Why did Andrew Jackson claim that a "Corrupt Bargain" took place?

Andrew Jackson claimed that a "Corrupt Bargain" took place during the 1824 presidential election because he believed that John Quincy Adams had made a deal with Henry Clay to secure Clay's support in the House of Representatives, where the election was ultimately decided. Jackson believed that this deal involved promises of political favors or positions in exchange for Clay's support, which he viewed as unethical and corrupt. Jackson felt that the election had been stolen from him through backroom deals and political manipulation, leading him to label the situation as a "Corrupt Bargain."
