The Ottomans, Safavids and Mughals

1.  The reason for the textbook to group the Ottomans, the Safavids and the Mughals is becuase they all had the same Islamic religion.  That is the main reason but also the three groups have other similarities that would make it beneficial to group them together.  This was good decision in the sense that you could see the similarities of the different groups right together and in line.  Personally for me I like things being clearly separate and more easily to distinguish between, that way there is no confusion. 
2.This period of global interactions was in my opinion a good one.  Like everything there are bad things too but the good things make the bad things seem less negative.  Some of the good things about this time period was the productive trading and trade routes established.  This was not only helpful for that time period but also for future time periods.  The slavery during this time period was helpful and very good, even though it is not a good thing it was helpful for trading and the people at the time.
