The movement began following Barack Obama's first presidential inauguration (in January 2009) when his administration announced plans to give financial aid to bankrupt homeowners.
 A major force behind it was Americans for Prosperity (AFP), a conservative political advocacy group founded by businessmen and political activist David H. Koch.
 It is unclear exactly how much money is donated to AFP by David and his brother Charles Koch.
 Following a February 19, 2009 call by CNBC reporter Rick Santelli on the floor of the Chicago Mercantile Exchange for a "tea party," over fifty conservative activists agreed by conference call to coalesce against Obama's agenda and scheduled series of protests, including the 2009 Taxpayer March on Washington.
 Supporters of the movement subsequently have had a major impact on the internal politics of the Republican Party.
 Although the Tea Party is not a party in the classic sense of the word, some research suggests that members of the Tea Party Caucus vote like a significantly farther right third party in Congress.
The Chestertown Tea Party was a protest against British excise duties which, according to local legend, took place in May 1774 in Chestertown, Maryland as a response to the British Tea Act.
 Chestertown tradition holds that, following the example of the more famous Boston Tea Party, colonial patriots boarded the brigantine "Geddes" in broad daylight and threw its cargo of tea into the Chester River.
 The event is celebrated each Memorial Day weekend with a festival and historic reenactment called the Chestertown Tea Party Festival.
The Hawaii Tea Party are regional grassroots affiliates with the Tea Party each of which are broken down into seven smaller parties Hilo Tea Party Patriots (Hilo), Honolulu Professionals for Change (Honolulu), Kauai TEA Party (Kauai) Kona TEA Party (Kona), Maui Tea Party (Maui) Oahu Tea Party (Ewa Beach) Tea Party Wahiawa (Wahiawa).
The Tea Party Caucus (TPC) is a congressional caucus of conservative members of the Republican Party in the United States House of Representatives.
 The Caucus was founded in July 2010 by Minnesota Congresswoman Michele Bachmann who was its first chair.
 From July 2012 to April 2013 the Tea Party Caucus neither met nor posted news on its webpage, leading observers to describe it as "dead," "inactive," and "defunct."
 In April 2013, Mick Mulvaney of South Carolina filed paperwork to create a new Tea Party Caucus, but found that Bachmann intended to continue the caucus, starting with an event on April 25, 2013.
 On June 19, 2014, Tea Party Caucus member Steve Scalise of Louisiana was elected as the House Majority Whip.
 The Caucus was reconstituted in the 114th Congress in January 2015.
 Rep. Tim Huelskamp of Kansas became the chair in February 2015.
 Huelskamp lost party primary election in 2016.
 The Caucus is now largely inactive.
 Though the primary functions of the Caucus have varied from year to year, its members have promoted budget cuts, including significant cuts in non-defense spending and adherence to the movement's interpretation of the Constitution.
 The caucus's members have also advocated socially conservative legislation, supported the right to keep and bear arms, and promoted limited government.

The Boston Tea Party was a political protest by the Sons of Liberty in Boston, Massachusetts, on December 16, 1773.
 The demonstrators, some disguised as Native Americans, in defiance of the Tea Act of May 10, 1773, destroyed an entire shipment of tea sent by the East India Company.
 They boarded the ships and threw the chests of tea into Boston Harbor.
 The British government responded harshly and the episode escalated into the American Revolution.
 The Tea Party became an iconic event of American history, and since then other political protests such as the Tea Party movement have referred to themselves as historical successors to the Boston protest of 1773.
