Algeria
–
Algeria, officially the Peoples Democratic Republic of Algeria, is a sovereign state in North Africa on the Mediterranean coast. Its capital and most populous city is Algiers, located in the far north. With an area of 2,381,741 square kilometres, Algeria is the tenth-largest country in the world, the country is a semi-presidential republic consisting of 48 provinces and 1,541 communes. Abdelaziz Bouteflika has been President since 1999, Berbers are the indigenous inhabitants of Algeria. Algeria is a regional and middle power, the North African country supplies large amounts of natural gas to Europe, and energy exports are the backbone of the economy. According to OPEC Algeria has the 16th largest oil reserves in the world, Sonatrach, the national oil company, is the largest company in Africa. Algeria has one of the largest militaries in Africa and the largest defence budget on the continent, most of Algerias weapons are imported from Russia, with whom they are a close ally. Algeria is a member of the African Union, the Arab League, OPEC, the countrys name derives from the city of Algiers. The citys name in turn derives from the Arabic al-Jazāir, a form of the older Jazāir Banī Mazghanna. In the region of Ain Hanech, early remnants of hominid occupation in North Africa were found, neanderthal tool makers produced hand axes in the Levalloisian and Mousterian styles similar to those in the Levant. Algeria was the site of the highest state of development of Middle Paleolithic Flake tool techniques, tools of this era, starting about 30,000 BC, are called Aterian. The earliest blade industries in North Africa are called Iberomaurusian and this industry appears to have spread throughout the coastal regions of the Maghreb between 15,000 and 10,000 BC. Neolithic civilization developed in the Saharan and Mediterranean Maghreb perhaps as early as 11,000 BC or as late as between 6000 and 2000 BC and this life, richly depicted in the Tassili nAjjer paintings, predominated in Algeria until the classical period. The amalgam of peoples of North Africa coalesced eventually into a native population that came to be called Berbers. These settlements served as market towns as well as anchorages, as Carthaginian power grew, its impact on the indigenous population increased dramatically. Berber civilization was already at a stage in which agriculture, manufacturing, trade, by the early 4th century BC, Berbers formed the single largest element of the Carthaginian army. In the Revolt of the Mercenaries, Berber soldiers rebelled from 241 to 238 BC after being unpaid following the defeat of Carthage in the First Punic War. They succeeded in obtaining control of much of Carthages North African territory, the Carthaginian state declined because of successive defeats by the Romans in the Punic Wars

Central bank
–
A central bank, reserve bank, or monetary authority is an institution that manages a states currency, money supply, and interest rates. Central banks also usually oversee the commercial banking system of their respective countries, Central banks in most developed nations are institutionally designed to be independent from political interference. Still, limited control by the executive and legislative bodies usually exists, prior to the 17th century most money was commodity money, typically gold or silver. However, promises to pay were widely circulated and accepted as value at least five hundred years earlier in both Europe and Asia. The Song dynasty was the first to issue generally circulating paper currency, in 1455, in an effort to control inflation, the succeeding Ming Dynasty ended the use of paper money and closed much of Chinese trade. The Bank of Amsterdam, established in the Dutch Republic in 1609, is considered to be the forerunner to modern central banks. The Wisselbanks innovations helped lay the foundations for the birth and development of the banking system that now plays a vital role in the worlds economy. Along with a number of local banks, it performed many functions of a central banking system. Lucien Gillard calls it the European guilder, and Adam Smith devotes many pages to explaining how the bank guilder works, the model of the Wisselbank as a state bank was adapted throughout Europe, including the Bank of Sweden and the Bank of England. Established by Dutch-Latvian Johan Palmstruch in 1668, Sveriges Riksbank is often considered by many as the worlds oldest central bank, the lenders would give the government cash and also issue notes against the government bonds, which could be lent again. A Royal Charter was granted on 27 July through the passage of the Tonnage Act 1694, the bank was given exclusive possession of the governments balances, and was the only limited-liability corporation allowed to issue banknotes. The £1. 2M was raised in 12 days, half of this was used to rebuild the Navy and these modern central banking functions evolved slowly through the 18th and 19th centuries. The currency crisis of 1797, caused by panicked depositors withdrawing from the Bank led to the government suspending convertibility of notes into specie payment. The bank was accused by the bullionists of causing the exchange rate to fall from over issuing banknotes. Nevertheless, it was clear that the Bank was being treated as an organ of the state, henry Thornton, a merchant banker and monetary theorist has been described as the father of the modern central bank. An opponent of the real bills doctrine, he was a defender of the bullionist position, thorntons process of monetary expansion anticipated the theories of Knut Wicksell regarding the cumulative process which restates the Quantity Theory in a theoretically coherent form. Until the mid-nineteenth century, commercial banks were able to issue their own banknotes, many consider the origins of the central bank to lie with the passage of the Bank Charter Act of 1844. Under this law, authorisation to issue new banknotes was restricted to the Bank of England, at the same time, the Bank of England was restricted to issue new banknotes only if they were 100% backed by gold or up to £14 million in government debt

