Mogadishu (Somalia Today) – Nicholas Haysom, the veteran South African diplomat whose brief but fraught tenure as the United Nations envoy to Somalia left a lasting imprint on the country’s politics, died in New York at the age of 73 on Wednesday, UN officials said on Thursday.
Haysom, a distinguished constitutional lawyer and mediator who most recently headed the UN mission in South Sudan, was remembered by UN Secretary-General Antonio Guterres as a “tireless peacemaker.”
His career took him from the halls of Nelson Mandela’s newly democratic South Africa to some of the world’s most complex and fragile conflict zones.
But in Somalia, Haysom is chiefly remembered for triggering one of the sharpest diplomatic ruptures between Mogadishu and the United Nations in recent history.
The Somalia fallout
Guterres appointed Haysom as his special representative for Somalia in September 2018.
At the time, the UN Assistance Mission in Somalia (UNSOM) played a central role in political support, security coordination and state-building.
But his time in Mogadishu ended abruptly within months. On January 1, 2019, Somalia’s federal government declared him persona non grata, ordered him to leave the country and accused him of deliberately interfering in internal affairs.
The bitter dispute followed Haysom’s direct intervention over the December 2018 arrest of Mukhtar Robow, a former Al-Shabaab deputy leader and spokesman who had defected and entered regional politics in South West state.
Ethiopian forces attached to the African Union mission arrested Robow, sparking deadly protests in the city of Baidoa.
In a stern letter to Somali authorities, Haysom openly questioned the legal basis of the arrest and asked what steps the government had taken to investigate the deadly violence that followed.
The row quickly escalated into a major public confrontation between the Somali government and the United Nations.
It drew deep international concern at a time when the Horn of Africa nation was still battling a fierce Islamist insurgency and struggling to steady fragile federal institutions.
The episode exposed wider simmering tensions between Mogadishu and regional administrations.
Local leaders had increasingly accused the federal government under then president Mohamed Abdullahi Mohamed, better known as Farmaajo, of trying to shape local political outcomes and centralise power.
The UN Security Council later expressed deep regret over Somalia’s unprecedented decision to expel the top envoy.
The council reaffirmed its backing for the UN mission while underscoring the sensitivity of international engagement in Somalia’s volatile internal political disputes.
A legacy of peacemaking
Although his Somalia posting was brief, it became one of the defining chapters of Haysom’s long diplomatic career in the Horn of Africa.
He later served as a special adviser on Sudan and southern Africa. In 2021, the UN appointed him head of the UN Mission in South Sudan (UNMISS), his final senior UN role.
During his tenure in Juba, Haysom repeatedly urged the country’s fractious leaders to implement a sluggish peace agreement and prepare for long-delayed elections, often warning the Security Council of the consequences of political inertia.
He remained at the helm of UNMISS until his death.
His passing comes as Somalia’s relationship with the United Nations enters a very different phase.
The long-running UNSOM political mission formally ended in October 2024, giving way to a smaller transitional presence as Mogadishu pushed successfully for a reduced international political footprint.
Before joining the UN, Haysom played a key role in South Africa’s historic democratic transition.
During the apartheid era, he worked as a prominent human rights lawyer and fought high-profile cases against the white minority regime.
He later served as Nelson Mandela’s chief legal and constitutional adviser from 1994 to 1999, helping to draft the nation’s widely praised post-apartheid constitution.
He also worked extensively on peace processes in Burundi and Sudan, earning a global reputation as a highly skilled behind-the-scenes negotiator.
But in Somalia, Haysom is likely to be remembered above all as the outspoken envoy whose insistence on human rights and due process collided with a fragile government determined to assert its sovereignty.
