Philadelphia in the context of "U.S. Route 1"

A city centre, also known as an urban core, is the commercial, cultural and often the historical, political, and geographic heart of a city. The term "city centre" is primarily used in British English, and closely equivalent terms that exist in other languages, such as "centre-ville" in French, Stadtzentrum in German, or shìzhōngxīn (市中心) in Chinese. In the United States, the term "downtown" is generally used, though a few cities, like Philadelphia, use the term "Center City" or "City Center".

Washington, D.C., officially the District of Columbia and commonly known as simply Washington or D.C., is the capital city and federal district of the United States. The city is separated from Virginia to its southwest by the Potomac River and shares land borders with Maryland to its north and east. It was named after George Washington, a Founding Father and the first president of the United States. The district is named for Columbia, the female personification of the nation.

The U.S. Constitution in 1789 called for the creation of a federal district under exclusive jurisdiction of the U.S. Congress. As such, Washington, D.C., is not part of any state, and is not one itself. The Residence Act, adopted on July 16, 1790, approved the creation of the capital district along the Potomac River, and is considered the city's founding date. In 1800, when the capital was moved from Philadelphia, the 6th Congress started meeting in the then-unfinished Capitol Building, and the second president, John Adams, moved into the newly finished White House. In 1801, the District of Columbia, formerly part of Maryland and Virginia and including the existing settlements of Georgetown and Alexandria, was officially made the federal district; initially, the city was a separate settlement within the larger district. In 1846, Congress reduced the size of the district when it returned the land Virginia had ceded, including the city of Alexandria. In 1871, it made the entire district into a single municipality. There have been several failed efforts to make the district into a state since the 1880s, including a statehood bill that passed the House of Representatives in 2021 but was not adopted by the U.S. Senate.

The Constitution of the United States is the supreme law of the United States of America. It superseded the Articles of Confederation, the nation's first constitution, on March 4, 1789. Originally including seven articles, the Constitution defined the foundational structure of the federal government.

The drafting of the Constitution by many of the nation's Founding Fathers, often referred to as its framing, was completed at the Constitutional Convention, which assembled at Independence Hall in Philadelphia between May 25 and September 17, 1787. Influenced by English common law and the Enlightenment liberalism of philosophers like John Locke and Montesquieu, the Constitution's first three articles embody the doctrine of the separation of powers, in which the federal government is divided into the legislative, bicameral Congress; the executive, led by the president; and the judiciary, within which the Supreme Court has apex jurisdiction. Articles IV, V, and VI embody concepts of federalism, describing the rights and responsibilities of state governments, the states in relationship to the federal government, and the process of constitutional amendment. Article VII establishes the procedure used to ratify the constitution.

Puerto Rican Spanish is the variety of the Spanish language as characteristically spoken in Puerto Rico and by millions of people of Puerto Rican descent living in the United States and elsewhere. It belongs to the group of Caribbean Spanish variants and, as such, is largely derived from Canarian Spanish and Andalusian Spanish. Outside of Puerto Rico, the Puerto Rican accent of Spanish is also commonly heard in the U.S. Virgin Islands and many U.S. mainland cities like Orlando, New York City, Philadelphia, Miami, Tampa, Boston, Cleveland, and Chicago, among others. However, not all stateside Puerto Ricans have knowledge of Spanish. Opposite to island-born Puerto Ricans who primarily speak Spanish, many stateside-born Puerto Ricans primarily speak English, although many stateside Puerto Ricans are fluent in Spanish and English, and often alternate between the two languages.

A warehouse is a building for storing goods. Warehouses are used by manufacturers, importers, exporters, wholesalers, transport businesses, customs, etc. They are usually large plain buildings in industrial parks on the outskirts of cities, towns, or villages.

Warehouses usually have loading docks to load and unload goods from trucks. Sometimes warehouses are designed for the loading and unloading of goods directly from railways, airports, or seaports. They often have cranes and forklifts for moving goods, which are usually placed on ISO standard pallets and then loaded into pallet racks. Stored goods can include any raw materials, packing materials, spare parts, components, or finished goods associated with agriculture, manufacturing, and production.

Baltimore is the most populous city in the U.S. state of Maryland. It is the 30th-most populous U.S. city with a population of 585,708 at the 2020 census and estimated at 568,271 in 2024, while the Baltimore metropolitan area at 2.86 million residents is the 22nd-largest metropolitan area in the nation. The city is also part of the Washington–Baltimore combined statistical area, which had a population of 9.97 million in 2020. Baltimore was designated as an independent city by the Constitution of Maryland in 1851. Though not located under the jurisdiction of any county in the state, it forms part of the Central Maryland region together with the surrounding county that shares its name.

The land that is present-day Baltimore was once used as hunting ground by Paleo-Indians. In the early 1600s, the Susquehannock began to hunt there. People from the Province of Maryland established the Port of Baltimore in 1706 to support the tobacco trade with Europe and established the Town of Baltimore in 1729. During the American Revolutionary War, the Second Continental Congress briefly moved its deliberations to the Henry Fite House from December 1776 to February 1777 prior to the capture of Philadelphia to British troops, which permitted Baltimore to serve briefly as the nation's capital before it returned to Philadelphia. The Battle of Baltimore was pivotal during the War of 1812, culminating in the British bombardment of Fort McHenry, during which Francis Scott Key wrote a poem that became "The Star-Spangled Banner", which was designated as the national anthem in 1931. During the Pratt Street Riot of 1861, the city was the site of some of the earliest violence associated with the American Civil War.
