Lawsuit
In 2000, Karl Emich began the final round of a lawsuit to inherit ₤100 million worth of castles, property, and a Mediterranean island that had been previously denied him by his family because he chose to marry Thyssen. Karl Emich was disinherited shortly after his 1991 wedding, as his mother, father, and brother Andreas disapproved of her birth. He also broke a 1897 family edict which stipulates that its members may only marry aristocrats of equivalent status. Karl remarked about the whole affair,
"From the very beginning of our marriage I was turned into an enemy. We were both subjected to enormous pressure. No marriage can withstand that sort of thing in the long term. I had hoped things would improve when our child arrived. But after our daughter was born, nothing happened. My mother has refused to speak to me since the wedding".
Karl Emich has insisted that the stress this feud put upon his marriage is the reason why Thyssen left him, converted to Islam, and ran off with Aga Khan IV.
