In 1951 the Soviet government under Joseph Stalin carried out Operation North, a mass deportation that removed Jehovah's Witnesses from their homes and communities and sent them into internal exile in Siberia. The operation reached across the territories the Soviet Union controlled, meaning it did not remove a single congregation from one city alone but uprooted adherents wherever Soviet authority extended, resettling them in a remote interior the state used more broadly to isolate groups it had already decided to suppress.
Carried out by the Soviet state itself under Stalin's own government, the deportation was not an isolated act of local overreach but one measure inside a longer campaign the state waged against the movement over many years. That wider campaign, of which Operation North was a part, kept Jehovah's Witnesses formally banned inside Soviet territory for decades after the deportation itself had already concluded, a prohibition that persisted across changes in Soviet leadership long after Stalin's own death.
What this suppression changed for the movement's spread inside Soviet territory was containment rather than elimination. The formal ban held for roughly forty years, ending only with the Soviet Union's own collapse, so the deportation to Siberia marks not the movement's end inside the territory the Soviet state controlled but the opening act of a prohibition that would go on to outlast the very state that had imposed it.
