Libertarianism in the United States is a movement promoting individual liberty and minimized government. Although the word libertarian continues to be widely used to refer to socialists internationally, its meaning in the United States has deviated from its political origins. The Libertarian Party asserts the following to be core beliefs of libertarianism:
Libertarians support maximum liberty in both personal and economic matters. They advocate a much smaller government; one that is limited to protecting individuals from coercion and violence. Libertarians tend to embrace individual responsibility, oppose government bureaucracy and taxes, promote private charity, tolerate diverse lifestyles, support the free market, and defend civil liberties.
Through 20 polls on this topic spanning 13 years, Gallup found that voters who are libertarian on the political spectrum ranged from 17–23% of the US electorate. This includes members of the Republican Party (especially Libertarian Republicans), Democratic Party, Libertarian Party, and Independents.
Libertarianism, like many other concepts, predates the official coinage of that word. In the US the general movement started, philosophically, with the founding of the country itself, which was based on classical liberal ideas, which came to be known in the 20th century US as libertarianism. The ideas of John Locke, fundamental to those of the Founding Fathers, are considered a starting point for libertarian thought. Minarchists like Thomas Jefferson and Thomas Paine, influenced by Locke, advocated positions that are not only compatible with modern American libertarianism, but are also considered foundations for that movement.
