Dating
–
It can be a form of courtship consisting of social activities done by the couple. The protocols and practices of dating, and the used to describe it, vary considerably from country to country. While the term has several meanings, the most frequent usage refers to two or more people exploring whether they are romantically or sexually compatible by participating in dates with the other, with the use of modern technology, people can date via telephone or computer or meet in person. This term may refer to two or more people who have already decided they share romantic or sexual feelings toward each other. These people will have dates on a basis, and they may or may not be having sexual relations. This period of courtship is sometimes seen as a precursor to engagement or marriage, some cultures require people to wait until a certain age to begin dating, which has been a source of controversy. Dating as an institution is a recent phenomenon which has mainly emerged in the last few centuries. Humans have been compared to species in terms of sexual behavior. According to Sapolsky, humans are somewhat in the middle of this spectrum, in the sense that humans form pair bonds and these species-particular behavior patterns provide a context for aspects of human reproduction, including dating. However, one particularity of the species is that pair bonds are often formed without necessarily having the intention of reproduction. Thus, the concept of marriage is changing widely in many countries, accordingly, there was little need for a temporary trial period such as dating before a permanent community-recognized union was formed between a man and a woman. The 12th-century book The Art of Courtly Love advised that True love can have no place between husband and wife, according to one view, clandestine meetings between men and women, generally outside of marriage or before marriage, were the precursors to todays dating. From about 1700 a worldwide movement perhaps described as the empowerment of the individual took hold, leading towards greater emancipation of women, men and women became more equal politically, financially, and socially in many nations. Women eventually won the right to vote in many countries and own property and receive treatment by the law. In many societies, individuals could decide—on their own—whether they should marry, whom they should marry, and when they should marry. In the twentieth century, dating was sometimes seen as a precursor to marriage but it could also be considered as an end-in-itself, that is, an informal social activity akin to friendship. Rapidly developing technology played a role, new communication technology such as the telephone, Internet. Cars extended the range of dating as well as enabled back-seat sexual exploration, new types of relationships formed, it was possible for people to live together without marrying and without children

Russian Empire
–
The Russian Empire was a state that existed from 1721 until it was overthrown by the short-lived February Revolution in 1917. One of the largest empires in history, stretching over three continents, the Russian Empire was surpassed in landmass only by the British and Mongol empires. The rise of the Russian Empire happened in association with the decline of neighboring powers, the Swedish Empire, the Polish–Lithuanian Commonwealth, Persia. It played a role in 1812–14 in defeating Napoleons ambitions to control Europe. The House of Romanov ruled the Russian Empire from 1721 until 1762, and its German-descended cadet branch, with 125.6 million subjects registered by the 1897 census, it had the third-largest population in the world at the time, after Qing China and India. Like all empires, it included a large disparity in terms of economics, ethnicity, there were numerous dissident elements, who launched numerous rebellions and assassination attempts, they were closely watched by the secret police, with thousands exiled to Siberia. Economically, the empire had an agricultural base, with low productivity on large estates worked by serfs. The economy slowly industrialized with the help of foreign investments in railways, the land was ruled by a nobility from the 10th through the 17th centuries, and subsequently by an emperor. Tsar Ivan III laid the groundwork for the empire that later emerged and he tripled the territory of his state, ended the dominance of the Golden Horde, renovated the Moscow Kremlin, and laid the foundations of the Russian state. Tsar Peter the Great fought numerous wars and expanded an already huge empire into a major European power, Catherine the Great presided over a golden age. She expanded the state by conquest, colonization and diplomacy, continuing Peter the Greats policy of modernisation along West European lines, Tsar Alexander II promoted numerous reforms, most dramatically the emancipation of all 23 million serfs in 1861. His policy in Eastern Europe involved protecting the Orthodox Christians under the rule of the Ottoman Empire and that connection by 1914 led to Russias entry into the First World War on the side of France, Britain, and Serbia, against the German, Austrian and Ottoman empires. The Russian Empire functioned as a monarchy until the Revolution of 1905. The empire collapsed during the February Revolution of 1917, largely as a result of failures in its participation in the First World War. Perhaps the latter was done to make Europe recognize Russia as more of a European country, Poland was divided in the 1790-1815 era, with much of the land and population going to Russia. Most of the 19th century growth came from adding territory in Asia, Peter I the Great introduced autocracy in Russia and played a major role in introducing his country to the European state system. However, this vast land had a population of 14 million, grain yields trailed behind those of agriculture in the West, compelling nearly the entire population to farm. Only a small percentage lived in towns, the class of kholops, close to the one of slavery, remained a major institution in Russia until 1723, when Peter I converted household kholops into house serfs, thus including them in poll taxation

