110-560: The Addiator is composed of sheet-metal sliders inside a metal envelope, manipulated by a stylus, with an innovative carry mechanism, doing subtract ten, carry one with a simple stylus movement. Some types of Addiators can also handle negative numbers (with a complementary bottom window or by providing a subtraction mode on the back side of the device). The Addiator also handles non-decimal measurements, like feet and inches, or pre-decimalization pounds, shillings, and pence . Addition and subtraction require different "screens", handled by turning

220-405: A priestly role . He could not marry a woman from a senatorial family, nor achieve legitimate senatorial rank himself, but during the early Empire, freedmen held key positions in the government bureaucracy, so much so that Hadrian limited their participation by law. The rise of successful freedmen—through political influence or wealth—is a characteristic of early Imperial society. The prosperity of

330-443: A 1966 single titled "£.s.d." that highlighted the double entendre . The Chemical Defence Experimental Establishment called the first field trial with LSD as a chemical weapon "Moneybags" as a pun. The score of 26 at darts (one dart in each of the top three spaces) was sometimes called "half-a-crown" as late as the 1990s, though this did start to confuse the younger players. 26 is also referred to as "Breakfast", since 2/6 or half

440-462: A built-in slide rule on the back. Sometime between 1666 and 1675, French polymath Claude Perrault invented the first slide calculator, called Abaque rhabdologique (a rabdological abacus ), when he needed to do a lot of calculations while working as an architect . About three decades later, around 1700 or shortly after, French businessman and amateur mathematician César Caze simplified Perrault's design and adapted it to counting money, getting

550-589: A crown was the standard cost for breakfast pre-decimalisation. Roman Empire The Roman Empire was the era of Roman civilisation lasting from 27 BC to 476 AD. Rome ruled the Mediterranean and much of Europe, Western Asia and North Africa. The Romans conquered most of this during the Republic , and it was ruled by emperors following Octavian 's assumption of effective sole rule in 27 BC. The western empire collapsed in 476 AD, but

660-403: A decimal currency system based on the " as " whereby 1 denarius = 10 as . The silver denarius was the common circulation coin, but accounting was in sestercii . Later Roman Emperors undertook multiple coinage reforms, redefining weights and coins' relative values and introducing new coins and new accounting systems for them. Since most reforms were not even completed before the next one began,

770-535: A decimal system. Although the names originated from popular coins in the classical Roman Empire , their definitions and the ratios between them were introduced and imposed across Western Europe by the Emperor Charlemagne . King Offa of Mercia adopted the Frankish silver standard of librae, solidi and denarii into Britain in the late 8th century. The £sd system was the standard across much of

880-425: A fifth of the population and played a major role in the economy. Slavery was a complex institution that supported traditional Roman social structures as well as contributing economic utility. In urban settings, slaves might be professionals such as teachers, physicians, chefs, and accountants; the majority of slaves provided trained or unskilled labour. Agriculture and industry, such as milling and mining, relied on

990-640: A fine for a crime for which an humilior might receive a scourging . Execution, which was an infrequent legal penalty for free men under the Republic, could be quick and relatively painless for honestiores , while humiliores might suffer the kinds of torturous death previously reserved for slaves, such as crucifixion and condemnation to the beasts . In the early Empire, those who converted to Christianity could lose their standing as honestiores , especially if they declined to fulfil religious responsibilities, and thus became subject to punishments that created

1100-425: A freedman were born free, with full rights of citizenship. After manumission, a slave who had belonged to a Roman citizen enjoyed active political freedom ( libertas ), including the right to vote. His former master became his patron ( patronus ): the two continued to have customary and legal obligations to each other. A freedman was not entitled to hold public office or the highest state priesthoods, but could play

1210-629: A high-achieving group of freedmen is attested by inscriptions throughout the Empire . The Latin word ordo (plural ordines ) is translated variously and inexactly into English as "class, order, rank". One purpose of the Roman census was to determine the ordo to which an individual belonged. Two of the highest ordines in Rome were the senatorial and equestrian. Outside Rome, cities or colonies were led by decurions , also known as curiales . "Senator"

1320-571: A higher social class. Most of the emperors were bilingual but had a preference for Latin in the public sphere for political reasons, a "rule" that first started during the Punic Wars . Different emperors up until Justinian would attempt to require the use of Latin in various sections of the administration but there is no evidence that a linguistic imperialism existed during the early Empire. After all freeborn inhabitants were universally enfranchised in 212 , many Roman citizens would have lacked

1430-401: A household or workplace, a hierarchy of slaves might exist, with one slave acting as the master of others. Talented slaves might accumulate a large enough peculium to justify their freedom, or be manumitted for services rendered. Manumission had become frequent enough that in 2 BC a law ( Lex Fufia Caninia ) limited the number of slaves an owner was allowed to free in his will. Following

1540-409: A knowledge of Latin. The wide use of Koine Greek was what enabled the spread of Christianity and reflects its role as the lingua franca of the Mediterranean during the time of the Empire. Following Diocletian's reforms in the 3rd century CE, there was a decline in the knowledge of Greek in the west. Spoken Latin later fragmented into the incipient romance languages in the 7th century CE following

