Kingdom of Castile, Kingdom of León, Crown of Aragon, Kingdom of Navarre, Kingdom of Granada,
House of Bourbon
(Anjou Branch),
Pillars of Hercules,
Imperial crown (Holy Roman Empire),
Spanish Royal crown
(Heraldic crown) are all in the code of arms and Castile,León, and Aragon all influenced the flag.
however some of these are just symbols and not kingdoms. such as House of Bourbon,
Pillars of Hercules/the straight of Gibraltar,
the Imperial crown, and the Spanish royal Crown. All the others are kingdoms however. Hope this helped. :)