Adoption of the Gregorian calendar
–
For many the new style calendar is only used for civil purposes and the old style calendar remains used in religious contexts. In the western world, the change was a date shift from the previous Julian Calendar. Today, the Gregorian calendar is internationally the worlds most widely used civil calendar. During – and for some time after – the change between systems, it has been common to use the terms Old Style and New Style when giving dates, to indicate which calendar was used to reckon them. Although Gregorys reform was enacted in the most solemn of forms available to the Church, the bull had no authority beyond the Catholic Church, the changes that he was proposing were changes to the civil calendar, over which he had no authority. They required adoption by the authorities in each country to have legal effect. The bull became the law of the Catholic Church in 1582, but it was not recognised by Protestant churches, Orthodox churches. Consequently, the days on which Easter and related holidays were celebrated by different Christian churches again diverged, when converting a date that occurs in a leap year on one calendar but not the other, include 29 February in the calculation if the conversion spans the February/March month change. A month after having decreed the reform, the granted to one Antoni Lilio the exclusive right to publish the calendar for a period of ten years. The papal brief was revoked on 20 September 1582, because Antonio Lilio proved unable to keep up with the demand for copies. Catholic states such as France, the Italian principalities, Poland, Spain, Portugal, Thursday,4 October 1582 was followed by Friday,15 October 1582, with ten days missing. Countries that did not change until the 18th century had by then observed an additional leap year, some countries did not change until the 19th or 20th century, necessitating one or two more missing days. France adopted the new calendar with Sunday,9 December 1582, the seven Catholic Swiss cantons adopted the new calendar in January 1684 while Geneva and several Protestant cantons adopted it in January 1701 or at other dates throughout the 18th century. The two Swiss communes of Schiers and Grüsch there the last areas of Western and Central Europe to switch to the Gregorian calendar in 1812. Many Protestant countries initially objected to adopting a Catholic innovation, some Protestants feared the new calendar was part of a plot to return them to the Catholic fold, in the Czech lands, Protestants resisted the calendar imposed by the Habsburg Monarchy. They finally adopted the Gregorian calculation of Easter in 1774, the remaining provinces of the Dutch Republic adopted the Gregorian calendar on 12 July 1700,12 December 1700,12 January 1701 and 12 May 1701. Swedens relationship with the Gregorian calendar was a difficult one and this system had potential for confusion when working out the dates of Swedish events in this 40-year period. To add to the confusion, the system was administered

Europe
–
Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, yet the non-oceanic borders of Europe—a concept dating back to classical antiquity—are arbitrary. Europe covers about 10,180,000 square kilometres, or 2% of the Earths surface, politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a population of about 740 million as of 2015. Further from the sea, seasonal differences are more noticeable than close to the coast, Europe, in particular ancient Greece, was the birthplace of Western civilization. The fall of the Western Roman Empire, during the period, marked the end of ancient history. Renaissance humanism, exploration, art, and science led to the modern era, from the Age of Discovery onwards, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at times the Americas, most of Africa, Oceania. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to economic, cultural, and social change in Western Europe. During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east, until the revolutions of 1989 and fall of the Berlin Wall. In 1955, the Council of Europe was formed following a speech by Sir Winston Churchill and it includes all states except for Belarus, Kazakhstan and Vatican City. Further European integration by some states led to the formation of the European Union, the EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The European Anthem is Ode to Joy and states celebrate peace, in classical Greek mythology, Europa is the name of either a Phoenician princess or of a queen of Crete. The name contains the elements εὐρύς, wide, broad and ὤψ eye, broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. For the second part also the divine attributes of grey-eyed Athena or ox-eyed Hera. The same naming motive according to cartographic convention appears in Greek Ανατολή, Martin Litchfield West stated that phonologically, the match between Europas name and any form of the Semitic word is very poor. Next to these there is also a Proto-Indo-European root *h1regʷos, meaning darkness. Most major world languages use words derived from Eurṓpē or Europa to refer to the continent, in some Turkic languages the originally Persian name Frangistan is used casually in referring to much of Europe, besides official names such as Avrupa or Evropa

