Enlightenment ideas in the mid to late 1700s influence reform movements that challenged existing notions of social relations and could be used to explain what trend in the graph? 1. Decrease in slave transport in the early 1800s when slavery was outlawed by some countries
2. Lack of transport of slaves to Spanish mainland from 1650 to the 700s because Spain was the heart of the enlightenment
3. Decrease in deaths in transit in the early 1800s because enlightenment thought gave slaves hope and prevented mutiny
4. Increase in slave transport to Brazil in the early 1800s because slaves flock to Brazil to seek religious refuge from Enlightenment thought
