Southern Samoyedic 'forest people' of the middle Ob, whose warrior confederation the Russians called the Piebald Horde for their multicoloured skin garments — the only Samoyedic people who held a fortified polity against the Cossacks.
Not an ending: after the Narym fortress went up in 1596 the Piebald Horde submitted, and a part of the Selkup withdrew north to the Taz and Turukhan, splitting the people into Northern and Southern groups separated by the Vakh Khanty and Elogui Ket. Roughly 3,600 Selkup were counted in the late Soviet censuses; they remain a recognized Indigenous small-numbered people of the North.
The Finnish ethnographer's field account of the Selkup and neighbouring Samoyeds on the Ob and Taz — the classic firsthand description of this people.
Used for the Narym/Piebald Horde campaign and the northward Selkup retreat it caused.
