Maria Corina Machado has led the struggle for democracy in the face of ever-expanding authoritarianism in Venezuela. Ms Machado studied engineering and finance, and had a short career in business. In 1992 she established the Atenea Foundation, which works to benefit street children in Caracas.Ten years later she was one of the founders of Súmate, which promotes free and fair elections and has conducted training and election monitoring. In 2010 she was elected to the National Assembly, winning a record number of votes. The regime expelled her from office in 2014. Ms Machado leads the Vente Venezuela opposition party and in 2017 helped found the Soy Venezuela alliance, which unites pro-democracy forces in the country across political dividing lines.In 2023 she announced her candidacy for president in the 2024 presidential election. When she was blocked from running, she supported the opposition’s alternative candidate, Edmundo Gonzalez Urrutia. The opposition mobilised widely and collected systematic documentation that it was the true winner of the election. The regime declared victory and tightened its grip on power.Ms Machado is receiving the Nobel Peace Prize first and foremost for her efforts to advance democracy in Venezuela. But democracy is also in retreat internationally. Democracy – understood as the right to freely express one’s opinion, to cast one’s vote and to be represented in elective government – is the foundation of peace both within countries and between countries.
