Moses ben Jacob Cordovero, (1522–1570), is a leading Jewish mystic in 16th-century Safed.

He is known by the acronym the Ramak.

After the Medieval circles of Kabbalah, centered around the Zohar, attempts are made to give a complete intellectual system to its theology.

Influenced by the earlier success of Jewish philosophy in articulating a rational study of Jewish thought, Moshe Cordovero produces the first accepted, complete systemization of the profound ideas of Kabbalah.

His rational school of Cordoveran Kabbalah represents one of the pivotal developments in the historical evolution of Kabbalah.

Immediately after him in Safed, Isaac Luria articulates a subsequent, successive paradigm for Kabbalistic theology, with new revealed doctrines and organization of previous Kabbalistic thought.
