The United States of America (USA), commonly referred to as the United States (US), America, or simply the States, is a federal republic consisting of 50 states, 16 territories, a federal district, and various overseas extraterritorial jurisdictions. The 48 contiguous states and the federal district of Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The country also has five populated and nine unpopulated territories in the Pacific and the Caribbean. At 3.79 million square miles (9.83 million km2) in total and with around 316 million people, the United States is the fourth-largest country by total area and third largest by population. 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 is also extremely diverse, and it is home to a wide variety of wildlife.
Paleo-indians migrated from Asia to what is now the US mainland around 15,000 years ago, with European colonization beginning in the 16th century. The United States emerged from 13 British colonies located along the Atlantic seaboard. Disputes between Great Britain and these colonies led to the American Revolution. On July 4, 1776, delegates from the 13 colonies unanimously issued the Declaration of Independence. The ensuing war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire. The current Constitution was adopted on September 17, 1787. The first 10 amendments, collectively named the Bill of Rights, were ratified in 1791 and guarantee many fundamental civil rights and freedoms.
The history of the United States as covered in American schools and universities typically begins with either Christopher Columbus's 1492 voyage to the Americas or with the prehistory of the Native peoples, with the latter approach having become increasingly common in recent decades.
Indigenous peoples lived in what is now the United States for thousands of years and developed complex cultures before European colonists began to arrive, mostly from England, after 1600. The Spanish had early settlements in Florida and the Southwest, and the French along the Mississippi River and Gulf Coast. By the 1770s, thirteen British colonies contained two and a half million people along the Atlantic coast, east of the Appalachian Mountains. The colonies were prosperous and growing rapidly, and had developed their own autonomous political and legal systems. After driving the French out of North America in 1763, the British imposed a series of new taxes while rejecting the American argument that taxes required representation in Parliament. "No taxation without representation" became the American catch phrase. Tax resistance, especially the Boston Tea Party of 1774, led to punishment by Parliament designed to end self-government in Massachusetts. All 13 colonies united in a Congress that led to armed conflict in April 1775. On July 4, 1776, the Congress adopted the Declaration of Independence drafted by Thomas Jefferson, proclaimed that all men are created equal, and founded a new nation, the United States of America.
The Articles of Confederation, formally the Articles of Confederation and Perpetual Union, was an agreement among the 13 founding states that established the United States of America as a confederation of sovereign states and served as its first constitution. Its drafting by the Continental Congress began in mid-1776, and an approved version was sent to the states for ratification in late 1777. The formal ratification by all 13 states was completed in early 1781. Even when not yet ratified, the Articles provided domestic and international legitimacy for the Continental Congress to direct the American Revolutionary War, conduct diplomacy with Europe and deal with territorial issues and Native American relations. Nevertheless, the weakness of the government created by the Articles became a matter of concern for key nationalists. On March 4, 1789, the Articles were replaced with the U.S. Constitution. The new Constitution provided for a much stronger national government with a chief executive (the president), courts, and taxing powers.
Canadian Confederation (French: Confédération canadienne) was the process by which the federal Dominion of Canada was formed on July 1, 1867. On that day, three British colonies became four provinces of the new dominion. The existing Province of Canada was divided into the new provinces of Ontario and Quebec, and two other colonies, New Brunswick and Nova Scotia, also became provinces of the Dominion of Canada.
The Constitution of the State of Maine established the "State of Maine" in 1820 and is the fundamental governing document of the state. It consists of a Preamble and ten Articles (divisions), the first of which is a "Declaration of Rights".
In particular, the Maine constitution was written:
The Constitution of the State of New Hampshire is the fundamental law of the State of New Hampshire, with which all statute laws must comply. The constitution became effective June 2, 1784, when it replaced the state's constitution of 1776.
The constitution is divided into two parts: a Bill of Rights and a Form of Government. Subsections of each part are known as articles. For example, the subsection dealing with free speech and liberty of the press is cited as "Part I, Article 22" or "Pt. I, Art. 22."
