An urban area is a human settlement with a high population density and an infrastructure of built environment. Urban areas originate through urbanization, and researchers categorize them as cities, towns, conurbations or suburbs. In urbanism, the term "urban area" contrasts to rural areas such as villages and hamlets; in urban sociology or urban anthropology, it often contrasts with natural environment.

The development of earlier predecessors of modern urban areas during the urban revolution of the 4th millennium BCEled to the formation of human civilization and ultimately to modern urban planning, which along with other human activities such as exploitation of natural resources has led to a human impact on the environment.

The United Nations (UN) is a global intergovernmental organization established by the signing of the UN Charter on 26 June 1945 with the articulated mission of maintaining international peace and security, to develop friendly relations among states, to promote international cooperation, and to serve as a centre for harmonizing the actions of states in achieving those goals.

The United Nations headquarters is located in New York City, with several other offices located in Geneva, Nairobi, Vienna, and The Hague. The UN comprises six principal organizations: the General Assembly, the Security Council, the Economic and Social Council, the International Court of Justice, the Secretariat, and the Trusteeship Council which, together with several specialized agencies and related agencies, make up the United Nations System. There are in total 193 member states and 2 observer states.

A central business district (CBD) is the commercial and business center of a city. It contains commercial space and offices, and in larger cities will often be described as a financial district. Geographically, it often coincides with the "city centre" or "downtown". However, these concepts are not necessarily synonymous: many cities have a central business district located away from its traditional city center, and there may be multiple CBDs within a single urban area. The CBD will often be highly accessible and have a large variety and concentration of specialised goods and services compared to other parts of the city.

In Chicago, the Chicago Loop is the second-largest central business district in the United States. It is also referred to as the core of the city's downtown.

A metropolis is a large city or conurbation which is a significant economic, political, and cultural area for a country or region, and an important hub for regional or international connections, commerce, and communications.

A big city belonging to a larger urban agglomeration, but which is not the core of that agglomeration, is not generally considered a metropolis but a part of it. The plural of the word is metropolises, although the Latin plural is metropoles, from the Greek metropoleis (μητρoπόλεις).

The New York metropolitan area, also called the Tri-State area and sometimes referred to as Greater New York or Metro New York, is the largest metropolitan economy in the world, with a gross metropolitan product of over US$2.6 trillion. It is also the largest metropolitan area in the world by urban landmass, encompassing 4,669.0 sq mi (12,093 km). Among the most populous metro areas in the world, New York is the largest metropolitan statistical area in the United States and the only one with more than 20 million residents, according to the 2020 U.S. Census.

The core of this vast area, the New York metropolitan statistical area, includes New York City and much of Downstate New York (Long Island as well as the mid- and lower Hudson Valley), northern and central New Jersey (including that state's eleven largest municipalities), and Southwestern Connecticut. The phrase Tri-State area is used to refer to the larger urbanized area of Downstate New York, northern New Jersey, and western Connecticut. The urban region's combined statistical area, the New York–Newark, NY–NJ–CT–PA combined statistical area, spans four states.

Manhattan is the most densely populated and geographically smallest of the five boroughs of New York City. Coextensive with New York County, Manhattan is the smallest county by area in the U.S. state of New York. Located almost entirely on Manhattan Island near the southern tip of the state, Manhattan is centrally located in the Northeast megalopolis and the urban core of the New York metropolitan area. Manhattan serves as New York City's economic and administrative center and has been described as the cultural, financial, media, and entertainment capital of the world.

Present-day Manhattan was originally part of Lenape territory. European settlement began with the establishment of a trading post by Dutch colonists in 1624 on Manhattan Island; the post was named New Amsterdam in 1626. The territory came under English control in 1664 and was renamed New York after King Charles II of England granted the lands to his brother, the Duke of York. New York, based in present-day Lower Manhattan, served as the capital of the United States from 1785 until 1790. The Statue of Liberty in New York Harbor greeted millions of arriving immigrants in the late 19th century and is a world symbol of the United States and its ideals. Manhattan became a borough during the consolidation of New York City in 1898, and houses New York City Hall, the seat of the city's government. Harlem in Upper Manhattan became the center of what is now known as the cultural Harlem Renaissance in the 1920s. The Stonewall Inn in Greenwich Village, part of the Stonewall National Monument, is considered the birthplace in 1969 of the modern gay-rights movement, cementing Manhattan's central role in LGBTQ culture. Manhattan was the site of the original World Trade Center, which was destroyed during the September 11 terrorist attacks in 2001.

