Final answer:
Between 1810 and 1860, the free black population in Louisiana experienced a significant increase due to factors such as manumission and migration from other places. Louisiana had the largest number of free black people in the South during this time.
Step-by-step explanation:
Between 1810 and 1860, the free black population in Louisiana did increase dramatically. During this period, Louisiana experienced a significant growth in its free black population. In fact, Louisiana had the largest number of free black people in the South, with many residing in the upper southern states such as Louisiana, Virginia, Maryland, and North Carolina.
Several factors contributed to the increase in the free black population. One major factor was manumission, or the formal granting of freedom to enslaved people. The ideals of equality and freedom that emerged during the American Revolution led some slaveholders to release the people they enslaved.
Furthermore, Louisiana had a significant number of free black people prior to the 1803 Louisiana Purchase, and others came from places like Cuba and Haiti. Overall, the free black population in Louisiana experienced a dramatic increase during the period between 1810 and 1860.
