Sunspot
–
Sunspots are temporary phenomena on the photosphere of the Sun that appear as dark spots compared with surrounding regions. They are areas of reduced surface temperature caused by concentrations of field flux that inhibit convection. Sunspots usually appear in pairs of magnetic polarity. Their number varies according to the approximately 11-year solar cycle, individual sunspots may endure anywhere from a few days to a few months, but eventually decay. Sunspots expand and contract as they move across the surface of the Sun with sizes ranging from 16 kilometers to 160,000 kilometers in diameter, the larger variety are visible from Earth without the aid of a telescope. They may travel at speeds, or proper motions of a few hundred meters per second when they first emerge. Indicating intense magnetic activity, sunspots accompany secondary phenomena such as coronal loops, most solar flares and coronal mass ejections originate in magnetically active regions around visible sunspot groupings. Similar phenomena indirectly observed on other than the sun are commonly called starspots. Although they are at temperatures of roughly 3, 000–4,500 K, isolated from the surrounding photosphere a sunspot would be brighter than the Moon. If the stress on the tubes reaches a limit, they curl up. Convection is inhibited at the points, the energy flux from the Suns interior decreases. The Wilson effect implies that sunspots are depressions on the Suns surface, observations using the Zeeman effect show that prototypical sunspots come in pairs with opposite magnetic polarity. From cycle to cycle, the polarities of leading and trailing sunspots change from north/south to south/north, magnetic pressure should tend to remove field concentrations, causing the sunspots to disperse, but sunspot lifetimes are measured in days to weeks. Sunspot activity cycles about every eleven years, the point of highest sunspot activity during a cycle is known as solar maximum, and the point of lowest activity as solar minimum. This period is observed in most other solar activity and is linked to a variation in the solar magnetic field that changes polarity with this period. Early in the cycle, sunspots appear in the latitudes and then move towards the equator as the cycle approaches maximum. Spots from two adjacent cycles can co-exist for some time, spots from adjacent cycles can be distinguished by direction of their magnetic field. The Wolf number sunspot index counts the number of sunspots

Science and technology of the Han dynasty
–
There were great innovations in metallurgy. Smelting techniques were enhanced with inventions such as the waterwheel-powered bellows, the quality of life was improved with many Han inventions. The Han Chinese had hempen-bound bamboo scrolls to write on, yet by the 2nd century AD had invented the process which created a writing medium that was both cheap and easy to produce. The invention of the aided in the hauling of heavy loads. The maritime junk ship and stern-mounted steering rudder enabled the Chinese to venture out of waters of interior lakes and rivers. The invention of the reference for maps and raised-relief map allowed the Chinese to better navigate their terrain. In medicine, they used new herbal remedies to cure illnesses, calisthenics to keep physically fit, authorities in the capital were warned ahead of time of the direction of sudden earthquakes with the invention of the seismometer that was tripped by a vibration-sensitive pendulum device. To mark the passing of the seasons and special occasions, the Han Chinese used two variations of the calendar, which were established due to efforts in astronomy and mathematics. Hundreds of new roads and canals were built to transport, commerce, tax collection, communication. The Han-era Chinese also employed several types of bridges to cross waterways and deep gorges, such as bridges, arch bridges, simple suspension bridges. Han ruins of defensive city walls made of brick or rammed earth still stand today, if Mohism, rich in scientific thought, had rapidly grown and strengthened, the situation might have been very favorable to the development of a scientific structure. However, this did not happen because the seeds of the structure of science were never formed. During the late Eastern Han, disastrous upheavals again occurred in the process of social transformation, one can imagine the effect of this calamity on science. The most common writing mediums found in archaeological digs from ancient sites predating the Han period are shells, the written characters on these narrow flat strips of bamboo were arranged into vertical columns. Yet Chinese hempen paper of the Western Han and early Eastern Han eras was of a coarse quality, by the 3rd century, paper became one of Chinas chief writing mediums. The Han ceramics industry was upheld by private businesses as well as government agencies. Ceramics were used in domestic wares and utensils as well as materials for roof tiles. Kilns of the Han dynasty making grey pottery were able to reach firing temperatures above 1,000 °C, however, hard southern Chinese pottery made from a dense adhesive clay native only in the south was fired at even higher temperatures than grey pottery during the Han

