After the Battle of Carchemish in 605 BCE, King Nebuchadnezzar of Babylon besieged Jerusalem, resulting in tribute being paid by King Jehoiakim.[1] Jehoiakim refused to pay tribute in Nebuchadnezzar's fourth year, which led to another siege in Nebuchadnezzar's seventh year, culminating with the death of Jehoiakim and the exile to Babylonia of King Jeconiah, his court and many others; Jeconiah's successor Zedekiah and others were exiled in Nebuchadnezzar's 18th year; a later deportation occurred in Nebuchadnezzar's 23rd year. The dates, numbers of deportations, and numbers of deportees given in the biblical accounts vary.[2] These deportations are dated to 597 BCE for the first, with others dated at 587/586 BCE, and 582/581 BCE respectively.[3]
After the fall of Babylon to the Persian king Cyrus the Great in 539 BCE, exiled Judeans were permitted to return to Judah.[4][5] According to the biblical book of Ezra, construction of the Second Temple in Jerusalem began around 537 BCE.