Roman Empire
–
Civil wars and executions continued, culminating in the victory of Octavian, Caesars adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavians power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power, the imperial period of Rome lasted approximately 1,500 years compared to the 500 years of the Republican era. The first two centuries of the empires existence were a period of unprecedented political stability and prosperity known as the Pax Romana, following Octavians victory, the size of the empire was dramatically increased. After the assassination of Caligula in 41, the senate briefly considered restoring the republic, under Claudius, the empire invaded Britannia, its first major expansion since Augustus. Vespasian emerged triumphant in 69, establishing the Flavian dynasty, before being succeeded by his son Titus and his short reign was followed by the long reign of his brother Domitian, who was eventually assassinated. The senate then appointed the first of the Five Good Emperors, the empire reached its greatest extent under Trajan, the second in this line. A period of increasing trouble and decline began with the reign of Commodus, Commodus assassination in 192 triggered the Year of the Five Emperors, of which Septimius Severus emerged victorious. The assassination of Alexander Severus in 235 led to the Crisis of the Third Century in which 26 men were declared emperor by the Roman Senate over a time span. It was not until the reign of Diocletian that the empire was fully stabilized with the introduction of the Tetrarchy, which saw four emperors rule the empire at once. This arrangement was unsuccessful, leading to a civil war that was finally ended by Constantine I. Constantine subsequently shifted the capital to Byzantium, which was renamed Constantinople in his honour and it remained the capital of the east until its demise. Constantine also adopted Christianity which later became the state religion of the empire. However, Augustulus was never recognized by his Eastern colleague, and separate rule in the Western part of the empire ceased to exist upon the death of Julius Nepos. The Eastern Roman Empire endured for another millennium, eventually falling to the Ottoman Turks in 1453, the Roman Empire was among the most powerful economic, cultural, political and military forces in the world of its time. It was one of the largest empires in world history, at its height under Trajan, it covered 5 million square kilometres. It held sway over an estimated 70 million people, at that time 21% of the entire population. Throughout the European medieval period, attempts were made to establish successors to the Roman Empire, including the Empire of Romania, a Crusader state. Rome had begun expanding shortly after the founding of the republic in the 6th century BC, then, it was an empire long before it had an emperor

Invasion of Algiers in 1830
–
The Invasion of Algiers in 1830 was a large-scale military operation by which the Kingdom of France, ruled by Charles X, invaded and conquered the Ottoman Regency of Algiers. Algiers had been a province of the Ottoman Empire since the Capture of Algiers in 1529 by Hayreddin Barbarossa, a diplomatic incident in 1827, the so-called Fan Affair served as a pretext to initiate a blockade against the port of Algiers. Charles X was also in need of diverting attention from turbulent French domestic affairs that culminated with his deposition during the stages of the invasion in the July Revolution. The invasion of Algiers began on 5 July 1830 with a bombardment by a fleet under Admiral Duperré. The French quickly defeated the troops of Hussein Dey, the Ottoman ruler and this resulted in a protracted military campaign, lasting more than 45 years, to root out popular opposition to the colonisation. The so-called pacification was marked by resistance of such as Ahmed Bey, Abd El-Kader. The invasion marked the end of several centuries of Ottoman rule in Algeria, in 1848, the territories conquered around Algiers were organised into three départements, defining the territories of modern Algeria. During the Napoleonic Wars, the Regency of Algiers had greatly benefited from trade in the Mediterranean, the Bourbon Restoration limited trading, while the Mediterranean was completely controlled by the British Royal Navy, and the rebuilding French Navy. This in turn led to the First Barbary War and the Second Barbary War, the wide unpopularity of the Bourbon Restoration also made France unstable. In an attempt to distract his people from domestic affairs, King Charles X decided to engage in a colonial policy. In 1827, Hussein Dey, Algerias Ottoman ruler, demanded that the French pay a 28-year-old debt, the French consul Pierre Deval refused to give answers satisfactory to the dey, and in an outburst of anger, Hussein Dey touched the consul with his fly-whisk. Charles X used this as an excuse to initiate a blockade against the port of Algiers. The blockade lasted for three years, and was primarily to the detriment of French merchants who were unable to do business with Algiers, while Barbary pirates were still able to evade the blockade. When France in 1829 sent an ambassador to the dey with a proposal for negotiations, the French then determined that more forceful action was required. King Charles X decided to organise an expedition on the coasts of Algiers to punish the impudence of the dey. The naval part of the operation was given to Admiral Duperré and he was nevertheless given command of the fleet. The land part was under the orders of Louis Auguste Victor de Ghaisne, on 16 May, a fleet comprising 103 warships and 464 transports departed Toulon, carrying a 37, 612-man strong army. The ground was well-known, thanks to observations made during the First Empire, the vanguard of the fleet arrived off Algiers on 31 May, but it took until 14 June for the entire fleet to arrive

