This is an outline of the life and reign of Hezekiah King of Judah, from the biblical and Assyrian records. Hezekiah's rule is one which has been associated with significant chronological controversy, specifically a claimed 12-year gap if the biblical chronology is wrongly understood and correlated with the known chronology of Assyrian kings. This paper attempts to firmly lay out the chronology of this period from the details now available, aligning Hezekiah's accession to the throne to 716/15 B.C. during the reign of Sargon II of Assyria.
