New York, often called New York City or simply NYC, is the most populous city in the United States located at the southern tip of New York State on one of the world's largest natural harbors. The city comprises five boroughs, each of which is coextensive with a respective county. It is a global city and a cultural, financial, high-tech, entertainment, and media center with a significant influence on commerce, health care, scientific output, life sciences, research, technology, education, politics, tourism, dining, art, fashion, and sports. Home to the headquarters of the United Nations, New York is an important center for international diplomacy, and it is sometimes described as the world's most important city and the capital of the world.
In the pre-Columbian era, the area of present-day New York City was inhabited by Algonquians, including the Lenape. Their homeland, known as Lenapehoking, included the present-day areas of Staten Island, Manhattan, the Bronx, the western portion of Long Island (including Brooklyn and Queens), and the Lower Hudson Valley. The first documented visit into New York Harbor by a European was in 1524 by Italian Giovanni da Verrazzano, an explorer from Florence in the service of the French crown. He claimed the area for France and named it Nouvelle Angoulême (New Angoulême). A Spanish expedition, led by the Portuguese captain Estêvão Gomes sailing for Emperor Charles V, arrived in New York Harbor in January 1525 and charted the mouth of the Hudson River, which he named Río de San Antonio ('Saint Anthony's River').