Obverse and reverse
–
In this usage, obverse means the front face of the object and reverse means the back face. The obverse of a coin is commonly called heads, because it depicts the head of a prominent person. In fields of scholarship outside numismatics, the front is more commonly used than obverse. For prints and drawings with material on both sides the one judged as more significant will be the recto, a convention now exists typically to display the obverse to the left and the reverse to the right in photographs and museum displays, but this is not invariably observed. Following this principle, in the most famous of ancient Greek coins, the tetradrachm of Athens, the obverse is the head of Athena, similar versions of these two images, both symbols of the state, were used on the Athenian coins for more than two centuries. The opposite side may have varied from time to time and this change happened in the coinage of Alexander the Great, which continued to be minted long after his death. The various Hellenistic rulers who were his successors followed his tradition and this script alone style then was used on nearly all Islamic coinage until the modern period. The type of Justinian II was revived after the end of Iconoclasm, without images, therefore, it is not always easy to tell which side will be regarded as the obverse without some knowledge. After 695, Islamic coins avoided all images of persons and usually, the side expressing the Six Kalimas is usually defined as the obverse. The form of currency follows its function, which is to serve as an accepted medium of exchange of value. Traditionally, most states have been monarchies where the person of the monarch, if not provided for on the obverse, the reverse side usually contains information relating to a coins role as medium of exchange. Additional space typically reflects the countrys culture or government, or evokes some aspect of the states territory. Regarding the euro, some regarding the obverse and reverse of the euro coins exists. This rule does not apply to the coins as they dont have a common side. A number of the used for obverse national sides of euro coins were taken from the reverse of the old pre-euro coins of some individual countries. Several countries continue to use portraits of the monarch and the Republic of Ireland continues to use the State Arms. The Chrysanthemum Crest was no longer used after the war, and so, the side on which the date continues to be regarded as the reverse. Following ancient tradition, the obverse of coins of the United Kingdom almost always feature the head of the monarch

Eastern Arabic numerals
–
These numbers are known as أرقام هندية in Arabic. They are sometimes also called Indic numerals in English, however, that is sometimes discouraged as it can lead to confusion with Indian numerals, used in Brahmic scripts of India. Each numeral in the Persian variant has a different Unicode point even if it looks identical to the Eastern Arabic numeral counterpart, however the variants used with Urdu, Sindhi and other South Asian languages are not encoded separately from the Persian variants. See U+0660 through U+0669 and U+06F0 through U+06F9, written numerals are arranged with their lowest-value digit to the right, with higher value positions added to the left. That is identical to the arrangement used by Western texts using Hindu-Arabic numerals even though Arabic script is read from right to left. There is no conflict unless numerical layout is necessary, as is the case for arithmetic problems and lists of numbers, Eastern Arabic numerals remain strongly predominant vis-à-vis Western Arabic numerals in many countries to the East of the Arab world, particularly in Iran and Afghanistan. In Pakistan, Western Arabic numerals are more used as a considerable majority of the population is anglophone. Eastern numerals still continue to see use in Urdu publications and newspapers, in North Africa, only Western Arabic numerals are now commonly used. In medieval times, these used a slightly different set