1650-522: A lasting influence on the development of language , religion , art , architecture , literature , philosophy , law , and forms of government across its territories. Latin evolved into the Romance languages while Medieval Greek became the language of the East. The Empire's adoption of Christianity resulted in the formation of medieval Christendom . Roman and Greek art had a profound impact on

1760-459: A man as an equestrian. The census of 28 BC uncovered large numbers of men who qualified, and in 14 AD, a thousand equestrians were registered at Cádiz and Padua alone. Equestrians rose through a military career track ( tres militiae ) to become highly placed prefects and procurators within the Imperial administration. The rise of provincial men to the senatorial and equestrian orders

1870-560: A married woman could have sex only with her husband, but a married man did not commit adultery if he had sex with a prostitute or person of marginalized status. Childbearing was encouraged: a woman who had given birth to three children was granted symbolic honours and greater legal freedom (the ius trium liberorum ). At the time of Augustus, as many as 35% of the people in Roman Italy were slaves, making Rome one of five historical "slave societies" in which slaves constituted at least

1980-574: A penny) were represented by the appropriate symbol ( 1 ⁄ 4 for farthing, 1 ⁄ 2 for halfpenny, or 3 ⁄ 4 for three farthings) after the whole pence. A convention frequently used in retail pricing was to list prices over one pound all in shillings, rather than in pounds and shillings; for example, £4-18-0 would be written as 98/– (£4.90 in decimal currency). This is still seen in shilling categories of Scottish beer , such as 90/– beer. Sometimes, prices of luxury goods and furniture were expressed by merchants in guineas , although

2090-464: A pound. Although the standard ledger accounting system recorded only pounds, shillings and pence, actual minted coins could represent one, several or fractions of these units. The penny was subdivided into 4 farthings until 31 December 1960, when they ceased to be legal tender in the UK, and until 31 July 1969 there was also a halfpenny ("HAYp'ny", /ˈheɪpni/) in circulation. The perceived advantage of such

2200-454: A privilege (patent) in 1711. However, neither of these devices implemented a carry mechanism. In 1845, German musician and amateur mechanic Heinrich Kummer, who was living in St. Petersburg, saw a mechanical calculator of a different design made by Hayyim Selig Slonimski , and in the next year borrowed the idea of its carry mechanism to greatly improve Caze's device, leading to the modern variant of

2310-427: A sense of "Romanness". Roman society had multiple, overlapping social hierarchies . The civil war preceding Augustus caused upheaval, but did not effect an immediate redistribution of wealth and social power. From the perspective of the lower classes, a peak was merely added to the social pyramid. Personal relationships— patronage , friendship ( amicitia ), family , marriage —continued to influence politics. By

2420-513: A slave's rapist had to be prosecuted by the owner for property damage under the Aquilian Law . Slaves had no right to the form of legal marriage called conubium , but their unions were sometimes recognized. Technically, a slave could not own property, but a slave who conducted business might be given access to an individual fund ( peculium ) that he could use, depending on the degree of trust and co-operation between owner and slave. Within

2530-462: A system was its use in some aspects of mental arithmetic , as it afforded many factors and hence fractions of a pound such as tenths, eighths, sixths and even sevenths and ninths if the guinea (worth 21 shillings) was used. When dealing with items in dozens, multiplication and division are straightforward; for example, if a dozen eggs cost four shillings, then each egg was priced at fourpence. Basic addition, however, could be more difficult than using

2640-630: Is a Germanic adaptation of the Latin phrase libra pondo 'a pound weight'. On the Iberian peninsula, the Kingdom of Aragon adopted the Carolingian monetary system (Catalan: lliura , sou and diners ), but those of Portugal and Castile (and subsequently Spain) retained the currency system inherited from al-Andalus . During the early Middle Ages, only the denarius was issued as an actual coin;

2750-545: Is an aspect of social mobility in the early Empire. Roman aristocracy was based on competition, and unlike later European nobility , a Roman family could not maintain its position merely through hereditary succession or having title to lands. Admission to the higher ordines brought distinction and privileges, but also responsibilities. In antiquity, a city depended on its leading citizens to fund public works, events, and services ( munera ). Maintaining one's rank required massive personal expenditures. Decurions were so vital for

2860-528: Is the popular name for the pre-decimal currencies once common throughout Europe. The abbreviation originates from the Latin currency denominations librae , solidi , and denarii . In the United Kingdom , these were referred to as pounds , shillings , and pence ( pence being the plural of penny ). Under this system, there were 12 pence in a shilling and 20 shillings, or 240 pence, in

2970-619: Is traditionally regarded as the Pax Romana ("Roman Peace"). The cohesion of the empire was furthered by a degree of social stability and economic prosperity that Rome had never before experienced. Uprisings in the provinces were infrequent and put down "mercilessly and swiftly". The success of Augustus in establishing principles of dynastic succession was limited by his outliving a number of talented potential heirs. The Julio-Claudian dynasty lasted for four more emperors— Tiberius , Caligula , Claudius , and Nero —before it yielded in 69 AD to

