435 DATE OF THE COMING OF THE MESSIAH
R. Judah HaNasi predicted that the Messiah would come in this year (365 years after the destruction of the Temple). R. Hanina, his student, predicted that the Messiah would come in the year 470 (400 years after the destruction). This, coupled with persecution and natural disasters, resulted in the appearance of false messiahs. This phenomenon became so widespread that most rabbis forbade predictions of the coming of the Messiah, since often people bereft of hope would convert after grave disappointment.
438 - 527 MONOPHYSITE DISAGREEMENT (Eretz Israel)
