The Tea Party movement was an American fiscally conservative political movement within the Republican Party that began in 2007, catapulted into the mainstream by Congressman Ron Paul's presidential campaign. The movement expanded in response to the policies of Democratic president Barack Obama and was a major factor in the 2010 wave election in which Republicans gained 63 House seats and took control of the U.S. House of Representatives.
Participants in the movement called for lower taxes and for a reduction of the national debt and federal budget deficit through decreased government spending. The movement supported small-government principles and opposed the Affordable Care Act (also known as Obamacare), President Obama's signature health care legislation. The Tea Party movement has been described as both a popular constitutional movement and as an "astroturf movement" purporting to be spontaneous and grassroots, but alleged to have been influenced by outside interests. The movement was composed of a mixture of libertarian, right-wing populist, and conservative activism. It sponsored multiple protests and supported various political candidates since 2009. The movement took its name from the December 1773 Boston Tea Party, a watershed event in the American Revolution, with some movement adherents using Revolutionary era costumes.
