The 1866 banking crisis effectively ended London’s iron shipbuilding industry. Few companies survived, so destitution faced many shipyard workers. Processing industries also changed. Beet sugar replaced cane, soft sugar hard ‘baked’ sugar and production became concentrated in two firms. In contrast, boosted by foreign grain imports, London’s milling industry expanded. South bank maritime communities maintained established industrial patterns. Shipbuilding proved resilient and traditional employment systems persisted in the Rotherhithe docks, but settlements of waterfront wharf labourers, many of Irish origin, were desperately poor. Poverty was also a hallmark of the north bank. Less socially mixed than in the past, mythic undifferentiated images of ‘Outcast London’ obscured the East End’s continuing maritime connections, including the presence of skilled workers and their organisations. Sailors ashore, the subject of State intervention, were an exception.