3080-601: The Harry Potter books is a parody of the £sd system, with 29 knuts to a sickle and 17 sickles to a galleon. It serves as the currency of the Wizarding World, while pounds are still used by Muggles, the non-magical people. Lysergic acid diethylamide was sometimes called "pounds, shillings and pence" during the 1960s, because of the abbreviation LSD. The English rock group the Pretty Things released

3190-403: The 1,000 Guineas and 2,000 Guineas at Newmarket Racecourse . South Africa and Southern Rhodesia : tickey. Australia: "deener" is likely to have derived from the Latin "dinar" or "denarius". UK: "Thick 'un" because it was thicker than a shilling. Australia: Fiddly-did was derived from word association (fiddly → fid → quid). The currency of knuts, sickles and galleons in

3300-604: The Battle of Actium in 31 BC. In 27 BC the Senate gave him the title Augustus ("venerated") and made him princeps ("foremost") with proconsular imperium , thus beginning the Principate , the first epoch of Roman imperial history. Although the republic stood in name, Augustus had all meaningful authority. During his 40-year rule, a new constitutional order emerged so that, upon his death, Tiberius would succeed him as

3410-475: The Dominate . The emperor was the ultimate authority in policy- and decision-making, but in the early Principate, he was expected to be accessible and deal personally with official business and petitions. A bureaucracy formed around him only gradually. The Julio-Claudian emperors relied on an informal body of advisors that included not only senators and equestrians, but trusted slaves and freedmen. After Nero,

3520-694: The Huns of Attila , led to the decline of the Western Roman Empire . With the fall of Ravenna to the Germanic Herulians and the deposition of Romulus Augustus in 476 by Odoacer , the Western Empire finally collapsed. The Eastern Roman Empire survived for another millennium with Constantinople as its sole capital, until the city's fall in 1453. Due to the Empire's extent and endurance, its institutions and culture had

3630-552: The Italian Renaissance . Rome's architectural tradition served as the basis for Romanesque , Renaissance and Neoclassical architecture , influencing Islamic architecture . The rediscovery of classical science and technology (which formed the basis for Islamic science ) in medieval Europe contributed to the Scientific Renaissance and Scientific Revolution . Many modern legal systems, such as

3740-718: The Napoleonic Code , descend from Roman law. Rome's republican institutions have influenced the Italian city-state republics of the medieval period, the early United States , and modern democratic republics . Rome had begun expanding shortly after the founding of the Roman Republic in the 6th century BC, though not outside the Italian Peninsula until the 3rd century BC. Thus, it was an "empire" (a great power) long before it had an emperor. The Republic

3850-618: The Napoleonic wars . By the mid-19th century, most of continental Europe had decimalised, leaving the United Kingdom as the only major country to continue to maintain the £sd system. All countries and territories that formerly used the £sd system have now decimalised their currency, with most decimalisations occurring after the Second World War . Malta decimalised its currency in 1972, while Nigeria decimalised in 1973. The British pound sterling and Irish pound were among

3960-586: The Nile Valley in Egypt. The empire completely circled the Mediterranean  ... referred to by its conquerors as mare nostrum —'our sea'. Trajan's successor Hadrian adopted a policy of maintaining rather than expanding the empire. Borders ( fines ) were marked, and the frontiers ( limites ) patrolled. The most heavily fortified borders were the most unstable. Hadrian's Wall , which separated

4070-478: The Roman Senate granted Octavian overarching military power ( imperium ) and the new title of Augustus , marking his accession as the first Roman emperor . The vast Roman territories were organized into senatorial provinces, governed by proconsuls who were appointed by lot annually, and imperial provinces, which belonged to the emperor but were governed by legates . The first two centuries of

4180-596: The Servile Wars of the Republic, legislation under Augustus and his successors shows a driving concern for controlling the threat of rebellions through limiting the size of work groups, and for hunting down fugitive slaves. Over time slaves gained increased legal protection, including the right to file complaints against their masters. A bill of sale might contain a clause stipulating that the slave could not be employed for prostitution, as prostitutes in ancient Rome were often slaves. The burgeoning trade in eunuchs in

4290-507: The eastern empire lasted until the fall of Constantinople in 1453. By 100 BC, Rome had expanded its rule to most of the Mediterranean and beyond. However, it was severely destabilised by civil wars and political conflicts , which culminated in the victory of Octavian over Mark Antony and Cleopatra at the Battle of Actium in 31 BC, and the subsequent conquest of the Ptolemaic Kingdom in Egypt. In 27 BC,

4400-698: The "mark of account" system lingered on in North Sea trade and areas of Hanseatic influence through much of the Middle Ages. Charlemagne's new monetary system prevailed across much of Western Europe including France (where the units were known as the livre , sous and denier ), Italy ( lira , soldo and denaro ), the Holy Roman Empire ( pfund , schilling and pfennig ) and in England ( pound , shilling and penny ). The English name pound

The IBM 1401 is one such machine; on Sterling models with £sd support, it had a switch for selecting between IBM and BSI data layouts of £sd on its auxiliary console (see image). The ICT 1301 and the PL/I language also had £sd support. There were several ways to represent amounts of money in writing and speech, with no formal convention; for example: Halfpennies and farthings (quarter of

