How did the grimm brothers unite germany

two hundred years ago,  two young german librarians by the names of jacob  and wilhelm grimm published a collection of tales  that would become one of the most influential works  of folklore in germany, europe, and eventually the world.

between 1812 and 1857, seven editions of their tales  appeared,  each one different from the last, until the  final, best-known version barely resembled the first.  given that the first edition has recently been honored  in bicentenary celebrations throughout the world, it is perhaps a good time to reexamine what we think we know about the original tales of the brothers grimm.
