Hezekiah witnessed the forced resettlement of the northern Kingdom of Israel by Sargon's Assyriansin c 720 BC and was king of Judah during the invasion and siege of Jerusalem by Sennacherib in 701 BC. The siege was lifted by a miraculous plague that afflicted Sennacherib's army. Even so, the Assyrians conquered much of Judah, and Hezekiah's people came to yearn for an ideal king who would restore the golden age of David.
Notably, Isaiah and Micah prophesied during his reign. Hezekiah enacted sweeping religious reforms, during which he removed non-Yahwistic elements from the Jerusalem temple. In 701 BC, King Hezekiah of Judah, backed by Egypt, revolts against King Sennacherib of Assyria. Sennacherib sacks many Palestinian cities, but fails in his attempt to take Jerusalem.
