Sabbatai Zevi in the late 18th century

Actually Shabtai Tzvi lived in the late 17th century.

The migration of Jews to secularism began with the French Revolution, Napoleon's "New Sanhedrin" and the 19th century Emancipation.

Thanks, Alouette, yes, that's what I should have said, and of course it puts it earlier than those revolutions I mentioned. Back to the period coming out of the Anabaptist revolution of Muenster in Germany and the Puritan Revolution of 1640-1660 in England.

It was a tragic story of confusion and disillusionment for many of the Jews of that time.

As you say, it was mostly the French revolutionaries who added the secular element. The American revolution was much more compatible with religion.

P.S. My great-great grandfather was heavily involved in the revolution 0f 1848, which attempted to overthrow the Hapsburg Austro-Hungarian Empire. He fled from Hungary to London after it failed, along with Kossuth.
