According to the Hebrew Bible, the United Monarchy was established under Saul and continued under King David and Solomon with its capital in Jerusalem. After Solomon's reign, the nation split into two kingdoms, the Kingdom of Israel (in the north) and the Kingdom of Judah (in the south). The Kingdom of Israel was conquered by the Assyrian ruler Sargon II in the late 8th century BCE with many people from the capital Samaria being taken captive to Media and the Khabur River valley. The Kingdom of Judah continued as an independent state until it was conquered by a Babylonian army in the early 6th century BCE, destroying the First Temple that was at the center of ancient Jewish worship. The Judean elite was exiled to Babylonia and this is regarded as the first Jewish Diaspora. Later many of them returned to their homeland after the subsequent conquest of Babylonia by the Persians seventy years later, a period known as the Babylonian Captivity. A new Second Temple was constructed, and old religious practices were resumed.
