Final answer:
The Corrupt Bargain refers to the deal that resolved the 1824 presidential election deadlock, resulting in John Quincy Adams becoming president after Henry Clay supported him in the House of Representatives vote.
Step-by-step explanation:
The deal that broke the election deadlock of 1824 is referred to as the Corrupt Bargain. This term describes the alleged political agreement between presidential candidates John Quincy Adams and Henry Clay. After no candidate secured a majority of the Electoral College votes, the decision went to the House of Representatives.
Henry Clay, who was the Speaker of the House at the time and also a candidate, threw his support behind Adams. When Adams won the presidency, he appointed Clay as his Secretary of State, which was at the time considered a stepping stone to the presidency. This action raised suspicions and led Andrew Jackson supporters to claim that a corrupt bargain had taken place. As a result of the "corrupt bargain," John Quincy Adams became president.
