You're welcome

You're welcome.  I'm glad you liked the changes.  I don't know much about the subject, but an expert has said he would look at the article this weekend.  So hopefully that will bring more insight to the article.  It's a bit complicated because the topic includes various ancient empires, the Persian people, Persia, and then Iran (which is a nation that has not existed for very long as it is presently defined).  So for example Timur seems to hve been very brutal, as you state, and yet adopted some Persian customs.  So did slavery under his reign mean there was slavery in Iran? Or was this an example of the enslavement of Iran?  I don't know.  Cheers.  Thank you for your comment.
