Stylized, high-contrast illustration of medieval armored horsemen in red and green tones, riding with weapons raised. Bold white text on a black bar across the center reads “THE KHAZAR THEORY.”

Earlier this year, a cluster of high-profile influencers began using terms such as “Khazarian mafia” and referring to all Jews as “Khazars.” This language that quickly spread across X draws on a fringe conspiracy theory rooted in a much older historical debate about the origins of Ashkenazi Jews.  The Khazar hypothesis of Ashkenazi ancestry is the historically debated idea that a substantial portion of Ashkenazi Jews descend not from ancient Israelites of the Levant, but from the […]