4620-538: The 1960s and 1970s, with Nigeria being the last to abandon it in the form of the Nigerian pound on 1 January 1973. Historically, similar systems based on Roman coinage were used elsewhere; e.g., the division of the livre tournois in France and other pre-decimal currencies such as Spain , which had 20 maravedís to 1 real and 20 reales to 1 duro or 5 pesetas . The classical Roman Empire originally used

4730-566: The 600-member body by appointment. A senator's son belonged to the ordo senatorius , but he had to qualify on his own merits for admission to the Senate. A senator could be removed for violating moral standards. In the time of Nero, senators were still primarily from Italy , with some from the Iberian peninsula and southern France; men from the Greek-speaking provinces of the East began to be added under Vespasian. The first senator from

4840-400: The 6th and 7th centuries with the disintegration of the complex Imperial economy. Laws pertaining to slavery were "extremely intricate". Slaves were considered property and had no legal personhood . They could be subjected to forms of corporal punishment not normally exercised on citizens, sexual exploitation , torture, and summary execution . A slave could not as a matter of law be raped;

4950-457: The Augustan programme to restore traditional morality and social order, moral legislation attempted to regulate conduct as a means of promoting " family values ". Adultery was criminalized, and defined broadly as an illicit sex act ( stuprum ) between a male citizen and a married woman, or between a married woman and any man other than her husband. That is, a double standard was in place:

5060-644: The Bank of England. The last £sd coins to cease being legal tender in the UK after Decimal Day were the sixpence (withdrawn 1980), the shilling (withdrawn 1991) and the florin (withdrawn 1993). Commemorative crowns minted post decimalisation (worth either 25p or £5) are still legal tender, but are rarely, if ever, spent. The last £sd banknote to cease to be legal tender anywhere was the Isle of Man ten shilling note, which ceased to be legal tender there in 2013. Computers and calculators sold pre-decimalisation – mostly in

5170-577: The Empire saw a period of unprecedented stability and prosperity known as the Pax Romana ( lit.   ' Roman Peace ' ). Rome reached its greatest territorial extent under Trajan ( r.  98–117 AD ), but a period of increasing trouble and decline began under Commodus ( r.  180–192 ). In the 3rd century, the Empire underwent a 49-year crisis that threatened its existence due to civil war, plagues and barbarian invasions . The Gallic and Palmyrene empires broke away from

5280-524: The Empire was engulfed by the Crisis of the Third Century , a period of invasions , civil strife , economic disorder , and plague . In defining historical epochs , this crisis sometimes marks the transition from Classical to Late Antiquity . Aurelian ( r.  270–275 ) stabilised the empire militarily and Diocletian reorganised and restored much of it in 285. Diocletian's reign brought

5390-553: The European continent for over a thousand years, until the decimalisations of the 18th and 19th centuries. The United Kingdom remained one of the few countries retaining it into the 20th century, resulting in the system becoming particularly associated with Britain. For much of the 20th century, £sd remained the monetary system of most of the British Commonwealth , the major exceptions being Canada and India , until

5500-635: The Half-penny scheme, the Alb scheme, etc. – but all were determined to have deficiencies, and transition would be too difficult and expensive. The £sd system was maintained in Britain until 1971. As countries of the British Empire became independent, some abandoned the £sd system quickly, while others retained it almost as long as the UK itself. The United States of America was among the first to drop

5610-612: The Middle East. The Latin phrase imperium sine fine ("empire without end" ) expressed the ideology that neither time nor space limited the Empire. In Virgil 's Aeneid , limitless empire is said to be granted to the Romans by Jupiter . This claim of universal dominion was renewed when the Empire came under Christian rule in the 4th century. In addition to annexing large regions, the Romans directly altered their geography, for example cutting down entire forests . Roman expansion

5720-454: The Rhine and Danube. Roman jurists also show a concern for local languages such as Punic , Gaulish , and Aramaic in assuring the correct understanding of laws and oaths. In Africa , Libyco-Berber and Punic were used in inscriptions into the 2nd century. In Syria , Palmyrene soldiers used their dialect of Aramaic for inscriptions, an exception to the rule that Latin was the language of

5830-617: The Roman Republic ) while greatly extending its power beyond Italy. In 44 BC Julius Caesar was briefly perpetual dictator before being assassinated by a faction that opposed his concentration of power. This faction was driven from Rome and defeated at the Battle of Philippi in 42 BC by Mark Antony and Caesar's adopted son Octavian . Antony and Octavian divided the Roman world between them, but this did not last long. Octavian's forces defeated those of Mark Antony and Cleopatra at

5940-430: The Roman legal concept of imperium , meaning "command" (typically in a military sense). Occasionally, successful consuls or generals were given the honorary title imperator (commander); this is the origin of the word emperor , since this title was always bestowed to the early emperors. Rome suffered a long series of internal conflicts, conspiracies, and civil wars from the late second century BC (see Crisis of

6050-448: The Roman world from what was perceived as an ever-present barbarian threat, is the primary surviving monument of this effort. Latin and Greek were the main languages of the Empire, but the Empire was deliberately multilingual. Andrew Wallace-Hadrill says "The main desire of the Roman government was to make itself understood". At the start of the Empire, knowledge of Greek was useful to pass as educated nobility and knowledge of Latin

