Harlem is a neighborhood in the New York City borough of Manhattan, which since the 1920s has been a major African-American residential, cultural and business center. Originally a Dutch village, formally organized in 1658, it is named after the city of Haarlem in the Netherlands. Harlem was annexed to New York City in 1873.

Harlem has been defined by a series of boom-and-bust cycles, with significant ethnic shifts accompanying each cycle. Black residents began to arrive en masse in 1904, with numbers fed by the Great Migration. In the 1920s and 1930s, the neighborhood was the focus of the "Harlem Renaissance", an outpouring of artistic and professional works without precedent in the American black community. However, with job losses in the time of the Great Depression and the deindustrialization of New York City after World War II, rates of crime and poverty increased significantly.

New York's revival in the late 20th century has led to renewal in Harlem as well. By 1995, Harlem was experiencing social and economic gentrification. Though the percentage of residents who are black peaked in 1950, the area remains predominantly black.

New York (/njuː ˈjɔrk/; locally IPA: [nɪu ˈjɔək] or [nuː ˈjɔɹk] ( listen)) is a state in the Northeastern region of the United States. New York is the 27th most extensive, the 3rd most populous, and the 7th most densely populated of the 50 United States. New York is bordered by New Jersey and Pennsylvania to the south, and by Connecticut, Massachusetts and Vermont to the east. The state has a maritime border with Rhode Island east of Long Island, as well as an international border with the Canadian provinces of Ontario to the west and north, and Quebec to the north. The state of New York is often referred to as New York State to distinguish it from New York City.

New York City, with a population of over 8.1 million, is the most populous city in the United States. Alone, it makes up over 40 percent of the population of New York state. It is known for its status as a center for finance and culture and for its status as the largest gateway for immigration to the United States. According to the U.S. Department of Commerce, New York City is also a destination of choice for many foreign visitors. Both the state and city were named for the 17th century Duke of York, James Stuart, future James II and VII of England and Scotland.

York (local ⁱ/ˈjɔːk/) is a walled city, situated at the confluence of the Rivers Ouse and Foss in North Yorkshire, England. The city has a rich heritage and has provided the backdrop to major political events throughout much of its two millennia of existence. The city offers a wealth of historic attractions, of which York Minster is the most prominent, and a variety of cultural and sporting activities.

The city was founded by the Romans in 71 AD, under the name of Eboracum. It became in turn the capital of the Roman province of Britannia Inferior, and of the kingdoms of Northumbria and Jorvik. In the Middle Ages, York grew as a major wool trading centre and became the capital of the northern ecclesiastical province of the Church of England, a role it has retained.

In the 19th century York became a hub of the railway network and a confectionery manufacturing centre. In recent decades, the economy of York has moved from being dominated by its confectionery and railway-related industries to one that provides services. The University of York and health services have become major employers, whilst tourism has become an important element of the local economy.
