King of Spades and Queen of Hearts, early 16th century.
The King of spades (K♠) is one of 52 playing cards: the King of the suit of Spades (♠).
Starting in the 15th century and continuing until the 19th, French playing card manufacturers assigned to each of the court cards names taken from history or mythology. In this context, the King of Spades was often known as King David or simply "David".
In tarot, the King of Spades is viewed as a dishonest lawyer.
It is representative of a person who is intelligent and authoritative in judgment, and is not easy to get along with.
