Step-by-step explanation:
The two important events that shaped the election of 1800 were:
- Failed negotiations with France
- Formation of two major political parties
Failed negotiations with France, known as the XYZ Affair, contributed to strained relations between the United States and France. This event heightened anti-French sentiments and caused a shift in public opinion towards the Federalist Party, led by John Adams. The formation of two major political parties, the Federalist Party and the Democratic-Republican Party, represented the growing political divide in the country and had a significant influence on the election of 1800.