Han dynasty
–
The Han dynasty was the second imperial dynasty of China, preceded by the Qin dynasty and succeeded by the Three Kingdoms period. Spanning over four centuries, the Han period is considered an age in Chinese history. To this day, Chinas majority ethnic group refers to itself as the Han people and it was founded by the rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han, and briefly interrupted by the Xin dynasty of the former regent Wang Mang. This interregnum separates the Han dynasty into two periods, the Western Han or Former Han and the Eastern Han or Later Han, the emperor was at the pinnacle of Han society. He presided over the Han government but shared power with both the nobility and appointed ministers who came largely from the gentry class. The Han Empire was divided into areas controlled by the central government using an innovation inherited from the Qin known as commanderies. These kingdoms gradually lost all vestiges of their independence, particularly following the Rebellion of the Seven States, from the reign of Emperor Wu onward, the Chinese court officially sponsored Confucianism in education and court politics, synthesized with the cosmology of later scholars such as Dong Zhongshu. This policy endured until the fall of the Qing dynasty in 1911 AD, the Han dynasty was an age of economic prosperity and saw a significant growth of the money economy first established during the Zhou dynasty. The coinage issued by the government mint in 119 BC remained the standard coinage of China until the Tang dynasty. The period saw a number of limited institutional innovations, the Xiongnu, a nomadic steppe confederation, defeated the Han in 200 BC and forced the Han to submit as a de facto inferior partner, but continued their raids on the Han borders. Emperor Wu of Han launched several campaigns against them. The ultimate Han victory in these wars eventually forced the Xiongnu to accept vassal status as Han tributaries, the territories north of Hans borders were quickly overrun by the nomadic Xianbei confederation. Imperial authority was seriously challenged by large Daoist religious societies which instigated the Yellow Turban Rebellion. When Cao Pi, King of Wei, usurped the throne from Emperor Xian, following Liu Bangs victory in the Chu–Han Contention, the resulting Han dynasty was named after the Hanzhong fief. Chinas first imperial dynasty was the Qin dynasty, the Qin unified the Chinese Warring States by conquest, but their empire became unstable after the death of the first emperor Qin Shi Huangdi. Within four years, the authority had collapsed in the face of rebellion. Although Xiang Yu proved to be a commander, Liu Bang defeated him at Battle of Gaixia. Liu Bang assumed the title emperor at the urging of his followers and is known posthumously as Emperor Gaozu, Changan was chosen as the new capital of the reunified empire under Han

Chinese astronomy
–
Astronomy in China has a very long history, with historians indicating that the Chinese were the most persistent and accurate observers of celestial phenomena anywhere in the world before the Arabs. Detailed records of observations began during the Warring States period. The telescope was introduced in the seventeenth century, in 1669, the Peking observatory was completely redesigned and refitted under the direction of Ferdinand Verbiest. Today, China continues to be active in astronomy, with many observatories, one of the main functions was for the purpose of timekeeping. The Chinese used a calendar, but, because the cycles of the sun. The Chinese calendar was considered to be a symbol of a dynasty, as dynasties would rise and fall, astronomers and astrologers of each period would often prepare a new calendar to be made, with observations for that purpose. Astrological divination was also an important part of astronomy, astronomers took careful note of guest stars, which suddenly appeared among the fixed stars. Ancient astronomical records of phenomena like comets and