In urban planning, a historic core city or central city is the municipality with the largest 1940 population in the present metropolitan area (metropolitan statistical area). This term was retired by the US census bureau and replaced by the term principal city, which can include historic core cities and post-WWII cities. Metropolitan areas were no longer considered monocentric, but polycentric due to suburbanization of employment. A historic core city is not to be confused with the core of a metropolitan area which is defined as an urban area with a population of over 50,000 by the US census bureau.

Historic core cites in the United States often have higher detached single family housing rates, lower density, and fewer jobs than surrounding satellite cities and suburbs. A central city is usually the first settlement established in an urban region, years before the outlying districts came into existence. These cities typically contain less economic activity and more crime than their surrounding areas. Central cities often form the regional downtowns of metro areas. The term is used mainly in US context, although since the 1970s it has also become relatively common in Canada and, to a lesser extent, Europe and Australia.

The Dallas–Fort Worth metroplex, officially designated Dallas–Fort Worth–Arlington by the U.S. Office of Management and Budget, is the most populous metropolitan statistical area in the U.S. state of Texas and the Southern U.S., encompassing 11 counties. Its historically dominant core cities are Dallas and Fort Worth. It is the economic and cultural hub of North Texas. Residents of the area also refer to it as DFW (the code for Dallas Fort Worth International Airport) or the Metroplex. The Dallas–Fort Worth–Arlington metropolitan statistical area's population was 7,637,387 according to the U.S. Census Bureau's 2020 census, making it the fourth-largest metropolitan area in the U.S. and the eleventh-largest in the Americas. In 2016, the Dallas–Fort Worth metroplex had the highest annual population growth in the United States. By 2023, the U.S. Census Bureau estimated that the Dallas-Fort Worth metropolitan area's population had increased to 8,100,037, with the highest numerical growth of any metropolitan area in the United States. By 2025, NCTCOG estimated that the Dallas-Fort Worth metropolitan area's population had increased to around 8,578,654 million residents, making the Dallas-Fort Worth metropolitan area around 1.42 million residents from becoming a megacity.

The metropolitan region's economy, also referred to as Silicon Prairie, is primarily based on banking, commerce, insurance, telecommunications, technology, energy, healthcare, medical research, transportation, manufacturing, and logistics. As of 2022, Dallas–Fort Worth is home to 23 Fortune 500 companies, the 4th-largest concentration of Fortune 500 companies in the United States behind New York City (62), Chicago (35), and Houston (24). In 2016, the metropolitan economy surpassed Houston, the second largest metro area in Texas, to become the fourth-largest in the U.S. The Dallas–Fort Worth metroplex boasted a GDP of just over $620.6 billion in 2020 (although both metropolitan regions have switched places multiple times since GDP began recording). If the Metroplex were a sovereign state, it would have the twentieth largest economy in the world as of 2019. In 2015, the conurbated metropolitan area would rank the ninth-largest economy if it were a U.S. state. In 2020, Dallas–Fort Worth was recognized as the 36th best metropolitan area for STEM professionals in the U.S.

A master's degree (from Latin magister) is a postgraduate academic degree awarded by universities or colleges upon completion of a course of study demonstrating mastery or a high-order overview of a specific field of study or area of professional practice. A master's degree normally requires previous study at the bachelor's level, either as a separate degree or as part of an integrated course. Within the area studied, master's graduates are expected to possess advanced knowledge of a specialized body of theoretical and applied topics; high order skills in analysis, critical evaluation, or professional application; and the ability to solve complex problems and think rigorously and independently.

Henry Oliver Walker (May 14, 1843 – January 14, 1929) was an American painter of figures and portraits best known for his mural decorations. His works include a series of paintings honoring various poets for the Library of Congress and decorations for public buildings such as the Appellate Court House in New York City, Bowdoin College in Maine, the Massachusetts State House, the Minnesota State Capitol, and the Court House in Newark, New Jersey.

A treasure binding or jewelled bookbinding is a luxurious book cover using metalwork in gold or silver, jewels, or ivory, perhaps in addition to more usual bookbinding material for book covers such as leather, velvet, or other cloth. The actual bookbinding technique is the same as for other medieval books, with the folios, normally of vellum, stitched together and bound to wooden cover boards. The metal furnishings of the treasure binding are then fixed, normally by tacks, onto these boards. Treasure bindings appear to have existed from at least Late Antiquity, though there are no surviving examples from so early, and Early Medieval examples are very rare. They were less used by the end of the Middle Ages, but a few continued to be produced in the West even up to the present day, and many more in areas where Eastern Orthodoxy predominated. The bindings were mainly used on grand illuminated manuscripts, especially gospel books designed for the altar and use in church services, rather than study in the library.

