The King Pigeon was developed in the United States in the 1890's by crossing four older varieties, specifically:
----the Duchess for grace
----the Homer for alertness,
----the Maltese for compactness and style, and
----the Runt for body and size.
King Pigeons - along with other varieties of domesticated pigeons - are descendants from the Rock Pigeon (Columba livia).
