Lyndon Baines Johnson / / (August 27, 1908 – January 22, 1973), often referred to as LBJ, was the 36th President of the United States (1963–1969), a position he assumed after his service as the 37th Vice President of the United States (1961–1963). He is one of only four people who served in all four elected federal offices of the United States: Representative, Senator, Vice President, and President. Johnson, a Democrat from Texas, served as a United States Representative from 1937 to 1949 and as a Senator from 1949 to 1961, including six years as United States Senate Majority Leader, two as Senate Minority Leader and two as Senate Majority Whip. After campaigning unsuccessfully for the Democratic nomination in 1960, Johnson was asked by John F. Kennedy to be his running mate for the 1960 presidential election.
Johnson succeeded to the presidency following the assassination of John F. Kennedy on November 22, 1963, completed Kennedy's term and was elected President in his own right, winning by a large margin over Barry Goldwater in the 1964 election. Johnson was greatly supported by the Democratic Party and as President, he was responsible for designing the "Great Society" legislation that included laws that upheld civil rights, public broadcasting, Medicare, Medicaid, environmental protection, aid to education, and his "War on Poverty." Johnson was renowned for his domineering personality and the "Johnson treatment," his coercion of powerful politicians in order to advance legislation.
The President of the United States of America (POTUS) is the head of state and head of government of the United States. The president leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces.
Article II of the U.S. Constitution vests the executive power of the United States in the president and charges him with the execution of federal law, alongside the responsibility of appointing federal executive, diplomatic, regulatory, and judicial officers, and concluding treaties with foreign powers, with the advice and consent of the Senate. The president is further empowered to grant federal pardons and reprieves, and to convene and adjourn either or both houses of Congress under extraordinary circumstances. Since the founding of the United States, the power of the president and the federal government have grown substantially and each modern president, despite possessing no formal legislative powers beyond signing or vetoing congressionally passed bills, is largely responsible for dictating the legislative agenda of his party and the foreign and domestic policy of the United States. The president is frequently described as the most powerful person in the world.
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.
