Catalonia's ousted leader has called for peaceful opposition to Spain's decision to take direct control of the region.
Carles Puigdemont said he and other officials who were fired by the central government, will keep "working to build a free country".
The comments, made in a pre-recorded televised address, were a veiled refusal to accept his Cabinet's dismissal as ordered by central authorities.
The Spanish government's direct control of Catalonia became official on Saturday after dissolving the regional parliament and its government on Friday.
Mr Puigdemont and 12 members of the Catalan cabinet have been warned they could be charged with usurping others' functions if they refuse to obey the Spanish government.
The region had earlier passed the declaration of independence by a vote of 70-10 after opposition politicians in the 135-member parliament abstained and left the chamber.
Rival rallies were held on Friday night after vast pro-independence crowds had celebrated in the Catalan capital Barcelona - only to condemn the move from Madrid.
Smaller pro-unity groups came out in support of the Spanish authority being imposed.
The Spanish Senate approval of a proposal to trigger Article 155 of the constitution gave Madrid control over Barcelona.
It enables central government to take "all measures necessary" to intervene directly in the running of an autonomous region in the event of a crisis.
Prime Minister Mariano Rajoy has the backing of world leaders, with no country as yet supporting Catalan independence.
Downing Street said Britain will not recognise the Catalan parliament's declaration of independence from Spain.
