This is an idea that came to me when reading and posting to kgauck's Warfare thread:http://www.birthright.net/forums/showthread.php?t=3572.

The holdings of many noble families (and also of religious orders) in the Middle Ages were often widely scattered across several realms. They could change hands as the result of marriages or feuds or through inheritances.

This could be a good minor event or even form the basis for an adventure.

For instance, suppose Sir Arundel, a minor landed knight in Ghoere and staunch supporter of the Baron is only distantly related to Lady Casiere, a minor noble controlling several manors in Roesone's Fairfield province. However distantly related they may be, Sir Arundel is Lady Casiere's only living relative and inherits her holdings after her death.
Suddenly, the regent of Roesone finds that a liegeman of her worst enemy has a say in her realm, however minor his influence might be.

Ruleswise, this might be handled similar to what I proposed in the Warfare thread:

Another interesting solution might be to grant the winner a law (0) holding - or even more law levels - within the attacked province.
For larger realms, a minor event like this would probably be of little concern to the ruler, but smaller realms might feel threatened, and rightly so.

Depending on the aims and acts of the new owner and the reaction of the province ruler, this event could easily develop into a Corruption/Crime, Brigands, Diplomatic Matter or even Great Captain event.

Btw, I couldn't think of a handy and fitting name for this event (hence the lame title of this thread), so suggestions would be welcome (as, of course, general feedback).