supernovae are used in modern astronomical studies. The Chinese developed three different cosmological models, the Gai Tian, or hemispherical dome, model conceived the heavens as a hemisphere lying over a dome-shaped earth. The second cosmological model, associated with the Hun Tian school, saw the heavens as a celestial sphere not unlike the spherical models developed in the Greek, the divisions of the sky began with the Northern Dipper and the 28 mansions. In 1977, a box was excavated from the tomb of Yi. Names of the 28 lunar mansions were found on the cover of the box, as lunar mansions have such an ancient origin, the meanings of most of their names have become obscure. Even worse, the name of each lunar mansion consists of only one Chinese word, the meanings of the names are still under discussion. Besides the 28 lunar mansions, most constellations are based on the works of Shi Shen-fu and Gan De, in the fourth century BC, the two Chinese astronomers responsible for the earliest information going into the star catalogues were Shi Shen and Gan De of the Warring States period. These books appeared to have lasted until the sixth century, but were lost after that, a number of books share similar names, often quoted and named after them. These texts should not be confused with the original written by them. Notable works that helped preserve the contents include, Wu Xian has been one of the astronomers in debate and he is often represented as one of the Three Schools Astronomical tradition along with Gan and Shi. Moreover, it was customary in the past for the Chinese to forge works of notable scholars, Wu Xian is generally mentioned as the astronomer who lived many years before Gan and Shi

Titus
–
Titus was Roman emperor from 79 to 81. A member of the Flavian dynasty, Titus succeeded his father Vespasian upon his death, prior to becoming Emperor, Titus gained renown as a military commander, serving under his father in Judea during the First Jewish–Roman War. The campaign came to a halt with the death of emperor Nero in 68. When Vespasian was declared Emperor on 1 July 69, Titus was left in charge of ending the Jewish rebellion, in 70, he besieged and captured Jerusalem, and destroyed the city and the Second Temple. For this achievement Titus was awarded a triumph, the Arch of Titus commemorates his victory to this day. Under the rule of his father, Titus gained notoriety in Rome serving as prefect of the Praetorian Guard, despite concerns over his character, Titus ruled to great acclaim following the death of Vespasian in 79, and was considered a good emperor by Suetonius and other contemporary historians. As emperor, he is best known for completing the Colosseum, after barely two years in office, Titus died of a fever on 13 September 81. He was deified by the Roman Senate and succeeded by his younger brother Domitian, Titus was born in Rome, probably on 30 December 39 AD, as the eldest son of Titus Flavius Vespasianus—commonly known as Vespasian—and Domitilla the Elder. He had one sister, Domitilla the Younger, and one younger brother, Titus Flavius Domitianus. One such family was the gens Flavia, which rose from obscurity to prominence in just four generations, acquiring wealth. Tituss great-grandfather, Titus Flavius Petro, had served as a centurion under Pompey during Caesars civil war and his military career ended in disgrace when he fled the battlefield at the Battle of Pharsalus in 48 BC. Nevertheless, Petro managed to improve his status by marrying the extremely wealthy Tertulla, whose fortune guaranteed the upwards mobility of Petros son Titus Flavius Sabinus I, Sabinus himself amassed further wealth and possible equestrian status through his services as tax collector in Asia and banker in Helvetia. By marrying Vespasia Polla he allied himself to the prestigious patrician gens Vespasia, ensuring the elevation of his sons Titus Flavius Sabinus II. The political career of Vespasian included the offices of quaestor, aedile and praetor, and culminated with a consulship in 51, as a military commander, he gained early renown by participating in the Roman invasion of Britain in 43. The story was told that Titus was reclining next to Britannicus, the night he was murdered. Further details on his education are scarce, but it seems he showed promise in the military arts and was a skilled poet. From c.57 to 59 he was a tribune in Germania. He also served in Britannia, perhaps arriving c.60 with reinforcements needed after the revolt of Boudica, in c.63 he returned to Rome and married Arrecina Tertulla, daughter of a former Prefect of the Praetorian Guard

Jerusalem
