== Americas == 

 I suggest an excerpt from; and link to;  to correct a glaring omission in the Americas section, which starts rather inappropriately with African-European slave trading and frankly is a mess anyway. 

 In the Pre-Columbian Americas slavery was widespread, with warring tribes commonly enslaving captives and some tribes even specializing in slave raiding and trading, including trading with early European colonizers. 

  
 Best of luck to anyone accepting this request.
