The Irish are a Celtic nation and ethnic group native to the island of Ireland, who share a common Irish ancestry and culture. Ireland has been inhabited for about 12,500 years according to archaeological studies. For most of Ireland's recorded history, the Irish have been a Gaelic people. Viking invasions of Ireland during the 8th to 11th centuries established the cities of Dublin, Waterford and Limerick. Anglo-Normans conquered parts of Ireland in the 12th century, while England's 16th/17th-century conquest and colonisation of Ireland brought a large number of English and Lowland Scots people to parts of the island the north. Today, Ireland is made up of the Republic of the smaller Northern Ireland; the people of Northern Ireland hold various national identities including British, Northern Irish or some combination thereof. The Irish have their own customs, music, sports and mythology. Although Irish was their main language in the past, today most Irish people speak English as their first language.
The Irish nation was made up of kin groups or clans, the Irish had their own religion, law code and style of dress. There have been many notable Irish people throughout history. After Ireland's conversion to Christianity, Irish missionaries and scholars exerted great influence on Western Europe, the Irish came to be seen as a nation of "saints and scholars"; the 6th-century Irish monk and missionary Columbanus is regarded as one of the "fathers of Europe", followed by saints Cillian and Fergal. The scientist Robert Boyle is considered the "father of chemistry", Robert Mallet one of the "fathers of seismology". Famous Irish writers include Oscar Wilde, W. B. Yeats, Samuel Beckett, George Bernard Shaw, Bram Stoker, James Joyce, C. S. Lewis and Seamus Heaney. Notable Irish explorers include Brendan the Navigator, Sir Robert McClure, Sir Alexander Armstrong, Sir Ernest Shackleton and Tom Crean. By some accounts, the first European child born in North America had Irish descent on both sides. Many presidents of the United States have had some Irish ancestry.
The population of Ireland is about 6.3 million, but it is estimated that 50 to 80 million people around the world have Irish forebears, making the Irish diaspora one of the largest of any nation. Emigration from Ireland has been the result of conflict and economic issues. People of Irish descent are found in English-speaking countries Great Britain, the United States and Australia. There are significant numbers in Argentina and New Zealand; the United States has the most people of Irish descent, while in Australia those of Irish descent are a higher percentage of the population than in any other country outside Ireland. Many Icelanders have Scottish Gaelic forebears. During the past 12,500 years of inhabitation, Ireland has witnessed some different peoples arrive on its shores; the ancient peoples of Ireland—such as the creators of the Céide Fields and Newgrange—are unknown. Neither their languages nor the terms they used to describe; as late as the middle centuries of the 1st millennium the inhabitants of Ireland did not appear to have a collective name for themselves.
Ireland itself was known by a number of different names, including Banba, Fódla, Ériu by the islanders and Hiverne to the Greeks, Hibernia to the Romans. Scotland takes its name from Scota, who in Irish mythology, Scottish mythology, pseudohistory, is the name given to two different mythological daughters of two different Egyptian Pharaohs to whom the Gaels traced their ancestry explaining the name Scoti, applied by the Romans to Irish raiders, to the Irish invaders of Argyll and Caledonia which became known as Scotland. Other Latin names for people from Ireland in Classic and Mediaeval sources include Attacotti and Gael; this last word, derived from the Welsh gwyddel "raiders", was adopted by the Irish for themselves. However, as a term it is on a par with Viking, as it describes an activity and its proponents, not their actual ethnic affiliations; the terms Irish and Ireland are derived from the goddess Ériu. A variety of historical ethnic groups have inhabited the island, including the Airgialla, Fir Ol nEchmacht, Fir Bolg, Érainn, Eóganachta, Conmaicne and Ulaid.
