Firstly, Finkelstein, Litt, and Langgut’s findings from the Sea of Galilee show that there was an intense dry period in Canaan between c. 1250 BC (when Hazor fell) and c. 1100 BC or just before (when Canaan experienced a baby boom). Secondly, the authors show that these findings can also be connected with the peak of the so-called “Minoan Warming” in this graph. Thirdly, the authors show that all the textual evidence supports their hypothesis that the 14th century BC was a wet period with no known major droughts while the 13th-12th centuries BC were a dry period with many known major droughts. The authors, however, show no real evidence of “economic and demographic decline” in Canaan in the Late Bronze IIB-III, which they claim occurred. Though Hazor, Bethel, and Shechem did lose their city-state status in the 13th century BC (Bethel later than the other two), I find the claim that either the population or economy of Canaan declined during the 13th century BC to be dubious.
Paradoxically, Finkelstein flip-flops again on the date of the beginning of Israelite settlement, placing it in the midst of the drought instead of, as he did in 2006, after the end of it. If cities like Megiddo, Ashdod, Ashkelon, Lachish, and Azekah could prosper in the Late Bronze IIB, so they could trade imported Egyptian grain with the nomads Finkelstein claims settled down during this era. It is doubtful that Israelite settlements in the Late Bronze IIB-III could survive the coercive power of Egyptian soldiers and taxmen. Like Todd Bolen and Israel Finkelstein in 2006, I see no evidence Israelite settlement predates the collapse of Egyptian rule in Canaan. In any case, it is impossible that “demographic decline” (which probably didn’t happen) could somehow spur a settlement boom in the highlands of Canaan.
