Hispanic and Latino Americans
Hispanic Americans and Latino Americans are Americans who are descendants of people from Spain and Latin America, respectively. More it includes all Americans who speak the Spanish language natively, who self-identify as Hispanic or Latino, whether of full or partial ancestry. For the 2010 United States Census, people counted as "Hispanic" or "Latino" were those who identified as one of the specific Hispanic or Latino categories listed on the census questionnaire as well as those who indicated that they were "other Spanish, Hispanic or Latino." The national origins classified as Hispanic or Latino by the United States Census Bureau are the following: Argentine, Colombian, Puerto Rican, Mexican, Costa Rican, Honduran, Panamanian, Bolivian, Spanish American, Ecuadorian, Peruvian and Venezuelan. Brazilian Americans, other Portuguese-speaking Latino groups, non-Spanish speaking Latino groups in the United States are defined as "Latino" by some U. S. government agencies. The Census Bureau uses the terms Hispanic and Latino interchangeably."Origin" can be viewed as the ancestry, nationality group, lineage or country of birth of the person or the person's parents or ancestors before their arrival in the United States.
People who identify as Spanish, Hispanic or Latino may be of any race. As one of the only two designated categories of ethnicity in the United States, Hispanics form a pan-ethnicity incorporating a diversity of inter-related cultural and linguistic heritages. Most Hispanic Americans are of Mexican, Puerto Rican, Salvadoran, Guatemalan or Colombian origin; the predominant origin of regional Hispanic populations varies in different locations across the country. Hispanic Americans are the second fastest-growing ethnic group by percentage growth in the United States after Asian Americans. Hispanic/Latinos overall are the second-largest ethnic group in the United States, after non-Hispanic whites. Hispanics have lived within what is now the United States continuously since the founding of St. Augustine by the Spanish in 1565. After Native Americans, Hispanics are the oldest ethnic group to inhabit much of what is today the United States. Many have Native American ancestry. Spain colonized large areas of what is today the American Southwest and West Coast, as well as Florida.
Its holdings included present-day California, New Mexico, Nevada and Texas, all of which were part of the Republic of Mexico from its independence in 1821 until the end of the Mexican–American War in 1848. Conversely, Hispanic immigrants to the New York-New Jersey metropolitan area derive from a broad spectrum of Latin American states. A study published in 2015 in the American Journal of Human Genetics, based on 23andMe data from 8,663 self-described Latinos, estimated that Latinos in the United States carried a mean of 65.1% European ancestry, 18.0% Native American ancestry, 6.2% African ancestry. The study found that self-described Latinos from the Southwest those along the Mexican border, had the highest mean levels of Native American ancestry; the terms "Hispanic" and "Latino" refer to an ethnicity. Hispanic people may share some commonalities in their language, culture and heritage. According to the Smithsonian Institution, the term "Latino" includes peoples with Portuguese roots, such as Brazilians, as well as those of Spanish-language origin.
In the United States, many Hispanics and Latinos are of both Native American ancestry. Others are predominantly of European ancestry or of Amerindian ancestry. Many Hispanics and Latinos from the Caribbean, as well as other regions of Latin America where African slavery was widespread, may be of sub-Saharan African descent as well; the difference between the terms Hispanic and Latino is confusing to some. The U. S. Census Bureau equates the two terms and defines them as referring to anyone from Spain and the Spanish-speaking countries of the Americas. After the Mexican–American War concluded in 1848, term Hispanic or Spanish American was used to describe the Hispanos of New Mexico within the American Southwest; the 1970 United States Census controversially broadened the definition to "a person of Mexican, Puerto Rican, South or Central American, or other Spanish culture or origin, regardless of race". This is now the common formal and colloquial definition of the term within the United States, outside of New Mexico.
The term Latino has developed a number of definitions. One definition of Latino is "a Latin male in the United States"; this is the oldest and the original definition used in the United States, first used in 1946. This definition encompasses Spanish speakers from both Europe and the Americas. Under this definition, immigrants from Spain and immigrants from Latin America are both Latino; this definition is consistent with the 21st-century usage by the U. S. Census Bureau and OMB, as the two agencies use Latino interchangeably. A definition of Latino is as a condensed form of the term "Latino-Americano", the Spanish word for Latin-American, or someone who comes from Latin America. Under this definition a Mexican American or Puerto Rican, for example, is both a Hispanic and a Latino. A Brazilian American is a Latino by this definition, which includes those of Portuguese-speaking origin from Latin America. However, an immigrant from Spain would be classified as European or White by American sta
Per capita income
Per capita income or average income measures the average income earned per person in a given area in a specified year. It is calculated by dividing the area's total income by its total population. Per capita income is national income divided by population size. Per capita income is used to measure an area's average income and compare the wealth of different populations. Per capita income is used to measure a country's standard of living, it is expressed in terms of a used international currency such as the euro or United States dollar, is useful because it is known, is calculable from available gross domestic product and population estimates, produces a useful statistic for comparison of wealth between sovereign territories. This helps to ascertain a country's development status, it is one of the three measures for calculating the Human Development Index of a country. In the United States, it is defined by the U. S. Census Bureau as the following: "Per capita income is the mean money income received in the past 12 months computed for every man and child in a geographic area."
