The rise of the Tea Party movement in the United States was primarily sparked by widespread discontent over government spending, taxation, and perceived overreach by the federal government. Established in 2009, the movement was a response to the economic policies of President Barack Obama's administration, particularly the financial stimulus packages and healthcare reforms. Tea Party activists advocated for limited government, reduced taxes, and strict adherence to the U.S. Constitution. This grassroots movement played a significant role in shaping American political discourse, galvanizing conservative voters, and influencing elections, particularly during the 2010 midterm elections.