Arecaceae
–
The Arecaceae are a botanical family of perennial climbers, shrubs, acaules and trees commonly known as palm trees. They are flowering plants, a family in the monocot order Arecales, currently 181 genera with around 2600 species are known, most of them restricted to tropical, subtropical, and warm temperate climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, however, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively cultivated plant families and they have been important to humans throughout much of history. Many common products and foods are derived from palms, and palms are widely used in landscaping, making them one of the most economically important plants. In many historical cultures, palms were symbols for such ideas as victory, peace, for inhabitants of cooler climates today, palms symbolize the tropics and vacations. Whether as shrubs, trees, or vines, palms have two methods of growth, solitary or clustered, the common representation is that of a solitary shoot ending in a crown of leaves. This monopodial character may be exhibited by prostrate, trunkless, some common palms restricted to solitary growth include Washingtonia and Roystonea. Palms may instead grow in sparse though dense clusters, the trunk develops an axillary bud at a leaf node, usually near the base, from which a new shoot emerges. The new shoot, in turn, produces an axillary bud, exclusively sympodial genera include many of the rattans, Guihaia, and Rhapis. Several palm genera have both solitary and clustering members, Palms which are usually solitary may grow in clusters, and vice versa. These aberrations suggest the habit operates on a single gene, Palms have large, evergreen leaves that are either palmately or pinnately compound and spirally arranged at the top of the stem. The leaves have a sheath at the base that usually splits open on one side at maturity. The inflorescence is a spadix or spike surrounded by one or more bracts or spathes that become woody at maturity, the flowers are generally small and white, radially symmetric, and can be either uni- or bisexual. The sepals and petals usually number three each, and may be distinct or joined at the base, the stamens generally number six, with filaments that may be separate, attached to each other, or attached to the pistil at the base. The fruit is usually a single-seeded drupe but some genera may contain two or more seeds in each fruit, like all monocots, palms do not have the ability to increase the width of a stem via the same kind of vascular cambium found in non-monocot woody plants. This explains the shape of the trunk that is often seen in palms. The Arecaceae are notable among monocots for their height and for the size of their seeds, leaves, Ceroxylon quindiuense, Colombias national tree, is the tallest monocot in the world, reaching up to 60 m tall

Cornucopia
–
In classical antiquity, the cornucopia or horn of plenty was a symbol of abundance and nourishment, commonly a large horn-shaped container overflowing with produce, flowers or nuts. Mythology offers multiple explanations of the origin of the cornucopia, one of the best-known involves the birth and nurturance of the infant Zeus, who had to be hidden from his devouring father Kronus. In a cave on Mount Ida on the island of Crete, baby Zeus was cared for and protected by a number of attendants, including the goat Amalthea. In another myth, the cornucopia was created when Heracles wrestled with the river god Achelous and wrenched off one of his horns and this version is represented in the Achelous and Hercules mural painting by the American Regionalist artist Thomas Hart Benton. In modern depictions, the cornucopia is typically a hollow, horn-shaped wicker basket filled with various kinds of festive fruit, in most of North America, the cornucopia has come to be associated with Thanksgiving and the harvest. Cornucopia is also the name of the annual November Food and Wine celebration in Whistler, British Columbia, two cornucopias are seen in the flag and state seal of Idaho. The Great Seal of North Carolina depicts Liberty standing and Plenty holding a cornucopia, the coat of arms of Colombia, Panama, Peru and Venezuela, and the Coat of Arms of the State of Victoria, Australia, also feature the cornucopia, symbolising prosperity. In the book and film series The Hunger Games, the Cornucopia is filled with weapons, and is the point of the Games. The horn of plenty is used for art and at Halloween, as it is a symbol of fertility, fortune

