at each other. Planting career and slavery Jackson resigned his judgeship in 1804. He had almost gone bankrupt when the credit he used for land speculation collapsed in the wake of an earlier financial panic. He had to sell Hunters Hill, as well as of land he bought for speculation, and bought a smaller plantation near Nashville that he would call the Hermitage. He focused on recovering from his losses by becoming a successful planter and merchant. The Hermitage would grow to , making it one of the largest cotton-growing plantations in the state. Like most planters in the Southern United States, Jackson used slave labor. In 1804, Jackson had nine African American slaves; by 1820, he had over 100; and by his death in 1845, he had over 150. Over his lifetime, he owned a total of 300 slaves. Jackson subscribed to the paternalistic idea of slavery, which claimed that slave ownership was morally acceptable as long as slaves were treated with humanity and their basic needs were cared for. In practice, slaves were treated as a form of wealth whose productivity needed to be protected. Slaves who disobeyed or ran away could be harshly punished. For example, in an 1804 advertisement to recover a runaway slave, Jackson offered "ten dollars extra, for every hundred lashes any person will give him, to the amount of three hundred". Jackson also participated in the local slave trade. Over time, his accumulation of wealth in both slaves and land placed him among the elite families of Tennessee.

They had gotten into an argument over a horse race, and Dickinson allegedly uttered a slur against Rachel. During the duel, Dickinson fired first, and the bullet hit Jackson in the chest. The wound was not life-threatening because the bullet had shattered against his breastbone. Jackson returned fire and killed Dickinson. The killing tarnished Jackson's reputation. Later in the year, Jackson became involved in former vice president Aaron Burr's plan to conquer Spanish Florida and drive the Spanish from Texas. Jackson had first gotten to know Burr in 1805 when he stayed with the Jacksons at the Hermitage during a tour of what was then the Western United States that he had embarked on after mortally wounding Alexander Hamilton in the Burr–Hamilton duel. Burr eventually persuaded Jackson to
