Judaism is an ancient monotheistic religion that originated in West Asia during the Bronze Age. It traces its origins and laws to the Torah, the most important text for Jews which contains the Five Books of Moses. The three key figures in establishing Judaism were Abraham, Isaac, and Jacob. Jews follow a set of religious laws and rituals outlined in the Torah and oral traditions, including observance of the Sabbath and Jewish holidays, dietary restrictions, and worship at synagogues. There are various denominations of Judaism that have developed over time in response to historical and cultural changes.
