Although the Western slave trade stands out for its brutal effectiveness, slavery was commonplace around the world. Around 1800, an estimated 75% of the earth's population was stuck in some form of slavery. Also, slavery is still alive and well in many parts of the world. So much has yet to be done to end the practice once and for all.
In the image above we see a 13th century image of a Yemen slave market by al-Wasiti in a text called Maqamat. The Maqamat is one the most beautiful manuscripts from the Islamic world and can be found online in the Bibliotheque Nationale de France (well worth a look! Add a comment below if you took the time to do so!).
