Illinois is a state in the Midwestern and Great Lakes region of the United States. It has the fifth largest gross domestic product, the sixth largest population, the 25th largest land area of all U. S. states. Illinois is noted as a microcosm of the entire United States. With Chicago in northeastern Illinois, small industrial cities and immense agricultural productivity in the north and center of the state, natural resources such as coal and petroleum in the south, Illinois has a diverse economic base, is a major transportation hub. Chicagoland, Chicago's metropolitan area, encompasses over 65% of the state's population; the Port of Chicago connects the state to international ports via two main routes: from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean and from the Great Lakes to the Mississippi River, via the Illinois Waterway to the Illinois River. The Mississippi River, the Ohio River, the Wabash River form parts of the boundaries of Illinois. For decades, Chicago's O'Hare International Airport has been ranked as one of the world's busiest airports.
Illinois has long had a reputation as a bellwether both in social and cultural terms and, through the 1980s, in politics. The capital of Illinois is Springfield, located in the central part of the state. Although today's Illinois' largest population center is in its northeast, the state's European population grew first in the west as the French settled the vast Mississippi of the Illinois Country of New France. Following the American Revolutionary War, American settlers began arriving from Kentucky in the 1780s via the Ohio River, the population grew from south to north. In 1818, Illinois achieved statehood. Following increased commercial activity in the Great Lakes after the construction of the Erie Canal, Chicago was founded in the 1830s on the banks of the Chicago River at one of the few natural harbors on the southern section of Lake Michigan. John Deere's invention of the self-scouring steel plow turned Illinois's rich prairie into some of the world's most productive and valuable farmland, attracting immigrant farmers from Germany and Sweden.
The Illinois and Michigan Canal made transportation between the Great Lakes and the Mississippi River valley faster and cheaper, new railroads carried immigrants to new homes in the country's west and shipped commodity crops to the nation's east. The state became a transportation hub for the nation. By 1900, the growth of industrial jobs in the northern cities and coal mining in the central and southern areas attracted immigrants from Eastern and Southern Europe. Illinois was an important manufacturing center during both world wars; the Great Migration from the South established a large community of African Americans in the state, including Chicago, who founded the city's famous jazz and blues cultures. Chicago, the center of the Chicago Metropolitan Area, is now recognized as a global alpha-level city. Three U. S. presidents have been elected while living in Illinois: Abraham Lincoln, Ulysses S. Grant, Barack Obama. Additionally, Ronald Reagan, whose political career was based in California, was born and raised in the state.
Today, Illinois honors Lincoln with its official state slogan Land of Lincoln, displayed on its license plates since 1954. The state is the site of the Abraham Lincoln Presidential Library and Museum in Springfield and the future home of the Barack Obama Presidential Center in Chicago. "Illinois" is the modern spelling for the early French Catholic missionaries and explorers' name for the Illinois Native Americans, a name, spelled in many different ways in the early records. American scholars thought the name "Illinois" meant "man" or "men" in the Miami-Illinois language, with the original iliniwek transformed via French into Illinois; this etymology is not supported by the Illinois language, as the word for "man" is ireniwa, plural of "man" is ireniwaki. The name Illiniwek has been said to mean "tribe of superior men", a false etymology; the name "Illinois" derives from the Miami-Illinois verb irenwe·wa - "he speaks the regular way". This was taken into the Ojibwe language in the Ottawa dialect, modified into ilinwe·.
The French borrowed these forms, changing the /we/ ending to spell it as -ois, a transliteration for its pronunciation in French of that time. The current spelling form, began to appear in the early 1670s, when French colonists had settled in the western area; the Illinois's name for themselves, as attested in all three of the French missionary-period dictionaries of Illinois, was Inoka, of unknown meaning and unrelated to the other terms. American Indians of successive cultures lived along the waterways of the Illinois area for thousands of years before the arrival of Europeans; the Koster Site demonstrates 7,000 years of continuous habitation. Cahokia, the largest regional chiefdom and urban center of the Pre-Columbian Mississippian culture, was located near present-day Collinsville, Illinois, they built an urban complex of more than 100 platform and burial mounds, a 50-acre plaza larger than 35 football fields, a woodhenge of sacred cedar, all in a planned design expressing the culture's cosmology.
