Final answer:
Davy Crockett opposed the policies of President Andrew Jackson, especially his support for the Indian Removal Act of 1830.
Step-by-step explanation:
Davy Crockett, a well-known American frontiersman and politician, disagreed with the policies of President Andrew Jackson. Notably, Crockett opposed Jackson's stance on issues such as Indian Removal. This was a point of contention that contributed to Crockett's eventual departure from the Democratic Party, presided over by Jackson, and switch to the Whig Party, where he became a critic of Jackson’s administration.
Crockett was also known for his opposition to the Indian Removal Act of 1830, which sought to relocate Native American tribes from their ancestral homes in the southeastern United States to lands west of the Mississippi River, in a movement that became known as the Trail of Tears.