–
Jerusalem is a city located on a plateau in the Judaean Mountains between the Mediterranean and the Dead Sea. It is considered a city in the three major Abrahamic religions of Judaism, Christianity and Islam. During its long history, Jerusalem has been destroyed at least twice, besieged 23 times, attacked 52 times, the part of Jerusalem called the City of David was settled in the 4th millennium BCE. In 1538, walls were built around Jerusalem under Suleiman the Magnificent, today those walls define the Old City, which has been traditionally divided into four quarters—known since the early 19th century as the Armenian, Christian, Jewish, and Muslim Quarters. The Old City became a World Heritage Site in 1981, and is on the List of World Heritage in Danger, Modern Jerusalem has grown far beyond the Old Citys boundaries. These foundational events, straddling the dawn of the 1st millennium BCE, the sobriquet of holy city was probably attached to Jerusalem in post-exilic times. The holiness of Jerusalem in Christianity, conserved in the Septuagint which Christians adopted as their own authority, was reinforced by the New Testament account of Jesuss crucifixion there, in Sunni Islam, Jerusalem is the third-holiest city, after Mecca and Medina. As a result, despite having an area of only 0, outside the Old City stands the Garden Tomb. Today, the status of Jerusalem remains one of the issues in the Israeli–Palestinian conflict. During the 1948 Arab–Israeli War, West Jerusalem was among the captured and later annexed by Israel while East Jerusalem, including the Old City, was captured. Israel captured East Jerusalem from Jordan during the 1967 Six-Day War and subsequently annexed it into Jerusalem, one of Israels Basic Laws, the 1980 Jerusalem Law, refers to Jerusalem as the countrys undivided capital. All branches of the Israeli government are located in Jerusalem, including the Knesset, the residences of the Prime Minister and President, the international community does not recognize Jerusalem as Israels capital, and the city hosts no foreign embassies. Jerusalem is also home to some non-governmental Israeli institutions of importance, such as the Hebrew University. In 2011, Jerusalem had a population of 801,000, of which Jews comprised 497,000, Muslims 281,000, a city called Rušalim in the Execration texts of the Middle Kingdom of Egypt is widely, but not universally, identified as Jerusalem. Jerusalem is called Urušalim in the Amarna letters of Abdi-Heba, the name Jerusalem is variously etymologized to mean foundation of the god Shalem, the god Shalem was thus the original tutelary deity of the Bronze Age city. The form Yerushalem or Yerushalayim first appears in the Bible, in the Book of Joshua, according to a Midrash, the name is a combination of Yhwh Yireh and the town Shalem. The earliest extra-biblical Hebrew writing of the word Jerusalem is dated to the sixth or seventh century BCE and was discovered in Khirbet Beit Lei near Beit Guvrin in 1961. The inscription states, I am Yahweh thy God, I will accept the cities of Judah and I will redeem Jerusalem, or as other scholars suggest, the mountains of Judah belong to him, to the God of Jerusalem

Nobility
–
The privileges associated with nobility may constitute substantial advantages over or relative to non-nobles, or may be largely honorary, and vary from country to country and era to era. There is often a variety of ranks within the noble class. g, san Marino and the Vatican City in Europe. Hereditary titles often distinguish nobles from non-nobles, although in many nations most of the nobility have been un-titled, some countries have had non-hereditary nobility, such as the Empire of Brazil. The term derives from Latin nobilitas, the noun of the adjective nobilis. In modern usage, nobility is applied to the highest social class in pre-modern societies and it rapidly came to be seen as a hereditary caste, sometimes associated with a right to bear a hereditary title and, for example in pre-revolutionary France, enjoying fiscal and other privileges. Nobility is a historical, social and often legal notion, differing from high socio-economic status in that the latter is based on income. Being wealthy or influential cannot, ipso facto, make one noble, various republics, including former Iron Curtain countries, Greece, Mexico, and Austria have expressly abolished the conferral and use of titles of nobility for their citizens. Not all of the benefits of nobility derived from noble status per se, usually privileges were granted or recognised by the monarch in association with possession of a specific title, office or estate. Most