Judaism can be understood as both a religion and an ethnicity. It involves belief in one God, a shared history and homeland, sacred texts like the Torah and Talmud, and common rituals, foods, and culture. There are various Jewish ethnic groups including Ashkenazi, Sephardi, Mizrahi, and Ethiopian Jews. While Judaism has religious aspects like laws and practices, it also encompasses shared languages, culture, art, and history. Today, Jewish civilization is centered in Israel, Europe, and North America, especially in large cities, where Jews from different Jewish movements and backgrounds continue to evolve their religious and cultural traditions.
