Interesting reference to the European monarchies major dismissals. Catalonia has been pushed to the limit by "the Great Spain" ideology from which  the party in power gets most of its voters.  Any concesions to Catalonia are seen as a sin, no matter how reasonable the Catalans may be. Politicized judges are used instead of  negotiations. There would be no demand for a Referendum if the pacted reforms to the Catalonia Autonomous Statute ratified by the last President of Spain Rodriguez Zapatero had been respected.