nobles wealth derived from one or more estates, large or small and it also included infrastructure such as castle, well and mill to which local peasants were allowed some access, although often at a price. Nobles were expected to live nobly, that is, from the proceeds of these possessions, work involving manual labour or subordination to those of lower rank was either forbidden or frowned upon socially. In some countries, the lord could impose restrictions on such a commoners movements. Nobles exclusively enjoyed the privilege of hunting, in France, nobles were exempt from paying the taille, the major direct tax. In some parts of Europe the right of war long remained the privilege of every noble. During the early Renaissance, duelling established the status of a respectable gentleman, Nobility came to be associated with social rather than legal privilege, expressed in a general expectation of deference from those of lower rank. By the 21st century even that deference had become increasingly minimised, in France, a seigneurie might include one or more manors surrounded by land and villages subject to a nobles prerogatives and disposition. Seigneuries could be bought, sold or mortgaged, if erected by the crown into, e. g. a barony or countship, it became legally entailed for a specific family, which could use it as their title. Yet most French nobles were untitled, in other parts of Europe, sovereign rulers arrogated to themselves the exclusive prerogative to act as fons honorum within their realms. Nobility might be inherited or conferred by a fons honorum

Edward I of England
–
Edward I, also known as Edward Longshanks and the Hammer of the Scots, was King of England from 1272 to 1307. He spent much of his reign reforming royal administration and common law, through an extensive legal inquiry, Edward investigated the tenure of various feudal liberties, while the law was reformed through a series of statutes regulating criminal and property law. Increasingly, however, Edwards attention was drawn towards military affairs, the first son of Henry III, Edward was involved early in the political intrigues of his fathers reign, which included an outright rebellion by the English barons. In 1259, he sided with a baronial reform movement. After reconciliation with his father, however, he remained throughout the subsequent armed conflict. After the Battle of Lewes, Edward was hostage to the rebellious barons, Montfort was defeated at the Battle of Evesham in 1265, and within two years the rebellion was extinguished. With England pacified, Edward joined the Ninth Crusade to the Holy Land, the crusade accomplished little, and Edward was on his way home in 1272 when he was informed that his father had died. Making a slow return, he reached England in 1274 and was crowned at Westminster on 19 August, after suppressing a minor rebellion in Wales in 1276–77, Edward responded to a second rebellion in 1282–83 with a full-scale war of conquest. After a successful campaign, Edward subjected Wales to English rule, built a series of castles and towns in the countryside, next, his efforts were directed towards Scotland. Initially invited to arbitrate a dispute, Edward claimed feudal suzerainty over the kingdom. In the war followed, the Scots persevered, even though the English seemed victorious at several points. At the same there were problems at home. In the mid-1290s, extensive military campaigns required high levels of taxation and these crises were initially averted, but issues remained unsettled. When the King died in 1307, he left to his son, Edward II, Edward I was a tall man for his era, hence the nickname Longshanks. He was temperamental, and this, along with his height, made him an intimidating man, nevertheless, he held the respect of his subjects for the way he embodied the medieval ideal of kingship, as a soldier, an administrator and a man of faith. The Edict remained in effect for the rest of the Middle Ages, Edward was born at the Palace of Westminster on the night of 17–18 June 1239, to King Henry III and Eleanor of Provence. Among his childhood friends was his cousin Henry of Almain, son of King Henrys brother Richard of Cornwall, Henry of Almain would remain a close companion of the prince, both through the civil war that followed, and later during the crusade. Edward was in the care of Hugh Giffard – father of the future Chancellor Godfrey Giffard – until Bartholomew Pecche took over at Giffards death in 1246, there were concerns about Edwards health as a child, and he fell ill in 1246,1247, and 1251

Amerigo Vespucci
–
