Roger Casement

He was a knight of the realm who exposed the genocide in Leopold's Congo, an Anglo-Irish Protestant who became a republican revolutionary, and the only one of the 1916 leaders who was genuinely famous outside Ireland before the Easter Rising began. The British government that had knighted him in 1911 hanged him in 1916. W.B. Yeats wrote that his ghost was beating on the door. He was fifty-one years old, and the priest who received him back into the Catholic Church an hour before his execution said the world should be praying to him.

Sandycove to the Congo: A Diplomat Made by Empire

Roger David Casement was born on 1 September 1864 at Doyle's Cottage, Sandycove, County Dublin — a house on the seafront that no longer exists. His father, Captain Roger Casement of the 17th Light Dragoons, was a Protestant from County Antrim with a distinguished military career; his mother, Anne Jephson, was from a Church of Ireland family. Both parents died young — his mother when he was nine, his father when he was thirteen — and Casement was raised in County Antrim by his father's family. He was educated partly in England, attended the Church of Ireland in his youth, and moved to Liverpool at sixteen to work for the Elder Dempster shipping company, whose trade routes across the Atlantic took the young Casement toward West Africa and his life's vocation.

At the age of twenty he was working in the Congo Free State, King Leopold II of Belgium's personal colonial possession — in theory a humanitarian enterprise, in practice one of the most brutal systems of forced labour and mass murder in the history of European imperialism. Leopold's agents collected rubber quotas from Congolese villages by taking women hostage and returning them only when the quota was met; the hands of workers who failed to meet their quota, or of those who were killed by company soldiers, were cut off and presented to supervisors as proof of execution. Soldiers who fired their rifles were required to produce a severed hand for each bullet expended, to prove they had not wasted ammunition. Casement witnessed these practices, documented them, and spent years building the case that would eventually produce his 1904 report to the British government.

The Congo Report, published in 1904, documented the atrocities in specific detail and was the most important single document in the campaign for Congo reform. It led directly to a major reorganisation of Belgian rule in the Congo in 1908 and established Casement's international reputation as a humanitarian investigator of the first rank. He subsequently conducted an investigation into the Putumayo rubber estates of the Peruvian Amazon, where the Peruvian Amazon Company — with British shareholders — was operating an almost identical system of forced labour and murder against indigenous peoples. His Putumayo Report of 1912 earned him a knighthood from King George V. He was the most decorated humanitarian in the service of the British Crown.

The Turn: Imperialism Seen From Within

What Casement saw in the Congo and in the Amazon transformed him. He had gone to Africa as a loyal employee of imperial commerce, working for companies with British backing in territories ruled by European powers. He came away convinced that the logic of empire — the treatment of colonised peoples as instruments for the extraction of wealth rather than as human beings with rights — was not an aberration of a handful of bad actors but the structural reality of the system. The exploitation he documented in the Congo was what empire looked like from the perspective of the people it colonised. And Ireland, he began to understand, was colonised too.

He had always had Irish nationalist sympathies — he had been raised in the north by a Protestant family with strong Ulster identity, and his mother was said to have had him secretly baptised as a Catholic as a child, though this was not discovered until later. His involvement with the Irish nationalist movement began seriously after his return from Africa. He joined Sinn Féin — then a moderate home-rule organisation rather than the revolutionary force it later became — when it was founded in 1905. He was deeply involved in the founding of the Irish Volunteers in November 1913, contributing both organisational energy and funds. He retired from the British consular service in 1913 on grounds of ill health and devoted himself entirely to the Irish cause.

Germany and the Mission That Failed

When the First World War broke out in August 1914, Casement was in the United States attempting to raise funds and international support for Irish republicanism. He made contact with the German embassy, and in October 1914 travelled to Germany via Norway and the United States — a journey of extraordinary difficulty in wartime — to negotiate German support for an Irish rising. He spent over a year in Germany, pursuing two objectives: securing a formal agreement of German military support for Irish independence, and recruiting Irish prisoners of war held in German camps to an Irish Brigade that would fight against Britain. He largely failed at both.

