spanish "duchess" leaves huge historical archive and palace to wife

i found this article on luisa isabel fascinating. what an interesting life... from the article:

"The dictator Francisco Franco jailed her for championing workers, who nicknamed her the "Red Duchess". She challenged Spain's official history, arguing that Columbus didn't discover America. She was an atheist, a republican and reckoned her 13th-century ancestor Guzman el Bueno, ennobled for fighting the Moors, was a north African whose grandmother was black."
