Hey XPTO,have u ever heard of the Battle of alcantara? yes, when Spain won the battle and the crowns of both countries were personally united until 1640.

the red hat answer me, why he can add the portuguese european territory and not their overseas possesions? because portugal belonged to the habsburg empire too? HAHAHAHAHAH LOL  !!! 
However, authors like the British historian Henry Kamen contend that these territories were never integrated into a Spanish state and instead formed part of the wider Habsburg possessions. Because of this, many historians use "Habspurg" and "Spanish" almost interchangeably when referring to the dynastic inheritance of Charles V or Philip II.

listen PAT, u british fanboys should know that Henry Kamen is a CLUELESS hispanophobe historian. He said that Spain never exist till the XX century HAHAHHAHA, what about the Ispania of Strabo, the Spania of Artemidorus,the Hispania of Livy ;  «Yo són I chomte d’Espanya que apela hom lo chomte de Barcelona» cronichles of Bernat Desclot (1256), the «Quatre reis que ell nomená d’Espanya, qui son una carn e una sang» of Ramón Muntaner (1265) (ESPANYA = Spain in catalan language)... stop believing in Kamen PROPAGANDA, all the spanish historians laughs at him. Also he lives in catalonia supporting the basque/catalonian nationalism.
