What group developed a mixed culture while living among the Israelite's?

The Samaritans are the group that developed a mixed culture while living among the Israelites. Historically, they emerged after the Assyrian conquest of the northern kingdom of Israel in the 8th century BCE, when foreign populations settled in the region and intermarried with the remaining Israelite inhabitants. This led to a syncretic culture that blended aspects of Israelite religion and local pagan practices, resulting in distinct religious beliefs and customs. The Samaritans continue to identify themselves as descendants of the ancient Israelites, maintaining their own version of the Torah and unique religious traditions.
