The East End in 1900 - a world of cobbled streets and thick fog. Thousands of Londoners live in cramped, sooty tenements. Their homes are lit by gas and infested with lice. Amidst this dire poverty is a close-knit community defined by resilience, kindness and humour. Children play in the streets and the men crowd to the dock gates for work. From the match factories of Bow to the hop fields of Kent, see how London's East End lived in the years before the Second World War.
