>>14938399Celts were the westernmost group of indo-europeans, descended from the expansion of horselords from the pontic steppe who were also the progenitors of the goths and scythians and vedic peoples. Celts specifically had their start running a salt mining empire from Halstatt and expanding westward from there.
It's important to remember that celtic is a broad term applied to a lot of peoples who were probably very distinct, celtiberians and the ancient irish for example are considered celtic cultures but were regionally distinct.
