Hasidic communities are groups within the Jewish tradition that emphasize mysticism, spirituality, and a close-knit communal lifestyle. Originating in the 18th century in Eastern Europe, they follow the teachings of Hasidism, which focuses on joy, prayer, and a personal relationship with God. These communities often maintain distinct cultural practices, including traditional dress and specific religious customs. They are typically led by a Rebbe, a spiritual leader who guides followers in both religious and everyday matters. Hasidic communities can be found worldwide, with significant populations in places like New York and Israel.
