The mission:
Kill of [a] enough members of a ruling family to place an [c] outsider on the throne.
The tasks:
a) Find a plausible way (accidents preferred) to get rid of everyone in the line of succession in one sweep. To be considered: Why is everybody (even baby’s/toddles when in the LoS) on the spot. You need a death rate of ~90% (some spouses/attendants may survive).
b) The targets are post 1900 European royals, but others can bee considered too.
c) The new monarch should be some kind of misfit or lead to an exceptional situation.