British Empire
–
The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states. It originated with the possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, 23% of the population at the time. As a result, its political, legal, linguistic and cultural legacy is widespread, during the Age of Discovery in the 15th and 16th centuries, Portugal and Spain pioneered European exploration of the globe, and in the process established large overseas empires. Envious of the great wealth these empires generated, England, France, the independence of the Thirteen Colonies in North America in 1783 after the American War of Independence caused Britain to lose some of its oldest and most populous colonies. British attention soon turned towards Asia, Africa, and the Pacific, after the defeat of France in the Revolutionary and Napoleonic Wars, Britain emerged as the principal naval and imperial power of the 19th century. In the early 19th century, the Industrial Revolution began to transform Britain, the British Empire expanded to include India, large parts of Africa and many other territories throughout the world. In Britain, political attitudes favoured free trade and laissez-faire policies, during the 19th Century, Britains population increased at a dramatic rate, accompanied by rapid urbanisation, which caused significant social and economic stresses. To seek new markets and sources of raw materials, the Conservative Party under Benjamin Disraeli launched a period of imperialist expansion in Egypt, South Africa, Canada, Australia, and New Zealand became self-governing dominions. By the start of the 20th century, Germany and the United States had begun to challenge Britains economic lead, subsequent military and economic tensions between Britain and Germany were major causes of the First World War, during which Britain relied heavily upon its empire. The conflict placed enormous strain on the military, financial and manpower resources of Britain, although the British Empire achieved its largest territorial extent immediately after World War I, Britain was no longer the worlds pre-eminent industrial or military power. In the Second World War, Britains colonies in Southeast Asia were occupied by Imperial Japan, despite the final victory of Britain and its allies, the damage to British prestige helped to accelerate the decline of the empire. India, Britains most valuable and populous possession, achieved independence as part of a larger movement in which Britain granted independence to most territories of the empire. The transfer of Hong Kong to China in 1997 marked for many the end of the British Empire, fourteen overseas territories remain under British sovereignty. After independence, many former British colonies joined the Commonwealth of Nations, the United Kingdom is now one of 16 Commonwealth nations, a grouping known informally as the Commonwealth realms, that share a monarch, Queen Elizabeth II. The foundations of the British Empire were laid when England and Scotland were separate kingdoms. In 1496, King Henry VII of England, following the successes of Spain and Portugal in overseas exploration, Cabot led another voyage to the Americas the following year but nothing was ever heard of his ships again

John Dee
–
John Dee was an English mathematician, astronomer, astrologer, occult philosopher, and advisor to Queen Elizabeth I. He devoted much of his life to the study of alchemy, divination and he was also an advocate of Englands imperial expansion. Dee straddled the worlds of science and magic just as they were becoming distinguishable, one of the most learned men of his age, he had been invited to lecture on the geometry of Euclid at the University of Paris while still in his early twenties. Dee was an ardent promoter of mathematics and an astronomer, as well as a leading expert in navigation. Simultaneously with these efforts, Dee immersed himself in the worlds of magic, astrology, in his lifetime, Dee amassed one of the largest libraries in England. His high status as a scholar also allowed him to play a role in Elizabethan politics and he served as an occasional advisor and tutor to Elizabeth I and nurtured relationships with her ministers Francis Walsingham and William Cecil. Dee also tutored and enjoyed patronage relationships with Sir Philip Sidney, his uncle Robert Dudley, 1st Earl of Leicester and he also enjoyed patronage from Sir Christopher Hatton. Dee was born in Tower Ward, London, to Rowland Dee of Welsh descent and his surname Dee derived from the Welsh du, his grandfather was Bedo Ddu of Nant-y-groes, Pilleth, Radnorshire, and John retained his connection with the locality. His father Roland was a mercer and gentleman courtier to Henry VIII, John Dee claimed to be a descendant of Rhodri the Great, Prince of Wales and constructed a pedigree showing his descent from Rhodri. Dees family arrived in London in the wake of Henry Tudors coronation as Henry VII, Jane Dee was the daughter of William Wild. Dee attended the Chelmsford Chantry School from 1535 to 1542 and he entered St Johns College, Cambridge, in November 1542, aged 15, graduating BA in 1545 or early 1546. His abilities recognised, he became a fellow of Trinity College, Cambridge. At Trinity, the stage effects he produced for a production of Aristophanes Peace procured him the reputation of being a magician that clung to him through life. In the late 1540s and early 1550s, he travelled in Europe, studying at Louvain and Brussels, in 1552, he met Gerolamo Cardano in London, during their acquaintance they investigated a perpetual motion machine as well as a gem purported to have magical properties. Rector at Upton-upon-Severn from 1553, Dee was offered a readership in mathematics at Oxford in 1554, in 1555, Dee became a member of the Worshipful Company of Mercers, as his father had, through the companys system of patrimony. That same year,1555, he was arrested and charged with calculating for having cast horoscopes of Queen Mary and Princess Elizabeth, Dee appeared in the Star Chamber and exonerated himself, but was turned over to the Catholic Bishop Bonner for religious examination. His strong and lifelong penchant for secrecy perhaps worsening matters, this episode was only the most dramatic in a series of attacks. Clearing his name yet again, he became a close associate of Bonner

