Final answer:
Before his presidency, Jackson was a war hero and pushed for Indian removal. During his presidency, he reduced tariff rates, defended the preservation of the union, and worked to destroy the Second Bank of the United States.
Step-by-step explanation:
Before Andrew Jackson was elected as President of the United States, he accomplished two significant things. Firstly, he was a war hero who gained fame for his role in the War of 1812, particularly for his victory over the British at the Battle of New Orleans.
Secondly, he fought against the Creek Indians and successfully pushed for the Indian Removal Act of 1830, which led to the forced removal of Native American tribes from their ancestral lands.
During his presidency, Jackson achieved three notable accomplishments. Firstly, he reduced tariff rates through a compromise on the Tariffs of 1828 and 1832, thereby addressing concerns over high tariffs.
Secondly, he took a firm stance in favor of the preservation of the union when South Carolina attempted to nullify federal laws in the Nullification Crisis.
Lastly, Jackson worked to destroy the Second Bank of the United States, as he believed in a literal interpretation of the Constitution and wanted to limit the power of central banking.
