The last generations of the royal family of this once so civilized ancient kingdom were completely perverted and lived an indecent and decadent life.
As a result, the people began to revolt. The kingdom collapsed after the angry mob charged the palaces, and a bloody end was put to the repulsive regime. No members of the royal family survived.
During the second decade of the 20th century, c0mrade L. saw some pictures in a naughty history book and decided to undertake action.
Moral of this story: read your naughty history books at school and learn from it!
