Stockholm: Efforts by Colombian President Juan Manuel Santos to end five decades of war in his country were recognised with the Nobel Peace Prize on Friday.
The award came despite voters' shock rejection of the terms of a historic deal he reached last month with FARC chief Rodrigo Londono, alias Timoleon "Timochenko" Jimenez, after nearly four years of talks.
"The Norwegian Nobel Committee has decided to award the Nobel Peace Prize for 2016 to Colombian President Juan Manuel Santos for his resolute efforts to bring the country's more than 50-year-long civil war to an end," said committee chairwoman Kaci Kullmann Five.
Colombian President Juan Manuel Santos and FARC guerrilla leader Timoleon "Timochenko" Jimenez come from different worlds: one a rich businessman and politician; the other a country boy turned communist guerrilla.
Here are profiles of the conservative president and the Marxist guerrilla leader who brokered the end of half a century of conflict.
Santos: fighter for peace
Santos, 65, led a major offensive against the Revolutionary Armed Forces of Colombia (FARC) as defense minister from 2006 to 2009.
After becoming president in 2010, he shifted tack and negotiated for a settlement with the guerrillas.
"He made war as a means to achieve peace," said his brother-in-law and adviser, Mauricio Rodriguez.
"He weakened the FARC to make them sit at the negotiating table."
The peace drive "required courage, audacity, perseverance and a lot of strategy — those are Santos's strengths," Rodriguez added.
Despite fierce opposition to the talks from some former allies, Santos staked his presidency on the peace process.
"I am not looking for applause. I just want to do the right thing," he said.
He won reelection in 2014 in a vote widely seen as a referendum on the talks.
Santos is the scion of a wealthy, powerful family entrenched in Colombian politics and the media.
He has described himself as politically in the "extreme center."
He was educated at the London School of Economics and began his career as a journalist, covering the Sandinista revolution in Nicaragua as a young man.
He then switched to politics, serving in various ministerial posts.
Timochenko: Convict negotiator
The bearded, bespectacled FARC leader's real name is Rodrigo Londono, but he is better known by his noms de guerre Timoleon Jimenez and Timochenko.
He was born to a Christian mother and a communist father in a coffee-growing region where he says he soon became aware of social injustice.
"At school, I wondered why there were some classmates who went without breakfast while others lived wastefully," he once said.
He has said the first book he read as a child was the Bible but he also read Karl Marx's "Communist Manifesto" by the age of 12.
State intelligence services say he received military and medical training in the Soviet Union and Cuba, which he denies.
"Eighty-five percent of what they say about me is lies," he once told Venezuelan TV network Telesur.
The stocky Timochenko, 57, is renowned as a strategist and former intelligence chief in the FARC, which battled state forces for decades in the jungle.
He has been convicted in absentia for various attacks for which he has been sentenced to more than 150 years in jail.
He took over as FARC leader in 2011 after his predecessor, Alfonso Cano, was killed by the army.
The following year, he wrote to Santos proposing fresh peace negotiations after efforts by previous leaders had failed.
He agreed to Santos's demand that the FARC end its campaign of kidnappings.
As a guerrilla he often said: "I prefer to die on my feet than live on my knees."
But in recent peace talks he softened his tone. At Monday's signing he apologized on behalf of the FARC to all the victims of the conflict.
Asked recently what he has learned in his career as a guerrilla, he said: "There shouldn't be wars."
"He is one of the most well-liked guys in the FARC," Ariel Avila, an analyst at Colombia's Peace and Reconciliation Foundation told AFP.
"He is the man who will go down in history for bringing the FARC into the peace process."
