There was a horrible slaughter of the Waldensians that killed the majority of them, but there was a remnant. There is a Waldensian Church in Valdese, NC, a town established by Waldensians. They settled there en masse a little over a century ago, after leaving the Cottian Alps of northern Italy due to ongoing restrictions and persecution against them there.
Thanks for the update. Nice to know a very small remnant survived. They were all over southern France, northern Italy and Switzerland. All serious historians now agree that the Waldensian movement began in Lyons about 1170. The Inquisition was also used against the church’s other opponents.
