BARCELONA, Spain — Hundreds of thousands of Catalans took to the streets of Barcelona on Sunday to voice their opposition to the region’s declaration of independence amid vast political uncertainty for the region in northeast Spain.

Catalonia’s political leadership was fired Saturday by central authorities in Madrid who are trying to tame the worst political crisis Spain has seen in decades. So far, Catalan’s former leader has insinuated that he won’t step down.

Waving Spanish, Catalan and European Union flags, the protesters described themselves as the silent majority who have been ignored during the wealthy region’s bid for independence, which came to a head Friday when the regional parliament voted to secede from Spain.

“We have organized ourselves late, but we are here to show that there is a majority of Catalans that are no longer silent and that no longer want to be silenced,” said Alex Ramos, head of the Catalan Civil Society, a pro-union grassroots group.

The organizers said more than 1 million people turned out but police put the figure at 300,000. There was no way to immediately reconcile the figures.

The mood at Sunday’s rally was festive. “We won’t let Spain be torn apart into pieces,” read one banner. “The awakening of a silenced nation,” read another.

In response to the lawmakers’ secessionist vote, Spanish Prime Minister Mariano Rajoy triggered unprecedented constitutional powers, firing Catalonia’s secessionist regional government and calling an early regional election for Dec. 21.
