John Adams was the second president of the United States, serving from 1797 to 1801. He was a founding father of the country and played a key role in the drafting of the Declaration of Independence. Adams was a Federalist and believed in a strong central government, which led to tensions with the Democratic-Republican controlled Congress. Despite his efforts to pass important legislation, such as the Alien and Sedition Acts, his presidency was marked by political polarization and he was not re-elected. Adams is remembered for his strong leadership and commitment to the principles of liberty and democracy.