England
–
England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west, the Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east, the country covers five-eighths of the island of Great Britain in its centre and south, and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. England became a state in the 10th century, and since the Age of Discovery. The Industrial Revolution began in 18th-century England, transforming its society into the worlds first industrialised nation, Englands terrain mostly comprises low hills and plains, especially in central and southern England. However, there are uplands in the north and in the southwest, the capital is London, which is the largest metropolitan area in both the United Kingdom and the European Union. In 1801, Great Britain was united with the Kingdom of Ireland through another Act of Union to become the United Kingdom of Great Britain and Ireland. In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain, the name England is derived from the Old English name Englaland, which means land of the Angles. The Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages, the Angles came from the Angeln peninsula in the Bay of Kiel area of the Baltic Sea. The earliest recorded use of the term, as Engla londe, is in the ninth century translation into Old English of Bedes Ecclesiastical History of the English People. According to the Oxford English Dictionary, its spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, the etymology of the tribal name itself is disputed by scholars, it has been suggested that it derives from the shape of the Angeln peninsula, an angular shape. An alternative name for England is Albion, the name Albion originally referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus, specifically the 4th century BC De Mundo, in it are two very large islands called Britannia, these are Albion and Ierne. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, the word Albion or insula Albionum has two possible origins. Albion is now applied to England in a poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England, Lloegr, the earliest known evidence of human presence in the area now known as England was that of Homo antecessor, dating to approximately 780,000 years ago. The oldest proto-human bones discovered in England date from 500,000 years ago, Modern humans are known to have inhabited the area during the Upper Paleolithic period, though permanent settlements were only established within the last 6,000 years

Meiji period
–
The Meiji period, also known as the Meiji era, is a Japanese era which extended from October 23,1868 through July 30,1912. This period represents the first half of the Empire of Japan during which Japanese society moved from being a feudal society to its modern form. Fundamental changes affected its structure, internal politics, economy, military. The period corresponded with the reign of Emperor Meiji after 1868 and it was succeeded by the Taishō period upon the accession of Emperor Taishō to the throne. On February 3,1867, the 14-year-old Prince Mutsuhito succeeded his father, Emperor Kōmei, on November 9,1867, then-Shogun Tokugawa Yoshinobu tendered his resignation to the Emperor, and formally stepped down ten days later. Imperial restoration occurred the year on January 3,1868. The fall of Edo in the summer of 1868 marked the end of the Tokugawa shogunate, and a new era, Meiji, was proclaimed. The first reform was the promulgation of the Five Charter Oath in 1868, implicit in the Charter Oath was an end to exclusive political rule by the bakufu, and a move toward more democratic participation in government. To implement the Charter Oath, a rather short-lived constitution with eleven articles was drawn up in June 1868, the Meiji government assured the foreign powers that it would follow the old treaties negotiated by the bakufu and announced that it would act in accordance with international law. Mutsuhito, who was to reign until 1912, selected a new reign title—Meiji, to further dramatize the new order, the capital was relocated from Kyoto, where it had been situated since 794, to Tokyo, the new name for Edo. Confirmed in their positions, the daimyo became governors. The han were replaced with prefectures in 1871, and authority continued to flow to the national government, officials from the favored former han, such as Satsuma, Chōshū, Tosa, and Hizen staffed the new ministries. Formerly old court nobles, and lower-ranking but more radical samurai, replaced bakufu appointees, in as much as the Meiji Restoration had sought to return the Emperor to a preeminent position, efforts were made to establish a Shinto-oriented state much like it was 1,000 years earlier. Furthermore, a new State Shinto had to be constructed for the purpose, in 1871, the Office of Shinto Worship was established, ranking even above the Council of State in importance. The kokutai ideas of the Mito school were embraced, and the ancestry of the Imperial House was emphasized. The government supported Shinto teachers, a small but important move, although the Office of Shinto Worship was demoted in 1872, by 1877 the Home Ministry controlled all Shinto shrines and certain Shinto sects were given state recognition. Shinto was released from Buddhist administration and its properties restored, although Buddhism suffered from state sponsorship of Shinto, it had its own resurgence. Christianity also was legalized, and Confucianism remained an important ethical doctrine, increasingly, however, Japanese thinkers identified with Western ideology and methods

