Nope. The name Hittites from the OT was applied to a formerly unknown, then-newly discovered civ, which was dramatically referred to as “The Forgotten Empire”.
Sounds like they share more than a name
Here is Grok’s conclusion…
“The Hittites in Deuteronomy 7:1 are likely a localized Canaanite group, possibly with cultural or ethnic ties to the Anatolian Hittites of Uşaklı Höyük, but not identical to them. The biblical Hittites were part of the Canaanite nations targeted for removal due to their idolatrous practices, as per the divine command to prevent cultural corruption. The Hittites of Uşaklı Höyük, as described in the article, represent the imperial Hittite civilization, whose influence reached Canaan but whose core was in Anatolia. While not the exact same group, the Canaanite Hittites in Deuteronomy may reflect a southern extension of this broader Hittite cultural sphere, as archaeological evidence suggests Hittite presence in Canaan during the relevant period.
“Ongoing DNA and paleobotanical studies at Uşaklı Höyük, as mentioned in the article, may further clarify the relationship between these populations, potentially revealing whether the Hittites in Canaan shared genetic or cultural markers with their Anatolian counterparts. For now, the connection is plausible but not definitive, as the biblical term likely applies to a localized subgroup within the broader Hittite cultural framework.
That is correct. The Hittite civilization proper collapsed around 1200 BC, about the time Israel were conquering Canaan. The Hittites mentioned in the Bible (like Uriah the Hittite) were most likely individual descendants of the Hittite empire. I remember reading recently that in the First Temple period, there was at least one village in Israel (in the Samaria region) that was populated by Hittites.
