Sabbatai Zevi was a Jewish scholar from Smyrna in the Ottoman Empire who had made private claims to messiahship for years before they reached a wide public. Those claims gained a mass following only after 1665, when Nathan of Gaza, a younger scholar who became his chief prophet and interpreter, proclaimed him publicly as the Messiah, turning a private conviction into a movement almost overnight.
News of the proclamation spread rapidly through Jewish communities across Europe, North Africa and the Middle East, carried by the existing networks of correspondence and travel that connected the diaspora. The year 1666 came to be widely anticipated as the year of national deliverance and return to the land of Israel, an expectation specific enough in its timing that many communities disrupted their ordinary religious and economic life in preparation for it.
The speed and geographic reach of that response, gathering momentum across three continents within a single year of Nathan of Gaza's proclamation, marked Sabbatai Zevi's movement as one of the largest messianic mobilizations in Jewish history up to that point, built on a claim Zevi himself had held privately for years before anyone beyond his own circle knew of it.
