in 1071.
This battle opened the way for the Turks to settle in Anatolia. The empire recovered during the Komnenian restoration, by the 12th century Constantinople was the largest and wealthiest European city. However, it was delivered a mortal blow during the Fourth Crusade, when Constantinople was sacked in 1204 and the territories that the empire governed were divided into competing Byzantine Greek and Latin realms. Despite the eventual recovery of Constantinople in 1261, the Byzantine Empire remained only one of several small rival states in the area for the final two centuries of its existence, its remaining territories were progressively annexed by the Ottomans over the 15th century. The Fall of Constantinople to the Ottoman Empire in 1453 ended the Byzantine Empire; the last of the imperial Byzantine successor states, the Empire of Trebizond, would be conquered by the Ottomans eight years in the 1461 Siege of Trebizond. The first use of the term "Byzantine" to label the years of the Roman Empire was in 1557, when the German historian Hieronymus Wolf published his work Corpus Historiæ Byzantinæ, a collection of historical sources.
The term comes from "Byzantium", the name of the city of Constantinople before it became Constantine's capital. This older name of the city would be used from this point onward except in historical or poetic contexts; the publication in 1648 of the Byzantine du Louvre, in 1680 of Du Cange's Historia Byzantina further popularised the use of "Byzantine" among French authors, such as Montesquieu. However, it was not until the mid-19th century that the term came into general use in the Western world; the Byzantine Empire was known to its inhabitants as the "Roman Empire", the "Empire of the Romans", "Romania", the "Roman Republic", as "Rhōmais". The inhabitants called themselves Romaioi and as late as the 19th century Greeks referred to Modern Greek as Romaiika "Romaic." After 1204 when the Byzantine Empire was confined to its purely Greek provinces the term'Hellenes' was used instead. While the Byzantine Empire had a multi-ethnic character during most of its history and preserved Romano-Hellenistic traditions, it became identified by its western and northern contemporaries with its predominant Greek element.
The occasional use of the term "Empire of the Greeks" in the West to refer to the Eastern Roman Empire and of the Byzantine Emperor as Imperator Graecorum were used to separate it from the prestige of the Roman Empire within the new kingdoms of the West. No such distinction existed in the Islamic and Slavic worlds, where the Empire was more straightforwardly seen as the continuation of the Roman Empire. In the Islamic world, the Roman Empire was known as Rûm; the name millet-i Rûm, or "Roman nation," was used by the Ottomans through the 20th century to refer to the former subjects of the Byzantine Empire
