Sources support that Old Believers fled after the 1666–67 schism to Don Cossack lands and allied with Cossack rebels, roughly two decades after the 1648 Khmelnytsky uprising. But they describe refuge and alliance rather than Old Believers becoming Cossacks, and one source describes the reverse flow, with many Cossacks becoming Old Believers.

What was said

… It's an ethno-national ideal informed by the Orthodox faith. Their own, um, don't think that, um, the Cossacks were not religious; they very much were, and in fact, once the Old Believers had to escape uh Moscow, uh, two decades later, they became Cossacks, so they even became today are an Old Believer, um, uh, movement. But not solely. Cossacks were never unified under one person, Klimonitski being an exception. …

What we found

Contradicts. Sources describe the conversion running the other way: many Cossacks who escaped Muscovite stratification became Old Believers, not Old Believers becoming Cossacks.[3]

Supports. After the 1666–67 Synod condemned them, Old Believers fled to the Don and other frontier areas, and in the 1660s–70s they sought refuge among Cossack bands.[1][4][5]

Supports. Old Believers joined with Don Cossacks in their rebellions against the Muscovite state, so the timing is roughly two decades after 1648.[2][6]

Context. No source describes Old Believers converting into Cossacks as an identity change. The post's 'they became Cossacks' is a loose characterization of refuge and alliance, and the claim departs from its wording only in that sense.[1][2][7]
