The friction between madrid and <insert almost any of the other spanish cities> goes back to the Civil War days. This is the consequence of the Franco dictatorship and its repressive policies (i.e. you're not allowed to use your own language). Those wounds were never healed because the repressors were never judged and tried (unlike in Germany or Argentina).