Monks Mound, the center of the site, is the largest Pre-Columbian structure north of the Valley of Mexico. It is 100 feet high, 951 feet long, 836 feet wide, covers 13.8 acres. It contains about 814,000 cubic yards of earth, it was topped by a structure thought to have measured about 105 feet in length and 48 feet in width, covered an area 5,000 square feet, been as much as 50 feet high, making its peak 150 feet above the level of the pl

Race and ethnicity in the United States Census
Race and ethnicity in the United States Census, defined by the federal Office of Management and Budget and the United States Census Bureau, are self-identification data items in which residents choose the race or races with which they most identify, indicate whether or not they are of Hispanic or Latino origin. The racial categories represent a social-political construct for the race or races that respondents consider themselves to be and, "generally reflect a social definition of race recognized in this country." OMB defines the concept of race as outlined for the US Census as not "scientific or anthropological" and takes into account "social and cultural characteristics as well as ancestry", using "appropriate scientific methodologies" that are not "primarily biological or genetic in reference." The race categories include both national-origin groups. Race and ethnicity are considered separate and distinct identities, with Hispanic or Latino origin asked as a separate question. Thus, in addition to their race or races, all respondents are categorized by membership in one of two ethnic categories, which are "Hispanic or Latino" and "Not Hispanic or Latino".
However, the practice of separating "race" and "ethnicity" as different categories has been criticized both by the American Anthropological Association and members of US Commission on Civil Rights. In 1997, OMB issued a Federal Register notice regarding revisions to the standards for the classification of federal data on race and ethnicity. OMB developed race and ethnic standards in order to provide "consistent data on race and ethnicity throughout the Federal Government; the development of the data standards stem in large measure from new responsibilities to enforce civil rights laws." Among the changes, OMB issued the instruction to "mark one or more races" after noting evidence of increasing numbers of interracial children and wanting to capture the diversity in a measurable way and having received requests by people who wanted to be able to acknowledge their or their children's full ancestry rather than identifying with only one group. Prior to this decision, the Census and other government data collections asked people to report only one race.
The OMB states, "many federal programs are put into effect based on the race data obtained from the decennial census. Race data are critical for the basic research behind many policy decisions. States require these data to meet legislative redistricting requirements; the data are needed to monitor compliance with the Voting Rights Act by local jurisdictions". "Data on ethnic groups are important for putting into effect a number of federal statutes. Data on Ethnic Groups are needed by local governments to run programs and meet legislative requirements." The 1790 United States Census was the first census in the history of the United States. The population of the United States was recorded as 3,929,214 as of Census Day, August 2, 1790, as mandated by Article I, Section 2 of the United States Constitution and applicable laws."The law required that every household be visited, that completed census schedules be posted in'two of the most public places within, there to remain for the inspection of all concerned...' and that'the aggregate amount of each description of persons' for every district be transmitted to the president."
This law along with U. S. marshals were responsible for governing the census. One third of the original census data has been lost or destroyed since documentation; the data was lost in 1790–1830 time period and included data from: Connecticut, Maryland, New Hampshire, New York, North Carolina, Rhode Island, South Carolina, Delaware, New Jersey, Virginia. Census data included the name of the head of the family and categorized inhabitants as follows: free white males at least 16 years of age, free white males under 16 years of age, free white females, all other free persons, slaves. Thomas Jefferson the Secretary of State, directed marshals to collect data from all thirteen states, from the Southwest Territory; the census was not conducted in Vermont until 1791, after that state's admission to the Union as the 14th state on March 4 of that year. There was some doubt surrounding the numbers, President George Washington and Thomas Jefferson maintained the population was undercounted; the potential reasons Washington and Jefferson may have thought this could be refusal to participate, poor public transportation and roads, spread out population, restraints of current technology.
