When former leftist rebel Gustavo Petro takes office as president on August 7, a key player in his administration will be Francia Marquez, his running mate in Sunday's runoff election.
Marquez is an environmental activist from La Toma, a remote village surrounded by mountains where she first organised campaigns against a hydroelectric project and then challenged wildcat goldminers who were invading collectively owned Afro-Colombian lands.
The politician has faced numerous death threats for her environmental work and has emerged as a powerful spokeswoman for Black Colombians and other marginalised communities.
"She's completely different than any another person that's ever had a vice presidency in Colombia," said Gimena Sanchez, the Andes director for the Washington Office on Latin America, a human rights group.
"She comes from a rural area, she comes from the perspective of a campesino woman and from the perspective of areas of Colombia that have been affected by armed conflict for many years.
"Most politicians in Colombia who have held the presidency have not lived in the way she has."
Sanchez said Marquez will likely be given a mandate to work on gender issues as well as policies affecting the nation's Afro-Colombian population.
In several interviews. Petro has discussed creating a Ministry of Equality, which would be headed by Marquez and would work across several sectors of the economy on issues like reducing gender inequality and tackling disparities faced by ethnic minorities.
Marquez said on Sunday part of her mission as vice president will be to reduce inequality.
"This will be a government for those with calluses on their hands," she said on stage while celebrating the election results with thousands of supporters at a popular concert venue.
"We are here to promote social justice and to help women eradicate the patriarchy."
Marquez grew up in a small home built by her family and had a daughter when she was 16, whom she raised on her own.
To support her daughter, Marquez cleaned homes in the nearby city of Cali and also worked at a restaurant while studying for a law degree.
Marquez entered the presidential race last year as a candidate for the Democratic Pole party, though she lost out in an inter-party consultation in March to Petro.
But she gained national recognition during the primaries and received 700,000 votes, topping most veteran politicians.
In speeches calling for Colombia to confront racism and gender inequalities, and to ensure basic rights for the poor, Marquez energised rural voters who have suffered from the country's long armed conflict as well as young people and women in urban areas.
"All of us who work with her now believe in the power of women," said Vivian Tibaque, a community leader in Bogota who worked on Marquez's campaign.
Political analysts said Marquez contributed to Petro's campaign by reaching out to voters who felt excluded by the political system but did not trust the leftist parties that Petro, a former member of a rebel group, has been a part of throughout much of his career.
They said her presence on Petro's ticket also motivated Afro-Colombian voters along the Pacific coast.
"I don't think Petro could've won the presidency without her." Sanchez said.
