Then I asked it this:

"The rumors I've heard about this talk about how there was a people involved in this who were forced to adopt a religion to avoid being jailed or killed or something as a result of this kind of criminal behavior (the Kazarians, I guess), and opted for Judaism as part of that deal. Where is this idea coming from?"

The idea that there was once a people who were forced to adopt a religion—specifically Judaism—to avoid punishment for criminal behavior actually traces back to a mix of real medieval history and much later distortions.

Historically, this story comes from the Khazars, a multi-ethnic Turkic confederation that ruled a large area between the Black Sea, the Caspian Sea, and the Caucasus around the 7th–10th centuries. Several medieval Arabic and Jewish sources record that the Khazar ruling elite converted to Judaism sometime in the 8th or early 9th century. The most common version says the Khazar ruler invited representatives of Christianity, Islam, and Judaism to debate which religion was true. In the end, he chose Judaism because it didn’t tie the Khazars to either of their two powerful neighbors—the Christian Byzantine Empire or the Muslim Caliphate.

So, the conversion seems to have been primarily a political and diplomatic move, not something forced to escape legal punishment. It allowed the Khazar leadership to maintain independence in a volatile geopolitical region. Scholars differ on how widespread the conversion actually was. Many believe it was limited to the upper class or ruling family, while much of the population continued practicing local pagan or Tengrism traditions. Some later adopted Islam or Christianity.

There’s also ongoing debate over whether the conversion even happened on a large scale at all. A few modern historians (for example, Shaul Stampfer in a 2014 study) argue that the story might be exaggerated or even legendary, because there isn’t much archaeological evidence—only a handful of coins, letters, and mentions in foreign chronicles.

Centuries later, the story resurfaced in the 20th century when Arthur Koestler published The Thirteenth Tribe (1976), suggesting that the Khazar converts became the ancestors of many Ashkenazi Jews in Eastern Europe. That book was controversial and has been widely criticized by historians and geneticists, since modern DNA research shows little to no evidence supporting a large Khazar ancestry in Jewish populations.

In online or conspiratorial circles today, that old political conversion story often gets rewritten. People merge it with folklore or modern antisemitic conspiracy theories, saying that the Khazars were “criminals” or “name-stealers” who adopted Judaism as a disguise to avoid punishment or gain power. None of that is in the historical record. The “forced conversion to avoid execution or jail” part is completely speculative. It’s probably a fusion of several unrelated elements: the genuine Khazar conversion legend, medieval folktales about murderous innkeepers or impostors, and more modern conspiracy theories about hidden elites using religion as a cover.

So to sum up: • The Khazars were a real people whose leaders likely converted to Judaism in the 8th–9th century. • The motive was political independence, not a cover for criminal activity. • There’s no evidence they were “name stealers” or that they murdered travelers. • The “forced conversion to avoid punishment” version appears only in much later pseudohistorical and online conspiracy writings, not in any medieval or academic source.
