Hazor is said to be the largest biblical-era site in Israel, and was once the ‘largest and most important city in the entire region,’ according to the Hebrew University of Jerusalem.
The ‘upper city’ was first settled in the third millennium BCE, during the Early Bronze Age, followed later by the lower city around the 18th century BCE.
It continued to expand until roughly the 13th century, at the end of the Late Bronze Age.
Then, the experts say it was ‘violently destroyed.’
Some experts suspect it may have been wiped out by Israelites, led by Joshua.
After winning the battle, Joshua ‘burned and ravaged the city.’
A Biblical narrative (Jos 11:10-12) describing the fall of the city pains a grisly picture of the aftermath of the battle:
‘And Joshua turned back at that time, and took Hazor, and smote its king with the sword: for Hazor formerly was the head of all those kingdoms. Everyone in it they put to the sword.
'They totally destroyed them, not sparing anything that breathed, and he burned up Hazor itself. Israel did not burn any of the cities built on their mounds - except Hazor.’