No microdata from the 1790 population census is available, but aggregate data for small areas and their compatible cartographic boundary files, can be downloaded from the National Historical Geographic Information System. In 1800 and 1810, the age question regarding free white males was more detailed; the 1820
West Virginia is a state located in the Appalachian region in the Southern United States, considered to be a part of the Middle Atlantic States. It is bordered by Pennsylvania to the north, Maryland to the east and northeast, Virginia to the southeast, Kentucky to the southwest, Ohio to the northwest. West Virginia is the 41st largest state by area, is ranked 38th in population; the capital and largest city is Charleston. West Virginia became a state following the Wheeling Conventions of 1861, after the American Civil War had begun. Delegates from some Unionist counties of northwestern Virginia decided to break away from Virginia, although they included many secessionist counties in the new state. West Virginia was admitted to the Union on June 20, 1863, was a key border state during the war. West Virginia was the only state to form by separating from a Confederate state, the first to separate from any state since Maine separated from Massachusetts, was one of two states admitted to the Union during the American Civil War.
While a portion of its residents held slaves, most of the residents were yeomen farmers, the delegates provided for gradual abolition of slavery in the new state Constitution. The Census Bureau and the Association of American Geographers classify West Virginia as part of the Southern United States; however the Bureau of Labor Statistics classifies West Virginia as a part of the Mid-Atlantic. The northern panhandle extends adjacent to Pennsylvania and Ohio, with the West Virginia cities of Wheeling and Weirton just across the border from the Pittsburgh metropolitan area, while Bluefield is less than 70 miles from North Carolina. Huntington in the southwest is close to the states of Ohio and Kentucky, while Martinsburg and Harpers Ferry in the Eastern Panhandle region are considered part of the Washington metropolitan area, in between the states of Maryland and Virginia; the unique position of West Virginia means that it is included in several geographical regions, including the Mid-Atlantic, the Upland South, the Southeastern United States.
It is the only state, within the area served by the Appalachian Regional Commission. The state is noted for its mountains and rolling hills, its significant logging and coal mining industries, its political and labor history, it is known for a wide range of outdoor recreational opportunities, including skiing, whitewater rafting, hiking, mountain biking, rock climbing, hunting. Many ancient man-made earthen mounds from various prehistoric mound builder cultures survive in the areas of present-day Moundsville, South Charleston, Romney; the artifacts uncovered in these give evidence of village societies. They had a tribal trade system culture. In the 1670s during the Beaver Wars, the powerful Iroquois, five allied nations based in present-day New York and Pennsylvania, drove out other American Indian tribes from the region in order to reserve the upper Ohio Valley as a hunting ground. Siouan language tribes, such as the Moneton, had been recorded in the area. A century the area now identified as West Virginia was contested territory among Anglo-Americans as well, with the colonies of Pennsylvania and Virginia claiming territorial rights under their colonial charters to this area before the American Revolutionary War.
Some speculative land companies, such as the Vandalia Company, the Ohio Company and Indiana Company, tried to legitimize their claims to land in parts of West Virginia and present day Kentucky, but failed. This rivalry resulted in some settlers petitioning the Continental Congress to create a new territory called Westsylvania. With the federal settlement of the Pennsylvania and Virginia border dispute, creating Kentucky County, Kentuckians "were satisfied, the inhabitants of a large part of West Virginia were grateful."The Crown considered the area of West Virginia to be part of the British Virginia Colony from 1607 to 1776. The United States considered this area to be the western part of the state of Virginia from 1776 to 1863, before the formation of West Virginia, its residents were discontented for years with their position in Virginia, as the government was dominated by the planter elite of the Tidewater and Piedmont areas. The legislature had electoral malapportionment, based on the counting of slaves toward regional populations, the western white residents were underrepresented in the state legislature.
More subsistence and yeoman farmers lived in the west and they were less supportive of slavery, although many counties were divided on their support. The residents of this area became more divided after the planter elite of eastern Virginia voted to secede from the Union during the Civil War. Residents of the western and northern counties set up a separate government under Francis Pierpont in 1861, which they called the Restored Government. Most voted to separate from Virginia, the new state was admitted to the Union in 1863. In 1864 a state constitutional convention drafted a constitution, ratified by the legislature without putting it to popular vote. West Virginia abolished slavery by a gradual process and temporarily disenfranchised men who had held Confederate office or fought for the Confederacy. West Virginia's history has been profoundly affected by its mountainous terrain and vast river valleys, rich natural resources; these were all factors driving its economy and the lifestyles of its residents, who tended to live in many small isolated communities in the mountain valleys.
