BBC: The amateur historians chronicling Delhi’s past on Instagram. “Mr [Umair] Shah, now 27, lives in Delhi where he works in digital marketing for fashion brands. But he’s also Sikkawala, or coin collector – that’s his moniker on Instagram where he documents fragments of history. To take to Instagram isn’t to reduce history to a mere snapshot. Mr Shah’s lyrical captions are steeped in facts and read like excerpts from an exciting story – where we learn about dead emperors, malevolent djinns and of rebellions that dissolved empires – in about 300 words.”