Korean Empire
–
The Korean Empire was proclaimed in October 1897, after the Donghak Peasant Revolution of 1894 to 1895 and Gabo Reforms that swept the country from 1894 to 1896. It lasted until the annexation of Korea by Japan in August 1910, Emperor Gojong oversaw the partial modernization of the military, economy, land system, education system, and various industries. Korea in the Joseon Dynasty had been a client kingdom of China in the Qing Dynasty. Towards the end of the 19th century, influence over Korea was increasingly an area of conflict between the Qing and Japan, with its newfound preeminence over the waning and weak Qing dynasty, Japan had delegates negotiate the Treaty of Shimonoseki with the Qing dynasty. Through signing the treaty, a designed to prevent the southern expansion of Russia, Japan wrested control over the Liaodong Peninsula from Qing. Queen Min, the consort of King Gojong, also recognized this change, Queen Min began to emerge as a key figure in higher-level Korean counteraction against Japanese influence. With the assassination of his wife Queen Min, King Gojong, during the time from Queen Mins death to the kings return from Russian protection, Korea underwent another major upheaval both at home and abroad. By 1894, new laws passed by progressives and reformers in the royal cabinet forced through long-desired reforms aimed at revamping Koreas antiquated society and these laws were called the Gabo Reform, referring to the year in which they began. Meanwhile, the new reforms aimed at modernizing Korean society soon attracted controversy from within and this led to the uprising of the Eulmi temporary armies aimed at avenging the assassination of Queen Min. In 1897, King Gojong, yielding to rising pressure from overseas and the demands of the Independence Association-led public opinion, returned to Gyŏngungung. Gojong became the Gwangmu Emperor, the first imperial head of state and this marked the complete end of the old world order and traditional amicable dependency system in the Far East. The significance of the declaration of an Empire, in the Korean understanding of the situation was to declare Koreas independence from others, historically, the usage of Emperor was reserved only for the Chinese Emperor, the Son of Heaven. Korean dynasties had acknowledged themselves as vassals of the Chinese, and had refrained from declaring their equality with China. When Japan experienced the Meiji Restoration, the Emperor of Japan was declared the source of sovereignty in the Japanese government, upon receiving news of the Meiji restoration from Japan, the Korean government refused to acknowledge the change. Not only did it challenge the primacy of the Chinese emperor as the suzerains of Korea but Japans address also addressed Korea as an equal, the change in title for Korea to empire only became possible after the Sino-Japanese war. A group of Korean officials and intellectuals felt great necessity of the reform of the country. More and more intellectuals were informed of the Western civilization and became conscious of the powerful nations of Europe. Later, the progressives within the group initiated The Gabo Reform in 1894, American missionaries, who had close relationships with the Korean royal court, also helped the propagation of Western culture

China
–
China, officially the Peoples Republic of China, is a unitary sovereign state in East Asia and the worlds most populous country, with a population of over 1.381 billion. The state is governed by the Communist Party of China and its capital is Beijing, the countrys major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a power and a major regional power within Asia. Chinas landscape is vast and diverse, ranging from forest steppes, the Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from much of South and Central Asia. The Yangtze and Yellow Rivers, the third and sixth longest in the world, respectively, Chinas coastline along the Pacific Ocean is 14,500 kilometers long and is bounded by the Bohai, Yellow, East China and South China seas. China emerged as one of the worlds earliest civilizations in the basin of the Yellow River in the North China Plain. For millennia, Chinas political system was based on hereditary monarchies known as dynasties, in 1912, the Republic of China replaced the last dynasty and ruled the Chinese mainland until 1949, when it was defeated by the communist Peoples Liberation Army in the Chinese Civil War. The Communist Party established the Peoples Republic of China in Beijing on 1 October 1949, both the ROC and PRC continue to claim to be the legitimate government of all China, though the latter has more recognition in the world and controls more territory. China had the largest economy in the world for much of the last two years, during which it has seen cycles of prosperity and decline. Since the introduction of reforms in 1978, China has become one of the worlds fastest-growing major economies. As of 2016, it is the worlds second-largest economy by nominal GDP, China is also the worlds largest exporter and second-largest importer of goods. China is a nuclear weapons state and has the worlds largest standing army. The PRC is a member of the United Nations, as it replaced the ROC as a permanent member of the U. N. Security Council in 1971. China is also a member of numerous formal and informal multilateral organizations, including the WTO, APEC, BRICS, the Shanghai Cooperation Organization, the BCIM, the English name China is first attested in Richard Edens 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. The demonym, that is, the name for the people, Portuguese China is thought to derive from Persian Chīn, and perhaps ultimately from Sanskrit Cīna. Cīna was first used in early Hindu scripture, including the Mahābhārata, there are, however, other suggestions for the derivation of China. The official name of the state is the Peoples Republic of China. The shorter form is China Zhōngguó, from zhōng and guó and it was then applied to the area around Luoyi during the Eastern Zhou and then to Chinas Central Plain before being used as an occasional synonym for the state under the Qing

