 The Kingdom of Castile conquered and incorporated the islands during the 15th century, although there were indigenous uprisings in later centuries.The Canaries acquired various special competences and privileges ("fueros"), including a tier of local government called "cabildos insulares" (island councils), which still exists and is now unique in Spain.Canarian nationalism arose in the later 19th century, led by Nicolás Estévanez, and others.
