It’s often forgotten that Karl Marx fled Prussia and lived in the U.K. for nearly 40 years, where dire conditions shaped
everything he wrote, taught, and thought about revolution and the rights of man, which other leaders seized upon for their own uses. This excursion, fine for beginning economists, runs you past the landmarks of his life, many of which are still standing, and culminates at the British Museum, where he studied but you can run off and explore. The guide knows his subject, which makes this one headier than a lot of walking tours.
