Catalonia has their own economy, and their currency is called La Peseta, language which is Catalan, and their own customs. Their economy makes up more than 20% of what Spain makes.
The problem is that Catalonia is paying most of the taxes at high rate. The taxes are controlled by Madrid, a city in Spain. The Spanish government does not want to lower the taxes, as they help the poor.
Well it doesn't benefit us!!
I support it because it benefits me!!!
For Spain, this would impact them badly because they get most of their money to pay off debts from Catalonia, and without them, Spain would collapse.
Should Catalonia independesize from Spain? yes no
This led to a vote in which 90% of the people voted for independence from Spain.
However the referendum was claimed illegal by Madrid, who also fired Catalan officials and dissolved their parliament.
I am Carles Puigdemont, President of Catalonia! You can't catch me!
In June 2018, Catalan nationalists regained control of the region from Madrid's direct rule after a new government was sworn in.