Sheep
–
The sheep is a quadrupedal, ruminant mammal typically kept as livestock. Like all ruminants, sheep are members of the order Artiodactyla, although the name sheep applies to many species in the genus Ovis, in everyday usage it almost always refers to Ovis aries. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female sheep is referred to as a ewe, a male as a ram or occasionally a tup, a castrated male as a wether. Sheep are most likely descended from the wild mouflon of Europe, one of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleece, meat and milk. A sheeps wool is the most widely used animal fiber, and is harvested by shearing. Ovine meat is called lamb when from younger animals and mutton when from older ones, Sheep continue to be important for wool and meat today, and are also occasionally raised for pelts, as dairy animals, or as model organisms for science. Sheep husbandry is practised throughout the majority of the inhabited world, in the modern era, Australia, New Zealand, the southern and central South American nations, and the British Isles are most closely associated with sheep production. Sheepraising has a lexicon of unique terms which vary considerably by region. Use of the sheep began in Middle English as a derivation of the Old English word scēap. A group of sheep is called a flock, herd or mob, many other specific terms for the various life stages of sheep exist, generally related to lambing, shearing, and age. Being a key animal in the history of farming, sheep have a deeply entrenched place in human culture, as livestock, sheep are most often associated with pastoral, Arcadian imagery. Sheep figure in many mythologies—such as the Golden Fleece—and major religions, in both ancient and modern religious ritual, sheep are used as sacrificial animals. Domestic sheep are relatively small ruminants, usually with a crimped hair called wool, domestic sheep differ from their wild relatives and ancestors in several respects, having become uniquely neotenic as a result of selective breeding by humans. A few primitive breeds of sheep retain some of the characteristics of their wild cousins, depending on breed, domestic sheep may have no horns at all, or horns in both sexes, or in males only. Most horned breeds have a pair, but a few breeds may have several. Another trait unique to domestic sheep as compared to wild ovines is their variation in color. Wild sheep are largely variations of brown hues, and variation within species is extremely limited, colors of domestic sheep range from pure white to dark chocolate brown, and even spotted or piebald

Tractor
–
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery used in agriculture or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially tillage, but nowadays a great variety of tasks. Agricultural implements may be towed behind or mounted on the tractor, the word tractor was taken from Latin, being the agent noun of trahere to pull. The first recorded use of the meaning an engine or vehicle for pulling wagons or ploughs occurred in 1901. In Canada and the USA, the word may refer to the road tractor portion of a tractor trailer truck. The first powered farm implements in the early 19th century were portable engines – steam engines on wheels that could be used to drive farm machinery by way of a flexible belt. Richard Trevithick designed the first semi-portable stationary steam engine for use, known as a barn engine in 1812. The truly portable engine was invented in 1839 by William Tuxford of Boston, a large flywheel was mounted on the crankshaft, and a stout leather belt was used to transfer the drive to the equipment being driven. In the 1850s, John Fowler used a Clayton & Shuttleworth portable engine to drive apparatus in the first public demonstrations of the application of cable haulage to cultivation. In parallel with the portable engine development, many engineers attempted to make them self-propelled – the fore-runners of the traction engine. In most cases this was achieved by fitting a sprocket on the end of the crankshaft and these experiments met with mixed success. The alteration was made by fitting a long driving chain between the crankshaft and the rear axle. The first half of the 1860s was a period of great experimentation but by the end of the decade the standard form of the engine had evolved. It was widely adopted for agricultural use, the first tractors were steam-powered plowing engines. They were used in pairs, placed on side of a field to haul a plow back. In Britain Manns and Garrett developed steam tractors for direct ploughing, in the United States, where soil conditions permitted, steam tractors were used to direct-haul plows. Steam-powered agricultural engines remained in use well into the 20th century until reliable internal combustion engines had been developed, in 1892, John Froelich invented and built the first gasoline/petrol-powered tractor in Clayton County, Iowa, USA. A Van Duzen single-cylinder gasoline engine was mounted on a Robinson engine chassis, after receiving a patent, Froelich started up the Waterloo Gasoline Engine Company and invested all of his assets

