Racism in Spain (Spanish: Racismo en España) can be traced back to any historical era, during which social, economic and political conflicts have efficiently been justified by racial differences, be it in the form of racism as an ideology or in the form of racism as simple attitudes or behaviors towards those who are perceived as being different. More common than racism per se are the attitudes linked to xenophobia and nationalism (specially the Spanish, the Catalan and the Basque ones), as well as religious and/or linguistic-cultural hatred.