In the cases of the Conmaicne, Érainn, it can be demonstrated that the tribe took their name from their chief deity, or in the case of the Ciannachta, Eóganachta, the Soghain, a deified ancestor. This practice is paralleled by the Anglo-Saxon dynasties' claims of descent from Woden, via his sons Wecta, Baeldaeg and Wihtlaeg; the Greek mythographer Euhemerus originated the concept of Euhemerism, which treats mythological accounts as a reflection of actual historical events shaped by retelling and traditional mores. In the 12th century, Icelandic bard and historian Snorri Sturluson proposed that the Norse gods were historical war leaders and kings, who became cult figures set into society as gods; this view is in agreement with Irish historians such as Francis John Byrne. One legend states that the Irish were descended from one Míl Espáine, whose sons conquered Ireland around 1000 BC or
Population density is a measurement of population per unit area or unit volume. It is applied to living organisms, most of the time to humans, it is a key geographical term. In simple terms population density refers to the number of people living in an area per kilometer square. Population density is population divided by total land water volume, as appropriate. Low densities may lead to further reduced fertility; this is called the Allee effect after the scientist. Examples of the causes in low population densities include: Increased problems with locating sexual mates Increased inbreeding For humans, population density is the number of people per unit of area quoted per square kilometer or square mile; this may be calculated for a county, country, another territory or the entire world. The world's population is around 7,500,000,000 and Earth's total area is 510,000,000 square kilometers. Therefore, the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2. If only the Earth's land area of 150,000,000 km2 is taken into account human population density is 50 per km2.
This includes all continental and island land area, including Antarctica. If Antarctica is excluded population density rises to over 55 people per km2. However, over half of the Earth's land mass consists of areas inhospitable to human habitation, such as deserts and high mountains, population tends to cluster around seaports and fresh-water sources. Thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states and dependencies; these territories have a small area and a high urbanization level, with an economically specialized city population drawing on rural resources outside the area, illustrating the difference between high population density and overpopulation The potential to maintain the agricultural aspects of deserts is limited as there is not enough precipitation to support a sustainable land. The population in these areas are low. Therefore, cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace.
Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Most of the most densely populated cities are in Southeast Asia, though Cairo and Lagos in Africa fall into this category. City population and area are, however dependent on the definition of "urban area" used: densities are invariably higher for the central city area than when suburban settlements and the intervening rural areas are included, as in the areas of agglomeration or metropolitan area, the latter sometimes including neighboring cities. For instance, Milwaukee has a greater population density when just the inner city is measured, the surrounding suburbs excluded. In comparison, based on a world population of seven billion, the world's inhabitants, as a loose crowd taking up ten square feet per person, would occupy a space a little larger than Delaware's land area; the Gaza Strip has a population density of 5,046 pop/km.
Although arithmetic density is the most common way of measuring population density, several other methods have been developed to provide a more accurate measure of population density over a specific area. Arithmetic density: The total number of people / area of land Physiological density: The total population / area of arable land Agricultural density: The total rural population / area of arable land Residential density: The number of people living in an urban area / area of residential land Urban density: The number of people inhabiting an urban area / total area of urban land Ecological optimum: The density of population that can be supported by the natural resources Demography Human geography Idealized population Optimum population Population genetics Population health Population momentum Population pyramid Rural transport problem Small population size Distance sampling List of population concern organizations List of countries by population density List of cities by population density List of city districts by population density List of English districts by population density List of European cities proper by population density List of United States cities by population density List of islands by population density List of U.

2016 United States presidential election in Pennsylvania
The 2016 United States presidential election in Pennsylvania took place on November 8, 2016, as part of the 2016 general election in which all fifty states and the District of Columbia participated. Pennsylvania voters chose electors to represent them in the Electoral College via a popular vote. On April 26, 2016, in the presidential primaries, voters selected the Democratic and Green parties' respective nominees for president. Pennsylvania is a closed primary state, meaning voters must have been registered with a particular political party in order to vote for one of that parties' candidates, to participate in their respective party primary; the Republican party candidate, former host of The Apprentice, an American reality television program, Donald Trump, who won Pennsylvania by 44,292 votes out of more than six million cast, a difference of 0.72% and the narrowest margin in a presidential election for the state in 176 years, since 1840 when William Henry Harrison defeated Martin Van Buren by just 0.12%.
Prior to the election, Pennsylvania was expected to be close as polling showed the results within the margin of error. However, most election experts viewed Pennsylvania as solidly Clinton. On Election Day, Pennsylvania swung to Donald Trump. Trump carried 56 of the state's 67 counties, predominantly rural or semi-rural counties, while Clinton carried much of the Philadelphia metropolitan area as well as other cities including Pittsburgh and Scranton. Nonetheless, some areas of traditional Democratic strength such as Luzerne County, where Wilkes-Barre is located, saw swings in margins of up to 25% toward Donald Trump, making him the first Republican candidate for president to carry Pennsylvania since George H. W. Bush in 1988. 2016 would be the first presidential election in which Pennsylvania voted to the right of the nation since 1976. Pennsylvania held a series of caucuses throughout April, culminating with a meeting on April 30 in Harrisburg, where delegates were assigned. From July 25 to July 28, 2016, Philadelphia hosted the 2016 Democratic National Convention.
