Why has slavery increased since the eighteen hundreds?

Slavery has not increased since the 1800s in a legal sense, as it was abolished in many countries during that period. However, forms of modern slavery, such as human trafficking, forced labor, and exploitation, have become more prevalent due to globalization, poverty, and conflict. These factors create vulnerabilities that traffickers exploit, leading to an increase in illegal and exploitative practices resembling historical slavery. Awareness and efforts to combat these issues have grown, but they remain significant challenges worldwide.
