John Adams (October 30, 1735 July 4, 1826) was an American statesman, attorney, diplomat, writer, and Founding Father who served as the second president of the United States from 1797 to 1801. Before his presidency, he was a leader of the American Revolution that achieved independence from Great Britain and during the war, served as a diplomat in Europe. He was twice elected vice president, serving from 1789 to 1797 in a prestigious role with little power. Adams was a dedicated diarist and regularly corresponded with many important contemporaries, including his wife and adviser Abigail Adams as well as his friend and rival Thomas Jefferson.

A lawyer and political activist prior to the Revolution, Adams was devoted to the right to counsel and presumption of innocence. He defied anti-British sentiment and successfully defended British soldiers against murder charges arising from the Boston Massacre. Adams was a Massachusetts delegate to the Continental Congress and became a leader of the revolution. He assisted Jefferson in drafting the Declaration of Independence in 1776. As a diplomat in Europe, he helped negotiate a peace treaty with Great Britain and secured vital governmental loans. Adams was the primary author of the Massachusetts Constitution in 1780, which influenced the United States constitution, as did his essay Thoughts on Government.

Adams was elected to two terms as vice president under President George Washington and was elected as the United States' second president in 1796. He was the only president elected under the banner of the Federalist Party. During his single term, Adams encountered fierce criticism from the Jeffersonian Republicans and from some in his own Federalist Party, led by his rival Alexander Hamilton. Adams signed the controversial Alien and Sedition Acts and built up the Army and Navy in the undeclared naval war (called the "Quasi-War") with France. During his term, he became the first president to reside in the executive mansion now known as the White House.

In his bid for reelection, opposition from Federalists and accusations of despotism from Jeffersonians led to Adams losing to his vice president and former friend Jefferson, and he retired to Massachusetts. He eventually resumed his friendship with Jefferson by initiating a correspondence that lasted fourteen years. He and his wife generated a family of politicians, diplomats, and historians now referred to as the Adams political family, which includes their son John Quincy Adams, the sixth president of the United States. John Adams died on July 4, 1826 the fiftieth anniversary of the adoption of the Declaration of Independence hours after Jefferson's death. Adams and his son are the only presidents of the first twelve who never owned slaves. Surveys of historians and scholars have favorably ranked his administration.

The Continental Congress was a series of legislative bodies, with some executive function, for thirteen of Britain's colonies in North America, and the newly declared United States just before, during, and after the American Revolution. The term "Continental Congress" most specifically refers to the First and Second Congresses of 1774–1781 and may also refer to the Congress of the Confederation of 1781–1789, which operated as the first national government of the United States until being replaced under the Constitution of the United States. Thus, the term covers the three congressional bodies of the Thirteen Colonies and the new United States that met between 1774 and 1789.

The First Continental Congress was called in 1774 in response to growing tensions between the colonies culminating in the passage of the Intolerable Acts by the British Parliament. It met for about six weeks and sought to repair the fraying relationship between Britain and colonies while asserting the rights of colonists. The Second Continental Congress convened in 1775 in response to the breakout of hostilities in Massachusetts. Soon after meeting, this second Congress sent the Olive Branch Petition to King George III while also selecting George Washington as the head of the new Continental Army. After peace was not forthcoming, the same congress drafted and adopted the Declaration of Independence in July 1776, proclaiming that the former colonies were now independent sovereign states.

The Second Continental Congress served as the provisional government of the U.S. for most of the War of Independence. In March 1781, the nation's first Frame of Government, the Articles of Confederation, came into force, at which time the body became the Congress of the Confederation. This unicameral governing body would convene in eight sessions before disbanding in 1789, when the 1st United States Congress under the new Constitution of the United States took over the role as the nation's legislative branch of government.

Both the First and Second Continental Congresses convened in Philadelphia, though with the city's capture during the Revolutionary War, the Second Congress was forced to meet in other locations for a time. The Congress of Confederation was also established in Philadelphia and later moved to New York City when it briefly became the U.S. capital beginning in 1785.

Much of what is known today about the daily activities of these congresses come from the journals kept by the secretary for all three congresses, Charles Thomson. Printed contemporaneously, the Papers of the Continental Congress contain the official congressional papers, letters, treaties, reports and records. The delegates to the Continental and Confederation congresses had extensive experience in deliberative bodies, with "a cumulative total of nearly 500 years of experience in their Colonial assemblies, and fully a dozen of them had served as speakers of the houses of their legislatures."