A 2010 analysis of
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. In early days, electricity was considered as being not related to magnetism. On, many experimental results and the development of Maxwell's equations indicated that both electricity and magnetism are from a single phenomenon: electromagnetism. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others; the presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges produces a magnetic field; when a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. Thus, if that charge were to move, the electric field would be doing work on the electric charge, thus we can speak of electric potential at a certain point in space, equal to the work done by an external agent in carrying a unit of positive charge from an arbitrarily chosen reference point to that point without any acceleration and is measured in volts.
Electricity is at the heart of many modern technologies, being used for: electric power where electric current is used to energise equipment. Electrical phenomena have been studied since antiquity, though progress in theoretical understanding remained slow until the seventeenth and eighteenth centuries. Practical applications for electricity were few, it would not be until the late nineteenth century that electrical engineers were able to put it to industrial and residential use; the rapid expansion in electrical technology at this time transformed industry and society, becoming a driving force for the Second Industrial Revolution. Electricity's extraordinary versatility means it can be put to an limitless set of applications which include transport, lighting and computation. Electrical power is now the backbone of modern industrial society. Long before any knowledge of electricity existed, people were aware of shocks from electric fish. Ancient Egyptian texts dating from 2750 BCE referred to these fish as the "Thunderer of the Nile", described them as the "protectors" of all other fish.
Electric fish were again reported millennia by ancient Greek and Arabic naturalists and physicians. Several ancient writers, such as Pliny the Elder and Scribonius Largus, attested to the numbing effect of electric shocks delivered by catfish and electric rays, knew that such shocks could travel along conducting objects. Patients suffering from ailments such as gout or headache were directed to touch electric fish in the hope that the powerful jolt might cure them; the earliest and nearest approach to the discovery of the identity of lightning, electricity from any other source, is to be attributed to the Arabs, who before the 15th century had the Arabic word for lightning ra‘ad applied to the electric ray. Ancient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletus made a series of observations on static electricity around 600 BCE, from which he believed that friction rendered amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing.
Thales was incorrect in believing the attraction was due to a magnetic effect, but science would prove a link between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, though it is uncertain whether the artifact was electrical in nature. Electricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber, he coined the New Latin word electricus to refer to the property of attracting small objects after being rubbed. This association gave rise to the English words "electric" and "electricity", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646. Further work was conducted in the 17th and early 18th centuries by Otto von Guericke, Robert Boyle, Stephen Gray and C. F. du Fay.
In the 18th century, Benjamin Franklin conducted extensive research in electricity, selling his possessions to fund his work. In June 1752 he is reputed to have attached a metal key to the bottom of a dampened kite string and flown the kite in a storm-threatened sky. A succession of sparks jumping from the key to the back of his hand showed that lightning was indeed electrical in nature, he explained the paradoxical behavior of the Leyden jar as a device for storing large amounts of electrical charge in terms of electricity consisting of both positive and negative charges. In 1791, Luigi Galvani published his discovery of bioelectromagnetics, demonstrating that electricity was the medium by which neurons passed signals to the muscles. Alessandro Volta's battery, or voltaic pile, of 1800, made from alternating layers of zinc and copper, provided scientists with a more reliable source of electrical energy than the electrostatic machines used; the recognition of electromagnetism, the unity of electric
United Mine Workers
The United Mine Workers of America is a North American labor union best known for representing coal miners. Today, the Union represents health care workers, truck drivers, manufacturing workers and public employees in the United States and Canada. Although its main focus has always been on workers and their rights, the UMW of today advocates for better roads and universal health care. By 2014, coal mining had shifted to open pit mines in Wyoming, there were only 60,000 active coal miners; the UMW was left with 35,000 members, of whom 20,000 were coal miners, chiefly in underground mines in Kentucky and West Virginia. However it was responsible for pensions and medical benefits for 40,000 retired miners, for 50,000 spouses and dependents; the UMW was founded in Columbus, Ohio, on January 25, 1890, with the merger of two old labor groups, the Knights of Labor Trade Assembly No. 135 and the National Progressive Miners Union. Adopting the model of the American Federation of Labor, the union was established as a three-pronged labor tool: to develop mine safety.
