Plantations and slavery
Oak Hill Mansion
Monroe sold his small Virginia plantation in 1783 to enter law and politics. Although he owned multiple properties over the course of his lifetime, his plantations were never profitable. Although he owned much more land and many more slaves, and speculated in property, he was rarely on site to oversee the operations. Overseers treated the slaves harshly to force production, but the plantations barely broke even. Monroe incurred debts by his lavish and expensive lifestyle and often sold property (including slaves) to pay them off.
