In a small classroom in western China, children once learned to sing and count in the language of their ancestors — Uyghur. Then the doors were locked, and founder Abduweli Ayup went from teacher to enemy of the state. We return to the first episode in our series, ERASED.

ERASED is a four-part investigation into how China is wiping Uyghur culture from existence — one law, one app, one person, one website at a time. From shuttered schools to vanishing websites, ERASED uncovers an authoritarian regime’s campaign to delete a culture — and the unlikely rebels racing to stop it.