Arabic numerals
–
In this numeral system, a sequence of digits such as 975 is read as a single number, using the position of the digit in the sequence to interpret its value. The symbol for zero is the key to the effectiveness of the system, the system was adopted by Arab mathematicians in Baghdad and passed on to the Arabs farther west. There is some evidence to suggest that the numerals in their current form developed from Arabic letters in the Maghreb, the current form of the numerals developed in North Africa, distinct in form from the Indian and eastern Arabic numerals. The use of Arabic numerals spread around the world through European trade, books, the term Arabic numerals is ambiguous. It most commonly refers to the widely used in Europe. Arabic numerals is also the name for the entire family of related numerals of Arabic. It may also be intended to mean the numerals used by Arabs and it would be more appropriate to refer to the Arabic numeral system, where the value of a digit in a number depends on its position. The decimal Hindu–Arabic numeral system was developed in India by AD700, the development was gradual, spanning several centuries, but the decisive step was probably provided by Brahmaguptas formulation of zero as a number in AD628. The system was revolutionary by including zero in positional notation, thereby limiting the number of digits to ten. It is considered an important milestone in the development of mathematics, one may distinguish between this positional system, which is identical throughout the family, and the precise glyphs used to write the numerals, which varied regionally. The glyphs most commonly used in conjunction with the Latin script since early modern times are 0123456789. The first universally accepted inscription containing the use of the 0 glyph in India is first recorded in the 9th century, in an inscription at Gwalior in Central India dated to 870. Numerous Indian documents on copper plates exist, with the symbol for zero in them, dated back as far as the 6th century AD. Inscriptions in Indonesia and Cambodia dating to AD683 have also been found and their work was principally responsible for the diffusion of the Indian system of numeration in the Middle East and the West. In the 10th century, Middle-Eastern mathematicians extended the decimal system to include fractions. The decimal point notation was introduced by Sind ibn Ali, who wrote the earliest treatise on Arabic numerals. Ghubar numerals themselves are probably of Roman origin, some popular myths have argued that the original forms of these symbols indicated their numeric value through the number of angles they contained, but no evidence exists of any such origin. In 825 Al-Khwārizmī wrote a treatise in Arabic, On the Calculation with Hindu Numerals, Algoritmi, the translators rendition of the authors name, gave rise to the word algorithm

Hirohito
–
Emperor Shōwa was the 124th Emperor of Japan according to the traditional order of succession, reigning from December 25,1926, until his death on January 7,1989. He was succeeded by his eldest son, Akihito, upon his death, although better known outside Japan by his personal name Hirohito, in Japan, he is now referred to primarily by his posthumous name Emperor Shōwa. The word Shōwa is the name of the era that corresponded with the Emperors reign, the name Hirohito means abundant benevolence.

When his grandfather, Emperor Meiji, died on July 30,1912, Hirohitos father, Yoshihito, assumed the throne, in 1914, he was promoted to the ranks of lieutenant in the army and sub-lieutenant in the navy, then to captain and lieutenant in 1916. He was formally proclaimed Crown Prince and heir apparent on November 2,1916, Hirohito attended Gakushūin Peers School from 1908 to 1914 and then a special institute for the crown prince from 1914 to 1921. In 1920, Hirohito was promoted to the rank of Major in the army, in 1921, Hirohito took a six-month tour of Western Europe, including the United Kingdom, France, Italy, the Netherlands, and Belgium. After his return to Japan, he became Regent of Japan on November 29,1921, in 1923, he was promoted to the rank of Lieutenant-Colonel in the army and Commander in the navy, and to army Colonel and Navy Captain in 1925.
