Read the excerpt by former enslaved person Olaudah Equiano. The closeness of the place, and the heat of the climate, added to the number in the ship, which was so crowded that each had scarcely room to turn himself, almost suffocated us.

We were conducted immediately to the merchant's yard, where we were all pent up together like so many sheep in a fold [pen], without regard to sex or age.

What was an effect of Equiano speaking about his experience?

Abolitionists rallied to improve the treatment of slaves.
Slavers were enraged by the loss of lives caused by the poor conditions.
Enslaved people staged violent shipboard revolts against slave ship crews.
Politicians worked to create guidelines for transportation of enslaved people.
