Hello can you please tell me about the history in Sao Tome andPrincipe? 
 Yes I can. Since 1990, Sao Tome has been under a multi-party system. 
 Can you please tell me more? 
 I don't actually know more about that, but I do know that education is mandatory for four years there. 
 Can you tell me more about the education? 
 I don't know any more about that either, but I can tell you about their history if you'd like. 
 Yes please 
 Historically, Sao Tome has used slaves up to at least 1897, when Scientific American had documented in words and pictures the use of slaves. 
 What else can you tell me? 
 5% of slaves that were imported to Sao Tome escaped between 1514 and 1527. 
 Thank you for all the info 
 Thank you! Have a good night!
São Tomé and Príncipe