It was held at the Wells Fargo Center with ancillary meetings at the Pennsylvania Convention Center. Former Secretary of State Hillary Clinton was elected as the party's nominee for president by a 59.67% majority of delegates present at the convention roll call, defeating primary rival Senator Bernie Sanders, who received 39.16% of votes from delegates, becoming the first female candidate to be formally nominated by a major national party as a presidential candidate in the United States. Her running mate, Senator Tim Kaine, the junior United States Senator from Virginia was chosen by delegates as the party's nominee for vice president by acclamation.

The Italians are a Romance ethnic group and nation native to the Italian peninsula and its neighbouring insular territories. Most Italians share a common culture, ancestry or language. All Italian nationals are citizens of the Italian Republic, regardless of ancestry or nation of residence and may be distinguished from people of Italian descent without Italian citizenship and from ethnic Italians living in territories adjacent to the Italian Peninsula without Italian citizenship; the majority of Italian nationals are speakers of a regional variety thereof. However, many of them speak another regional or minority language native to Italy. In 2017, in addition to about 55 million Italians in Italy, Italian-speaking autonomous groups are found in neighbouring nations: a quarter million are in Switzerland, a large population is in France, the entire population of San Marino, there are smaller groups in Slovenia and Croatia in Istria and Dalmatia; because of the wide-ranging diaspora, about 5 million Italian citizens and nearly 80 million people of full or partial Italian ancestry live outside their own homeland, which include the 62.5% of Argentina's population, 1/3 of Uruguayans, 40% of Paraguayans, 15% of Brazilians, people in other parts of Europe bordering Italy, the Americas and the Middle East.
Italians have influenced and contributed to diverse fields, notably the arts and music and technology, cuisine, jurisprudence and business both abroad and worldwide. Furthermore, Italian people are known for their localism, both regionalist and municipalist; the Latin name Italia according to Strabo's Geographica was used by Greeks to indicate the southwestern tip of the Italian peninsula, corresponding to the current region of Calabria, from the strait of Messina to the line connecting the gulf of Salerno and gulf of Taranto. It most originates with Oscan Víteliú, meaning "land of young cattle"; the bull was a symbol of the southern Italic tribes and was depicted goring the Roman wolf as a defiant symbol of free Italy during the Social War. The name was extended to include all the Italian peninsula south of the Rubicon, still by the end of the 1st century BC, to all of the peninsula and beyond. Latin Italicus as a substantive meaning "a man of Italy" is first recorded in Pliny the Elder, Letters 9.23.
The adjective italianus, from which are derived the Italian name of the Italians is medieval. The Italian peninsula was divided into a multitude of tribal or ethnic territory prior to the Roman conquest of Italy in the 3rd century BC. After a series of wars between Greeks and Etruscans, the Latins, with Rome as their capital, gained the ascendancy by 272 BC, completed the conquest of the Italian peninsula by 218 BC; this period of unification was followed by one of conquest in the Mediterranean, beginning with the First Punic War against Carthage. In the course of the century-long struggle against Carthage, the Romans conquered Sicily and Corsica. In 146 BC, at the conclusion of the Third Punic War, with Carthage destroyed and its inhabitants enslaved, Rome became the dominant power in the Mediterranean; the process of Italian unification, the associated Romanization, culminated in 88 BC, when, in the aftermath of the Social War, Rome granted its Italian allies full rights in Roman society, extending Roman citizenship to all Italic peoples.
From its inception, Rome was a republican city-state, but four famous civil conflicts destroyed the republic: Lucius Cornelius Sulla against Gaius Marius and his son, Julius Caesar against Pompey, Marcus Junius Brutus and Gaius Cassius Longinus against Mark Antony and Octavian, Mark Antony against Octavian. Octavian, the final victor, was accorded the title of Augustus by the Senate and thereby became the first Roman emperor. Augustus created for the first time an administrative region called Italia with inhabitants called "Italicus populus", stretching from the Alps to Sicily: for this reason historians like Emilio Gentile called him Father of Italians. In the 1st century BC, Italia was still a collection of territories with different political statuses; some cities, called municipia, had some independence from Rome, while others, the coloniae, were founded by the Romans themselves. Around 7 BC, Augustus divided Italy into eleven regiones. During the Crisis of the Third Century the Roman Empire nearly collapsed under the combined pressures of invasions, military anarchy and civil wars, hyperinflation.
