AP World History: Ottomans

So I can't get the video to work as an upload.  So instead check out this 10 minute video on youtube about how Mehmed II conquers Constantinople (and think about taking a class with the UMass professor...) (If the link doesn't work, the video is called "Islam--Empire of Faith III--The Ottomans--part 2") and read pages 762-770 in the text book.