6160-458: The UK did. The UK abandoned the old penny on Decimal Day , 15 February 1971, when one pound sterling became divided into 100 new pence . This was a change from the system used in the earlier wave of decimalisations in Australia, New Zealand , Rhodesia and South Africa , in which the pound was replaced with a new major currency called either the "dollar" or the "rand". The British shilling

6270-449: The UK, larger denomination notes (£5, £10, £20, £50, £100, £200, £500, and £1,000) printed from the 18th century to 1943 were called "white notes" because they were printed on lightweight white paper (on one side only) in black ink. United Kingdom pre-decimal banknotes are no longer legal tender, but are exchangeable for their face value (regardless of the possible greater worth if sold or auctioned) if they are taken directly (or posted) to

6380-449: The account of his achievements ( Res Gestae ) prominently featured the geographical cataloguing of the Empire. Geography alongside meticulous written records were central concerns of Roman Imperial administration . The Empire reached its largest expanse under Trajan ( r.  98–117 ), encompassing 5 million km . The traditional population estimate of 55–60 million inhabitants accounted for between one-sixth and one-fourth of

6490-418: The collapse of the Empire's west. The dominance of Latin and Greek among the literate elite obscure the continuity of other spoken languages within the Empire. Latin, referred to in its spoken form as Vulgar Latin , gradually replaced Celtic and Italic languages . References to interpreters indicate the continuing use of local languages, particularly in Egypt with Coptic , and in military settings along

6600-546: The commission was the same number of shillings. Tattersalls , the main auctioneer of racehorses in the United Kingdom and Ireland, continues this tradition of conducting auctions in guineas at its UK sales (in Ireland, auctions are conducted in euros). The vendor's commission is 5%. The word "guineas" is still found in the names of some British horse races, even though their prize funds are now fixed in pounds – such as

6710-482: The conditions of martyrdom . The three major elements of the Imperial state were the central government, the military, and the provincial government. The military established control of a territory through war, but after a city or people was brought under treaty, the mission turned to policing: protecting Roman citizens, agricultural fields, and religious sites. The Romans lacked sufficient manpower or resources to rule through force alone. Cooperation with local elites

#1732787445713

6820-538: The continental example. A parliamentary select committee was set up in 1821 to inquire into decimalisation, but ended up recommending retaining the £sd system. However, pressure groups were formed inside Britain advocating the adoption of decimalisation of the currency, and Parliament returned to the matter in the 1850s. Various decimalisation schemes were considered – the Pound-and-Mil scheme, the Farthing scheme,

6930-481: The deceased emperor's deification. The dominance of the emperor was based on the consolidation of powers from several republican offices. The emperor made himself the central religious authority as pontifex maximus , and centralized the right to declare war, ratify treaties, and negotiate with foreign leaders. While these functions were clearly defined during the Principate , the emperor's powers over time became less constitutional and more monarchical, culminating in

7040-501: The descent "from a kingdom of gold to one of rust and iron", a comment which has led some historians, notably Edward Gibbon , to take Commodus' reign as the beginning of the Empire's decline . In 212, during the reign of Caracalla , Roman citizenship was granted to all freeborn inhabitants of the empire. The Severan dynasty was tumultuous; an emperor's reign was ended routinely by his murder or execution and, following its collapse,

7150-472: The easternmost province, Cappadocia , was admitted under Marcus Aurelius. By the Severan dynasty (193–235), Italians made up less than half the Senate. During the 3rd century, domicile at Rome became impractical, and inscriptions attest to senators who were active in politics and munificence in their homeland ( patria ). Senators were the traditional governing class who rose through the cursus honorum ,

7260-514: The empire's most concerted effort against the perceived threat of Christianity , the " Great Persecution ". Diocletian divided the empire into four regions, each ruled by a separate tetrarch . Confident that he fixed the disorder plaguing Rome, he abdicated along with his co-emperor, but the Tetrarchy collapsed shortly after . Order was eventually restored by Constantine the Great , who became

7370-506: The empire. This legal egalitarianism required a far-reaching revision of existing laws that distinguished between citizens and non-citizens. Freeborn Roman women were considered citizens, but did not vote, hold political office, or serve in the military. A mother's citizen status determined that of her children, as indicated by the phrase ex duobus civibus Romanis natos ("children born of two Roman citizens"). A Roman woman kept her own family name ( nomen ) for life. Children most often took

7480-631: The end of the Western Roman Empire in 476, when Romulus Augustulus was forced to abdicate to the Germanic warlord Odoacer . Odoacer ended the Western Empire by declaring Zeno sole emperor and placing himself as Zeno's nominal subordinate. In reality, Italy was ruled by Odoacer alone. The Eastern Roman Empire, called the Byzantine Empire by later historians, continued until the reign of Constantine XI Palaiologos ,

7590-504: The exploitation of slaves. Outside Italy, slaves were on average an estimated 10 to 20% of the population, sparse in Roman Egypt but more concentrated in some Greek areas. Expanding Roman ownership of arable land and industries affected preexisting practices of slavery in the provinces. Although slavery has often been regarded as waning in the 3rd and 4th centuries, it remained an integral part of Roman society until gradually ceasing in

