Final answer:
The Coyne affair stemmed from the implementation of John Quincy Adams becoming president following the 'corrupt bargain' of the 1824 presidential election.
Step-by-step explanation:
The Coyne affair resulted from the implementation of John Quincy Adams becoming president, an outcome linked to the controversial event known as the "corrupt bargain." In the "corrupt bargain", which took place after the 1824 presidential election, no candidate received a majority of electoral votes, thereby throwing the election to the House of Representatives. It was widely believed that Henry Clay used his influence as Speaker of the House to secure the presidency for Adams in exchange for being appointed as Secretary of State, which was commonly the stepping stone to the presidency at that time. This action sparked considerable controversy and led to a rift within the Democratic-Republican Party, eventually contributing to the formation of new political parties.
