Stand on Lea Bridge at low light and the river looks unremarkable, brown water sliding past concrete embankments, narrowboats moored gunwale to gunwale, the rumble of traffic overhead. Yet the River Lea is one of the oldest political boundaries in England. Iron Age Catuvellauni faced the Trinovantes across its valley. Alfred the Great and the Danish king Guthrum drew their treaty along its course in the 890s. When the Boundary Commission redraws London's parliamentary seats today, it still refuses to let any new constituency cross the Lea. The river has been arguing with the land for at least two thousand years and the land has never quite won.

Between Essex and Hertfordshire upstream, between London boroughs downstream, between communities that have looked across it at one another for sixty generations. In 894, Alfred the Great trapped a Viking fleet that had sailed up the river to Hertfo...
