Europe’s major rivers do not meet (unless you count the Sava, which drains into the Danube in Belgrade). This partly explains why there are so many countries in what is a relatively small space. Because they do not connect, most of the rivers act, at some point, as boundaries, and each is a sphere of economic influence in its own right; this gave rise to at least one major urban development on the banks of each river, some of which in turn became capital cities.
