Catalonia declared independence from Spain less than an hour before a vote in the country’s Senate gave Madrid the power to seize the region’s autonomous powers.
The vote in the regional parliament followed a tense week of last-ditch negotiations between Madrid and Barecelona. Seventy of 135 Catalan deputies voted for independence, with 10 opposed and two blank ballot slips.
Opposition lawmakers had walked out of the chamber ahead of Friday’s vote in protest.
Rounds of applause broke out in the chamber as members of the parliament hugged and shook hands.
Thousands of people watched the voting process and the counting live on big screens outside Catalonia’s parliament in Barcelona, and cheered and danced after the motion was passed.
The motion calls for beginning an independence process that includes drafting Catalonia’s new top laws and opening negotiations “on equal footing” with Spanish authorities to establish co-operation.
On Thursday Catalan president Carles Puigdemont had ruled out calling a snap election, thought to have been a potential way of defusing tension with the central government.

Mr Puigdemont said he had not received sufficient guarantees that Madrid would hold off on its attempts to take control of the region.
Spain’s prime minister, Mariano Rajoy, tweeted immediately after the vote calling for calm. He said the rule of law would be restored in Catalonia.
Spain’s senate voted on Friday, shortly after the Catalan independence vote, to trigger Article 155 of the constitution and allow the imposition of direct rule.
The vote will give Madrid the authority to govern Catalonia is the first direct intervention by central authorities in the affairs of one of the country’s 17 autonomous areas.
Mr Rajoy will have the power to sack Mr Puigdemont and his cabinet among other measures. Mr Rajoy is understood to be planning immediately to enact the Article 155 provisions during an urgent meeting on Friday afternoon.
The crisis stems from an independence referendum, held earlier this month, that Spanish judges had declared unconstitutional.
Before it went ahead Madrid authorities confiscated ballot papers and closed polling stations, with clashes erupting in the streets.
An overwhelming majority of those who did vote favoured secession, but turnout was low and there is a substantial section of the Catalan population that wants to remain a part of Spain.
Following Friday’s independence vote, European Council president Donald Tusk said “nothing changes” for the EU, adding it would continue only to deal with the Madrid government.
Mr Tusk urged Spain to favour “force of argument, not argument of force” in addressing the independence declaration.
The United States said Catalonia was an “integral part of Spain” and that it supported Spanish government efforts to keep the nation “strong and united.”
State Department spokeswoman Heather Nauert said the two NATO allies “cooperate closely to advance our shared security and economic priorities.”
