Colombia's Marxist FARC rebels have officially declared their disarmament complete, marking an end to their role in a 50-year fight with the government.
The guerilla group handed in its weapons as part of a 2016 peace agreement under United Nations supervision.
At a ceremony in a rebel camp in mountainous south-east Colombia, old enemies came together to officially lay the past to rest.
All but a few of the guerilla force's weapons were handed over to United Nations monitors to eventually be moulded into a monument for peace.
The Revolutionary Armed Forces of Colombia, also known as FARC, are now hoping to become a legally recognised political party.
Colombian president Juan Manuel Santos has talked of his hopes for the country's future.
"Without weapons, without violence, we are no longer a nation at war with itself, we are no longer a story of pain and death. We are one population and one nation, advancing towards the future within the blessed cause of democracy."
More than 220,000 people have been killed and millions displaced during the half-century conflict.
A United States-supported offensive launched in 2002 by former president Alvaro Uribe forced the group, primarily financed by drugs, kidnapping and extortion, into Colombia's jungles.
Several attempts at lasting peace fell apart, but a renewed push by President Santos -- awarded the Nobel Peace Prize for his efforts -- led to a final accord in late 2016.
Most of the around 7,000 former fighters have agreed to continue as a political movement.
The FARC leader, known as Timochenko, says the group will endure.
"Today does not mean that the FARC is ceasing to exist. In reality, what we are putting an end to is our 53-year-long armed uprising. But we will continue to exist as a legal, democratic movement that develops its ideological, political, organisational and propaganda programs by exclusively lawful means."
Some critics of the agreement say it is too lenient on the rebel forces, with suspects to be tried in special courts with the possibility of receiving amnesties or reduced sentences.
FARC itself has also complained of delays in getting close to 3,400 members out of jail.
Colombians rejected the peace accord in a referendum before it was redrafted and pushed through congress.
The head of the UN Peace Mission in Colombia, Jean Arnault, has praised the pact's symbolism.
"In a world convulsed by old and new forms of violence, by conflicts whose protagonists appear irreconcilable from unprecedented movements of the displaced and refugees, a successful process constructing peace in Colombia is also reason for hope and a powerful example for the international community."
Colombia's leaders are now hoping to make a similar agreement with the National Liberation Army, or ELN.
Despite talks starting in February, progress has been minimal, with the group coming under suspicion for a June 17th shopping-centre bomb attack in which three people died.
For now, President Santos has urged all members to live up to the agreement's promises.
"Let us live up to the heights of peace which we have achieved. Let us live up to the dreams of our children, who look at us with eyes full of hope. Let us live up to history. We must not let ourselves lose this moment and this achievement which belongs to all of us, to all Colombians. We are one people, we are one nation. Long live peace."