In 284, emperor Diocletian restored political stability. The importance of Rome declined; the seats of the Caesars were Augusta Treverorum for Constantius Chlorus and Sirmium (on the Riv
Democratic Party (United States)
The Democratic Party is one of the two major contemporary political parties in the United States, along with the Republican Party. Tracing its heritage back to Thomas Jefferson and James Madison's Democratic-Republican Party, the modern-day Democratic Party was founded around 1828 by supporters of Andrew Jackson, making it the world's oldest active political party; the Democrats' dominant worldview was once social conservatism and economic liberalism, while populism was its leading characteristic in the rural South. In 1912, Theodore Roosevelt ran as a third-party candidate in the Progressive Party, beginning a switch of political platforms between the Democratic and Republican Party over the coming decades, leading to Woodrow Wilson being elected as the first fiscally progressive Democrat. Since Franklin D. Roosevelt and his New Deal coalition in the 1930s, the Democratic Party has promoted a social liberal platform, supporting social justice. Well into the 20th century, the party had conservative pro-business and Southern conservative-populist anti-business wings.
The New Deal Coalition of 1932–1964 attracted strong support from voters of recent European extraction—many of whom were Catholics based in the cities. After Franklin D. Roosevelt's New Deal of the 1930s, the pro-business wing withered outside the South. After the racial turmoil of the 1960s, most Southern whites and many Northern Catholics moved into the Republican Party at the presidential level; the once-powerful labor union element became less supportive after the 1970s. White Evangelicals and Southerners became Republican at the state and local level since the 1990s. People living in metropolitan areas, women and gender minorities, college graduates, racial and ethnic minorities in the United States, such as Jewish Americans, Hispanic Americans, Asian Americans, Arab Americans and African Americans, tend to support the Democratic Party much more than they support the rival Republican Party; the Democratic Party's philosophy of modern liberalism advocates social and economic equality, along with the welfare state.
It seeks to provide government regulation in the economy. These interventions, such as the introduction of social programs, support for labor unions, affordable college tuitions, moves toward universal health care and equal opportunity, consumer protection and environmental protection form the core of the party's economic policy. Fifteen Democrats have served as President of the United States; the first was President Andrew Jackson, the seventh president and served from 1829 to 1837. The most recent was President Barack Obama, the 44th president and held office from 2009 to 2017. Following the 2018 midterm elections, the Democrats held a majority in the House of Representatives, "trifectas" in 14 states, the mayoralty of numerous major American cities, such as Boston, Los Angeles, New York City, San Francisco, Portland and Washington, D. C. Twenty-three state governors were Democrats, the Party was the minority party in the Senate and in most state legislatures; as of March 2019, four of the nine Justices of the Supreme Court had been appointed by Democratic presidents.
Democratic Party officials trace its origins to the inspiration of the Democratic-Republican Party, founded by Thomas Jefferson, James Madison and other influential opponents of the Federalists in 1792. That party inspired the Whigs and modern Republicans. Organizationally, the modern Democratic Party arose in the 1830s with the election of Andrew Jackson. Since the nomination of William Jennings Bryan in 1896, the party has positioned itself to the left of the Republican Party on economic issues, they have been more liberal on civil rights issues since 1948. On foreign policy, both parties have changed position several times; the Democratic Party evolved from the Jeffersonian Republican or Democratic-Republican Party organized by Jefferson and Madison in opposition to the Federalist Party of Alexander Hamilton and John Adams. The party favored republicanism; the Democratic-Republican Party came to power in the election of 1800. After the War of 1812, the Federalists disappeared and the only national political party left was the Democratic-Republicans.
The era of one-party rule in the United States, known as the Era of Good Feelings, lasted from 1816 until the early 1830s, when the Whig Party became a national political group to rival the Democratic-Republicans. However, the Democratic-Republican Party still had its own internal factions, they split over the choice of a successor to President James Monroe and the party faction that supported many of the old Jeffersonian principles, led by Andrew Jackson and Martin Van Buren, became the modern Democratic Party. As Norton explains the transformation in 1828: Jacksonians believed the people's will had prevailed. Through a lavishly financed coalition of state parties, political leaders, newspaper editors, a popular movement had elected the president; the Democrats became the nation's first well-organized national party and tight party organization became the hallmark of nineteenth-century American politics. Opposing factions led by Henry Clay helped form the Whig Party; the Democratic Party had a small yet decisive advantage over the Whigs until the 1850s, when the Whigs fell apart over the issue of slavery.