Critics claim that per capita income has several weaknesses in measuring prosperity: Comparisons of per capita income over time need to consider inflation. Without adjusting for inflation, figures tend to overstate the effects of economic growth. International comparisons can be distorted by cost of living differences not reflected in exchange rates. Where the objective is to compare living standards between countries, adjusting for differences in purchasing power parity will more reflect what people are able to buy with their money, it does not reflect income distribution. If a country's income distribution is skewed, a small wealthy class can increase per capita income while the majority of the population has no change in income. In this respect, median income is more useful when measuring of prosperity than per capita income, as it is less influenced by outliers. Non-monetary activity, such as barter or services provided within the family, is not counted; the importance of these services varies among economies.
Per capita income does not consider whether income is invested in factors to improve the area's development, such as health, education, or infrastructure.

The Detroit Tigers are an American professional baseball team based in Detroit, Michigan. The Tigers compete in Major League Baseball as a member of the American League Central division. One of the AL's eight charter franchises, the club was founded in Detroit as a member of the minor league Western League in 1894 and is the only Western League team still in its original city, they are the oldest continuous one name, one city franchise in the AL. The Tigers have won four World Series championships, 11 AL pennants, four AL Central division championships; the Tigers won division titles in 1972, 1984, 1987 as a member of the AL East. The team plays its home games at Comerica Park in Downtown Detroit; the Tigers constructed Bennett Park at the corner of Michigan Avenue and Trumbull Avenue in Corktown and began playing there in 1896. In 1912, the team moved into Navin Field, built on the same location, it was renamed Briggs Stadium. It was renamed Tiger Stadium in 1961 and the Tigers played there until moving to Comerica Park in 2000.
The franchise was founded as a member of the reorganized Western League in 1894. They played at Boulevard Park, sometimes called League Park, it was located on East Lafayette called Champlain Street, between Helen and East Grand Boulevard, near Belle Isle. In 1895, owner George Vanderbeck decided to build Bennett Park at the corner of Michigan and Trumbull Avenues, which would remain their base of operations for the next 104 seasons; the first game at The Corner was an exhibition on April 13, 1896. The team, now called the "Tigers," beat a local semi-pro team, known as the Athletics, by a score of 30–3, they played their first Western League game at Bennett Park on April 28, 1896, defeating the Columbus Senators 17–2. At the end of the 1897 season, Rube Waddell was lent to the team to gain professional experience. After being fined, Waddell left Detroit to pitch in Canada; when the Western League renamed itself the American League for 1900, it was still a minor league, but the next year, it broke from the National Agreement and declared itself a major league competing with the National League for players and for fans in four contested cities.
For a while, there were rumors of the team relocating to Pittsburgh, but the two leagues made peace in 1903 when they signed a new National Agreement. The Tigers were established as a charter member of the now major league American League in 1901, they played their first game as a major league team at home against the Milwaukee Brewers on April 25, 1901, with an estimated 10,000 fans at Bennett Park. After entering the ninth inning behind 13–4, the team staged a dramatic comeback to win 14–13; the team finished third in the eight-team league. In 1905, the team acquired 18-year-old Ty Cobb, a fearless player with a mean streak, who came to be regarded as one of the greatest players of all time; the addition of Cobb to an talented team that included Sam Crawford, Hughie Jennings, Bill Donovan and George Mullin yielded results. Behind the hitting of outfielders Ty Cobb and Sam Crawford, the pitching of Bill Donovan and Ed Killian, the Tigers went 92–58 to win the AL pennant in 1907 by 1.5 games over the Philadelphia Athletics.
