The Old Believers aren't what you typically picture when we talk about tribes cut off from society. This band of Russian nonconformists separated from the Russian Orthodox Church in 1666, protesting changes that were introduced by Patriarch Nikon. Though not as primitive as other non-communicative tribes, the Old Believers are stuck in their 17th century ways, refusing to join modern society. Throughout their history, the Old Believers had settled in China and Brazil, being forced to leave either due to local governments or harsh climates. Sects of the Old Believers have settled in an isolated pocket of Alaska, on the Kenai Peninsula, to preserve their antiquated beliefs and lives.
