The conditions on slave ships were despicable. The slave traders and buyers all thought of the slaves as animals so didn’t care about the conditions they lived on the 3 month journey. The slaves were made to sitting their own dirt and blood and the journey often made the slaves sea sick so they were also sitting in amongst their own sick.
The traders just thought of the slaves as cargo. The slaves were squashed into tiny spaces, because the more slaves on the ship the more money could be made. The slaves were either tightly packed , as mentioned above, or , to stop spread of disease they were spread out more so that more slaves survived the journey because the risk with tight packing was that more slaves died during the duration of the journey.
When the slaves arrived at the end of the journey they were scrubbed extremely hard to remove layers of skin to make them look healthier. Hannah