Wheat
–
Wheat is a cereal grain, originally from the Levant region but now cultivated worldwide. In 2016, world production of wheat was 749 million tonnes, making it the second most-produced cereal after maize, since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st Century. This grain is grown on land area than any other commercial food. World trade in wheat is greater than for all other crops combined, globally, wheat is the leading source of vegetal protein in human food, having a protein content of about 13%, which is relatively high compared to other major cereals and staple foods. The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. In a small part of the population, gluten – the major part of wheat protein – can trigger coeliac disease, non-coeliac gluten sensitivity, gluten ataxia. Cultivation and repeated harvesting and sowing of the grains of wild grasses led to the creation of domestic strains, in domesticated wheat, grains are larger, and the seeds remain attached to the ear by a toughened rachis during harvesting. In wild strains, a more fragile rachis allows the ear to easily shatter, as the traits that improve wheat as a food source also involve the loss of the plants natural seed dispersal mechanisms, highly domesticated strains of wheat cannot survive in the wild. Cultivation of wheat began to spread beyond the Fertile Crescent after about 8000 BCE, jared Diamond traces the spread of cultivated emmer wheat starting in the Fertile Crescent sometime before 8800 BCE. Archaeological analysis of wild emmer indicates that it was first cultivated in the southern Levant with finds dating back as far as 9600 BCE, Genetic analysis of wild einkorn wheat suggests that it was first grown in the Karacadag Mountains in southeastern Turkey. Dated archeological remains of wheat in settlement sites near this region, including those at Abu Hureyra in Syria. With the anomalous exception of two grains from Iraq ed-Dubb, the earliest carbon-14 date for einkorn wheat remains at Abu Hureyra is 7800 to 7500 years BCE. Remains of harvested emmer from several sites near the Karacadag Range have been dated to between 8600 and 8400 BCE, that is, in the Neolithic period and these remains were dated by Willem van Zeist and his assistant Johanna Bakker-Heeres to 8800 BCE. They also concluded that the settlers of Tell Aswad did not develop this form of emmer themselves, the cultivation of emmer reached Greece, Cyprus and India by 6500 BCE, Egypt shortly after 6000 BCE, and Germany and Spain by 5000 BCE. The early Egyptians were developers of bread and the use of the oven, by 3000 BCE, wheat had reached the British Isles and Scandinavia. A millennium later it reached China, the oldest evidence for hexaploid wheat has been confirmed through DNA analysis of wheat seeds, dating to around 6400-6200 BCE, recovered from Çatalhöyük. The first identifiable bread wheat with sufficient gluten for yeasted breads has been identified using DNA analysis in samples from a dating to approximately 1350 BCE at Assiros in Macedonia. From Asia, wheat continued to spread throughout Europe, in the British Isles, wheat straw was used for roofing in the Bronze Age, and was in common use until the late 19th century

Banknote
–
A banknote is a type of negotiable instrument known as a promissory note, made by a bank, payable to the bearer on demand. Banknotes were originally issued by banks, who were legally required to redeem the notes for legal tender when presented to the chief cashier of the originating bank. These commercial banknotes only traded at face value in the served by the issuing bank. Commercial banknotes have primarily been replaced by national banknotes issued by central banks, national banknotes are generally legal tender, meaning that medium of payment is allowed by law or recognized by a legal system to be valid for meeting a financial obligation. Historically, banks sought to ensure that they could always pay customers in coins when they presented banknotes for payment and this practice of backing notes with something of substance is the basis for the history of central banks backing their currencies in gold or silver. Today, most national currencies have no backing in precious metals or commodities and have value only by fiat, with the exception of non-circulating high-value or precious metal issues, coins are used for lower valued monetary units, while banknotes are used for higher values. The idea of using a durable light-weight substance as evidence of a promise to pay a bearer on demand originated in China during the Han Dynasty in 118 BC, the first known banknote was first developed in China during the Tang and Song dynasties, starting in the 7th century. Its roots were in merchant receipts of deposit during the Tang Dynasty, as merchants, during the Yuan Dynasty, banknotes were adopted by the Mongol Empire. In Europe, the concept of banknotes was first introduced during the 13th century by such as Marco Polo. Counterfeiting, the forgery of banknotes, is an inherent challenge in issuing currency and it is countered by anticounterfeiting measures in the printing of banknotes. Fighting the counterfeiting of banknotes and cheques has been a driver of security printing methods development in recent centuries. Paper currency first developed in the Tang Dynasty China during the 7th century, although true paper money did not appear until the 11th century, the usage of paper currency later spread throughout the Mongol Empire. European explorers like Marco Polo introduced the concept in Europe during the 13th century, napoleon issued paper banknotes in the early 1800s. Paper money originated in two forms, drafts, which are receipts for value held on account, and bills, the perception of banknotes as money has evolved over time. Originally, money was based on precious metals, Banknotes were seen as essentially an I. O. U. or promissory note, a promise to pay someone in precious metal on presentation. With the gradual removal of precious metals from the system, banknotes evolved to represent credit money. Notes or bills were referred to in 18th century novels and were often a key part of the plot such as a note drawn by Lord X for £100 which becomes due in 3 months time. Its roots were in merchant receipts of deposit during the Tang Dynasty, as merchants, before the use of paper, the Chinese used coins that were circular, with a rectangular hole in the middle
