The Catalan government remained defiant on Sunday, stating it would not accept Madrid's plan of direct rule.
Almost a half a million Catalans came out in protest the day before, demonstrating against the suspension of autonomy following Catalonia's referendum on independence.
"The Spanish government was acting against the democratic will of the Catalans after refusing all offers of dialogue," the Catalan leader, Carles Puigdemont said.
Meanwhile, Spain's foreign minister rejected accusations of a 'coup' by Madrid.
"If anyone has attempted a coup, it is the Catalan regional government," Mr Dastis was quoted by the BBC as saying.