After passage of the National Recovery Act in 1933 during the Great Depression, organizers spread throughout the United States to organize all coal miners into labor unions. Under the powerful leadership of John L. Lewis, the UMW broke with the American Federation of Labor and set up its own federation, the CIO, its organizers fanned out to organize major industries, including automobiles, electrical equipment, rubber and chemical, fought a series of battles with the AFL. The UMW grew to 800,000 members and was an element in the New Deal Coalition supporting Democratic President Franklin D. Roosevelt. Lewis broke with Roosevelt in 1940 and left the CIO, leaving the UMW isolated in the labor movement. During World War II the UMW was involved in a series of major strikes and threatened walkouts that angered public opinion and energized pro-business opponents. After the war, the UMW concentrated on gaining large increases in wages, medical services and retirement benefits for its shrinking membership, contending with changes in technology and declining mines in the East.
The UMW was founded in Columbus, Ohio, on January 22, 1890, by the merger of two earlier groups, the Knights of Labor Trade Assembly No. 135 and the National Progressive Miners Union. It was modeled after the American Federation of Labor; the Union's emergence in the 1890s was the culmination of decades of effort to organize mine workers and people in adjacent occupations into a single, effective negotiating unit. At the time coal was one of the most sought natural resources, as it was used to heat homes and to power machines in industries; the coal mines were a dangerous place to work. With the owners imposing reduced wages on a regular basis, in response to fluctuations in pricing, miners sought a group to stand up for their rights. American Miners' Association The first step in starting the union was the creation of the American Miners' Association. Scholars credit this organization with the beginning of the labor movement in the United States; the membership of the group grew rapidly. "Of an estimated 56,000 miners in 1865, John Hinchcliffe claimed 22,000 as members of the AMA.
In response, the mine owners sought to stop the AMA from becoming more powerful. Members of the AMA were blacklisted from employment at other mines. After a short time the AMA began to decline, ceased operations. Workingman's Benevolent Association Another early labor union that arose in 1868 was the Workingmen's Benevolent Association; this union was distinguished as a labor union for workers mining anthracite coal. The laborers formed the WBA to help improve working conditions; the main reason for the success of this group was the president, John Siney, who sought a way both to increase miners benefits while helping the operators earn a profit. They chose to limit the production of anthracite to keep its price profitable; because the efforts of the WBA benefited the operators, they did not object when the union wanted to take action in the mines. Because the operators trusted the WBA, they agreed to the first written contract between miners and operators; as the union became more responsible in the operators' eyes, the union was given more freedoms.
As a result, the health and spirits of the miners improved. The WBA could have been a successful union had it not been for Franklin B. Gowen. In the 1870s Gowen owned the Reading Railroad, bought several coal mines in the area; because he owned the coal mines and controlled the means of transporting the coal, he was able to destroy the labor union. He did everything in his power to produce the cheapest product and to ensure that non-union workers would benefit; as conditions for the miners of the WBA worsened, the union disappeared. After the fall of the WBA, miners created many other small unions, including the Workingman's Protective Association and the Miner's National Association. Although both groups had strong ideas and goals, they were unable to gain enough support and organization to succeed; the two unions did not last long, but provided greater support by the miners for a union which could withstand and help protect the workers' rights. Although many labor unions were failing, two predominant unions arose that held promise to become strong and permanent advocates for the miners.
