The United States of America (USA), commonly referred to as the United States (U.S.) or America, is a federal republic composed of 50 states, a federal district, five major territories and various possessions. The 48 contiguous states and Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is in the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The territories are scattered about the Pacific Ocean and the Caribbean Sea. At 3.8 million square miles (9.842 million km2) and with over 320 million people, the country is the world's third or fourth-largest by total area and the third most populous. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States are also extremely diverse, and the country is home to a wide variety of wildlife.
The United States of America is a federal republic consisting of 50 states, a federal district (where the nation's seat of government–Washington, D.C.–is located), five major territories, and various possessions.

States are the primary subdivisions of the United States, and possess a number of powers and rights under the United States Constitution, such as regulating intrastate commerce, running elections, creating local governments, and ratifying constitutional amendments. Each state has its own constitution, grounded in republican principles, and government, consisting of three branches: executive, legislative, and judicial. All states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state is represented by two Senators, while Representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census. Additionally, each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the President of the United States, equal to the total of Representatives and Senators in Congress from that state.Article IV, Section 3, Clause 1 of the Constitution grants to Congress the authority to admit new states into the Union. Since the establishment of the United States in 1776, the number of states has expanded from the original 13 to 50. Each new state has been admitted on an equal footing with the existing states.
United States usually refers to the United States of America, a country in North America.

A National Historic Site (NHS) is a protected area of national historic significance in the United States. An NHS usually contains a single historical feature directly associated with its subject. A related but separate designation, the National Historical Park (NHP), is an area that generally extends beyond single properties or buildings, and its resources include a mix of historic and sometimes significant natural features.
As of 2015, there are 50 NHPs and 90 NHSs. Most NHPs and NHSs are managed by the National Park Service (NPS). Some federally designated sites are privately owned, but are authorized to request assistance from the NPS as affiliated areas. One property, Grey Towers National Historic Site, is managed by the U.S. Forest Service.
As of October 15, 1966, all historic areas, including NHPs and NHSs, in the NPS are automatically listed on the National Register of Historic Places (NRHP). There are also about 80,000 NRHP sites, the large majority of which are neither owned nor managed by the NPS. Of these, about 2,500 have been designated at the highest status as National Historic Landmark (NHL) sites.

National Historic Sites of Canada (French: Lieux historiques nationaux du Canada) are places that have been designated by the federal Minister of the Environment on the advice of the Historic Sites and Monuments Board of Canada (HSMBC), as being of national historic significance.Parks Canada, a federal agency, manages the National Historic Sites program. As of 2015, there are 973 National Historic Sites, 168 of which are administered by Parks Canada; the remainder are administered and/or owned by other levels of government or private entities. The sites are located across all ten provinces and three territories, with two sites located in France (the Beaumont-Hamel Newfoundland Memorial and Canadian National Vimy Memorial).
There are related federal designations for National Historic Persons and National Historic Events.
Emerging Canadian nationalist sentiment in the late 19th century and early 20th century led to an increased interest in preserving Canada's historic sites. There were galvanizing precedents in other countries. With the support of notables such as Victor Hugo and Eugène Viollet-le-Duc, the Commission des monuments historique was created in France in 1837, and it published its first list of designated sites, containing 934 entries, in 1840. In the United Kingdom, the National Trust for Places of Historic Interest or Natural Beauty was created in 1894 to protect that country's historic and natural heritage. While there was no National Park Service in the United States until 1916, battlefields of the Civil War were designated and managed by the War Department: Chickamauga and Chattanooga (created 1890), Antietam (1890), Shiloh (1894), Gettysburg (1895), Vicksburg (1899), and Chalmette (1907).
SS United States is a luxury passenger liner built in 1952 for United States Lines designed to capture the trans-Atlantic speed record.
Built at a cost of $79.4 million ($724 million in today's dollars) the ship is the largest ocean liner constructed entirely in the U.S. and the fastest ocean liner to cross the Atlantic in either direction. Even in her retirement, she retains the Blue Riband, the accolade given to the passenger liner crossing the Atlantic Ocean in regular service with the highest speed.
Her construction was subsidized by the U.S. government, since she was designed to allow conversion to a troopship should the need arise.United States operated uninterrupted in transatlantic passenger service until 1969. Since 1996 she has been docked at Pier 82 on the Delaware River in Philadelphia.
Inspired by the exemplary service of the British liners RMS Queen Mary and Queen Elizabeth, which transported hundreds of thousands of U.S. troops to Europe during World War II, the U.S. government sponsored the construction of a large and fast merchant vessel that would be capable of transporting large numbers of soldiers. Designed by renowned American naval architect and marine engineer William Francis Gibbs (1886–1967), the liner's construction was a joint effort between the United States Navy and United States Lines. The U.S. government underwrote $50 million of the $78 million construction cost, with the ship's operators, United States Lines, contributing the remaining $28 million. In exchange, the ship was designed to be easily converted in times of war to a troopship with a capacity of 15,000 troops, or to a hospital ship .
