Tens of thousands of Spaniards joined together in Madrid to protest against the continued imposition of austerity measures.
Demonstrators were protesting over issues including unemployment, poverty and official corruption.
They want the government not to pay its international debts and do more to improve health and education.
The BBC’s Guy Hedgecoe in Madrid says protesters travelled from all corners of Spain, many of them making the journey on foot, in order to voice their anger.
They called their protest the march of dignity, our correspondent says, because they say that the government of Mariano Rajoy is stripping Spaniards of just that.
For many of them, the cutbacks that Mr Rajoy has implemented, in particular to health and education, are causing Spain irreparable damage.
