Here is a link to a presentation (formatted as a PDF) I gave at the Abigail Adams Institute on October 26, 2018.
The presentation discussed the relevance of Islam and the Ottoman empire to the early Reformation and Counter-Reformation.

Below are the maps and graphs produced for and used in the presentation:
