The Kingdom of Judah (c.930 BC–586 BC), often known as the "Southern Kingdom, was one of the successor states to the "United Monarchy." The tribe of Judah elevated King David to rule over them, and the Davidic line survived for almost 350 years, until the Kingdom fell in 586 BCE to the Babylonian Empire under Nebuzar-adan, captain of Nebuchadnezzar's body-guard. This event coincided with the destruction of the First Temple of Jerusalem. Prior to this, several deportations of Judaean nobility and leading citizens occurred. After the overthrow of Babylonia by the Persian Empire, in 539 BCE the Persian ruler Cyrus the Great gave the Jews permission to return to the land that they came from, and more than 40,000 are said to have availed themselves of the privilege, as noted in the Biblical accounts of Jehoiakim, Ezra, and Nehemiah.
The Babylonian Captivity and the subsequent return to Israel were seen as one of the pivotal events in the drama between God and His people: Israel. Just as they had been predestined for, and saved from, slavery in Egypt, the Israelites were predestined to be punished by God through the Babylonians, and then saved once more. The Babylonian Captivity had a number of serious effects on Judaism and the Jewish culture, including changes to the Hebrew alphabet and changes in the fundamental practices and customs of the Jewish religion.
This period saw the last high-point of Biblical prophecy in the person of Ezekiel, followed by the emergence of the central role of the Torah in Jewish life. This process coincided with the emergence of scribes and sages as Jewish leaders (see Ezra and the Pharisees).
Prior to exile, the people of Israel had been organized according to tribe; afterwards, they were organized by clans, with only the tribe of Levi continuing in its special role. After the Babylonian captivity, there were always sizable numbers of Jews living outside Eretz Israel, thus marking one starting point of the "Jewish diaspora.
The Book of Jeremiah notes three deportations: The first was in the time of Jehoiachin, in 597 BC, when the Temple of Jerusalem was partially despoiled and a number of the leading citizens were removed (2 Kings 24:10-16) following the Siege and Fall of Jerusalem.
After the overthrow of Babylonia by the Persian Empire, in 537 BCE the Persian ruler Cyrus the Great gave the Jews permission to return to their native land, and more than 40,000 are said to have availed themselves of the privilege, as noted in the Biblical accounts of Ezra, and Nehemiah. The Persians had a different political philosophy of managing conquered territories than the Babylonians or Assyrians: under the Persians, local personages were put into power to govern the local populace.
The actual return of the exiles was consummated by Ezra, who assembled at the river Ahava all those desirous of returning. These consisted of about 1,800 men, or 5,500 to 6,000 souls (Ezra viii.), besides 38 Levites and 220 slaves of the Temple from Casiphia. With this body, which was invested with royal powers, Ezra and Nehemiah succeeded, after great difficulties, in establishing the post-exilic Jewish community. From the list given in Neh. vii. 6-73 (= Ezra ii.), which the chronicler erroneously supposed to be an enumeration of those who had returned under Cyrus, it appears that the whole Jewish community at this time comprised 42,360 men, or 125,000 to 130,000 souls.
Prior to the return, the northern Israelite tribes had been taken captive by Assyria and never returned, leaving the survivors of the Babylonian exile as the majority of the remaining Children of Israel. When the Israelites returned home, they found a mixture of peoples, the Samaritans, practicing a religion very similar, but not identical, to their own. Over time, hostility grew between the returning Jews and the Samaritans. According to the Bible, the Samaritans were foreign people settled into the area by the kings of Assyria and who had partially adopted the Israelite religion.
Although there are many other conflicting theories about the Samaritans' origins, many of them may have simply been Israelites who remained behind and thus had no part in the sweeping changes of the Israelite religion brought about among the captives. Alternatively, perhaps the fierce purity of the Jewish religion and cultural identity of the Babylonian Jews returning from exile, seventy years after their deportation, completely eclipsed the partial fate of the mixed group of Israelite survivors, who had practised paganism for hundreds of years in Israel (including the worship of a golden bull), and who had inter-married with the peoples sent into the territory by the Assyrians (a practice strictly forbidden by Mosaic laws, and punished by Nehemiah).
This period saw the last high-point of Biblical prophecy in the person of Ezekiel, followed by the emergence of the central role of the Torah in Jewish life; according to many historical-critical scholars, it was edited and redacted during this time, and saw the beginning of the canonization of the Bible, which provided a central text for Jews.
This process coincided with the emergence of scribes and sages as Jewish leaders (see Ezra and the Pharisees). Prior to exile, the people of Israel had been organized according to tribe; afterwards, they were organized by clans, only the tribe of Levi continuing in its 'special role'. After this time, there were always sizable numbers of Jews living outside Eretz Israel; thus, it also marks the beginning of the "Jewish diaspora", unless this is considered to have begun with the Assyrian Captivity of Israel.
In Rabbinic literature, Babylon is a metaphor for the current Jewish diaspora.
