In 1808 Napoleon issued 3 decrees against the Jews in France after having convened the Sanhedrin and having issued an invitation to all the synagogues in Europe to send delegates.

Where can I find the most detailed work where someone has written about this matter?

I would like to know why Napoleon began this process of convening the Sanhedrin and why he later chose to just issue the decrees that he did?

I've read what is on wikipedia, but I would like much more detail.
