Original: After the fall of Napoleon, Frederick William III of Prussia reasserted his rights by proposing that NeuchÃ cents tel be linked with the other Swiss cantons (the better to exert influence over the lot of them). On September 12, 1814, NeuchÃ cents tel became the 21st canton, but also remained a Prussian principality.
Simplified: It is the capital of Canton of NeuchÃ cents tel..
