River

The world's great rivers

20 places, each with its own page: where it is, how it came to be and what makes it special.

How these rivers were chosen

These are the rivers that shaped where people settled. Some are here because they are the longest, some because a civilisation grew up along them, and some because they carry more water than any other even though they are not the longest. Every continent that has great rivers is represented, which matters more than filling the list with the twenty longest.

A river's length is less settled than it looks. Rivers begin as many small streams, and choosing a different stream as the true source moves the total by hundreds of kilometres — which is exactly why the Nile and the Amazon still argue about which is longest. Where a figure is disputed, the page for that river says so, and gives both.

Every one of them stands on the globe

These pages are not only a list: every entry here has a place on the spinning globe, at its real coordinates. From far away the planet is a plain blue ball — detail only arrives as you zoom in, and then each of these is standing exactly where it belongs.

It works the other way round too: whatever you click on the globe opens its page, and every page links back to that exact spot on the globe. You can wander from a map into a text and back again without ever using the search box.
