guerrillas of the Revolutionary Armed Forces of Colombia are struggling to reinsert themselves in civilian life in a nation where many people remain hesitant to forgive. Vast swaths of remote territory remain under the control of violent drug mafias and residual rebel bands.

‘‘Undoubtedly, for the peace process, this is an important test,’’ said Patricia Munoz, a professor of political science at the Pontifical Xavierian University in Bogota.

It was the first presidential election since the signing of the 2016 peace agreement ending Latin America’s longest-running conflict and was ultimately just as much about the divisive accord as it was deeply entrenched issues like persistent corruption and high levels of enduring inequality.

Petro energised young voters and drew millions to public plazas with his fiery speeches vowing to improve the lives of poor, disenfranchised Colombians. And though he failed to catch Duque, his more than 8 million votes marked the biggest ballot box success for a leftist presidential contender in a country where leftist politicos have long been stigmatised over fears of potential ties to guerrilla causes.

‘‘Perhaps as time passes people will be less scared about voting for Left-wing politicians,’’ said Jorge Gallego, a professor at Colombia’s Rosario University. ‘‘Although with this result, it’s proven that Colombia is still a Right-wing country.’’

Petro challenged Duque to break with his hard-line allies and promised to transform his considerable following into a vocal opposition that would push for social reforms and stand by the peace accord. –
