Biblical Judaism developed around the 10th century BC, when Solomon built the Temple in Jerusalem and placed the Ark of the Covenant there. The prophets played an important role in the continuation of Judaism, exhorting the Israelites to remain faithful to the covenant they had made with God.
Thanks to the prophets and the priests who preserved the tradition, the destruction of the Temple by the Babylonians and the Babylonian captivity did not lead to the decline of Judaism, but to its transformation into a religion that was practiced regardless of the territory in which its followers lived.