They moved on to their first World Series appearance against the Chicago Cubs. Game 1 ended in a rare 3–3 tie, called due to darkness after 12 innings; the Tigers scored only three runs in the succeeding four games, never scoring more than one run in a game, lost the Series, 4–0. The Tigers won the AL by just a half-game over the 90–64 Cleveland Naps with a 90–63 record. Cobb hit.324, while Sam Crawford hit.311 with 7 home runs, enough to lead the league in the "dead ball" era. The Cubs, would defeat the Tigers again in the 1908 World Series, this time in five games; this would be the Cubs' last World Championship until 2016. In 1909, Detroit posted a 98 -- 54 season. Ty Cobb won the batting triple crown in 1909, hitting.377 with 107 RBIs. He led the league with 76 stolen bases. George Mullin was the pitching hero, going 29–8 with a 2.22 ERA, while fellow pitcher Ed Willett went 21–10. Mullin's 11–0 start in 1909 was a Tiger record for 104 years being broken by Max Scherzer's 13–0 start in 2013, it was hoped that a new opponent in the 1909 Series, the Pittsburgh Pirates, would yield different results.
The Tigers performed better in the Fall Classic, taking Pittsburgh to seven games, but they were blown out 8–0 in the decisive game at Bennett Park. The Tigers dropped to third place in the American League in 1910 with an 86–68 record, they posted 89 wins in 1911 to finish second, but were still well behind a powerhouse Philadelphia Athletics team that won 101 games. The team sunk to a dismal sixth place in both 1913 seasons. A bright spot in 1912 was George Mullin pitching the franchise's first no-hitter in a 7–0 win over the St. Louis Browns on July 4, his 32nd birthday. Cobb went into the stands in a May 15, 1912, game to attack a fan, abusing him, was suspended; the Tigers protested the suspension by fielding a team of replacement players and some coaches, lost 24–2, to the Philadelphia Athletics. During this five-season stretch, Cobb posted batting averages of.383.420.409.390 and.368, winning the AL batting title every year. In 1915, the Tigers won a then-club record 100 games, but narrowly lost the AL pennant to the Boston Red Sox, who won 101 games.
The 1915 Tigers were led by an outfield consisting of Ty Cobb, Sam Crawford, Bobby Vea
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.

2010 United States Census
The 2010 United States Census is the twenty-third and most recent United States national census. National Census Day, the reference day used for the census, was April 1, 2010; the census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired; the population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census. This was the first census in which all states recorded a population of over half a million, as well as the first in which all 100 largest cities recorded populations of over 200,000; as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed. Participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25, 2010, Census Bureau Director Robert Groves inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, a resident of Noorvik, Alaska.
More than 120 million census forms were delivered by the U. S. Post Office beginning March 15, 2010; the number of forms mailed out or hand-delivered by the Census Bureau was 134 million on April 1, 2010. Although the questionnaire used April 1, 2010 as the reference date as to where a person was living, an insert dated March 15, 2010 included the following printed in bold type: "Please complete and mail back the enclosed census form today." The 2010 Census national mail participation rate was 74%. From April through July 2010, census takers visited households that did not return a form, an operation called "non-response follow-up". In December 2010, the U. S. Census Bureau delivered population information to the U. S. President for apportionment, in March 2011, complete redistricting data was delivered to states. Identifiable information will be available in 2082; the Census Bureau did not use a long form for the 2010 Census. In several previous censuses, one in six households received this long form, which asked for detailed social and economic information.
The 2010 Census used only a short form asking ten basic questions: How many people were living or staying in this house, apartment, or mobile home on April 1, 2010? Were there any additional people staying here on April 1, 2010 that you did not include in Question 1? Mark all that apply: Is this house, apartment, or mobile home – What is your telephone number? What is Person 1's name? What is Person 1's sex? What is Person 1's age and Person 1's date of birth? Is Person 1 of Hispanic, Latino, or Spanish origin? What is Person 1's race? Does Person 1 sometimes live or stay somewhere else? The form included space to repeat all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, nor was the form available for download. Detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey; the survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years.
A small percentage of the population on a rotating basis will receive the survey each year, no household will receive it more than once every five years. In June 2009, the U. S. Census Bureau announced. However, the final form did not contain a separate "same-sex married couple" option; when noting the relationship between household members, same-sex couples who are married could mark their spouses as being "Husband or wife", the same response given by opposite-sex married couples. An "unmarried partner" option was available for couples; the 2010 census cost $13 billion $42 per capita. Operational costs were $5.4 billion under the $7 billion budget. In December 2010 the Government Accountability Office noted that the cost of conducting the census has doubled each decade since 1970. In a detailed 2004 report to Congress, the GAO called on the Census Bureau to address cost and design issues, at that time, had estimated the 2010 Census cost to be $11 billion. In August 2010, Commerce Secretary Gary Locke announced that the census operational costs came in under budget.