The vast majority of these bookbindings were later destroyed as their valuable gold and jewels were removed by looters, or the owners when in need of cash. Others survive without their jewels, and many are either no longer attached to a book, or have been moved to a different book. Some survive in major libraries; for example, the Morgan Library in New York City, the John Rylands Library in Manchester, the British Library in London, the Bayerische Staatsbibliothek in Munich and the Bibliothèque Nationale in Paris. As the carved ivory reliefs often used could not usually be recycled, these survive in much larger numbers, giving a better idea of the numbers of treasure bindings that once existed. Other examples are recorded in documentary sources but though the books survive the covers do not. The Book of Kells lost its binding after a robbery, and the fate of the missing cover of the Book of Lindisfarne is not recorded.

A global city (also known as a power city, world city, alpha city, or world center) is a city that serves as a primary node in the global economic network. The concept originates from geography and urban studies, based on the thesis that globalization has created a hierarchy of strategic geographic locations with varying degrees of influence over finance, trade, and culture worldwide. The global city represents the most complex and significant hub within the international system, characterized by links binding it to other cities that have direct, tangible effects on global socioeconomic affairs.

The criteria of a global city vary depending on the source. Common features include a high degree of urban development, a large population, the presence of major multinational companies, a significant and globalized financial sector, a well-developed and internationally linked transportation infrastructure, local or national economic dominance, high quality educational and research institutions, and a globally influential output of ideas, innovations, or cultural products. Global city rankings are numerous. New York City, London, Tokyo, and Paris are the most commonly mentioned.

Saskia Sassen (born January 5, 1947) is a Dutch-American sociologist noted for her analyses of globalization and international human migration. She is a professor of sociology at Columbia University in New York City, and the London School of Economics. The term global city was coined and popularized by Sassen in her 1991 work The Global City: New York, London, Tokyo.

In Christianity, salvation (also called deliverance or redemption) is the saving of human beings from sin and its consequences—which include death and separation from God—by Christ's death and resurrection, and the justification entailed by this salvation.

The idea of Jesus's death as an atonement for human sin was recorded in the Christian Bible, and was elaborated in Paul's epistles and in the Gospels. Paul saw the faithful redeemed by participation in Jesus's death and rising. Early Christians regarded themselves as partaking in a new covenant with God, open to both Jews and Gentiles, through the sacrificial death and subsequent exaltation of Jesus Christ.

The headquarters of the United Nations (UN) is on 17 to 18 acres (6.9 to 7.3 ha) of grounds in the Turtle Bay neighborhood of Midtown Manhattan in New York City. It borders First Avenue to the west, 42nd Street to the south, 48th Street to the north, and the East River to the east. Completed in 1952, the complex consists of several structures, including the Secretariat, Conference, and General Assembly buildings, and the Dag Hammarskjöld Library. The complex was designed by a board of architects led by Wallace Harrison and built by the architectural firm Harrison & Abramovitz, with final projects developed by Oscar Niemeyer and Le Corbusier. The term Turtle Bay is occasionally used as a metonym for the UN headquarters or for the United Nations as a whole.

The headquarters holds the seats of the principal organs of the UN, including the General Assembly and the Security Council, but excluding the International Court of Justice, which is seated in The Hague. The United Nations has three additional subsidiary regional headquarters or headquarters districts. These were opened in Geneva (Switzerland) in 1946, Vienna (Austria) in 1980, and Nairobi (Kenya) in 1996. These adjunct offices help represent UN interests, facilitate diplomatic activities, and enjoy certain extraterritorial privileges, but do not contain the seats of major organs.

United Nations specialized agencies are autonomous organizations working with the United Nations (UN) and each other through the structure of the United Nations Economic and Social Council at the intergovernmental level, and through the Chief Executives Board for Coordination (CEB) at the intersecretariat level.

One of the principal objectives of the UN is to solve economic, social, cultural and humanitarian issues through international cooperation. Several specialized agencies have been set up to achieve these goals, agencies which may or may not have been created by the UN, but were incorporated into the United Nations System by the United Nations Economic and Social Council acting under Articles 57 and 63 of the United Nations Charter. At present, the UN has in total 15 specialized agencies that carry out various functions on behalf of the UN. The specialized agencies are listed below.
