So, this is something I've been pondering for a while, in her marriage contract to Louis xiii, it was stipulated that should anne of Austria die a childless widow she would return to Spain and retain her inheritance rights and her dowry.
My question is this, say that Louis xiii dies in the 1610s without consummating his marriage, thus leaving anne a childless widow, who then does Anne marry? Louis brother? Or could Charles I be a possible contender?
