Between the 16th and 19th Centuries, hundreds of thousands of Europeans were captured by pirates known as the Barbary corsairs. Many spent the rest of their lives in slavery in North Africa. We hear the account of one English boy, Thomas Pellow, who was a slave of the Moroccan Sultan, Moulay Ismail, for 23 years.
