Sabbatai Zevi

In the year 1666, more than HALF the Jews of Europe followed the largest messiah movement in Jewish history.
Sabbatai Zevi turned Europe into Sodom and Gomorrah.
It's where that popular 666 number comes from.
No more fasting, 10 commandments, no more fasting, all decency went out the window. Jacob Frank declared himself the reincarnation of Sabbatai Levi.
