Slave resistance took various forms from passive to active, but was not always effective in improving treatment or reducing profits. Passive resistance included acts like working slowly, while active resistance involved damaging crops or running away. Resistance sometimes succeeded by cutting into an owner's profits or leading them to offer better treatment. However, resistance regularly failed due to threats of punishment, increased mistreatment, slave hunters who would capture runaways, geographic limitations, divisions between slaves, and owners having greater resources like weapons. Ultimately, the slave trade continued for centuries, showing that resistance generally did not overcome the system of slavery.
