(CNN)When Xiomara Castro led a march through the Honduran capital in 2009, demanding that her husband, who was ousted in a military coup, be returned to power, it was the first time she seized the political spotlight, according to Honduran political experts CNN spoke to for this article.
From first lady to first female president: Meet the new Honduran leader Xiomara Castro
Now, the former first lady is ready to take center stage as Honduras' first female president, promising a radical agenda to counter years of governance plagued by corruption and scandal.
Castro, a democratic socialist, will be inaugurated on Thursday following a landslide victory in the November 2021 presidential elections.
Her party, the Freedom and Refoundation Party (Libre) won the vote with a lead of more than 14 points over her nearest opponent, Nasry Asfura, the capital's mayor and candidate for outgoing President Juan Orlando Hernández's National Party.
Winning 51% of the vote share and 1.7 million votes, Castro garnered the largest number of votes in the country's history, underscoring the public's appetite for change.
The 62-year-old ran on campaign promises to battle corruption (and promised to enlist the United Nations to strengthen that fight), alleviate poverty and liberalize abortion laws.
But a recent shakeup within Castro's own party could mean she might not be able to fulfil that agenda.
On Sunday, a group of Libre lawmakers rebelled over Castro's pick for congressional speaker, leading to a split in the newly-elected Congress that could potentially see the National Party taking back control of the legislature.
That fracture means that Castro is facing a reality of leading the country without the support of her some of her party and its allies in Congress -- days before she even is inaugurated.
Castro's path to power has never been easy, however. It took her two failed campaigns in 2013 and 2017 before making it to the top post in Honduras, one of Latin America's most conservative countries -- with few female elected officials.
CNN reached out to Castro for this article. Her team told CNN that she was not giving interviews before her inauguration.
Born in the capital Tegucigalpa, Castro dedicated her early years to family life, marrying businessman and politician Manuel Zelaya at the age of 19 and later raising their four children while managing his businesses, according her Libre Party website.
When Zelaya took office in January 2006, Castro had no other political ambitions than to accompany him and to support his work, sociologist Julio Raudales of the National Autonomous University of Honduras (UNAH) said, playing an active role in social programs that included early education initiatives and HIV/AIDS advocacy work.
An unexpected twist in 2009 would change their lives. Zelaya was abducted from his house by military officers in a coup over a planned referendum on constitutional reform that would allow the president to be re-elected for a second term. Zelaya was taken to Costa Rica in his pyjamas. When he returned to Honduras in May 2011, he founded the Libre Party.
Then-United States President Barack Obama called the turmoil a step backward from the "enormous progress of the last 20 years in establishing democratic traditions in Latin America."
Meanwhile, Castro took the helm as leader of the resistance movement that demanded Zelaya's return to office. It was from that incident that her political career took shape, Raudales said.
Before then, Castro was seen as "just the wife of a former president," lawyer and political analyst Raul Pineda said.
Her election victory marked a watershed moment in Honduran politics, said Raudales.
"At a time when Honduran democracy was highly questioned, Castro managed to show that you can defeat a lot of opposition if you work properly and get the sympathy of the population in Honduras," he said.