The main problem during this time was the rivalry between the two groups. Because the
Bohemia is the westernmost and largest historical region of the Czech lands in the present-day Czech Republic. In a broader meaning, Bohemia sometimes refers to the entire Czech territory, including Moravia and Czech Silesia in a historical context, such as the Lands of the Bohemian Crown ruled by Bohemian kings. Bohemia was a duchy of Great Moravia an independent principality, a kingdom in the Holy Roman Empire, subsequently a part of the Habsburg Monarchy and the Austrian Empire. After World War I and the establishment of an independent Czechoslovak state, Bohemia became a part of Czechoslovakia. Between 1938 and 1945, border regions with sizeable German-speaking minorities of all three Czech lands were joined to Nazi Germany as the Sudetenland; the remainder of Czech territory became the Second Czechoslovak Republic and was subsequently occupied as the Protectorate of Bohemia and Moravia, In 1969, the Czech lands were given autonomy within Czechoslovakia as the Czech Socialist Republic. In 1990, the name was changed to the Czech Republic, which became a separate state in 1993 with the split of Czechoslovakia.
Until 1948, Bohemia was an administrative unit of Czechoslovakia as one of its "lands". Since administrative reforms have replaced self-governing lands with a modified system of "regions" which do not follow the borders of the historical Czech lands. However, the three lands are mentioned in the preamble of the Constitution of the Czech Republic: "We, citizens of the Czech Republic in Bohemia and Silesia…"Bohemia had an area of 52,065 km2 and today is home to 6.5 million of the Czech Republic's 10.5 million inhabitants. Bohemia was bordered in the south by Upper and Lower Austria, in the west by Bavaria and in the north by Saxony and Lusatia, in the northeast by Silesia, in the east by Moravia. Bohemia's borders were marked by mountain ranges such as the Bohemian Forest, the Ore Mountains, the Krkonoše, a part of the Sudetes range. In the 2nd century BC, the Romans were competing for dominance in northern Italy with various peoples including the Gauls-Celtic tribe Boii; the Romans defeated the Boii at the Battle of Mutina.
After this, many of the Boii retreated north across the Alps. Much Roman authors refer to the area they had once occupied as Boiohaemum; the earliest mention was by Tacitus' Germania 28, mentions of the same name are in Strabo and Velleius Paterculus. The name appears to include the tribal name Boi- plus the Germanic element *haimaz "home"; this Boiohaemum was isolated to the area where King Marobod's kingdom was centred, within the Hercynian forest. Emperor Constantine VII in 10th century De Administrando Imperio mentioned the region as Boïki; the Czech name "Čechy" is derived from the name of the Slavic ethnic group, the Czechs, who settled in the area during the 6th or 7th century AD. Bohemia, like neighbouring Bavaria, is named after the Boii, who were a large Celtic nation known to the Romans for their migrations and settlement in northern Italy and other places. Another part of the nation moved west with the Helvetii into southern France, one of the events leading to the interventions of Julius Caesar's Gaulish campaign of 58 BC.
The emigration of the Helvetii and Boii left southern Germany and Bohemia a inhabited "desert" into which Suebic peoples arrived, speaking Germanic languages, became dominant over remaining Celtic groups. To the south, over the Danube, the Romans extended their empire, to the southeast in present-day Hungary, were Dacian peoples. In the area of modern Bohemia the Marcomanni and other Suebic groups were led by their king Marobodus, after suffering defeat to Roman forces in Germany, he took advantage of the natural defenses provided by its forests. They were able to maintain a strong alliance with neighbouring tribes including the Lugii, Hermunduri and Buri, sometimes controlled by the Roman Empire, sometimes in conflict with it, for example in the second century when they fought Marcus Aurelius. In late classical times and the early Middle Ages, two new Suebic groupings appeared to the west of Bohemia in southern Germany, the Alemanni, the Bavarians. Many Suebic tribes from the Bohemian region took part in such movements westwards settling as far away as Spain and Portugal.
With them were tribes who had pushed from the east, such as the Vandals, Alans. Other groups pushed southwards towards Pannonia; the last known mention of the kingdom of the Marcomanni, concerning a queen named Fritigil is in the 4th century, she was thought to have lived in or near Pannonia. The Suebian Langobardi, who moved over many generations from the Baltic Sea, via the Elbe and Pannonia to Italy, recorded in a tribal history a time spent in "Bainaib". After this migration period, Bohemia was repopulated around the 6th century, Slavic tribes arrived from the east, their language began to replace the older Germanic and Sarmatian ones; these are precursors of today's Czechs, though the exact amount of Slavic immigration is a subject of debate. The Slavic influx was divided into three waves; the first wave came from the
