Crown of Castile
The Indies remained in an ambiguous state from the death of Philip in 1506 to the death of Ferdinand in 1516, being half a personal property of the kings (a "lordship" with absolute power for its lord), and half a kingdom of the Crown (ruled under the laws of the Crown of Castile). From 1516 to 1520 the Indies were extraofficially part of the Crown of Castile. On July 9, 1520 Charles V, Holy Roman Emperor incorporated them explicitly into the Crown of Castile and he forbid any future separation.
