Juan Guaidó

Juan Guaidó Márquez is a Venezuelan politician from the Popular Will (Voluntad Popular) party who became internationally prominent in January 2019. Elected president of the opposition-controlled National Assembly on 5 January 2019, he invoked articles of the Venezuelan Constitution (notably Article 233) on 23 January 2019 to declare himself acting president, arguing that Nicolás Maduro's 2018 re-election was illegitimate.

Within days, the United States, Canada, most Lima Group members, and later a number of European Union states recognized Guaidó as interim president. Maduro retained control of the military, the Supreme Tribunal of Justice, and most state institutions, producing a prolonged dual-claim situation rather than a transfer of power.

Guaidó's tenure was marked by several setbacks:

• 30 April 2019: A call for a military uprising ("Operación Libertad") outside La Carlota airbase in Caracas failed to dislodge Maduro.
• Humanitarian aid standoff at the Colombia–Venezuela border in February 2019, which did not break the government's blockade.
• Gradual erosion of international recognition as elections, negotiations in Norway and Mexico, and internal opposition divisions wore on.

In December 2022, the main opposition coalition voted to dissolve the "interim government" structure that Guaidó headed, effectively ending his claim to the presidency as of 5 January 2023. He subsequently left Venezuela, traveling to Colombia and then the United States, citing threats to his safety.

Guaidó remains a reference point in debates over recognition doctrine, the limits of parallel governments, and sanctions policy toward Caracas. His case is frequently compared with other contested executives and is studied alongside the broader Venezuelan political and migration crisis, which has displaced millions since the mid-2010s according to UNHCR and IOM figures.