7700-457: The father's name, with some exceptions. Women could own property, enter contracts, and engage in business. Inscriptions throughout the Empire honour women as benefactors in funding public works, an indication they could hold considerable fortunes. The archaic manus marriage in which the woman was subject to her husband's authority was largely abandoned by the Imperial era, and a married woman retained ownership of any property she brought into

7810-640: The first emperor to convert to Christianity , and who established Constantinople as the new capital of the Eastern Empire. During the decades of the Constantinian and Valentinian dynasties, the empire was divided along an east–west axis, with dual power centres in Constantinople and Rome. Julian , who under the influence of his adviser Mardonius attempted to restore Classical Roman and Hellenistic religion , only briefly interrupted

7920-456: The functioning of cities that in the later Empire, as the ranks of the town councils became depleted, those who had risen to the Senate were encouraged to return to their hometowns, in an effort to sustain civic life. In the later Empire, the dignitas ("worth, esteem") that attended on senatorial or equestrian rank was refined further with titles such as vir illustris ("illustrious man"). The appellation clarissimus (Greek lamprotatos )

8030-421: The guinea coin had not been struck since 1799. A guinea was 21 shillings (£1.05 in decimal currency). Professionals such as lawyers and physicians, art dealers, and some others stated their fees in guineas rather than pounds, while, for example, salaries were stated in pounds per annum. Historically, at some auctions, the purchaser would bid and pay in guineas but the seller would receive the same number of pounds;

8140-692: The historian Christopher Kelly described it: Then the empire stretched from Hadrian's Wall in drizzle-soaked northern England to the sun-baked banks of the Euphrates in Syria; from the great Rhine – Danube river system, which snaked across the fertile, flat lands of Europe from the Low Countries to the Black Sea , to the rich plains of the North African coast and the luxuriant gash of

Although not always advertised (e.g., the Magic Brain Calculator mentions "add, subtract, multiply" on its front plate), procedures exist for multiplication (by repeated addition or by individual digit multiplications) and division (e.g., by repeated subtraction, or use of additions combined with complementary numbers ). More expensive versions have

8360-521: The last Roman emperor. He died in battle in 1453 against Mehmed II and his Ottoman forces during the siege of Constantinople . Mehmed II adopted the title of caesar in an attempt to claim a connection to the former Empire. His claim was soon recognized by the Patriarchate of Constantinople , but not by most European monarchs. The Roman Empire was one of the largest in history, with contiguous territories throughout Europe, North Africa, and

8470-420: The last to be decimalised, on 15 February 1971 . In places where £sd was used, there were several approaches to decimalisation: The following table shows the conversion of common denominations of coins of the £sd systems. The following coins were not in common circulation in the UK at the time of decimalisation, though the ten shilling note and the pound note were. The farthing , at 1 ⁄ 4 penny,

8580-592: The late 1st century prompted legislation that prohibited the castration of a slave against his will "for lust or gain". Roman slavery was not based on race . Generally, slaves in Italy were indigenous Italians, with a minority of foreigners (including both slaves and freedmen) estimated at 5% of the total in the capital at its peak, where their number was largest. Foreign slaves had higher mortality and lower birth rates than natives, and were sometimes even subjected to mass expulsions. The average recorded age at death for

8690-553: The late 8th century, King Offa of Mercia imported the system into Britain to facilitate transactions (notably " Peter's pence ") with the Roman Catholic Church (which used the Carolingian coinage system). But it was not the sole system in Britain – the £sd system would have to compete for a while with the Viking " mark " accounting system, introduced into Danelaw regions. Although £sd ultimately prevailed in Britain,

8800-418: The late Roman Empire had a veritable mess of multiple overlapping systems of weights and currencies. Around the 780s, the Frankish emperor Charlemagne cut through the mess by creating a new uniform system. He defined the "libra" as a new measure of weight equivalent to around 408 grams (substantially larger than the old Roman pound of 328.9g), and ordered 240 silver units known as denarii to be struck from

8910-458: The libra and solidus were merely units of account. But over time, the silver resources were gradually exhausted and the coins became repeatedly debased by mediaeval monarchs, prompting the minting of larger coins from the 13th century. It also led to specification of currencies by mint of origin in contracts and accounting (e.g. a denier parisis , of the Paris mint, contained more actual silver than

9020-486: The marriage. Technically she remained under her father's legal authority, even though she moved into her husband's home, but when her father died she became legally emancipated. This arrangement was a factor in the degree of independence Roman women enjoyed compared to many other cultures up to the modern period: although she had to answer to her father in legal matters, she was free of his direct scrutiny in daily life, and her husband had no legal power over her. Although it

9130-416: The members of the three higher "orders", along with certain military officers. The granting of universal citizenship in 212 seems to have increased the competitive urge among the upper classes to have their superiority affirmed, particularly within the justice system. Sentencing depended on the judgment of the presiding official as to the relative "worth" ( dignitas ) of the defendant: an honestior could pay

