Hasid

Hasid (Hebrew: חסיד, "pious"; plural חסידים "Hasidim") is a Jewish honorific, frequently used as a term of exceptional respect in the Talmudic and early medieval periods. In classic Rabbinic literature it differs from "Tzadik" ("righteous") by instead denoting one who goes beyond the legal requirements of ritual and ethical Jewish observance in daily life. The literal meaning of "Hasid" derives from Chesed ("kindness"), the outward expression of love for God and other people. This spiritual devotion motivates pious conduct beyond everyday limits. The devotional nature of its description lent itself to a few Jewish movements in history being known as "Hasidim". Two of these derived from the Jewish mystical tradition, as it could tend towards piety over legalism.

As a personal honorific, both "Hasid" and "Tzadik" could be applied independently to the same individual with both different qualities. The 18th-century Vilna Gaon, for instance, at that time the chief opponent of the new Jewish mystical movement that became known as "Hasidism", was renowned for his righteous life. In tribute to his scholarship, he became popularly honored with the formal title of "Genius", while amongst the Hasidic movement's leadership, despite his fierce opposition to their legalistic tendencies, he was respectfully referred to as "The Gaon, the Hasid from Vilna".

In the aggregate, it may refer to members of any of the following Jewish movements:

• the Hasideans of the Maccabean period, around the 2nd century BCE
• the Ashkenazi Hasidim, an ascetic German mystical-ethical movement of the 12th and 13th centuries
• Hasidic Judaism, a movement which began in Ukraine in the 18th century
