Hailed as "la libertadora," in an allusion to Venezuela's historic independence hero Simon "The Liberator" Bolivar, Machado was given the Nobel Peace Prize on Wednesday.

But it was her daughter Ana Corina Sosa Machado who attended the ceremony in Oslo and read out the acceptance speech from the opposition leader declaring Venezuelans ready to "fight for freedom."

Machado, 58, was barred from challenging Maduro in July 2024 elections and went into hiding after the vote, which the opposition and much of the international community accuses Maduro of stealing.

But she remained a tireless democracy campaigner on social media, where she regularly posts videos assuring Venezuelans that change is near at hand.

Clad in jeans and a white shirt, Machado toured Venezuela last year to campaign for an end to a quarter century of increasingly repressive socialist rule. Her rousing speeches frequently move supporters to tears.

She won an opposition primary with 90 percent of votes cast in 2023, but was promptly declared ineligible by authorities loyal to Maduro.

Machado accepted to take a political back seat and campaign instead for her last-minute stand-in: little-known former diplomat Edmundo Gonzalez Urrutia.

The opposition's tally of ballots from polling stations showed Gonzalez Urrutia easily defeating Maduro in the election -- but the socialist incumbent was proclaimed the winner, sparking deadly riots which were brutally repressed.

Gonzalez Urrutia went into exile after a bounty was placed on his head. Machado stayed behind to lead the resistance.

After months of hiding she briefly re-emerged on the eve of Maduro's inauguration for a third term in January to address an opposition rally.

"We are not afraid," she declared, before fleeing cloak-and-dagger style on the back of a motorcycle to avoid arrest.

- US strikes -

The Nobel award comes at a critical moment in a tense standoff between the United States and Venezuela.

President Donald Trump has ordered a major military deployment in the southern Caribbean, near Venezuela, and greenlighted US strikes on suspected drug boats that have killed dozens of people.

Washington, which recognized Gonzalez Urrutia as Venezuela's rightful leader, accuses Maduro of leading a drug cartel.

Machado has backed the US military pressure on Maduro as a "necessary measure" towards a democratic transition in Venezuela.

- 'Bring our children home'

An engineer by training, Caracas-born Machado entered politics in 2002 at the head of the association Sumate (Join us), pushing for a referendum to recall Maduro's mentor, the late socialist leader Hugo Chavez.

She was accused of treason over the referendum call and received death threats, prompting her to send her two young sons and daughter to live abroad.

In parliament, she confronted the firebrand Chavez.

"Expropriating is stealing," she told him in 2012, referring to his seizures of hundreds of domestic and foreign-owned businesses.

Banned from flying during last year's election campaign, she crisscrossed the country by road, wearing rosary beads around her neck.

"We're going to liberate the country and bring our children home," she said, vowing an end to Maduro's rule -- and with it a severe economic crisis that has prompted over seven million people to emigrate from the once prosperous, oil-rich state.

In October, she and Gonzalez Urrutia were awarded the European Union's top human rights prize for having "fearlessly upheld" the values of justice, democracy and the rule of law.