9240-730: The military. The last reference to Gaulish was between 560 and 575. The emergent Gallo-Romance languages would then be shaped by Gaulish. Proto-Basque or Aquitanian evolved with Latin loan words to modern Basque . The Thracian language , as were several now-extinct languages in Anatolia, are attested in Imperial-era inscriptions. The Empire was remarkably multicultural, with "astonishing cohesive capacity" to create shared identity while encompassing diverse peoples. Public monuments and communal spaces open to all—such as forums , amphitheatres , racetracks and baths —helped foster

9350-444: The new de facto monarch. As Roman provinces were being established throughout the Mediterranean, Italy maintained a special status which made it domina provinciarum ("ruler of the provinces"), and – especially in relation to the first centuries of imperial stability – rectrix mundi ("governor of the world") and omnium terrarum parens ("parent of all lands"). The 200 years that began with Augustus's rule

9460-489: The new Carolingian pound of pure silver, each denarius containing 22.5 grains of silver. To help accounting, Charlemagne also decreed that the pound was divisible into 20 solidi each of 12 denarii . Thus began the Carolingian monetary system (1 l . = 20 s . = 240 d .). The new coinage and accounting system was imposed uniformly across the vast Carolingian Empire and also infiltrated countries on its periphery. In

9570-412: The political career track, but equestrians often possessed greater wealth and political power. Membership in the equestrian order was based on property; in Rome's early days, equites or knights had been distinguished by their ability to serve as mounted warriors, but cavalry service was a separate function in the Empire. A census valuation of 400,000 sesterces and three generations of free birth qualified

9680-507: The poor were other sources. Vernae , by contrast, were "homegrown" slaves born to female slaves within the household, estate or farm. Although they had no special legal status, an owner who mistreated or failed to care for his vernae faced social disapproval, as they were considered part of the family household and in some cases might actually be the children of free males in the family. Rome differed from Greek city-states in allowing freed slaves to become citizens; any future children of

9790-528: The slaves of the city of Rome was seventeen and a half years (17.2 for males; 17.9 for females). During the period of republican expansionism when slavery had become pervasive, war captives were a main source of slaves. The range of ethnicities among slaves to some extent reflected that of the armies Rome defeated in war, and the conquest of Greece brought a number of highly skilled and educated slaves. Slaves were also traded in markets and sometimes sold by pirates . Infant abandonment and self-enslavement among

9900-776: The slide calculator. In 1889, Louis-Joseph Troncet successfully commercialized the Addiator, which became one of the most popular calculators of its kind, and the name is often used to refer to the type generally. Addiators appeared in newspaper advertisements as early as 1921, listed at a price of £4 (equivalent to £224.15 in 2023) in the Daily Record of Scotland. As of 1968, Addiators were advertised in American newspapers starting at $ 3.98 each ($ 35.00 in 2023). Pounds, shillings, and pence £sd (occasionally written Lsd ), spoken as " pounds, shillings and pence ",

10010-646: The state and a series of short-lived emperors led the Empire, which was later reunified under Aurelian ( r.  270–275 ). The civil wars ended with the victory of Diocletian ( r.  284–305 ), who set up two different imperial courts in the Greek East and Latin West . Constantine the Great ( r.  306–337 ), the first Christian emperor , moved the imperial seat from Rome to Byzantium in 330, and renamed it Constantinople . The Migration Period , involving large invasions by Germanic peoples and by

10120-529: The strife-torn Year of the Four Emperors , from which Vespasian emerged as the victor. Vespasian became the founder of the brief Flavian dynasty , followed by the Nerva–Antonine dynasty which produced the " Five Good Emperors ": Nerva , Trajan , Hadrian , Antoninus Pius , and Marcus Aurelius . In the view of contemporary Greek historian Cassius Dio , the accession of Commodus in 180 marked

10230-461: The succession of Christian emperors. Theodosius I , the last emperor to rule over both East and West, died in 395 after making Christianity the state religion . The Western Roman Empire began to disintegrate in the early 5th century. The Romans fought off all invaders, most famously Attila , but the empire had assimilated so many Germanic peoples of dubious loyalty to Rome that the empire started to dismember itself. Most chronologies place

10340-562: The time of Nero , however, it was not unusual to find a former slave who was richer than a freeborn citizen, or an equestrian who exercised greater power than a senator. The blurring of the Republic's more rigid hierarchies led to increased social mobility , both upward and downward, to a greater extent than all other well-documented ancient societies. Women, freedmen, and slaves had opportunities to profit and exercise influence in ways previously less available to them. Social life, particularly for those whose personal resources were limited,

10450-409: The variety of new coins of various multiples and qualities led to common expression of quantities in terms of number of coins (guineas, crowns, farthings, etc.) But they would all have to be converted into formal £sd units in accounts. The £sd system continued in much of Western Europe for nearly a thousand years, until the " decimalisations " of the 18th and 19th centuries. Britain considered following

10560-452: The very debased denier tournois of the Tours mint). To facilitate larger transactions, gold coins began to be minted in western Europe around the same time. The French " franc ", introduced in 1360, was the first coin anywhere to represent exactly £1 and the gold " sovereign ", first minted in 1489, was the first English £1 coin. Although the £sd system remained intact in ledger accounting,