Locke credited the management practices of Census Bureau director Robert Groves, citing in particular the decision to buy additional advertising in locations where responses lagged, which improved the overall response rate. The agency has begun to rely more on questioning neighbors or other reliable third parties when a person could not be reached at home, which reduced the cost of follow-up visits.

Poznań is a city on the Warta River in west-central Poland, in the Greater Poland region and is the fifth-largest city in Poland. It is best known for its renaissance Old Ostrów Tumski Cathedral. Today, Poznań is an important cultural and business centre and one of Poland's most populous regions with many regional customs such as Saint John's Fair, traditional Saint Martin's croissants and a local dialect. Poznań is among the largest cities in Poland; the city's population is 538,633, while the continuous conurbation with Poznań County and several other communities is inhabited by 1.1 million people. The Larger Poznań Metropolitan Area is inhabited by 1.3–1.4 million people and extends to such satellite towns as Nowy Tomyśl, Gniezno and Września, making it the fourth largest metropolitan area in Poland. It is the historical capital of the Greater Poland region and is the administrative capital of the province called Greater Poland Voivodeship. Poznań is a centre of trade, education and tourism.
It is an important academic site, with about 130,000 students and the Adam Mickiewicz University - the third largest Polish university. Poznań is the seat of the oldest Polish diocese, now being one of the most populous archdioceses in the country; the city hosts the Poznań International Fair – the biggest industrial fair in Poland and one of the largest fairs in Europe. The city's most renowned landmarks include Poznań Town Hall, the National Museum, Grand Theatre, Poznań Cathedral and the Imperial Castle. Poznań is classified as a Gamma - global city by World Cities Research Network, it has topped rankings as a city with high quality of education and a high standard of living. It ranks in safety and healthcare quality; the city of Poznań has many times, won the prize awarded by "Superbrands" for a high quality city brand. In 2012, the Poznań's Art and Business Center "Stary Browar" won a competition organised by National Geographic Traveller and was given the first prize as one of the seven "New Polish Wonders".
The official patron saints of Poznań are Saint Peter and Paul of Tarsus, the patrons of the cathedral. Martin of Tours – the patron of the main street Święty Marcin is regarded as one of the patron saints of the city; the name Poznań comes from a personal name and would mean "Poznan's town". It is possible that the name comes directly from the verb poznać, which means "to get to know" or "to recognize," so it may mean "known town"; the earliest surviving references to the city are found in the chronicles of Thietmar of Merseburg, written between 1012 and 1018: episcopus Posnaniensis and ab urbe Posnani. The city's name appears in documents in the Latin nominative case as Posnania in 1236 and Poznania in 1247; the phrase in Poznan appears in 1146 and 1244. The city's full official name is Stołeczne Miasto Poznań, in reference to its role as a centre of political power in the early Polish state. Poznań is known as Posen in German, was called Haupt- und Residenzstadt Posen between 20 August 1910 and 28 November 1918.
The Latin names of the city are Civitas Posnaniensis. Its Yiddish name is Poyzn. In Polish, the city name has masculine grammatical gender. For centuries before the Christianization of Poland, Poznań was an important cultural and political centre of the Polan tribe. Mieszko I, the first recorded ruler of the Polans, of the early Polish state which they dominated, built one of his main stable headquarters in Poznań. Mieszko's baptism of 966, seen as a defining moment in the Christianization of the Polish state, may have taken place in Poznań. Following the baptism, construction began of the first in Poland. Poznań was the main seat of the first missionary bishop sent to Poland, Bishop Jordan; the Congress of Gniezno in 1000 led to the country's first permanent archbishopric being established in Gniezno, although Poznań continued to have independent bishops of its own. Poznań's cathedral was the place of burial of the early Piast monarchs, of Przemysł I and King Przemysł II; the pagan reaction that followed Mieszko II's death in 1034 left the region weak, in 1038, Duke Bretislaus I of Bohemia sacked and destroyed both Poznań and Gniezno.