The German government signed an agreement in December 1914 committing to the recognition of an independent Ireland if Germany won the war, and promising military support — but in practice delivered only 20,000 obsolete rifles and ten machine guns, loaded aboard the Aud under Captain Karl Spindler. The Irish Brigade, which Casement hoped might reach brigade strength, attracted only fifty-three recruits from the thousands of Irish prisoners of war available. Most Irish POWs were loyal to Britain, contemptuous of Casement's mission, or simply unwilling to risk death as traitors. By early 1916 Casement had concluded that Germany would not provide the troops and artillery the rising required, and that the rising, if it proceeded, would fail militarily. His primary purpose in returning to Ireland in April 1916 was to stop it, or to delay it until adequate German support was secured. He arrived too late for either.

He was put ashore at Banna Strand, County Kerry, from a German submarine on 21 April 1916, three days before the Rising. The Aud, intercepted by the Royal Navy, was scuttled by her captain before she reached Kerry. Casement was found hiding in an ancient fort near the strand within hours of his landing, arrested by the Royal Irish Constabulary, and taken to London. He was in Brixton Prison, then Pentonville, when the Easter Rising broke out and was suppressed without the German arms he had failed to deliver.

Trial, the Black Diaries, and Execution

Casement was charged with treason under a 1351 statute, the prosecution led by Lord Birkenhead — who had himself played an active role in forming the Ulster Volunteers to resist Home Rule, a fact that underscored the political nature of the proceedings. His defence team of George Gavan Duffy, A.M. Sullivan, and Artemus Jones was outmatched. The trial was conducted fairly in a technical sense, but in a legal and political environment — wartime London, with fifteen executed leaders of the Easter Rising already making international headlines — that made acquittal impossible. He was convicted on 29 June 1916 and sentenced to death.

The campaign for clemency was substantial and international. Arthur Conan Doyle, W.B. Yeats, George Bernard Shaw, and the United States Senate all petitioned for a reprieve. The British government, aware that Casement was the most internationally famous of the 1916 leaders and that his execution would damage American opinion — America was still neutral, and Britain desperately needed to bring her into the war — was genuinely worried about the political consequences. The solution was the Black Diaries. Government agents circulated privately to influential journalists, politicians, and American opinion-formers extracts from diaries found among Casement's possessions that detailed homosexual activities in explicit terms. In the climate of 1916, where homosexuality was a criminal offence and widely regarded as a mark of moral degeneracy, the circulation of the diaries was sufficient to destroy the clemency campaign. Conan Doyle could not believe the diaries were genuine. Yeats refused to be moved by them. Most others were. The appeal was dismissed.

The authenticity of the Black Diaries has been disputed since their circulation. Irish nationalists for decades insisted they were British forgeries, fabricated specifically to destroy support for clemency. A forensic handwriting analysis conducted in 2002 concluded that Casement had written them. The scholarly consensus today accepts their authenticity, understanding Casement as a gay man who documented his homosexual relationships in private journals that the British state weaponised against him. The use of the diaries — regardless of their authenticity — was, as the historian Angus Mitchell and others have argued, a reprehensible act of state manipulation, deploying private sexuality as a tool of political assassination. On 3 August 1916, Roger Casement was hanged at Pentonville Prison. He had received back into the Catholic Church by the prison chaplain Father Thomas Crotty an hour before his death. Crotty said: we should be praying to him, not for him.

Repatriation and Legacy

Casement's remains were buried in quicklime in the grounds of Pentonville Prison — the same treatment given to the other Irish executed leaders and to common criminals. The Irish government from the 1950s onwards pressed the British government for repatriation. In 1965, following negotiations by Éamon de Valera's government, Casement's remains were returned to Ireland. He was given a state funeral attended by de Valera himself — the last surviving commandant of the Easter Rising — and was reinterred in the Republican Plot at Glasnevin Cemetery, beside other leaders of Irish independence.

His legacy spans multiple traditions. For Irish republicans he is one of the sixteen executed leaders of 1916 and a Protestant who gave his life for Irish freedom. For the international human rights movement he is described as the father of twentieth-century human rights investigations — the man who pioneered the methodology of documentary investigation of atrocity, government report, and international campaigning that remains the basis of human rights work today. For historians of sexuality he is a figure whose private life was used against him by a state that regarded it as disqualifying, and whose rehabilitation required the world to change its mind about what kind of love a man is allowed to have. W.B. Yeats's poem, written in outrage at the use of the diaries, declared that the ghost of Roger Casement was beating on the door. More than a century after his death, the door is still worth examining.