Colloquially referred to as the New World, this second super continent came to be termed Americas, deriving its name from Americus, the Latin version of Vespuccis first name. Amerigo Vespucci was born and raised in Florence on the Italian Peninsula and he was the third son of Ser Nastagio Vespucci, a Florentine notary, and Lisabetta Mini. The father of Ser Nastagio Vespucci had the name Amerigo Vespucci also, Amerigo Vespucci was educated by his uncle, Fra Giorgio Antonio Vespucci, a Dominican friar of the monastery of San Marco in Florence. Vespucci acquired the favor and protection of Lorenzo di Pierfrancesco de Medici who became the head of the business after the elder Lorenzos death in 1492, just around this time, Vespucci was engaged as the executor of Giannotto Berardi, an Italian merchant who had recently died in Seville. Vespucci organized the fulfillment of Berardis outstanding contract with the Castilian crown to provide twelve vessels for the Indies, after these were delivered, Vespucci continued as a provision contractor for Indies expeditions, and is known to have secured beef supplies for at least one of Columbus voyages. At the invitation of king Manuel I of Portugal, Vespucci participated as observer in several voyages that explored the east coast of South America between 1499 and 1502. On the first of these voyages he was aboard the ship that discovered that South America extended much further south than previously thought, the expeditions became widely known in Europe after two accounts attributed to Vespucci were published between 1502 and 1504. In 1507, Martin Waldseemüller produced a map on which he named the new continent America after the feminine Latin version of Vespuccis first name. In an accompanying book, Waldseemüller published one of the Vespucci accounts, in 1508, the position of chief of navigation of Spain was created for Vespucci, with the responsibility of planning navigation for voyages to the Indies. Two letters attributed to Vespucci were published during his lifetime, mundus Novus was a Latin translation of a lost Italian letter sent from Lisbon to Lorenzo di Pierfrancesco de Medici. It describes a voyage to South America in 1501–1502, mundus Novus was published in late 1502 or early 1503 and soon reprinted and distributed in numerous European countries. Lettera di Amerigo Vespucci delle isole nuovamente trovate in quattro suoi viaggi, printed in 1504 or 1505, it claimed to be an account of four voyages to the Americas made by Vespucci between 1497 and 1504. A Latin translation was published by the German Martin Waldseemüller in 1507 in Cosmographiae Introductio, Vespucci even developed a rudimentary, but fairly accurate method of determining longitude. In the 18th century, three unpublished familiar letters from Vespucci to Lorenzo de Medici were rediscovered, one describes a voyage made in 1499–1500 which corresponds with the second of the four voyages. Another was written from Cape Verde in 1501 in the part of the third of the four voyages. The third letter was sent from Lisbon after the completion of that voyage, some have suggested that Vespucci, in the two letters published in his lifetime, was exaggerating his role and constructed deliberate fabrications. However, many now believe that the two letters were not written by him but were fabrications by others based in part on genuine letters by Vespucci. It was the publication and widespread circulation of the letters that might have led Waldseemüller to name the new continent America on his map of 1507 in Lorraine

Christopher Columbus
–
Christopher Columbus was an Italian explorer, navigator, colonizer, and citizen of the Republic of Genoa. Under the auspices of the Catholic Monarchs of Spain, he completed four voyages across the Atlantic Ocean and those voyages and his efforts to establish permanent settlements on the island of Hispaniola initiated the European colonization of the New World. Western imperialism and economic competition were emerging among European kingdoms through the establishment of routes and colonies. During his first voyage in 1492, he reached the New World instead of arriving at Japan as he had intended, landing on an island in the Bahamas archipelago that he named San Salvador. Over the course of three voyages, he visited the Greater and Lesser Antilles, as well as the Caribbean coast of Venezuela and Central America. These voyages had, therefore, an impact in the historical development of the modern Western world. He spearheaded the transatlantic trade and has been accused by several historians of initiating the genocide of the Hispaniola natives. Columbus himself saw his accomplishments