Poland was reunited under Casimir I the Restorer in 1039, but the capital was moved to Kraków, unaffected by the troubles. In 1138, by the testament of Bolesław III, Poland was divided into separate duchies under the late king's sons, Poznań and its surroundings became the domain of Mieszko III the Old, the first of the Dukes of Greater Poland; this period of fragmentation lasted until 1320. Duchies changed hands. In about 1249, Duke Przemysł I began constructing what would become the Royal Castle on a hill on the left bank of the Warta. In 1253 Przemysł issued a charter to Thomas of Guben for the founding of a town under Magdeburg law, between the castle and the river. Thomas brought a large number of German settlers to aid in
Poland the Republic of Poland, is a country located in Central Europe. It is divided into 16 administrative subdivisions, covering an area of 312,696 square kilometres, has a temperate seasonal climate. With a population of 38.5 million people, Poland is the sixth most populous member state of the European Union. Poland's capital and largest metropolis is Warsaw. Other major cities include Kraków, Łódź, Wrocław, Poznań, Gdańsk, Szczecin. Poland is bordered by the Baltic Sea, Russia's Kaliningrad Oblast and Lithuania to the north and Ukraine to the east and Czech Republic, to the south, Germany to the west; the establishment of the Polish state can be traced back to AD 966, when Mieszko I, ruler of the realm coextensive with the territory of present-day Poland, converted to Christianity. The Kingdom of Poland was founded in 1025, in 1569 it cemented its longstanding political association with the Grand Duchy of Lithuania by signing the Union of Lublin; this union formed the Polish–Lithuanian Commonwealth, one of the largest and most populous countries of 16th and 17th century Europe, with a uniquely liberal political system which adopted Europe's first written national constitution, the Constitution of 3 May 1791.
More than a century after the Partitions of Poland at the end of the 18th century, Poland regained its independence in 1918 with the Treaty of Versailles. In September 1939, World War II started with the invasion of Poland by Germany, followed by the Soviet Union invading Poland in accordance with the Molotov–Ribbentrop Pact. More than six million Polish citizens, including 90% of the country's Jews, perished in the war. In 1947, the Polish People's Republic was established as a satellite state under Soviet influence. In the aftermath of the Revolutions of 1989, most notably through the emergence of the Solidarity movement, Poland reestablished itself as a presidential democratic republic. Poland is regional power, it has the fifth largest economy by GDP in the European Union and one of the most dynamic economies in the world achieving a high rank on the Human Development Index. Additionally, the Polish Stock Exchange in Warsaw is the largest and most important in Central Europe. Poland is a developed country, which maintains a high-income economy along with high standards of living, life quality, safety and economic freedom.
Having a developed school educational system, the country provides free university education, state-funded social security, a universal health care system for all citizens. Poland has 15 UNESCO World Heritage Sites. Poland is a member state of the European Union, the Schengen Area, the United Nations, NATO, the OECD, the Three Seas Initiative, the Visegrád Group; the origin of the name "Poland" derives from the West Slavic tribe of Polans that inhabited the Warta river basin of the historic Greater Poland region starting in the 6th century. The origin of the name "Polanie" itself derives from the early Slavic word "pole". In some languages, such as Hungarian, Lithuanian and Turkish, the exonym for Poland is Lechites, which derives from the name of a semi-legendary ruler of Polans, Lech I. Early Bronze Age in Poland begun around 2400 BC, while the Iron Age commenced in 750 BC. During this time, the Lusatian culture, spanning both the Bronze and Iron Ages, became prominent; the most famous archaeological find from the prehistory and protohistory of Poland is the Biskupin fortified settlement, dating from the Lusatian culture of the early Iron Age, around 700 BC.
Throughout the Antiquity period, many distinct ancient ethnic groups populated the regions of what is now Poland in an era that dates from about 400 BC to 500 AD. These groups are identified as Celtic, Slavic and Germanic tribes. Recent archeological findings in the Kujawy region, confirmed the presence of the Roman Legions on the territory of Poland; these were most expeditionary missions sent out to protect the amber trade. The exact time and routes of the original migration and settlement of Slavic peoples lacks written records and can only be defined as fragmented; the Slavic tribes who would form Poland migrated to these areas in the second half of the 5th century AD. Up until the creation of Mieszko's state and his subsequent conversion to Christianity in 966 AD, the main religion of Slavic tribes that inhabited the geographical area of present-day Poland was Slavic paganism. With the Baptism of Poland the Polish rulers accepted Christianity and the religious authority of the Roman Church.
However, the transition from paganism was not a smooth and instantaneous process for the rest of the population as evident from the pagan reaction of the 1030s. Poland began to form into a recognizable unitary and territorial entity around the middle of the 10th century under the Piast dynasty. Poland's first documented ruler, Mieszko I, accepted Christianity with the Baptism of Poland in 966, as the new official religion of his subjects; the bulk of the population converted in the course of the next few centuries. In 1000, Boleslaw the Brave, continuing the policy of his father Mieszko, held a Congress of Gniezno and created the metropolis of Gniezno and the dioceses of Kraków, Kołobrzeg, Wrocław. However, the pagan unrest led to the transfer of the capital to Kraków in 1038 by Casimir I the Restorer. In 1109, Prince Bolesław III Wrymouth defeated the King of Germany Henry V at the Battle of Hundsfeld, stopping the Ge
