Yair Davidiy is an Israeli researcher, author, and speaker best known for his work on the Lost Ten Tribes of Israel and their possible migrations into Western nations. He is the founder of Brit-Am Hebrew Nations, an organization dedicated to researching biblical, historical, and linguistic evidence related to the identity and whereabouts of the tribes exiled by the Assyrian Captivity of Israel.

Davidiy’s research draws extensively on the Hebrew Bible, classical historical sources, archaeology, and cultural traditions to explore how the descendants of the northern tribes may have moved through regions such as the Caucasus Mountains and eventually settled among Western peoples. His work often focuses on identifying links between the ancient Israelites and populations in Europe and related nations.

Among his well-known books are Origin: Lost Ten Tribes in the West According to the Prophets and History, The Tribes, and New Joseph: USA, where he examines biblical prophecy concerning the tribes of Ephraim and Manasseh, and their potential historical fulfillment among modern nations. Through articles, books, and videos, Davidiy seeks to reconnect biblical prophecy with historical developments and to encourage renewed study of Israelite identity in world history.

Yair Davidiy’s work has gained international attention among readers interested in biblical prophecy, the history of the Israelites, and the continuing influence of ancient Israel on the development of Western civilization.