primarily in the light of spreading the Christian religion, Columbus never admitted that he had reached a continent previously unknown to Europeans, rather than the East Indies for which he had set course. He called the inhabitants of the lands that he visited indios, the name Christopher Columbus is the Anglicisation of the Latin Christophorus Columbus. His name in Italian is Cristoforo Colombo and, in Spanish and he was born before 31 October 1451 in the territory of the Republic of Genoa, though the exact location remains disputed. His father was Domenico Colombo, a wool weaver who worked both in Genoa and Savona and who also owned a cheese stand at which young Christopher worked as a helper. Bartolomeo, Giovanni Pellegrino, and Giacomo were his brothers, Bartolomeo worked in a cartography workshop in Lisbon for at least part of his adulthood. He also had a sister named Bianchinetta, Columbus never wrote in his native language, which is presumed to have been a Genoese variety of Ligurian. In one of his writings, he says he went to sea at the age of 10, in 1470, the Columbus family moved to Savona, where Domenico took over a tavern. In the same year, Christopher was on a Genoese ship hired in the service of René of Anjou to support his attempt to conquer the Kingdom of Naples. Some modern historians have argued that he was not from Genoa but, instead and these competing hypotheses have generally been discounted by mainstream scholars. In 1473, Columbus began his apprenticeship as business agent for the important Centurione, Di Negro, later, he allegedly made a trip to Chios, an Aegean island then ruled by Genoa. In May 1476, he took part in a convoy sent by Genoa to carry valuable cargo to northern Europe

Cayman Islands
–
The Cayman Islands is a British Overseas Territory in the western Caribbean Sea. Its population is approximately 60,000, and its capital is George Town, the Cayman Islands are considered to be part of the geographic Western Caribbean Zone as well as the Greater Antilles. The territory is considered a major world offshore financial haven for many wealthy individuals. The Cayman Islands remained largely uninhabited until the 17th century, the first recorded permanent inhabitant of the Cayman Islands, Isaac Bodden, was born on Grand Cayman around 1661. He was the grandson of the original settler named Bodden who was one of Oliver Cromwells soldiers at the taking of Jamaica in 1655. England took formal control of the Cayman Islands, along with Jamaica, following several unsuccessful attempts at settlement, a permanent English-speaking population in the islands dates from the 1730s. With settlement, after the first royal land grant by the Governor of Jamaica in 1734, many were brought to the islands from Africa, this is evident today with the majority of native Caymanians being of African and English descent. The results of the first census taken in the islands in 1802 showed the population on Grand Cayman to be 933 with 545 of those inhabitants being enslaved, slavery was abolished in the Cayman Islands in 1833. At the time of abolition, there were over 950 Blacks of African ancestry enslaved by 116 white families of English ancestry. The islands continued to be governed as part of the Colony of Jamaica until 1962, the Cayman Islands historically have been a tax-exempt destination. On 8 February 1794, the Caymanians rescued the crews of a group of ten merchant ships, including HMS Convert, the ships had struck a reef and run aground during rough seas. Legend has it that King George III rewarded the island with a never to introduce taxes as compensation for their generosity. While this remains a legend, the story is not true. However, whatever the history, in practice the government of the Cayman Islands has always relied on indirect, the islands have never levied income tax, capital gains tax, or any wealth tax, making them a popular tax haven. On 11 September 2004 the island of Grand Cayman, which lies largely unprotected at sea level, was hit by Hurricane Ivan, an estimated 83% of the dwellings on the island were damaged including 4% requiring complete reconstruction. A reported 70% of all dwellings suffered severe damage from flooding or wind, another 26% sustained minor damage from partial roof removal, low levels of flooding, or impact with floating or wind driven hurricane debris. Power, water and communications were disrupted for months in areas as Ivan was the worst hurricane to hit the islands in 86 years. Grand Cayman began a rebuilding process and within two years its infrastructure was nearly returned to pre-hurricane status.23 years