10670-411: The world's total population and made it the most populous unified political entity in the West until the mid-19th century. Recent demographic studies have argued for a population peak from 70 million to more than 100 million . Each of the three largest cities in the Empire – Rome, Alexandria , and Antioch – was almost twice the size of any European city at the beginning of the 17th century. As

10780-405: The £sd system and adopt a decimal currency in 1792, 10 years after independence from the British Empire, but retains many other aspects of the customary units for length and weight. Australia, on the other hand, only changed to using a decimal currency on 14 February 1966, 65 years after independence. New Zealand followed suit on 10 July 1967. Still others, notably Ireland , decimalised only when

10890-442: Was a point of pride to be a "one-man woman" ( univira ) who had married only once, there was little stigma attached to divorce , nor to speedy remarriage after being widowed or divorced. Girls had equal inheritance rights with boys if their father died without leaving a will. A mother's right to own and dispose of property, including setting the terms of her will, gave her enormous influence over her sons into adulthood. As part of

11000-475: Was further defined by their citizenship. Most citizens held limited rights (such as the ius Latinum , "Latin right"), but were entitled to legal protections and privileges not enjoyed by non-citizens. Free people not considered citizens, but living within the Roman world, were peregrini , non-Romans. In 212, the Constitutio Antoniniana extended citizenship to all freeborn inhabitants of

11110-466: Was further fostered by a proliferation of voluntary associations and confraternities ( collegia and sodalitates ): professional and trade guilds, veterans' groups, religious sodalities, drinking and dining clubs, performing troupes, and burial societies . According to the jurist Gaius , the essential distinction in the Roman " law of persons " was that all humans were either free ( liberi ) or slaves ( servi ). The legal status of free persons

11220-548: Was mostly accomplished under the Republic , though parts of northern Europe were conquered in the 1st century, when Roman control in Europe, Africa, and Asia was strengthened. Under Augustus , a "global map of the known world" was displayed for the first time in public at Rome, coinciding with the creation of the most comprehensive political geography that survives from antiquity, the Geography of Strabo . When Augustus died,

11330-671: Was necessary to maintain order, collect information, and extract revenue. The Romans often exploited internal political divisions. Communities with demonstrated loyalty to Rome retained their own laws, could collect their own taxes locally, and in exceptional cases were exempt from Roman taxation. Legal privileges and relative independence incentivized compliance. Roman government was thus limited , but efficient in its use of available resources. The Imperial cult of ancient Rome identified emperors and some members of their families with divinely sanctioned authority ( auctoritas ). The rite of apotheosis (also called consecratio ) signified

11440-416: Was never a legal requirement for Latin in the Empire, but it represented a certain status. High standards of Latin, Latinitas , started with the advent of Latin literature. Due to the flexible language policy of the Empire, a natural competition of language emerged that spurred Latinitas , to defend Latin against the stronger cultural influence of Greek. Over time Latin usage was used to project power and

11550-406: Was never converted, as it ceased to be legal tender a decade prior to decimalisation. In 1971, a new penny would have been worth 9.6 farthings (making a farthing slightly more than 0.1 new pence). Similarly, the old halfpenny and the half-crown were not converted in the UK either, having been withdrawn in the run-up to decimalisation, although the half-crown was worth exactly 12 1/2 new pence. In

11660-445: Was not a nation-state in the modern sense, but a network of self-ruled towns (with varying degrees of independence from the Senate ) and provinces administered by military commanders. It was governed by annually elected magistrates ( Roman consuls above all) in conjunction with the Senate. The 1st century BC was a time of political and military upheaval, which ultimately led to rule by emperors. The consuls' military power rested in

11770-426: Was not itself an elected office in ancient Rome; an individual gained admission to the Senate after he had been elected to and served at least one term as an executive magistrate . A senator also had to meet a minimum property requirement of 1 million sestertii . Not all men who qualified for the ordo senatorius chose to take a Senate seat, which required legal domicile at Rome. Emperors often filled vacancies in

11880-565: Was replaced by a 5 new pence coin worth one-twentieth of a pound. In Europe, decimalisation of currency (as well as other weights and measures) began in Revolutionary France with the law of 1795 ("Loi du 18 germinal an III", 7 April 1795), replacing the £sd accounting system of the Ancien régime with a system of 1 franc = 10 decimes = 100 centimes. Decimalisation was carried by French armies to neighboring European countries during

11990-447: Was used to designate the dignitas of certain senators and their immediate family, including women. "Grades" of equestrian status proliferated. As the republican principle of citizens' equality under the law faded, the symbolic and social privileges of the upper classes led to an informal division of Roman society into those who had acquired greater honours ( honestiores ) and humbler folk ( humiliores ). In general, honestiores were

12100-476: Was useful for a career in the military, government, or law. Bilingual inscriptions indicate the everyday interpenetration of the two languages. Latin and Greek's mutual linguistic and cultural influence is a complex topic. Latin words incorporated into Greek were very common by the early imperial era, especially for military, administration, and trade and commerce matters. Greek grammar, literature, poetry and philosophy shaped Latin language and culture. There