In 1854, angry with the Kansas–Nebraska Act, anti-slavery Dem
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
Germans are a Germanic ethnic group native to Central Europe, who share a common German ancestry and history. German is the shared mother tongue of a substantial majority of ethnic Germans; the English term Germans has referred to the German-speaking population of the Holy Roman Empire since the Late Middle Ages. Since the outbreak of the Protestant Reformation within the Holy Roman Empire, German society has been characterized by a Catholic-Protestant divide. Of 100 million native speakers of German in the world 80 million consider themselves Germans. There are an additional 80 million people of German ancestry in the United States, Argentina, South Africa, the post-Soviet states, France, each accounting for at least 1 million. Thus, the total number of Germans lies somewhere between 100 and more than 150 million, depending on the criteria applied. Today, people from countries with German-speaking majorities most subscribe to their own national identities and may or may not self-identify as ethnically German.
The German term Deutsche originates from the Old High German word diutisc, referring to the Germanic "language of the people". It is not clear how if at all, the word was used as an ethnonym in Old High German. Used as a noun, ein diutscher in the sense of "a German" emerges in Middle High German, attested from the second half of the 12th century; the Old French term alemans is taken from the name of the Alamanni. It was loaned into Middle English as almains in the early 14th century; the word Dutch is attested in English from the 14th century, denoting continental West Germanic dialects and their speakers. While in most Romance languages the Germans have been named from the Alamanni, the Old Norse and Estonian names for the Germans were taken from that of the Saxons. In Slavic languages, the Germans were given the name of němьci with a meaning "foreigner, one who does not speak "; the English term Germans is only attested from the mid-16th century, based on the classical Latin term Germani used by Julius Caesar and Tacitus.
It replaced Dutch and Almains, the latter becoming obsolete by the early 18th century. The Germans are a Germanic people. Part of the Holy Roman Empire, around 300 independent German states emerged during its decline after the Peace of Westphalia in 1648 ending the Thirty Years War; these states formed into modern Germany in the 19th century. The concept of a German ethnicity is linked to Germanic tribes of antiquity in central Europe; the early Germans originated on the North German Plain as well as southern Scandinavia. By the 2nd century BC, the number of Germans was increasing and they began expanding into eastern Europe and southward into Celtic territory. During antiquity these Germanic tribes remained separate from each other and did not have writing systems at that time. In the European Iron Age the area, now Germany was divided into the La Tène horizon in Southern Germany and the Jastorf culture in Northern Germany. By 55 BC, the Germans had reached the Danube river and had either assimilated or otherwise driven out the Celts who had lived there, had spread west into what is now Belgium and France.
Conflict between the Germanic tribes and the forces of Rome under Julius Caesar forced major Germanic tribes to retreat to the east bank of the Rhine. Roman emperor Augustus in 12 BC ordered the conquest of the Germans, but the catastrophic Roman defeat at the Battle of the Teutoburg Forest resulted in the Roman Empire abandoning its plans to conquer Germania. Germanic peoples in Roman territory were culturally Romanized, although much of Germania remained free of direct Roman rule, Rome influenced the development of German society the adoption of Christianity by the Germans who obtained it from the Romans. In Roman-held territories with Germanic populations, the Germanic and Roman peoples intermarried, Roman and Christian traditions intermingled; the adoption of Christianity would become a major influence in the development of a common German identity. The first major public figure to speak of a German people in general, was the Roman figure Tacitus in his work Germania around 100 AD; however an actual united German identity and ethnicity did not exist and it would take centuries of development of German culture until the concept of a German ethnicity began to become a popular identity.
The Germanic peoples during the Migrations Period came into contact with other peoples. The Limes Germanicus was breached in AD 260. Migrating Germanic tribes commingled with the local Gallo-Roman populations in what is now Swabia and Bavaria; the arrival of the Huns in Europe resulted in Hun conquest of large parts of Eastern Europe, the Huns were allies of the Roman Empire who fought against Germanic tribes, but the Huns cooperated with the Germanic tribe of the Ostrogoths, large numbers of Germans lived within the lands of the Hunnic Empire of
