Final answer:
Andrew Jackson contributed to Manifest Destiny through policies towards Native Americans, the acquisition of Florida, and advancements in transportation.
Step-by-step explanation:
In the context of Manifest Destiny, Andrew Jackson contributed to the expansionist goals of the United States in a few ways. First, Jackson's policies and actions with regards to Native American tribes, such as the Indian Removal Act of 1830, forced many Native Americans from their ancestral lands and opened up vast territories for white settlement. This expansion of American territory was a key component of the Manifest Destiny ideology.
Furthermore, Jackson's presidency saw the acquisition of Florida from Spain through the Adams-Onís Treaty in 1819. This added more land to the United States and helped pave the way for future territorial acquisitions in the west.
Lastly, Jackson's presidency coincided with significant advancements in transportation, such as the construction of the Erie Canal. These transportation improvements made it easier for settlers to migrate westward, facilitating the spread of American influence and control over new territories.
